Stop in the concrete size of liquid device at described automatic vent:
In the concrete structure of described upper shell 1: the housing outer diameter of described upper shell 1 is 19.4mm, the external diameter of the liquid inlet joint pipe at described upper shell 1 top is 5mm;
In the concrete structure of described intermediate 2: the housing outer diameter of described intermediate 2 is 21.3mm, the internal diameter of described first conduit is 3.5mm; The internal diameter of described second conduit is 2mm; The duct height of described first conduit is 1.5mm; The duct height of described second conduit is 5.1mm;
In the concrete structure of described lower house 3: the housing outer diameter of described lower house 3 is 19.4mm, the external diameter of the fluid junction block of the bottom of described lower house 3 is 5.9mm.
It should be noted that, outside dimension between described upper shell 1, described intermediate 2 and described lower house 3 adapts to mutually, can ensure that three can be formed like this and effectively embed connection (namely the size configurations of above-mentioned three's structure can ensure that the formation of upper shell 1, intermediate 2 and lower house 3 closely cooperates) closely.
Preferably, can embodiment as one; As shown in Figure 5, the outer wall of the top shell of described upper shell 1 arranges stop bosses 12; As shown in figure 11, the outer wall of the bottom shell of described lower house 3 also arranges stop bosses 12; Described spacing preiection portion 12 is for limiting described intermediate 2 respectively relative to the mutual interlocking height and position of described upper shell 1 and described lower house 3.
It should be noted that, described upper shell 1, described intermediate 2 and described lower house 3 three formed mutually interlocking fixing after, the spacing preiection portion 12 on the outer wall of upper shell 1 can ensure that intermediate 2 can not be plugged excessive, locks its its rabbet position; Equally, the outer wall upper limit lobe of lower house 3 also can play similar effect, repeats no longer one by one this.
It should be noted that, in this utility model embodiment, above-mentioned single use precision filter infusion set, wherein its upper shell, intermediate, lower house can adopt medical high-environmental plastic construction, and its material is through being usually used in the high place of this sanitary grade such as hospital, medical treatment, scientific research institution; This silica gel sealing ring resilience is strong, and good airproof performance, life-time service does not turn yellow colour-fast, does not affect result of use.Meanwhile, above-mentioned medical high-environmental plastics also have technical performance superior as follows: 1, sanitary grade is high, environmental protection, efficiently tasteless; 2, hot strength is high, high tear, low-shrinkage, and resilience is good; 4. long-time use also can not be out of shape, and resistance to biodeterioration can wait feature by force.
Introduce concrete service condition and the function of single use precision filter infusion set below:
1, automatically removing air in whole infusion process.This technology point reaches this effect by this device, and transfusion device does not at ordinary times have this device, needs manually to go to reach exhaust apparatus.And this device is exactly automatic vent, do not need artificially manually to go aerofluxus.
2, automatic liquid-stopping: (when in whole infusion process.When liquid medicine will be totally lost.Can be reached by the physical arrangement of this device and automatically stop liquid medicine input.Out of question time again in half an hour.Give when not being able to do in time process and race against time.)。
3, automatically blood backflow is prevented: (after liquid medicine is totally lost, this modifying device is also to prevent blood backflow, causes human injury.What reach this effect is also this device.
This product adopts physics to stop liquid and blood return prevention function, automatic ventilating function, prevents transfusion from dripping empty.When stopping liquid status, dropping funnel lower end Unique physical design, can prevent backflow of blood, avoids blood back phenomenon.Repeatedly can get rid of excessive gas in changing bottle of infusion process, and automatically descend liquid.
[description of product]
1, when medicinal liquid be totally lost change medicinal liquid bottle (bag) time, automatically can close infusion channel, stop air to enter patient's vein, changing after single only liquid cannot the shortcoming of blood return prevention.
2, in infusion process, need not transfusion condition be paid close attention to, only after liquid, have the function of blood return prevention.
3, facilitate liquid medicine flow owing to arranging automatic ventilating function, without the need to extruding dropping funnel, liquid can flow into dropping funnel automatically, automatically controls the normal level of liquid in dropping funnel; Due to automatic vent, excessive gas in dropping funnel is got rid of, can not bubble be produced in a liquid, guarantee safe infusion, improve medical worker's work efficiency;
The operation principle of precision liquid medicine filter membrane: medicinal liquid flows in dropping funnel, flow through precision liquid medicine filter membrane, medicinal liquid is filtered fully, the rejection rate that precision liquid medicine filter membrane is 5 ± 1 μm of microgranules for diameter in medicinal liquid is not less than 90%, when the medicinal liquid of infusion bottle is totally lost complete, medicinal liquid liquid level in dropping funnel declines gradually, when the liquid level of medicinal liquid drops to the position of precision liquid medicine filter membrane, aperture because of precision liquid medicine filter membrane tiny and liquid separatnig plate height two conduits and air negative pressure principle, air can be stoped to pass through precision liquid medicine filter membrane, make that the medicinal liquid in transfusion device long tube is static no longer flows into intravenous, thus can prevent air from entering in infusion pipeline, can effectively prevent blood backflow and air from entering in patient body simultaneously, reach the object of automatic liquid-stopping and secondary filter.
The operation principle of automatic exhaust device: in the process that transfusion operation starts, discharges the gas in dropping funnel automatically, and it effectively can prevent the generation of bubble and prevent bubble from entering in transfusion long duct, and the process that transfusion aerofluxus is steeped is not only easy but also quick.It should be noted that; Effective aerofluxus significantly decreases the waste of medicinal liquid and effectively prevent the pollution caused syringe needle, effectively ensure that patient is in the maximum curative effect of medication carried out in the process for the treatment of and the generation decreasing nosocomial infection, achieves very good clinical benefit.
In sum, the single use precision filter infusion set that this utility model embodiment provides, has and prevents blood backflow and bubble from entering human body and self-bleeding function; It is very easy to use, and the design of its structure function is improved and rationally, be also ensure that the safety and reliability of medical and health conditions and venous transfusion simultaneously.Therefore, the single use precision filter infusion set that this utility model embodiment provides will bring good market prospect and economic benefit.
Last it is noted that above each embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristic; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of this utility model.
