Description

Technical Field

[0001] The utility model relates to the technical field of blood type detection, in particular to a blood type instrument reagent card grabbing device. Background Art

[0002] Blood typing cards are widely used in the medical field for rapid blood typing. The cards contain a liquid that reacts with blood. An existing patent (Announcement No.: CN211997945U) discloses a blood typing card grabbing clamp. This utility model utilizes a pressurizing device to connect and tighten the blood typing plate to the inner wall of the card slot via a first pressurizing airbag and a clamping airbag, achieving the effect of clamping multiple blood typing plates at once. The second pressurizing airbag then pushes the piston to release the blood typing card from the card slot, making it easy to use. However, in practice, due to the rebound force of the second spring, staff members are required to continuously apply upward pressure to the first pressurizing plate when grabbing the blood typing plate. During the grabbing process, staff members must not let go, otherwise the plate will separate from the card slot, which increases the burden on staff members and leaves room for improvement in practicality. To this end, we propose a blood typing tester reagent card grabbing device. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a blood typing instrument reagent card grabbing device.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A blood typing instrument reagent card grabbing device is designed, comprising a fixed box with multiple clamping plates at the bottom, a pressure chamber provided in the fixed box, a piston plate movably provided in the pressure chamber, pressure plates that can move up and down fixed to the top two ends of the piston plates, an air bag connected to the pressure chamber is provided between adjacent clamping plates, magnetic arms are fixed between the pressure plates, a magnetic strip docked with the magnetic arm is fixed on the top of the fixed box, the magnetic arm and the magnetic strip have opposite magnetic properties, a yield groove is provided on the magnetic arm, and a handle is also installed on the top of the fixed box.

[0006] In the above solution, a return spring is connected between the bottom of the piston plate and the inner wall of the bottom of the pressure chamber, and a cover plate is connected to the fixed box.

[0007] In the above solution, a movable hole cooperating with the pressure plate is opened on the top of the fixed box, and a sealing ring abutting against the pressure plate is installed on the inner wall of the movable hole.

[0008] In the above solution, one side of the pressure plate is provided with a mounting seat fixed to the top of the fixed box, a pressure arm is movably connected between the mounting seat and the top of the pressure plate, and the top of the fixed box is fixed with a guide rod movably passed through the top of the pressure plate.

[0009] In the above scheme, an air tube is connected between the airbag and the pressure chamber, a column structure is evenly provided on the airbag, an extension opening corresponding to the column structure one by one is opened on the splint, a hook noodle is fixed on the back of the airbag, and a wool noodle that cooperates with the hook noodle is fixed on the surface of the splint.

[0010] In the above solution, an air hole communicating with the pressure chamber is opened on one side of the fixed box, and a sealing plug is installed in the air hole.

[0011] In the above solution, a pressure plate is provided on the side of the handle, and the pressure plate is fixed to the pressure arm through a connecting rod.

[0012] The advantages and beneficial effects of the present invention are that: by arranging a fixed box, a pressure plate, a piston plate, a pressure chamber, a magnetic arm, a magnetic strip, a splint and an air bag, the pressure plate is moved downward to move the pressure plate toward the pressure chamber, and then the piston plate squeezes the air flow downward in the pressure chamber, so that the air flow in the pressure chamber enters the air bag, causing the air bag to fully expand and reduce the distance between adjacent splints, thereby achieving the purpose of clamping the blood type card. Compared with the prior art, by moving the pressure plate downward, the magnetic arm is moved downward and adsorbed and fixed to the magnetic strip located at the top of the fixed box, and then the pressure plate is locked at this height, which not only avoids the pressure plate from moving up and down, but also does not need to be continuously controlled by hand, making it more convenient to use. When the blood type card needs to be released, it is only necessary to lift the magnetic arm to disengage it from the magnetic strip and continue to move upward to make the air flow in the air bag return to the pressure chamber, thereby increasing the distance between adjacent splints and facilitating the separation of the blood type card.

The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0019] See also Figure 1-3 , the utility model provides a technical solution: a blood typing instrument reagent card grabbing device, comprising a fixing box 1 with a plurality of clamping plates 20 at the bottom;

[0020] Specifically, such as Figure 1 As shown, the number of the splints 20 is 13 so as to be suitable for a blood typing instrument with 12 card slots. The number of the splints 20 is set according to actual needs.

[0021] A pressure chamber 2 is provided in the fixed box 1, and a piston plate 3 is provided in the pressure chamber 2 to move up and down. Pressure plates 5 that can move up and down are fixed at both ends of the top of the piston plate 3; the position of the piston plate 3 can be controlled by moving the pressure plate 5 up and down.

[0022] Furthermore, a movable hole 6 cooperating with the pressure plate 5 is opened on the top of the fixed box 1, and a sealing ring 7 abutting against the pressure plate 5 is installed on the inner wall of the movable hole 6; the sealing ring 7 is used to improve the sealing performance of the pressure chamber 2 to prevent air leakage.

[0023] Furthermore, a return spring 4 is connected between the bottom of the piston plate 3 and the inner wall of the bottom of the pressure chamber 2. Without applying external force to the pressure plate 5 and the piston plate 3, the return spring 4 can automatically reset the piston plate 3. A cover plate 8 is connected to the fixed box 1, and the four corners of the cover plate 8 are connected to the fixed box 1 by fasteners.

[0024] An air bag 21 communicating with the pressure chamber 2 is provided between adjacent clamping plates 20;

[0025] Furthermore, an air tube 22 is connected between the airbag 21 and the pressure chamber 2, and the air tube 22 is used to allow air to flow between the airbag 21 and the pressure chamber 2. In actual applications, each blood type card is provided with multiple tubes. In order to increase the friction between the airbag 21 and the blood type card, column structures 26 corresponding to the gaps between the tubes are evenly provided on the airbag 21, and extension openings 23 corresponding to the column structures 26 are opened on the splint 20. The extension openings 23 are used to facilitate the insertion of the inflated column structure 26 to prevent the inflated airbag 21 from separating from the splint 20. A hook noodle 25 is fixed to the back of the airbag 21, and a wool noodle 24 that cooperates with the hook noodle 25 is fixed to the surface of the splint 20. The cooperation between the hook noodle 25 and the wool noodle 24 makes it easy to disassemble and assemble the airbag 21 and the splint 20.

[0026] A magnetic arm 12 is fixed between the pressure plates 5, and a magnetic strip 14 is fixed on the top of the fixed box 1 to connect with the magnetic arm 12. The magnetic properties of the magnetic arm 12 and the magnetic strip 14 are opposite. The magnetic arm 12 is coated with a magnetic coating 1, and the magnetic strip 14 is coated with a magnetic coating 2. The magnetic properties of the magnetic coating 1 and the magnetic coating 2 are opposite. Figure 1 As shown, a clearance groove 13 is provided on the magnetic arm 12. When the magnetic arm 12 and the magnetic strip 14 are attracted to each other, the clearance groove 13 is used so that a hand can be inserted into the groove to lift the magnetic arm 12 upward.

[0027] Specifically, by setting a fixed box 1, a pressure plate 5, a piston plate 3, a pressure chamber 2, a magnetic arm 12, a magnetic strip 14, a clamping plate 20 and an air bag 21, by moving the pressure plate 5 downward, the pressure plate 5 moves toward the pressure chamber 2, and then the piston plate 3 squeezes the air flow downward in the pressure chamber 2, so that the air flow in the pressure chamber 2 enters the air bag 21, and the air bag 21 is fully expanded, reducing the distance between adjacent clamping plates 20, thereby achieving the purpose of clamping the blood type card. Compared with the prior art, by moving the pressure plate downward, the pressure plate 5 moves toward the pressure chamber 2, and the piston plate 3 squeezes the air flow downward in the pressure chamber 2, so that the air flow in the pressure chamber 2 enters the air bag 21, and the air bag 21 is fully expanded, reducing the distance between adjacent clamping plates 20, thereby achieving the purpose of clamping the blood type card. 5, the magnetic arm 12 moves downward and is fixed to the magnetic strip 14 on the top of the fixed box 1, thereby locking the pressure plate 5 at this height, which not only prevents the pressure plate 5 from moving up and down, but also eliminates the need to continuously control the pressure plate 5 by hand, making it more convenient to use. When the blood type card needs to be released, it is only necessary to lift the magnetic arm 12 to separate it from the magnetic strip 14 and continue to move it upward, so that the airflow in the airbag 21 can be returned to the pressure chamber 2, thereby increasing the distance between adjacent splints 20 and facilitating the separation of the blood type card.

[0028] Furthermore, a mounting base 10 fixed to the top of the fixed box 1 is provided on one side of the pressure plate 5, and a pressure arm 11 is movably connected between the mounting base 10 and the top of the pressure plate 5. The two ends of the pressure arm 11 are movably connected to a rotating shaft 1 and a rotating shaft 2, respectively. The other end of the rotating shaft 1 is fixed to the mounting base 10, and the other end of the rotating shaft 2 is fixed to the pressure plate 5. A guide rod 9 movably passed through the top of the pressure plate 5 is fixed to the top of the fixed box 1, and a socket for cooperating with the guide rod 9 is opened on the top of the pressure plate 5;

[0029] A handle 17 is also installed on the top of the fixed box 1;

[0030] Furthermore, a pressure plate 16 is provided on the side of the handle 17, and the pressure plate 16 is fixed to the pressure arm 11 through a connecting rod 15; when the handle 17 is held by the hand, the pressure plate 16 can be pressed down with the thumb, thereby driving the pressure arm 11 to move downward, thereby moving the pressure plate 5 downward.

[0031] Furthermore, an air hole 18 communicating with the pressure chamber 2 is opened on one side of the fixed box 1 , and a sealing plug 19 is installed in the air hole 18 , through which gas can be replenished.
