The following describes the technical scheme of the embodiment of the present application in detail with reference to the accompanying drawings.
Fig. 1 is a schematic structural view of an indwelling needle connector fixing patch according to an embodiment of the present application, and fig. 2 is another schematic structural view of an indwelling needle connector fixing patch according to an embodiment of the present application.
Referring to fig. 1 and 2, the indwelling needle hub fixing patch 100 includes an adhesive layer 110, a supporting layer 120, at least one set of fixing bands 130, and a fixing ring 140.
The adhesive layer 110 is mainly used for adhering to the surface of a human body. That is, the indwelling needle hub fixing patch 100 realizes an attaching function by the attaching layer 110, and thus the indwelling needle hub fixing patch 100 can be directly attached to the surface of the human body. In some embodiments, the adhesive layer 110 may be a hydrocolloid dressing or a transparent film dressing. It is understood that the adhesive layer 110 may be any of a hydrocolloid dressing or a transparent film dressing, and thus the adhesive layer 110 may have an adhesive effect as well as skin-friendliness.
The supporting layer 120 is disposed on one side of the adhesive layer 110, wherein the supporting layer 120 is used for supporting the indwelling needle connector. It will be appreciated that the support layer 120 may be disposed on a non-adhesive surface of the adhesive layer 110, and that the catheter adapter is disposed on the support layer 120 when the catheter adapter is secured to the catheter adapter mount. In some embodiments, the supporting layer 120 may be made of a silica gel material, so that the silica gel material is used to provide flexibility, so that the combination degree of the supporting layer 120 to the indwelling needle connector can be improved, the fixing effect of the indwelling needle connector on the supporting layer 120 is improved, meanwhile, the pressing of the indwelling needle connector on the human body when the indwelling needle connector is fixed on the indwelling needle connector is effectively slowed down, and the comfort of a patient is improved. In some embodiments, the adhesive layer 110 is provided with a plurality of ventilation holes, wherein the ventilation holes are wound around the adhesive layer 110, and the ventilation holes are used to further improve the comfort of the patient when the patient uses the indwelling needle connector to fix the patch 100.
At least one set of fastening strips 130 and fastening rings 140 are disposed on the surface of the support layer 120. Wherein the same set of fixing straps 130 and fixing rings 140 are distributed along the same straight line. That is, the fixing bands 130 may be in one-to-one correspondence with the fixing rings 140. The fixing band 130 has a fixing end 131 and a limiting end 132, wherein the fixing end 131 is fixedly connected with the supporting layer 120, and the limiting end 132 is configured to detachably pass through the fixing ring 140, wherein when the limiting end 132 passes through the fixing ring 140, a fixing space for fixing the indwelling needle connector is formed between the fixing band 130 and the supporting layer 120. That is, when the indwelling needle adapter is fixed to the indwelling needle adapter fixing patch 100, the indwelling needle adapter is at least partially fixed in the fixing space.
In order to facilitate understanding of the technical solution of the present application, the following describes in detail the method for using the indwelling needle connector fixing patch 100 of the present application:
fig. 3 is a schematic view showing the use of the indwelling needle connector fixing patch according to the embodiment of the present application.
Referring also to fig. 3, when the needle portion of the indwelling needle is in use, i.e., after the puncture of the human body is completed, the medical dressing 200 is typically used in the area corresponding to the needle portion of the indwelling needle to secure and protect the needle portion of the indwelling needle. The indwelling needle connector fixing patch 100 according to the present application may be attached to one side of a medical dressing when in use. For example, when the needle of the indwelling needle is applied to the back of the hand of the human body, the indwelling needle connector fixing patch 100 of the present application can be stuck to the back of the hand close to the forearm of the human body. Removal of the indwelling needle hub mounting patch 100 may be accomplished by tearing the indwelling needle hub mounting patch 100 from the surface of the human body.
When the retaining needle head is fixed, firstly, the retaining band and the retaining ring are ensured to be in an open state, namely, the limiting end 132 of the retaining band does not penetrate through the retaining ring 140, the retaining needle head is placed on the supporting layer and positioned between at least one group of retaining bands and the retaining ring, then the limiting end 132 of the corresponding retaining band penetrates through the retaining ring 140, so that the retaining needle head is at least partially fixed in a fixing space formed between the retaining band 130 and the supporting layer 120, the retaining needle head is fixed, and when the retaining needle head is unfixed, the limiting end of the corresponding retaining band is pulled out from the retaining ring, so that the retaining needle head is unfixed.
In some embodiments, the longitudinal projected area of the bearing layer 120 on the adhesive layer 110 is smaller than the transverse cross-sectional area of the adhesive layer 110. That is, the lateral cross-sectional area of the adhesive layer 110 is larger than the lateral cross-sectional area of the supporting layer 120, for example, the lateral cross-sectional area of the adhesive layer 110 is 1.5 times that of the supporting layer 120, so that the adhesive layer 110 can repeatedly cover the supporting layer 120, and the adhesive effect of the fixing patch for the indwelling needle joint of the present application is improved.
In some embodiments, one end of the carrier layer 120 is flush with the end surface of the adhesive layer 110. Specifically, the retaining needle connector fixing patch of the present application may be rectangular, that is, the supporting layer 120 and the adhesive layer 110 may be flush on one side, so as to effectively reduce the influence of the adhesive layer 110 on the retaining needle connector during use, for example, to avoid the adhesive layer 110 from adhering to the retaining needle connector. In some embodiments, the adhesive layer 110 may wrap around the supporting layer 120 and have one end flush, so that the adhesive effect of the fixing patch of the indwelling needle connector can be ensured, and the influence of the adhesive layer 110 on the use of the indwelling needle connector can be reduced.
In other embodiments, the support layer 120 is provided with an anti-pressing protrusion 121 extending away from the adhesive layer 110, and the anti-pressing protrusion 121 is located at an end of the support layer 120 flush with the end surface of the adhesive layer 110. It can be understood that the end of the supporting layer 120 flush with the end surface of the adhesive layer 110 can correspond to the head of the remaining needle connector (i.e. the end of the remaining needle connector used for connecting an external infusion apparatus or other devices), namely, when the remaining needle connector is fixed on the remaining needle connector, the head of the remaining needle connector is placed towards the end of the supporting layer 120 flush with the end surface of the adhesive layer 110, and the remaining needle connector can be further effectively isolated from being in direct contact with a human body by utilizing the anti-pressing protrusions 121, so that the remaining needle connector can effectively press the human body for a long time to generate pressure sores, and the comfort of the patient is further ensured.
In some embodiments, the inner side of the fixation strap 130 is provided with a lubricious layer 133. Wherein the lubricious layer 133 is primarily used to reduce friction against the catheter adapter, thereby allowing space for the catheter adapter. It can be appreciated that during the use of the indwelling needle, the patient may inevitably need to move, and if the indwelling needle connector cannot move in a certain space, the infusion tube which is easily communicated with the indwelling needle connector is folded in half, so that the infusion effect is affected. When the indwelling needle connector is fixed, the fixing belt 130 is abutted to the surface of the indwelling needle connector through the smooth layer 133, so that the indwelling needle connector can deviate in a certain range to form a certain buffer space, and when a patient moves, the indwelling needle connector can slightly deviate along with shaking of the infusion tube by utilizing the buffer space, so that the safety during infusion is effectively improved. It should be noted that the indwelling needle hub may be slightly offset from left to right and cannot be pulled out from between the anchoring band 130 and the buttress layer 120. In some embodiments, the contact area of the lubricious layer 133 with the needle hub may be slightly smaller than the projected area of the needle hub on the fixation band 130.
In some embodiments, the indwelling needle connector fixing patch may comprise two sets of fixing bands 130 and fixing rings 140, and the two sets of fixing bands 130 and fixing rings 140 are arranged along the indwelling needle connector placement direction. Specifically, the two sets of fixing straps 130 and the fixing ring 140 can be used for fixing the head and the tail of the remaining needle connector respectively, so that the fixing effect on the remaining needle connector can be effectively improved, and the falling off of the remaining needle head caused by shaking of the remaining needle connector is further prevented. The smooth layer 133 may be provided with only the fixing band 130 for fixing the head of the indwelling needle connector, so that the indwelling needle connector is further prevented from being pulled out from between the fixing band 130 and the supporting layer 120, and the fixing effect of the indwelling needle connector fixing patch of the present application on the indwelling needle connector is ensured.
In some embodiments, the indwelling needle hub fixation patch may further include a positive stop 150 disposed on a surface of the supportive layer 120. Specifically, the limit stop 150 is located on the same side of at least one set of the fixing band 130 and the fixing ring 140, and the limit stop 150 is mainly used for limiting and fixing the bottom of the remaining needle connector, so that the quick positioning when the remaining needle connector is fixed on the supporting layer 120 can be realized by using the limit stop 150, the convenience of the remaining needle connector fixing patch in use is improved, and the fixing effect on the remaining needle connector is further improved. In some specific embodiments, the bump stop 150 is provided with a bump sidewall 151 for abutting against the bottom of the indwelling needle hub, wherein the bump sidewall 151 is flared. Specifically, the caliber of the limiting side wall 151 gradually increases from the bottom of the retaining needle connector to the head along the retaining needle connector placement direction. The bottom of the retaining needle connector is abutted by the limiting side wall 151, so that retaining needle connectors with different specifications can be adapted, and the fixing requirement of the retaining needle connector fixing paste provided by the application on retaining needle connectors with different specifications is met. In some embodiments, the positive stop 150 may be comprised of two sub-stops that are axisymmetrically distributed. Wherein, the side wall that is used for the butt to keep somewhere the needle joint is provided with each other to two sub-dogs, and the side wall of two sub-dogs forms spacing lateral wall 151.
Fig. 4 is another schematic structural view of an indwelling needle connector fixing patch according to an embodiment of the present application.
Referring also to fig. 4, in some embodiments, the indwelling needle hub fixation patch may further include a reinforcing layer 160 disposed on the adhesive layer 110. Wherein the reinforcing layer 160 winds around the supporting layer 120, forms a spacing space 170 between the reinforcing layer 160 and the adhesive layer 110, and the edge of the supporting layer 120 is provided with a spacing convex edge 122, and the spacing convex edge 122 is arranged in the spacing space 170, and the spacing effect of the spacing convex edge 122 by utilizing the spacing space 170 is realized to reinforce the supporting layer 120, enhance the fixing effect of the supporting layer 120 on the fixing patch of the remaining needle connector, and further improve the reliability of the integral structure of the fixing patch of the remaining needle connector. In some embodiments, the reinforcing layer 160 is integrally formed with the adhesive layer 110. Specifically, the reinforcing layer 160 and the adhesive layer 110 may be made of the same material.
In the embodiment, the technical scheme of the application can be directly adhered to the surface of a human body through the adhesive layer, and the detachable fixing structure is formed by utilizing at least one group of fixing belts and fixing rings on the supporting layer, so that the detachable fixing of the indwelling needle connector is realized, the loosening of the needle head of the indwelling needle caused by the shaking of the indwelling needle connector is effectively reduced, the stability of the indwelling needle in use is improved, and meanwhile, in the mode of detachable fixing, the indwelling needle connector is more convenient in use by releasing the fixing of the indwelling needle connector when transfusion or blood collection operation is needed.
