TECHNICAL FIELD

[0001] The utility model relates to the field of medical auxiliary equipment especially, and relates to a relief device for plasma collection. BACKGROUND

[0002] In the field of medical and health management, blood collection is a routine and important operation, not only limited to plasma collection for blood transfusion or preparation of biological products, but also widely used in health detection, disease diagnosis, drug monitoring and other aspects. This process usually involves venipuncture, aiming to obtain blood samples for analysis to assess the health status of individuals or monitor the treatment effect. In order to alleviate the discomfort during blood drawing and ensure the smooth progress of sample collection, it is particularly important to take effective auxiliary measures.

[0003] In actual operation, some individuals may encounter the problem of poor blood flow rate when drawing blood, which not only may prolong the collection time, but also may increase the discomfort of patients. In order to cope with this challenge, one widely used auxiliary method is to use a relief ball. By repeatedly squeezing and releasing the relief ball, the activity of the upper limb muscles can be stimulated to promote blood circulation, thereby helping to speed up the blood flow to the punctured site and improve the efficiency of blood drawing. This method is not only suitable for plasma collection, but also can be applied to blood sample collection in various health detection, providing a simple and effective self-help means for donors and patients.

[0004] However, the existing relief ball design has obvious shortcomings. The size and hardness of the ball are fixed, which cannot adapt to the differences in palm size and grip strength of different individuals. For individuals with small palms and weak grip strength, the ball may be too large or too hard to effectively exert force, and may even cause discomfort; while for individuals with wide palms and strong grip strength, the ball may be too small or too soft to provide enough resistance to achieve the expected effect of promoting blood circulation. This limitation in design limits the universality and comfort of the relief ball, affecting its widespread application in blood collection and health detection. SUMMARY

DETAILED DESCRIPTION

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example: A relief device for plasma collection, such as Figures 1-3 As shown, the device includes a seat 1, an air pump 2, an air hose 3, a controller 4, a fixing plate 5, a relief airbag 7, and an adjustment assembly. The air pump 2 is installed at the bottom of the seat 1. The controller 4 is installed at the front end of the top of the armrest of the seat 1. The controller 4 is wired to the air pump 2 and controls the opening and closing of the air pump 2, as well as the amount of air output. The fixing plate 5 is provided on the armrest of the seat 1. The fixing plate 5 has a fastening sliding hole 6. The relief airbag 7 is slidably connected in the fastening sliding hole 6. The relief airbag 7 and the fixing plate 5 are interference fit. The relief airbag 7 can slide in the fastening sliding hole 6, but it needs to be pushed by external force. One end of the air hose 3 is connected to the air pump 2, passes through the middle of the seat 1, and the other end of the air hose 3 is connected to the relief airbag 7. The seat 1 is provided with an adjustment assembly for moving the fixing plate 5 back and forth.

[0021] like Figure 1 and Figure 3 As shown, the adjustment assembly includes a motor 8, a lead screw 9, a movable plate 10, and a cover plate 11. The motor 8 is installed inside the seat 1, and the controller 4 is wired to the motor 8. The lead screw 9 is rotatably connected inside the seat 1, and the rear end of the lead screw 9 is fixedly connected to the output shaft of the motor 8. The fixed plate 5 is slidably connected to the armrest of the seat 1, and the movable plate 10 is connected to the bottom of the fixed plate 5. The movable plate 10 is threadedly connected to the lead screw 9. The cover plate 11 is fixedly connected to the seat 1. The cover plate 11 is located on top of the motor 8 to prevent the blood-drawing personnel from contacting the motor 8 and to insulate the heat emitted by the motor 8 when it is working.

[0022] The first step to obtain blood plasma is to draw blood, and when drawing blood, the blood drawer sits on the seat 1, the armrests on both sides of the seat 1 are provided with relief devices, the medical staff determines the arm for drawing blood, and then performs venous blood drawing. After inserting the needle, the blood drawing rate is observed. If the blood flow rate is slow, the medical staff reminds the blood drawer to take corresponding action. The medical staff starts the air pump 2 through the controller 4. The air pump 2 sends gas to the relief air bag 7 through the air pipe 3. The blood drawer adjusts the height of the relief air bag 7, moves the relief air bag 7 up and down, and moves the relief air bag 7 up and down in the fastening sliding hole 6. When the appropriate height is reached, hold the relief air bag 7, then perform the action of holding and releasing, and inform the medical staff that the relief air bag 7 reaches the appropriate air pressure. The medical staff stops the air pump 2 after listening to the blood drawer's prompt. With the blood drawer's holding and releasing of the relief air bag 7, the blood flow rate in the arm is accelerated, thereby improving the efficiency of blood drawing. The adjustable relief air bag 7 optimizes the applicability of the device, and has high adaptability to different people. After blood drawing is completed, the needle is pulled out to stop bleeding for the blood drawer, and then the air pump 2 is turned off. The air pump 2 no longer maintains the air pressure in the relief air bag 7, and the relief air bag 7 deflates.

[0023] After sitting on the seat 1 to draw blood, the hands naturally hold the relief air bag 7. According to the arm length, the motor 8 is started and adjusted through the controller 4, the lead screw 9 is rotated, and then the moving plate 10 is driven to move forward and backward, so that the fixed plate 5 and the connected relief air bag 7 move forward and backward. According to the length of the blood drawer's arm, the relief air bag 7 can be held after the blood drawer holds it, and the applicability of the device is further optimized.

[0024] As shown in Figure 3 , it also includes a sponge pad 12. The top surface of the fixed plate 5 is provided with a sponge pad 12 for placing the wrist and palm. The sponge pad 12 on the fixed plate 5 can provide a comfortable placement position for the wrist or palm, reducing discomfort during blood drawing.

[0025] As shown in Figure 3 , it also includes an extension pad 13. The seat 1 is connected with the extension pad 13. Two extension pads 13 are respectively connected with the front and rear sides of the fixed plate 5. The other end of the extension pad 13 is connected with the seat 1. The extension pad 13 covers the sliding groove on the top of the lead screw 9, which is used to isolate external objects from the transmission cooperation between the lead screw 9 and the moving plate 10.

[0026] As shown in Figure 1 , it also includes a pipe limiting sleeve 14. The pipe limiting sleeve 14 is connected to the side of the seat 1. The air pipe 3 passes through the middle of the pipe limiting sleeve 14. The pipe limiting sleeve 14 limits the path of the air pipe 3, making the device more concise and neat.

[0027] As shown in Figure 1As shown, the device further comprises a soundproof cover 15 connected to the bottom of the seat 1, which completely covers the air pump 2, thereby reducing the noise generated by the air pump 2.

[0028] The blood drawer sits on the seat 1 and places his hands on the fixed plate 5 of the armrest, which is provided with a sponge pad 12 for comfortable support. By operating the controller 4, the blood drawer or medical staff can start the air pump 2, which inflates the relief air bag 7 through the air pipe 3. The relief air bag 7 is adjusted to an appropriate height in the fixed sliding hole 6 of the fixed plate 5, which is convenient for the blood drawer to hold and release, and this action helps to speed up the blood flow and improve the blood drawing efficiency. At the same time, the motor 8 in the adjusting assembly responds to the instruction of the controller 4 and drives the screw rod 9 to rotate, which drives the moving plate 10 and the fixed plate 5 connected with it to move forward and backward, thereby adjusting the position of the relief air bag 7 according to the length of the blood drawer's arm, so as to ensure that the position of the relief air bag 7 is appropriate. The telescopic pad 13 on the seat 1 covers the sliding groove of the screw rod 9, which not only protects the screw rod 9 from external interference, but also maintains the neatness of the device. The air pipe 3 orderly passes through the pipe limiting sleeve 14 on the side of the seat 1, which keeps the path clear. The soundproof cover 15 at the bottom of the seat 1 effectively reduces the noise generated by the air pump 2 when it works, thereby creating a more peaceful environment for the blood drawer.
