Abstract

A three-channel adjustable filter type infusion apparatus belongs to a medical appliance and is used for clinical infusion treatment. It is characterized in that the side wall tube cavity composed of a cavity, a cap and a three-way tube is additionally arranged at the position 4-12cm above the nipple between a regulating valve and a filter of a well-known transfusion device consisting of a bottle inserting needle head, an exhaust pipe, a Murphy's dropper, a transfusion tube, a regulating valve, a filter and the nipple. Has the advantages of reasonable structure, low cost, simple and standard operation, sterile operation, pain reduction for patients, work efficiency improvement, contribution to rescue, three-channel adjustable filtration type venous transfusion treatment by being connected with an injector or another set of transfusion device, and the like.

Description

Triple channel scalable filtering type transfusion device

A kind of triple channel scalable filtering type transfusion device belongs to technical field of medical instruments, is mainly used in the clinical transfusion treatment.

In prior art,, often adopt the venous indwelling syringe needle to carry out venipuncture clinically to reach desired therapeutic effect for operation, critical and patient that venipuncture is difficult.Though this operational approach has the advantages such as time length that can reduce venipuncture number of times, syringe needle indwelling, but owing to still do not have supporting with it transfusion device in the prior art, make the aforesaid operations method have following drawback: one, when carrying out intravenous injection, because of the venous indwelling syringe needle terminal near excessively apart from venipuncture point with transfusion device nipple junction, when separating the junction point of the two, easily cause venous blood to reflux in a large number, fast, make venipuncture point be subjected to blood contamination, and the medicinal liquid that injects does not meet sterile working's requirement not through filtering; Two, at no incompatibility, need two-way liquid simultaneously under the situation of venous transfusion, because of the tee T volume is big, be difficult for fixingly, clinical practice inconvenience needs venipuncture separately, not only operates cumbersomely can incur loss through delay rescue opportunity, but also has increased patient's misery; Three, all need clean venipuncture point and change aseptic dressing owing to whenever doing an intravenous injection, thereby cause the waste of manpower and materials.

The purpose of this utility model be to provide a kind of rational in infrastructure, cost is low, standard easy and simple to handle, can guarantee the sterile working, reduce patient's misery, improve nursery work efficient, guarantee timely rescue, be convenient to the triple channel scalable filtering type transfusion device of clinical transfusion treatment.

Can flow and normal person's central venous pressure is 4 to 12cm these basic fact of water column to same tube chamber simultaneously through two passes according to liquid under certain condition, at the subject matter that exists in the prior art, basic design of the present utility model is: set up one by cavity cap at the above 4-12cm of nipple place between the control valve of existing transfusion device and filter, the sidewall tube chamber that cavity and tee T are formed, the control valve that both can prevent to have closed not busy and sidewall tube chamber gas under open situation enter vein through this tube chamber and form aeroembolism, can link to each other with syringe by this open sidewall tube chamber according to state of an illness needs again, carry out intravenous injection, thereby avoid repeated multiple times separate to keep somewhere syringe needle terminal with being connected of transfusion device nipple, also can connect another set of transfusion device again and carry out triple channel scalable filtering type venous transfusion and treat.

Of the present utility modelly be characterised in that described triple channel scalable filtering type transfusion device, be between by above-mentioned control valve that is equipped with the known transfusion device that needle for inserting bottle head, exhaustor, Murphy type burette, tube for transfusion, control valve, filter and nipple form from top to bottom successively and filter and be positioned at the 4-12cm place that equates with normal person's central venous pressure value more than the above-mentioned nipple set up one by the cavity that is connected as a single entity with the tee T that is connected with integral body and be buckled in the sidewall tube chamber that the cavity cap on the cavity mouth is formed.

The utility model has the advantages that: simple in structure, rationally, overcome the existing shortcoming of existing like product, cost is low, be convenient to the clinical transfusion treatment, especially can realize the transfusion of triple channel scalable filtering type, both can according to state of an illness needs carry out intravenous injection avoid repeated multiple times separate to keep somewhere syringe needle terminal with being connected of transfusion device nipple, minimizing is to the pollution of venipuncture point, guarantee the sterile working, also can connect another set of transfusion device again and carry out the treatment of triple channel scalable filtering type venous transfusion, solved the technical barrier that indwelling syringe needle and tee T are difficult for being connected and fixed, avoid venipuncture repeatedly to cause suffering to patient and to the trouble that medical personnel bring, improved work efficiency, being beneficial to races against time rescues the critical patient, simultaneously can also save the man power and material, avoid waste.

Accompanying drawing is one of this utility model most preferred embodiment overall appearance structural representation.

1 needle for inserting bottle head among the figure, 2 exhaustors, 3 Murphy type burettes, 4 tube for transfusions, 6 control valves, 6 sidewall tube chambers, the 6a cavity cap, the 6b cavity, 6c connects tee T, 7 filters, 8 nipples.

In conjunction with the accompanying drawings and most preferred embodiment, architectural feature of the present utility model further is summarized as follows: needle for inserting bottle head 1 its lower end of duroplasts matter connect successively exhaustor 2 that the eliminating bubble of the flexible plastic matter perpendicular with it uses and with syringe needle 1 in the tubular axis line in line the wall thickness of up/down perforation be the Murphy type burette 3 of 0.4mm flexible plastic matter, tube for transfusion 4, control valve 5, spheric filter 7 and nipple 8, between above-mentioned control valve 5 and filter 7, nipple 8 above 8cm places have one by connecting tee T 6c and the cavity 6b that is connected as a single entity with it and can being buckled in the sidewall tube chamber 6 that cavity cap (being connected together by time band with the cavity) 6a on the cavity mouth forms.

Change as present embodiment:

1, the raw material of each member and overall dimensions can suitably change;

2, the sidewall tube chamber is provided with the position and can changes in nipple 8 above 4-12cm scopes;

3, the sidewall tube chamber both can be connected with syringe also and can be connected with another set of transfusion device, carried out triple channel scalable filtering type infusion treatment.
