Description

Technical Field

[0001] The invention relates to the technical field of anesthesia appliances, in particular to an antibacterial anesthesia puncture bag. Background Art

[0002] Anesthesia is a reversible functional inhibition of the central nervous system and / or peripheral nervous system produced by drugs or other methods. The main characteristic of this inhibition is the loss of sensation, especially pain, so as to achieve painless surgical treatment and ensure the life safety of patients during the perioperative period.

[0003] In the existing technology, when performing local or general anesthesia on patients, a variety of instruments in a bacteria-proof anesthesia puncture kit are usually used to perform anesthesia operations on patients. The instruments used in the anesthesia process will be placed in different areas after use to facilitate subsequent classification and processing. However, during the anesthesia process, some instruments (such as puncture needles, syringe needles and catheters) need to pierce the human body and penetrate into the human body. After use, blood or tissue fluid will remain on the surface of the instruments, carrying blood-borne pathogens such as hepatitis B and HIV. When placed in different areas, they are exposed to the environment, increasing the possibility of contact transmission and causing the spread of pathogens. In addition, the ends of some instruments are relatively sharp, and the exposed needles can easily injure medical staff during sorting and transportation, thereby causing infection. Even if they are not infected, post-injury testing and preventive medication (such as HIV blocking) will cause long-term psychological pressure on medical staff. Summary of the Invention

[0004] The purpose of the present invention is to provide a bacteria-proof anesthesia puncture kit to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a bacteria-proof anesthesia puncture kit, comprising a storage box, two flip covers hinged to the storage box via rotating rods, a carrying handle rotatably connected to the surface of the flip cover via a rotating column, a carrying plate disposed inside the storage box, and a plurality of placement slots provided on the surface of the carrying plate; The storage box is provided with two U-shaped sliding rods which are elastically arranged laterally by springs, and the sliding rods can move up and down, and the two sliding rods are located under the carrying plate to support the carrying plate, and the sliding rods are inclined on one side close to the rotating rod, and the surface of the rotating rod is fixedly connected to an extrusion block with an arc-shaped side surface and passing through the inner wall of the storage box, and the extrusion block is used to squeeze the sliding rod to move when rotating, and the surface of the sliding rod is fixedly connected to a fixing rod, and a groove is provided on the inner wall of the storage box corresponding to the position of the fixing rod, and a retractable card block with an inclined end is fixedly connected to the surface of the fixing rod, and an L-shaped hook with an inclined end is fixedly connected to the surface of the flip cover close to the groove, and the hook and the card block are staggered. The inner wall surface of the storage box is provided with a limiting mechanism for limiting the sliding rod when the flip cover is fully opened.

[0006] As a further solution of the present invention, the limiting mechanism includes two limiting blocks respectively arranged on the front and rear inner walls of the storage box corresponding to the two sliding rod positions. The ends of the two limiting blocks are retractable and have inclined surfaces. The surface of the sliding rod is provided with limiting holes that are staggered with the limiting blocks.

[0007] As a further solution of the present invention, the front and rear inner walls of the storage box are elastically and slidingly connected with a U-shaped push rod whose two ends are respectively connected to the bottom of the limit block, and the front and rear sides of the inner wall of the storage box are rotatably connected with the drive rod through the drive block. The drive rod is used to drive the push rod to move downward when rotating, and the drive block extends through the storage box to the outside of the storage box, and a special-shaped release groove is provided on the surface of the drive block.

[0008] As a further solution of the present invention, the surface of the rotating column close to the fixed rod is provided with multiple slots arranged at equal angles and with one side being an inclined surface. The inner wall of the flip cover is connected to a card rod which is retractable at the upper end and has inclined surfaces at both ends, and slides up and down corresponding to the position of the rotating column. The bottom of the card rod passes through the flip cover and extends into the groove. When the fixed rod and the card block move, they can squeeze the card rod to move upward.

[0009] As a further solution of the present invention, a sliding groove is provided on the inner wall surface of the flip cover corresponding to the position of the card rod, and an observation port penetrating the outside of the flip cover is provided on the inner wall surface of the sliding groove through a transparent plate. A warning block sliding in the sliding groove is fixedly connected to the surface of the card rod, and when the card rod moves upward into the card slot, the warning block moves synchronously to the observation port position.

[0010] As a further solution of the present invention, a blocking rod is fixedly connected to the surface of the flip cover at a position corresponding to the carrying rod.

[0011] As a further solution of the present invention, the inner wall of the storage box is fixedly connected to limit rods on both sides of the corresponding driving rod, and the two limit rods are respectively located below the two sliding rods.

[0012] As a further solution of the present invention, a synchronization rod is fixedly connected between the driving rods on the front and rear sides.

[0013] As a further solution of the present invention, a stopper is fixedly connected to the inner wall surface of the storage box corresponding to the lower side of the driving rod, and the stopper is used to limit the rotation of the driving rod.

[0014] As a further solution of the present invention, a limiting plate and a limiting block are respectively provided on the surfaces of the two flip covers, the limiting plate is fixedly connected to the flip cover, and the limiting block is slidably connected to the flip cover, and the limiting plate and the limiting block are used to ensure the stable closure of the two flip covers.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention uses a fixing rod, a block and a hook to restrict the flip cover when the instrument is closed again after use after the flip cover is opened during anesthesia of the patient, so as to prevent the flip cover from being opened again after use, resulting in exposure and spread of pathogens. In addition, the flip cover is restricted from opening, so that medical staff can be prevented from being pricked by sharp instruments such as exposed needles when the instruments are transported and transferred. The used instruments are placed in the placement slot again for easy sorting in the later stage, so as to avoid messy placement that increases sorting difficulty and reduces sorting efficiency. In addition, sharp instruments such as needles will be blocked by other instruments and are difficult to be found, which increases the chance of medical staff being pricked.

[0016] The present invention uses the limiting hole and the limiting block to limit the sliding rod during the opening of the flip cover. Then, when the flip cover is closed after anesthesia, the sliding rod, the fixed rod and the clamping block remain stationary under the action of the limiting block, and the clamping block and the hook can be stably engaged to ensure the restriction of the flip cover.

[0017] When the used storage box of the present invention is transported to a specific recycling point, it is necessary to rotate the driving block and the driving rod by utilizing a releasing block with the same shape as the special-shaped releasing groove. When the driving rod rotates, it can push the pushing rod and the limit block to move downward synchronously. After the end of the limit block moves out of the limit hole, the sliding rod will return to its original position under the action of the spring force, the card block will be disengaged from the hook, and the flip cover can be reopened, which is convenient for the processing personnel to sort and classify the used utensils. The releasing groove is set to be special-shaped and needs to be rotated by the corresponding releasing block, which limits the number of people who can open the storage box, reduces the number of unnecessary openings of the storage box, and avoids the spread of germs.

DETAILED DESCRIPTION

[0020] See also Figures 1-13 The present invention provides a technical solution: a bacteria-proof anesthesia puncture kit, comprising a storage box 1, two flip covers 3 hinged to the storage box 1 via a rotating rod 2, a carrying handle 5 rotatably connected to the surface of the flip cover 3 via a rotating column 4, a carrying plate 6 arranged inside the storage box 1, and a plurality of placement slots 7 provided on the surface of the carrying plate 6; Two U-shaped slide bars 8 are provided inside the storage box 1, which are elastically arranged laterally by springs, and the slide bars 8 can move up and down. The two slide bars 8 are located under the carrying plate 6 to support the carrying plate 6. The slide bars 8 are inclined on the side close to the rotating rod 2. The surface of the rotating rod 2 is fixedly connected with an extrusion block 9 with an arc-shaped side and passing through the inner wall of the storage box 1. The extrusion block 9 is used to squeeze the slide bars 8 to move when rotating. The surface of the slide bars 8 is fixedly connected with a fixed rod 10. A groove 11 is provided on the inner wall of the storage box 1 at the position corresponding to the fixed rod 10. A retractable card block 12 with an inclined end is fixedly connected to the surface of the fixed rod 10. An L-shaped hook 13 with an inclined end is fixedly connected to the surface of the flip cover 3 near the groove 11. The hook 13 and the card block 12 are staggered. The inner wall surface of the storage box 1 is provided with a limiting mechanism for limiting the slide bar 8 when the flip cover 3 is fully opened; When the cover 3 is opened, the rotating rod 2 and the extrusion block 9 are rotated synchronously, and the extrusion block 9 squeezes and pushes the slide bar 8, the fixed rod 10 and the card block 12 to move synchronously, and the card block 12 moves to the side close to the hook 13. Then, after the cover 3 is fully opened, the limit mechanism limits the slide bar 8, and the card block 12 is in the initial position of the hook 13. Then, after the anesthesia is completed, the used instrument is placed back in the placement slot 7, the two cover 3 are merged again, and the hook 13 is hooked. When the clamping block 12 is moved to the position, the clamping block 12 is squeezed and contracts and passes over the clamping block 12. The clamping block 12 is engaged with the hook 13 to restrict the flip cover 3, thereby preventing the flip cover 3 from being opened again after use, resulting in the exposure and spread of pathogens. In addition, the flip cover 3 is restricted from opening, which can prevent sharp instruments such as exposed needles from stabbing medical staff during the transportation and transfer of instruments. The used instruments are placed again in the placement slot 7 for later sorting, avoiding messy placement that increases sorting difficulty and reduces sorting efficiency. In addition, sharp instruments such as needles will be blocked by other instruments and are difficult to find, increasing the chance of medical staff being stabbed.

[0021] As a further solution of the present invention, the limiting mechanism includes two limiting blocks 14 respectively arranged on the front and rear inner walls of the storage box 1 corresponding to the positions of the two slide bars 8. The ends of the two limiting blocks 14 are retractable and have inclined surfaces. The surface of the slide bar 8 is provided with limiting holes 15 arranged staggered with the limiting blocks 14. During the opening process of the flip cover 3, the rotating rod 2 and the squeezing block 9 rotate synchronously driven by the flip cover 3, and the squeezing block 9 squeezes and pushes the slide bar 8 to move. When the flip cover 3 is fully opened, the limit hole 15 moves to the position of the limit block 14, and the end of the limit block 14 extends and moves into the limit hole 15 to limit the slide bar 8. Subsequently, when the flip cover 3 is merged after the anesthesia is completed, the slide bar 8, the fixed rod 10 and the card block 12 remain stationary under the action of the limit block 14, and the card block 12 and the hook 13 can be stably engaged to ensure the restriction of the flip cover 3.

[0022] When the used storage box 1 is recycled, the flip cover 3 is still difficult to open, which is inconvenient for recycling and sorting. As a further solution of the present invention, the front and rear inner walls of the storage box 1 are elastically and slidably connected to U-shaped push rods 16, both ends of which are connected to the bottom of the limit block 14 respectively. The front and rear sides of the inner wall of the storage box 1 are rotatably connected to the drive rods 18 through the drive blocks 17. The drive rods 18 are used to drive the push rods 16 to move downward when rotating. The drive block 17 passes through the storage box 1 and extends to the outside of the storage box 1. The surface of the drive block 17 is provided with a special-shaped release groove 19; When transporting the used storage box 1 to a specific recycling point, it is necessary to rotate the driving block 17 and the driving rod 18 by using a release block with the same shape as the special-shaped release groove 19. When the driving rod 18 rotates, it can push the push rod 16 and the limit block 14 to move downward synchronously. After the end of the limit block 14 moves out of the limit hole 15, the slide bar 8 will return to its original position under the action of the spring force, the card block 12 will be disengaged from the hook 13, and the flip cover 3 can be reopened, which is convenient for the processing personnel to sort and classify the used utensils. The release groove 19 is set to be special-shaped and needs to be rotated by the corresponding release block, which limits the number of people who can open the storage box 1, reduces the number of unnecessary openings of the storage box 1, and avoids the spread of germs.

[0023] When anesthetizing a patient, the used storage box 1 is difficult to distinguish from the unused storage box 1. As a further solution of the present invention, a plurality of slots 20 arranged at equal angles and having an inclined surface on one side are provided on the surface of the rotating column 4 near the fixed rod 10. The inner wall of the flip cover 3 is connected to a clip 21 with a retractable upper end and inclined surfaces at both ends, which is slidably connected to the rotating column 4. The bottom of the clip 21 passes through the flip cover 3 and extends into the groove 11. When the fixed rod 10 and the card block 12 move, they can squeeze the clip 21 to move upward. When anesthetizing the patient, the flip cover 3 opens the sliding cover and moves with the fixed rod 10 and the card block 12, and the fixed rod 10 moves to below the initial position of the card rod 21. Then, when the flip cover 3 is merged, the card rod 21 moves into the card slot 20 under the squeezing of the fixed rod 10 to limit the rotating column 4. Then, when the carrying rod 5 is rotated, the card slot 20 can squeeze the end of the card rod 21 to shrink. The card rod 21 and the card slot 20 can limit the rotating column 4 and the carrying rod 5 in one direction. The lifted carrying rod 5 cannot be rotated and lowered again. On the one hand, it is convenient for medical staff to transfer the used storage box 1, and on the other hand, it is convenient for medical staff to distinguish between used and unused storage boxes 1.

[0024] During the anesthesia process for the patient, when the operation is relatively busy, the used storage box 1 and the unused storage box 1 are placed together, and the wrong storage box 1 may still be taken out. As a further solution of the present invention, a sliding groove 22 is provided on the inner wall surface of the flip cover 3 corresponding to the position of the card rod 21, and an observation port 23 is provided on the inner wall surface of the sliding groove 22 through the outer side of the flip cover 3 through a transparent plate. A warning block 24 is fixedly connected to the surface of the card rod 21 and slides in the sliding groove 22. When the card rod 21 moves upward into the card slot 20, the warning block 24 moves synchronously to the position of the observation port 23; During the process of anesthetizing the patient, when the instruments in the storage box 1 are used and the flip cover 3 is closed, the card rod 21 moves upward to the card slot 20 under the squeezing of the fixed rod 10, and the card rod 21 drives the warning block 24 to move upward in the slide groove 22 to the position of the observation port 23. The surface of the warning block 24 is painted with a striking color, which helps medical staff to judge the usage status of the storage box 1 in a very short time when taking it, and avoid taking it by mistake.

[0025] When transferring the used storage box 1, if the rotation angle of the carrying rod 5 is too large, the two carrying rods 5 may be easily intertwined, making it inconvenient to carry the box by hand. As a further solution of the present invention, a blocking rod 25 is fixedly connected to the surface of the flip cover 3 at a position corresponding to the carrying rod 5; When transferring the used storage box 1, the blocking rod 25 can block the carrying rod 5, so that the carrying rods 5 on both sides can be rotated to the corresponding position for easy carrying, avoiding excessive rotation angle of the carrying rod 5, which causes the carrying rods 5 on both sides to be misaligned and inconvenient to carry, and the rotating column 4 is restricted by the clamping rod 21, and the angle of the carrying rod 5 cannot be adjusted back.

[0026] During the anesthesia process for the patient, when the slide bar 8 moves, after the limit hole 15 moves to the position of the limit block 14, the slide bar 8 moves downward significantly under the action of gravity on the carrying plate 6, affecting the subsequent removal. As a further solution of the present invention, the inner wall of the storage box 1 is fixedly connected to the two sides of the corresponding driving rod 18. The two limit rods 26 are respectively located below the two slide bars 8; During the process of anesthetizing the patient, when the slide bar 8 moves, after the limit hole 15 moves to the position of the limit block 14, the slide bar 8 moves downward a certain distance to the position of the limit bar 26 under the action of gravity of the supporting plate 6. The limit bar 26 can limit the slide bar 8 to prevent the slide bar 8 and the supporting plate 6 from moving downward too much and affecting subsequent removal. The short downward movement of the slide bar 8 and the supporting plate 6 can make the used supporting plate 6 away from the upper end of the storage box 1, to prevent the needle at the opening position of the storage box 1 from causing harm to the handling personnel when the flip cover 3 is opened later.

[0027] When the storage box 1 is opened after use, the restrictions on the front and rear sides of the flip cover 3 cannot be released at the same time. As a further solution of the present invention, a synchronization rod 27 is fixedly connected between the front and rear driving rods 18; When the storage box 1 is opened after use, the release block is used to rotate the drive block 17 and the drive rod 18 on one side. The drive rod 18 drives the drive rod 18 on the other side to rotate synchronously through the synchronization rod 27, which can quickly release the restriction of the flip cover 3 and improve operating efficiency.

[0028] When the storage box 1 is opened after use, the driving rod 18 is difficult to rotate and remain vertical. As a further solution of the present invention, a stopper 28 is fixedly connected to the inner wall surface of the storage box 1 corresponding to the bottom of the driving rod 18. The stopper 28 is used to limit the rotation of the driving rod 18; When the storage box 1 is opened after use, the block 28 can block the driving rod 18 when the driving rod 18 rotates, so that the driving rod 18 can be in a vertical state to keep pushing the push rod 16, ensuring that the slide rod 8 is released.

[0029] During the anesthesia process for a patient, the flip cover 3 of the unused storage box 1 is not restricted, and the flip cover 3 is easily opened when the storage box 1 is lifted by the carrying handle 5. As a further solution of the present invention, a restriction plate 29 and a restriction block 30 are respectively provided on the surfaces of the two flip covers 3. The restriction plate 29 is fixedly connected to the flip cover 3, and the restriction block 30 is slidably connected to the flip cover 3. The restriction plate 29 and the restriction block 30 are used to ensure that the two flip covers 3 are stably closed. During the anesthesia process for the patient, the flip cover 3 of the unused storage box 1 is restricted by the restriction block 30 and the restriction plate 29 , and the storage box 1 can be transferred by the carrying rod 5 to ensure the closure of the flip cover 3 .
