Description

A medical infusion pressurizer

technical field

The utility model relates to a medical device, in particular to a medical transfusion pressurizer.

Background technique

Practice has proved that for the treatment of hemorrhagic shock, the most effective means is to immediately give a large amount of rapid rehydration on the basis of ensuring the smooth airway and effective hemostasis, so rapid blood injection has always been one of the problems that people want to solve . When hospital medical personnel are rescuing patients, especially for some patients with excessive blood loss, they often need rapid infusion of liquid medicine. At present, during blood transfusion, doctors or nurses generally pressurize the infusion bag by hand to inject blood into the human body, but manual pressurization often causes insufficient or uneven pressure, which affects the rescue of critically ill patients in severe cases.

Contents of the invention

The purpose of the utility model is to solve the above problems and provide a medical transfusion pressurizer with simple structure, automatic pressure control and uniform pressure.

The technical solution adopted by the utility model to solve the problems of the technologies described above is:

It includes an airtight casing, one side of the casing is provided with a blood bag placement opening, the bottom of the casing cavity is provided with an elastic body, and the elastic body is provided with an extruded air bag, on which the blood bag is placed, and on the extruded air bag An air intake duct is provided, a valve is arranged on the air intake duct, and the end of the air intake duct is connected with an extruded air bag.

The above extruded airbag includes a lower force application plate, the lower force application plate is provided with an extrudable airbag cavity, and the upper part of the airbag cavity is provided with an upper force application plate.

The elastic body is provided with a guide rod shorter than the elastic body.

The above-mentioned elastic bodies are springs, and two are arranged symmetrically on the bottom surface of the housing.

Compared with the prior art, the utility model has achieved the following technical effects:

1. The structure of this utility model is simple, the pressure is automatically controlled, and the pressure is uniform;

2. By setting the extruded airbag so that the upper and lower sides are plates, and the middle is an extrudable airbag cavity, it is easy to compress and also ensures the support up and down;

3. By setting a guide rod shorter than the elastic body in the elastic body, it is convenient for the vertical establishment of the elastic body, and it is not easy to tilt;

4. By arranging two springs symmetrically, the stability of the spring support can be further improved.

Description of drawings

Fig. 1 is a schematic diagram of the appearance of the utility model;

FIG. 2 is a partial cross-sectional view of FIG. 1 .

Among them: 1-blood bag placement port, 2-upper force plate, 3-squeezable airbag cavity, 4-lower force plate, 5-elastomer, 6-intake duct, 7-valve, 8-squeeze Pressure inflation bag, 9-housing, 10-guide rod.

Detailed ways

Further illustrate the embodiment of the present utility model below in conjunction with accompanying drawing.

Example 1

Referring to Fig. 1-2, a medical infusion pressurizer includes a closed casing 9, a blood bag placement port 1 is provided on one side of the casing, and two elastic bodies 5 are symmetrically arranged at the bottom of the inner cavity of the casing. , the number of elastic bodies here can also be four, and the elastic bodies can be springs. A guide rod 10 shorter than the elastic body is provided inside the elastic body, and an extruded air bag is arranged on the elastic body, and the extruded air bag includes a lower force applying plate 4, and an extrudable air bag cavity 3 is arranged on the lower force applying plate , The upper portion of the airbag cavity is provided with an upper force application plate 2 . A blood bag is placed on the upper force-applying plate, an air intake duct 6 is arranged on the air bag cavity of the extruded air bag, a valve 7 is arranged on the air intake duct, and an extruded air bag 8 is connected to the end of the air intake duct.

The working process of the utility model is as follows: when in use, place the blood bag from the blood bag placement port 1 on the upper force plate 2 of the extruded air bag, open the valve 7 on the air intake duct 6 by hand, and squeeze the air bag by hand. Press and inflate the air bag 8, and air flows into the extruded air bag from the air intake duct 6. Because the inner height of the housing 9 is constant, and the inner inflation of the extrusion airbag pushes the upper force application plate 2 of the extrusion airbag to move upward, the blood bag will give the same reaction force to the upper force application plate 2 of the extrusion airbag, forcing the spring to apply The force plate 4 moves downward, so that the spring on the lower end guide rod 10 is compressed. The pressure is converted into elastic potential energy storage, which is released gradually. The utility model is simple and convenient to operate, and can quickly infuse the patient to treat the patient to the greatest extent.

The scope of protection of the utility model is not limited to the above-mentioned embodiments. Obviously, those skilled in the art can make various changes and deformations to the utility model without departing from the scope and spirit of the utility model. If these changes and deformations fall within the scope of the claims of the utility model and their equivalent technologies, the intent of the utility model is to include these changes and deformations.
