AI Technical Summary
Most existing blood transfusion pressure bags use manual pressurization, which increases the workload of medical staff and may lead to interruption of the blood transfusion process or loss of pressure due to improper operation.
A blood transfusion pressure bag was designed, which includes a placement mechanism and a pressure mechanism. Automatic pressure is achieved by using a counterweight box and a thrust spring. Gravity causes the squeezing roller to move from top to bottom to continuously pressurize the blood transfusion bag, reducing manual operation.
It has enabled an automated blood transfusion pressurization process, reducing the workload of medical staff, avoiding interruptions or pressure loss during the transfusion process, and improving the convenience and safety of blood transfusion operations.

[0002] Blood transfusion, as an indispensable part of clinical treatment, plays a vital role in rescuing critical patients, supplementing blood volume, improving circulation and increasing oxygen carrying capacity. During blood transfusion, especially in emergency rescue, in order to ensure that the blood can be smoothly and quickly delivered to the patient's body, a blood transfusion pressure bag is usually used to pressurize the blood transfusion bag to overcome the resistance in the blood transfusion pipeline and improve the blood transfusion speed. As a key equipment in the blood transfusion system, the design and performance of the blood transfusion pressure bag directly affect the safety and efficiency of blood transfusion.
[0003] However, the current blood transfusion pressure bag adopts a manual pressure mode, which pressurizes the blood transfusion bag by manually squeezing the inflatable air bag by medical staff. Although this mode meets the clinical requirements to some extent, it requires medical staff to continuously squeeze the inflatable air bag, which not only increases the work burden of medical staff, but also may lead to interruption of the blood transfusion process or pressure out of control due to improper operation, thereby reducing the use effect. Therefore, the applicant proposes a blood transfusion pressure bag to solve the above problems. UTILITARY MODEL CONTENTS

[0028] Example 1:
[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a blood transfusion pressure bag includes:
[0030] Placement mechanism 1 and pressurization mechanism 2 assembled on placement mechanism 1;
[0031] The placement mechanism 1 includes a placement bag 13, a fixing frame 11 is fixedly installed on the top of the placement bag 13, and a fixing seat 15 is connected to the bottom of the placement bag 13;
[0032] The pressurizing mechanism 2 includes a movable ring 21 that is slidably installed around the bag 13. A counterweight box 22 is fixedly installed on both sides of the movable ring 21. A movable arm 23 is hinged to the bottom of the movable ring 21. A squeezing roller 28 is rotatably installed between the movable arms 23. The squeezing roller 28 is in contact with both sides of the bag 13. A thrust spring 210 is connected between the movable arm 23 and the movable ring 21.
[0033] As can be seen from the above, when in use, by pressing the operating lever 25 upward, the operating lever 25 and the moving ring 21 are closed, which can easily drive the movable arm 23 to flip upward, which can drive the squeezing roller 28 to flip outward, so that the squeezing roller 28 can be separated from the placement bag 13. The blood transfusion bag can be easily placed into the placement bag 13 through the opening on the fixed frame 11. The placement bag 13 is used by suspending it in a suitable position. After the blood transfusion bag is placed into the placement bag 13, by releasing the operating lever 25, the pushing force applied to the movable arm 23 by the push spring 210 can push the movable arm 23 to flip downward, so that the squeezing roller 28 can squeeze the two sides of the placement bag 13, which can facilitate the pressure operation of the blood transfusion bag.
[0034] By placing a counterweight in the counterweight box 22, gravity can be used to move the moving ring 21 downwards, which in turn pushes the squeezing roller 28 to roll downwards along both sides of the placement bag 13. This allows for continuous and automatic squeezing of the blood transfusion bag from top to bottom. By changing the weight of the counterweight in the counterweight box 22, the squeezing speed can be easily adjusted according to the transfusion requirements. There is no need to manually press the inflation bag for inflation and pressurization, which effectively reduces the workload of medical staff and avoids interruptions or pressure loss during the transfusion process due to improper manual operation, bringing more convenience to the transfusion operation.
[0035] Depend on Figure 2 and Figure 3 It can be seen that the top of the fixed frame 11 is fixedly installed with symmetrically arranged hanging straps 12, and the bottom of the fixed base 15 is provided with a through hole 16 that communicates with the bag 13.
[0036] As can be seen from the above, the placement bag 13 can be easily suspended in a suitable position by the suspension strap 12, and the catheter at the bottom of the blood transfusion bag can be extended through the through hole 16 without affecting the blood transfusion operation for the patient.
[0037] For details, please refer to Figure 1 , Figure 3 and Figure 4 As shown, a slide rod 14 is fixedly installed between the fixed frame 11 and the fixed base 15, and the slide rod 14 passes through the moving ring 21.
[0038] As can be seen from the above, the sliding rod 14 can conveniently limit the movement of the moving ring 21, so that the moving ring 21 will not be tilted when it moves up and down, which can improve the uniformity of the compression of the bag 13.
[0039] For details, please refer to Figure 4 As shown, the movable ring 21 has a sliding hole 211 for the sliding rod 14 to slide, and the movable ring 21 and the movable arm 23 are hinged together by the movable seat 212.
[0040] As can be seen from the above, the sliding ring 21 can slide up and down along the slide bar 14 through the sliding hole 211, and the movable arm 23 can be flipped by the movable seat 212.
[0041] Example 2:
[0042] refer to Figure 4 As shown, anti-slip strips 29 are adhered to the surface of the extrusion roller 28, and the anti-slip strips 29 are distributed in a ring array at equal intervals.
[0043] As can be seen from the above, the anti-slip strip 29 can increase the friction between the extrusion roller 28 and the placement bag 13, making it less likely for the extrusion roller 28 to slip when it rolls and extrudes the placement bag 13.
[0044] refer to Figure 4 and Figure 5 As shown, an operating lever 25 is slidably mounted on the front end of the movable arm 23, and a pressing seat 26 is fixedly mounted on the front end of the operating lever 25 and the front end of the moving ring 21.
[0045] As can be seen from the above, by pinching and pressing the seat 26, the operating rod 25 and the moving ring 21 can be easily driven to close together, and the squeezing roller 28 can be easily operated to expand outward.
[0046] refer to Figure 5 As shown, the movable arm 23 and the operating rod 25 are slidably installed together via a sliding post 24, and the operating rod 25 is provided with a sliding groove 27 for the sliding post 24 to slide.
[0047] As can be seen from the above, the sliding block 24 is limited by the sliding groove 27, which allows the sliding block 24 to slide along the sliding groove 27. When the operating rod 25 moves up and down, it can drive the movable arm 23 to perform up and down flipping motion.
[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
