Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology; more specifically, it relates to a replaceable blood transfusion pressurization device. Background Technology

[0002] A transfusion pressurization device is a medical device used to improve the efficiency and safety of blood transfusions. It primarily helps maintain appropriate pressure during transfusion to ensure blood flow rate and volume, allowing blood to be delivered quickly and safely to the patient.

[0003] Currently, existing blood transfusion pressurization devices often suffer from several drawbacks. Firstly, most devices use airbags to pressurize blood bags, and these airbags are typically fixed inside the device, making disassembly and replacement difficult. Secondly, in hospital environments prone to bacterial growth, inadequate sterilization can lead to transfusion infections, reducing the device's practicality. Thirdly, existing devices often connect to the blood bag via an IV tubing. During transfusion, the tubing may detach from the blood bag due to accidental contact or other external forces, potentially contaminating the tubing and requiring replacement. This further diminishes the device's usability. Therefore, a replaceable blood transfusion pressurization device is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a replaceable blood transfusion pressurization device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a replaceable blood transfusion pressurization device, comprising:

[0006] The box body has a lid hinged to the outer surface of one end of the upper part of the box body, and the outer surfaces of the hinge shaft at the hinge connection between the box body and the lid are connected to hooks by bearings. The box body and the lid are equipped with a pressurization structure inside, and the other end of the box body and the lid is equipped with an infusion structure. The bottom surface of the box body and the top wall surface of the lid are both equipped with a second Velcro strap, and the inner surface of the other outer surface of the box body and the lid is equipped with a locking groove.

[0007] The pressurization structure includes a pressurization bag and a first Velcro fastener. The pressurization bag is U-shaped and its external dimensions are adapted to the internal dimensions of the box body and the box lid. The first Velcro fastener is provided in two sets, and the two sets of the first Velcro fastener are respectively fixedly connected to the outer surfaces of the upper and lower ends of the pressurization bag.

[0008] The infusion structure includes a blood sac, and the external dimensions of the blood sac are adapted to the internal dimensions of the pressure bag.

[0009] Preferably, the pressurization structure further includes a connecting pipe, and the outer surface of one end of the connecting pipe is fixedly connected to the outer surface of one side of the pressurization bag, and the interior of the connecting pipe is connected to the interior of the pressurization bag. The outer surface of the other end of the connecting pipe penetrates and extends out of the outer surface of one side of the box, and a tubing is inserted into the interior of the outer surface of the other end of the connecting pipe. A vent valve is connected to the interior of the outer surface of the right side of the middle of the tubing, and an inflation ball is connected to the interior of the outer surface of one end of the tubing. A clamp is fitted on the outer surface of one end of the connecting pipe and the outer surface of the other end of the tubing, and bolts are threaded on the inner surfaces of the outer surfaces of both ends of the clamp. This design allows outside air to enter the tubing, connecting pipe and pressurization bag through the inflation ball by squeezing the inflation ball, thereby inflating the pressurization bag.

[0010] Preferably, the pressure bag is made of PU material. This design utilizes the flexibility and elasticity of the PU material to make the pressure bag less prone to damage during use.

[0011] Preferably, the positions of the two sets of first hook and loop fasteners correspond to the positions of the two sets of second hook and loop fasteners. This design allows the pressure bag to be installed inside the box body and the box lid by bonding the two sets of first hook and loop fasteners with the two sets of second hook and loop fasteners.

[0012] Preferably, the infusion structure further includes an output tube, with the outer surface of one end of the output tube fixed to the outer surface of one end of the blood sac, and the interior of the output tube communicating with the interior of the blood sac. The outer surface of the other end of the output tube is provided with a rubber stopper, and a needle is inserted into the rubber stopper. A fixed infusion block is fixedly connected to the outer surface of one end of the needle. Clamping blocks are fitted onto the upper and lower outer surfaces of the output tube, the rubber stopper, and the fixed infusion block. A locking ring is provided on the outer surface of one end of each of the two sets of clamping blocks, and a magnetic connecting post is fixedly connected to the center of the locking ring. The magnetic connecting post is made of magnet material, and the two sets of locking grooves are spaced apart from each other. The inner wall surface of the device has a rectangular slot, and the internal dimensions of the rectangular slot are the same as the external dimensions of the magnetic connecting post. A magnet is installed inside the rectangular slot. The internal dimensions of the locking groove are adapted to the external dimensions of the locking ring. This design involves inserting the needle into the rubber stopper and making the inside of the clamping block fit against the outer surface of the output tube, the rubber stopper, and the fixed infusion block. At the same time, the locking ring at one end of the clamping block and the magnetic connecting post are locked inside the locking groove. Then, the box cover is hinged and rotated to fix the clamping block inside the two sets of locking grooves, thereby fixing the position of the output tube, the rubber stopper, and the fixed infusion block inside the clamping block.

[0013] Preferably, the blood bag is made of PVC material, and the internal dimensions of the clamping block are the same as the external dimensions of the output tube, rubber stopper and fixed infusion block. This design clamps the clamping block through the locking groove, so that the output tube, rubber stopper and fixed infusion block are simultaneously clamped and fixed inside the clamping block, thereby preventing the output tube, rubber stopper and fixed infusion block from coming out of the clamping block.

[0014] The technical effects and advantages of this utility model are as follows: By rotating the bolt, the outer surface of one end of the bolt is separated from the inner surface of the outer surfaces of both ends of the clamp, thereby allowing the clamp to be separated from the outer surface of the connecting tube and the tubing. Then, the tubing is pulled outward, causing the outer surface of the other end of the tubing to be separated from the inner surface of the connecting tube. The two sets of first Velcro fasteners are then separated from the outer surface of the second Velcro fastener, thereby allowing the pressure bag to be simultaneously separated from the inner surface of the box and the box cover. This allows the pressure bag to be disassembled, and the above process can be reversed to install the pressure bag. This facilitates the disassembly, cleaning, and replacement of the pressure bag, enabling the equipment to be better disinfected and avoiding transfusion infections. To a certain extent, this improves the practicality of the equipment.

[0015] By inserting a needle inside the rubber stopper, the infusion tube is connected to the blood sac. The inside of the clamping block is then fitted against the outer surface of the output tube, rubber stopper, and fixed infusion block, causing the locking ring and magnetic connecting post to engage inside the locking groove. Simultaneously, the hinged rotating cover clamps and secures the clamping block within the locking groove. This ensures that the output tube, rubber stopper, and fixed infusion block are simultaneously clamped and secured inside the clamping block. During blood transfusion, this prevents the infusion tube from detaching from the blood sac due to accidental contact or other external forces, thus avoiding contamination of the transfusion tube. This significantly improves the practicality of the device. Furthermore, its overall structure is simple and reasonable, highly practical, and easy to promote and apply. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The medical device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] like Figures 1-4 As shown, this embodiment proposes a replaceable blood transfusion pressurization device, including:

[0024] The box body 1 has a lid 2 hinged to the outer surface of one end of the upper part of the box body 1. The outer surfaces of the hinge shaft at the hinge connection between the box body 1 and the lid 2 are connected to the hooks 3. The box body 1 and the lid 2 are equipped with a pressurization structure 4. The other end of the box body 1 and the lid 2 is equipped with an infusion structure 5. The bottom surface of the box body 1 and the top wall surface of the lid 2 are both equipped with a second Velcro 6. The other outer surface of the box body 1 and the lid 2 are both equipped with a locking groove 7. This design allows the entire device to be hung on the bracket for use via the hooks 3.

[0025] The pressurization structure 4 includes a pressurization bag 41 and a first Velcro 42. The pressurization bag 41 is U-shaped and its external dimensions are adapted to the internal dimensions of the box body 1 and the lid 2. There are two sets of first Velcro 42, and the two sets of first Velcro 42 are respectively fixedly connected to the outer surfaces of the upper and lower ends of the pressurization bag 41. The positions of the two sets of first Velcro 42 correspond to the positions of the two sets of second Velcro 6. This design allows the pressurization bag 41 to be installed inside the box body 1 and the lid 2 by adhering the surfaces of the first Velcro 42 and the second Velcro 6, and the pressurization bag 41 is not easy to deviate from its position inside the box body 1 and the lid 2.

[0026] The pressurization structure 4 also includes a connecting pipe 43, with the outer surface of one end of the connecting pipe 43 fixedly connected to the outer surface of one side of the pressurization bag 41, and the interior of the connecting pipe 43 communicating with the interior of the pressurization bag 41. The outer surface of the other end of the connecting pipe 43 penetrates and extends out of the outer surface of one side of the box 1, and a hose 44 is inserted into the interior of the outer surface of the other end of the connecting pipe 43. A vent valve 45 is connected to the interior of the outer surface of the right side of the middle part of the hose 44, and an inflation ball 46 is connected to the interior of the outer surface of one end of the hose 44. A clamp 47 is fitted on the outer surface of one end of the connecting pipe 43 and the outer surface of the other end of the hose 44, and bolts 48 are threaded on the inner surfaces of the outer surfaces of both ends of the clamp 47. The pressurization bag 41 is made of PU material. This design inserts the outer surface of the other end of the hose 44 into the interior of the connecting pipe 43, and fits the clamp 47 onto the connecting pipe 43. The outer surface of the junction of the connecting pipe 43 and the hose 44 is then rotated. The bolt 48 is then rotated so that the clamp 47 is clamped onto the outer surface of the junction of the connecting pipe 43 and the hose 44, thereby making the connection between the connecting pipe 43 and the hose 44 more stable. At this time, the inflation ball 46 can be pressed to draw outside air into the hose 44 and into the pressure bag 41 through the connecting pipe 43, thereby inflating the pressure bag 41. The PU material of the pressure bag 41 is flexible and elastic, allowing it to withstand a lot of compression and deformation without breaking. When it is necessary to release the air pressure inside the pressure bag 41, the gas inside the pressure bag 41 can be released by opening and closing the vent valve 45. The above process can be reversed to disassemble the pressure structure 4, thereby allowing the pressure bag 41 to be replaced as needed and the inside of the box 1 and the lid 2 to be cleaned.

[0027] Example 2

[0028] like Figure 1 and Figure 4 As shown, based on the same concept as the above embodiments, this embodiment also proposes:

[0029] The infusion structure 5 also includes an output tube 52, with one end of the output tube 52 fixed to the outer surface of one end of the blood bag 51, and the interior of the output tube 52 connected to the interior of the blood bag 51. The other end of the output tube 52 has a rubber stopper 53, and a needle 54 is inserted inside the rubber stopper 53. A fixed infusion block 55 is fixedly connected to the outer surface of one end of the needle 54. Clamping blocks 56 are fitted onto the upper and lower outer surfaces of the output tube 52, the rubber stopper 53, and the fixed infusion block 55. A locking ring is provided on the outer surface of one end of each of the two sets of clamping blocks 56, and a magnetic connecting post 57 is fixedly connected to the center of the locking ring. The magnetic connecting post 57 is made of magnet. Rectangular slots are formed inside the inner wall surfaces of the two sets of locking grooves 7 at their opposite ends. The internal dimensions of the rectangular slots are the same as the external dimensions of the magnetic connecting post 57, and a magnet is provided inside the rectangular slots. The size is adapted to the external size of the locking ring. This design places the blood bag 51 inside the pressure bag 41 and inserts the needle 54 inside the rubber stopper 53. The outer surfaces of the output tube 52, rubber stopper 53 and fixed infusion block 55 are attached to the inside of the clamping block 56. The magnetic connecting post 57 and the magnet inside the rectangular slot attract each other, so that the locking ring and magnetic connecting post 57 at one end of the clamping block 56 are locked in the locking groove 7 and the rectangular slot. At this time, the hinged rotating box cover 2 is used to clamp the locking groove 7 on the outer surface of the clamping block 56, so that the clamping block 56 is clamped on the outer surface of the output tube 52, rubber stopper 53 and fixed infusion block 55. This fixes the position of the output tube 52, rubber stopper 53 and fixed infusion block 55, preventing the rubber stopper 53 from detaching from the needle 54, thereby reducing the risk of infusion tube contamination.

[0030] The blood bag 51 is made of PVC. The internal dimensions of the clamping block 56 are the same as the external dimensions of the output tube 52, the rubber stopper 53 and the fixed infusion block 55. This design utilizes the tensile and impact resistance of the PVC material of the blood bag 51 to prevent the blood bag 51 from being damaged when squeezed inside the pressure bag 41.

[0031] Working principle: When using the equipment, first place the equipment in a suitable position, open the box cover 2 by hinged rotation, and align the positions of the first Velcro 42 and the second Velcro 6, thereby installing the pressure bag 41 inside the box body 1 and the box cover 2, and inserting the other end of the tubing 44 into the connecting tube 43. Next, by fitting the clamp 47 onto the junction of the connecting tube 43 and the tubing 44, and by rotating the bolt 48, the clamp 47 is tightened onto the outer surface of the connecting tube 43 and the tubing 44. Then, the blood bag 51 can be placed inside the pressure bag 41, and the needle 54 is inserted into the rubber stopper 53. The clamping block 56 is attached to the outer surface of the output tube 52, the rubber stopper 53, and the fixed infusion block 55, and the locking ring at one end of the clamping block 56 engages with the magnetic connecting post 57 inside the locking groove 7. At this time, the box cover 2 can be hinged and rotated to close, thereby securing the clamping block 56 into place. The clamping groove 7 is held on the outer surface of the clamping block 56, thereby simultaneously clamping the output tube 52, rubber stopper 53 and fixed infusion block 55 inside the clamping block 56. This fixes the position between the rubber stopper 53 and the needle 54, preventing the needle 54 from dislodging from the rubber stopper 53. At this time, by squeezing the inflation ball 46, the outside air is squeezed into the tubing 44 and enters the pressure bag 41 through the connecting tube 43, thereby pressurizing the blood sac 51 inside the pressure bag 41, so that the blood inside the blood sac 51 is output out through the output tube 52 and the needle 54 for blood transfusion to the patient. After the equipment is used up, the above process can be reversed to disassemble or replace the pressure structure 4 and the infusion structure 5, and the inside of the box 1 and the box cover 2 can be cleaned. The above is the complete working principle of this utility model.

[0032] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
