Description

A kind of transfusion device of conveniently injecting medicine

Technical field

This utility model relates to a kind of transfusion device, and this transfusion device can be injected medicine easily in the process of transfusion, belong to medical instruments field.

Background technology

Transfusion is the very common treatment means of hospital and clinic.In infusion process,, may also need additionally to inject other medicines according to the needs of the state of an illness.Injecting of these medicines also undertaken by transfusion device.Existing transfusion device structure is connected withsyringe needle 2 at infusion tube 1 one ends as shown in Figure 1, and the other end is provided with thejoint 3 that is connected with infusion bottle or transfusion flexible bag.What also be provided with speed adjustinggear 4,gauge tap 5, black Fei Shipipe 6 on the infusion tube 1 and conveniently push away the acupuncture treatment head is affectedly bashful part 14.In order to inject medicine, infusion tube 1 constitutes by two sections that can unplug, and when not injecting medicine, two sections are docking together.Inject medicine if desired, again two sections are unpluged, medicine is injected in following that section flexible pipe.Because the medicine of injecting is often measured less, need enter human body fast and do not mix with other drug, so the flexible pipe disconnected position is often near syringe needle as far as possible.

The said structure setting of transfusion device, when medicine is injected, have the following disadvantages: 1, two of infusion tube sections separately after, two sections joint area all is exposed in the air, has the risk of polluting, this is very disadvantageous to patient, more wants strictness to avoid contacting with object on every side; 2, cause blood to reflux in order to prevent below the air admission in that section flexible pipe, when injecting medicine, the nurse can be stuck with following flexible pipe, and is not only inconvenient, also lack of standardization; 3, in injecting the medicine process, above that section flexible pipe still can dropping liquid, have waste; 4, nurse's professional skill is required height, require action consummate, otherwise can not finish this work well.

The utility model content

At the prior art above shortcomings, the purpose of this utility model provides a kind of convenient, safe transfusion device of medicine of injecting.

The technical solution of the utility model is achieved in that a kind of transfusion device of conveniently injecting medicine, and it comprises infusion tube, is provided with speed adjusting gear on infusion tube, conveniently pushes away the part of being affectedly bashful of acupuncture treatment head, and infusion tube is made of two sections; The epimere infusion tube is connected with hypomere infusion tube wherein two terminals by three-way valve, and the three-way valve terminal that is connected with the epimere infusion tube is provided with control valve; The 3rd terminal of three-way valve injected the medicine dedicated terminals and is provided with control valve for injecting the medicine dedicated terminals, injects medicine dedicated terminals port and is provided with dust cap.

Further, described injecting in the medicine dedicated terminals port is provided with rubber plunger, and dust cap covers rubber plunger.

Described being affectedly bashful is preset with adhesive plaster on the part.

Described speed adjusting gear is provided with the scale that speed is dripped in reflection.

This utility model is owing to be provided with three-way valve injecting the medicine position, and three-way valve wherein two terminals connects the two sections infusion tube, and another terminal is exclusively used in injects medicine.During normal infusion, the two sections flexible pipe is connected, and injects the terminal of medicine and closes; When needs are injected medicine, disconnect the two sections flexible pipe, open the terminal of injecting medicine and can directly inject medicine.

Compared to existing technology, the utlity model has following advantage:

1. the infusion tube two sections link together all the time by three-way valve, need not separate, and have avoided being exposed to the risk of being polluted in the air.

2. simple, convenient, less demanding to the nurse, and safety obtains very big enhancing, does not worry in the air admission infusion tube.

3. in injecting the medicine process, above that section flexible pipe outside dropping liquid not, stopped waste.

4. be affectedly bashful on the part directly fixedly adhesive plaster of band, handled easily is raised the efficiency, and reduces cost.

5. speed adjusting gear is provided with scale, the corresponding corresponding number of infusion drops of different scales, but accuracy controlling transfusion speed, and it is too fast or slow excessively to avoid infusing, and makes things convenient for medical personnel to control transfusion speed according to state of an illness needs.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Referring to Fig. 2, as can be seen, this utility model is conveniently injected the transfusion device of medicine from the figure, and what be provided with speed adjustinggear 4 and conveniently push away the acupuncture treatment head on infusion tube is affectedlybashful part 14, and infusion tube 1 is made of two sections equally.Its difference is: this utility modelepimere infusion tube 7 is connected withhypomere infusion tube 8 wherein two terminals by three-way valve 9, and the three-way valve terminal that is connected with the epimere infusion tube is provided with control valve 10.The 3rd terminal of three-way valve injected and also is provided withcontrol valve 10 on the medicine dedicated terminals 11 for injecting medicine dedicated terminals 11, injects medicine dedicated terminals 11 ports and is provided with dust cap 12, is used for and air insulated, avoids polluting.

In order to ensure the safety of injecting medicine, further, in injecting medicine dedicated terminals 11 ports, be provided withrubber plunger 13, dust cap 12 coversrubber plunger 13.

Described being affectedly bashful is preset with at least oneadhesive plaster 15 on the part 14.After syringe needle puncture puts in place, open the protective layer on the adhesive plaster, can be by adhesive plaster with syringe needle be affectedly bashful part and fix, handled easily has been avoided interim preparation adhesive plaster, and process is more calm, has improved efficient, has reduced cost.

Simultaneously, this utility model is provided with the scale 16 that speed is dripped in reflection on speed adjusting gear 4.The corresponding corresponding number of infusion drops of different scales, but accuracy controlling transfusion speed, it is too fast or slow excessively to avoid infusing, and makes things convenient for medical personnel to control transfusion speed according to state of an illness needs.

This utility model using method: during normal infusion, by with three-way valve terminal that the epimere infusion tube is connected on control valve the two sections flexible pipe is connected, close the terminal of injecting medicine simultaneously; When needs are injected medicine, disconnect the two sections flexible pipe by control valve, open the control valve of injecting on the medicine dedicated terminals simultaneously, take off dust cap, with dipping in spirituous cotton balls rubber plunger is sterilized, make syringe needle pass rubber plunger at last, can inject medicine.
