Abstract

The utility model relates to a quick blood infusion device. A pressurizing device communicated with a three-way pipe is arranged at the lower part of the three-way pipe, a pressure measuring device and an air sac with a mesh bag are arranged at the upper part of the three-way pipe, and the pressure measuring device and the air sac are communicated with the three-way pipe. After tested in clinic, the utility model can infuse 200 ml blood in 5 minutes, not only can be used for quickly infusing blood products of blood, blood plasma, etc., but also can be used for flushing the built-in artery pressure measuring pipe of heparin liquid, is safe in use, and can be widely popularized and used in clinic.

Description

Quick blood infusion device

This utility model belongs to medical attraction or pumping tool technical field, relates in particular to transfusion set.

At present blood, the blood plasma the like blood products that uses clinically is packed, owing to still there is not the special equipment of failing packed blood product at present, during blood transfusion, adopts the blood bag hung over more and utilizes potential energy on the drip stand, and it is flowed in the patient body lentamente.This transfusion set can not adapt to the needs that give emergency treatment to a patient when critical, sometimes for quick blood transfusion, have to the blood bag is improved, and increases potential energy, the speed of accelerating to transfuse blood.Perhaps medical personnel with the hands push the blood bag and increase the speed that the way of its internal pressure is accelerated to transfuse blood.Adopt this method, because power unbalanced power often of extruding, cause to such an extent that the speed of blood flow is sometimes fast and sometimes slow, the needs that incompatibility gives emergency treatment to a patient.

The purpose of this utility model is to overcome the shortcoming of above-mentioned transfusion set, and a kind of quick blood exchange transfusion set of isostasy is provided.

For achieving the above object, the solution that this utility model adopts is: be provided with the pressurizer that links with tee T in the bottom of tee T, be provided with the pressure device that links with tee T on the top of tee T and subsidiary mesh bag and and the air bag that links of tee T arranged.

Pressure device of the present utility model is a spring pressure ga(u)ge, and the piston of this spring pressure ga(u)ge is installed in the housing, and the words stopper rod is marked with scale, the resilient spring of outer cover, and an end and the piston of piston rod are connected as a single entity, and the other end stretches out outside the housing.

This utility model in use, do not need the blood bag is hung on the drip stand, can be placed on patient or bedside at one's side, through clinic trial, 200 milliliters of blood can be totally lost in 5 minutes, it is compared with the transfusion set that uses clinically, has advantages such as simple in structure, easy to carry, safe and reliable, that transfusion speed is fast.Its not only can be used for transfusing blood fast liquid, blood plasma the like blood products also can be used for containing the built-in tremulous pulse pressure-measuring pipe of heparin liquid wash.

Fig. 1 is the structure chart of this utility model most preferred embodiment.

Fig. 2 is the spring pressure ga(u)ge structure chart.

Fig. 3 is that the blood bag is placed on the sketch map between air bag and the mesh bag.

Just this utility model is further described below in conjunction with accompanying drawing and best enforcement.

In Fig. 1, Fig. 3, the intubate of tee T 8 bottoms and one inflate ball 10 and link, and the ball 10 of inflating is used to increase the pressure in the air bag 2.Inflating pneumatic control valve 9 of connection between ball 10 and the tee T 8.The intubate and the spring pressure ga(u)ge 7 of tee T 8 top left links, the right intubate links by trachea 6 and air bag 2.During blood transfusion, blood bag 3 can be placed between air bag 2 and the mesh bag 4, blood bag 3 links with blood transfusion tube 5, has one to be linked with 1 on the mesh bag 4, so that mesh bag 4 is hung on drip stand or other thing, also can be placed on patient to mesh bag 4 by the side of or bedside.

In Fig. 1, Fig. 2, a gim peg 7-2 is arranged in the outside of housing 7-1, so that spring pressure ga(u)ge 7 is fixed on the trachea 6, inside at housing 7-1, a piston 7-5 who is connected as a single entity with piston rod 7-4 is housed and is sleeved on the return spring 7-3 of piston rod 7-4 outside, the outer surface of piston rod 7-4 indicates scale, and the other end stretches out outside the housing 7-1.Variation along with housing 7-1 lower gas pressure, piston rod 7-4 can move up and down in housing 7-1, when the pressure of housing 7-1 lower gas increases, promoting piston 7-5 moves up, piston rod 7-4 stretches out calibrated data on the housing 7-1 part, promptly represents the barometric information in the air bag 2.When the pressure of housing 7-1 lower gas was normal pressure, return spring 7-3 was pushed into bottom in the housing 7-1 downwards with piston 7-5.

The quick blood transfusion of present embodiment is achieved in that the blood transfusion tube 5 that medical personnel will have injection needle earlier links with blood bag 3, and injection needle is penetrated in the patient's blood vessel, then blood bag 3 is put between air bag 2 and the mesh bag 4.At this moment, close pneumatic control valve 9, pinch repeatedly with hands and to inflate ball 10, the pressure of air constantly rises in the air bag 2, and the piston rod 7-4 of spring pressure ga(u)ge 7 stretches out outside the housing 7-1, and indicate the instantaneous pressure of air in the air bag 2, once the pressure of air bag 2 interior air is higher than the pressure of patient's blood vessel, transfusion speed is accelerated, when the pressure of air in the air bag 2 is 200 millimeter of mercuries, 200 milliliters of blood can be totally lost in 5 minutes, the highest 250 millimeter of mercuries that are defined as of pressure of air in the air bag 2.Open pneumatic control valve 9, the pressurized air in the air bag 2 will flow out from the gas outlet of pneumatic control valve 9, and the pressure of air is normal pressure in the air bag 2.

Pressurizer of the present utility model is inflated the ball 10 also pressurizer such as available electric air pump except that selecting for use.Pressure device of the present utility model also can select for use diaphragm capsule air gauge or other to survey pneumatic shuttle.
