The self-purging transfusion device of a kind of noresidue liquid drips the kettle assemblyTechnical field
This utility model relates to a kind of transfusion device and drips the kettle assembly, is specially the self-purging transfusion device of a kind of noresidue liquid and drips the kettle assembly, belongs to technical field of medical instruments.
Background technology
Transfusion device is one of hospital's medical apparatus and instruments commonly used, is mainly used in the gravity type venous transfusion.Generally be to be connected to form by intravenous needle, helmet, infusion tube, liquid medicine filter, flow regulator, a kettle assembly, bottle plug puncture unit, air inlet pipe air filter.Under atmospheric effect, the liquid runs down infusion tube flows into and drips kettle in the bottle, and when dripping the kettle water column pressure greater than venous pressure, the liquid runs down flexible pipe in the bottle flows into passages through which vital energy circulates.
Drip the kettle assembly and generally comprise a kettle and be covered in a kettle seal cover suitable for reading, be provided with a minim pipette on the seal cover and be communicated with the in-and-out system that drips kettle; Minim pipette is communicated with infusion bottle by infusion tube, bottle plug puncture unit in the part in the seal cover outside; Drip the kettle bottom and be divided into funnelform dropping funnel, its bottom is catheter, and catheter is communicated with the passages through which vital energy circulates of human body by infusion tube, passages through which vital energy circulates pin in the part of dropping funnel outside.The sidewall of the upper semisection of the part of catheter in dropping funnel has inlet, and the medicinal liquid in the dropping funnel is able to enter by inlet the hollow space of catheter.
There are some defectives in this kettle assembly: 1, because catheter is high than the dropping funnel bottom in the lower end of inlet, therefore, medicinal liquid has residual in dropping funnel; 2, a traditional kettle drips and weighs not, causes dropping liquid slower, is difficult for regulating.
The utility model content
The purpose of this utility model is in order to provide the self-purging transfusion device of a kind of noresidue liquid to drip the kettle assembly, to solve existing the problems referred to above of dripping kettle.
The purpose of this utility model can be achieved through the following technical solutions:
The self-purging transfusion device of a kind of noresidue liquid drips the kettle assembly, comprises dripping kettle, and kettle seal cover suitable for reading is dripped in sealing, runs through the minim pipette that seal cover is communicated with a kettle, and minim pipette is connected with infusion tube in the part of seal cover outside; Also comprise being plugged in and drip the catheter that the kettle bottom is communicated with a kettle and infusion tube, it is inlet that the partial sidewall of described catheter in dripping kettle is provided with some vertically evenly distributed finedraws; The lower end of described inlet is concordant with the inwall that drips the kettle bottom.
Install for convenient, be provided with adapter sleeve between catheter and a kettle, the upper surface of described adapter sleeve flushes with the inlet lower end.
Drip the heavy deficiency of dripping of kettle in order to solve, the excessively slow problem of the lower speed of medicinal liquid is provided with an air filter with air film at the sidewall that drips kettle.
In order to guarantee the health of air film, also dispose safety head at air filter, open during use.
Bonding by viscose between described seal cover and the kettle.
The transfusion device that forms by this utility model setting drips the kettle assembly, and delicate structure can be after using end, and without liquor residue, neither waste also brings convenience for the post-processed of transfusion device in the kettle.And the setting of air filter both can solve and drip the heavy problem of kettle Chinese medicine drop, can prevent that again airborne micronic dust from entering a kettle.The design of finedraw on the catheter sidewall can reach from exhaust effect, need not when the nurse infuses to be inverted or the extruding dropping funnel makes that liquid is smooth and easy to be flowed down.
Description of drawings
Fig. 1 is the structural representation that this utility model drips the kettle assembly;
Among the figure: 1, drip kettle 2, seal cover 3, minim pipette 4, catheter 5, inlet 6, air filter 7, adapter sleeve.
The specific embodiment
Further set forth construction features of the present utility model below in conjunction with accompanying drawing and specific embodiment.
The self-purging transfusion device of a kind of noresidue liquid as shown in Figure 1 drips the kettle assembly, comprises dripping a kettle 1, and kettle 1 seal cover 2 suitable for reading is dripped in sealing, runs through the minim pipette 3 that seal cover 2 is communicated with a kettle 1, and minim pipette 3 is connected with infusion tube in the part of seal cover 2 outsides; Also comprise being plugged in and drip the catheter 4 that kettle 1 bottom is communicated with a kettle 1 and infusion tube, it is inlet 5 that the partial sidewall of described catheter 4 in dripping kettle 1 is provided with some vertically evenly distributed finedraws; The lower end of described inlet 5 is concordant with the inwall that drips kettle 1 bottom.
Install for convenient, be provided with adapter sleeve 7 between catheter 4 and a kettle 1, the upper surface of described adapter sleeve 7 flushes with inlet 5 lower ends.
Drip the heavy deficiency of dripping of kettle in order to solve, the excessively slow problem of the lower speed of medicinal liquid is provided with an air filter 6 with air film at the sidewall that drips kettle 1.
In order to guarantee the health of air film, also dispose safety head at air filter 6, open during use.
Bonding by viscose between described seal cover 2 and the kettle 1.
