Description

Technical Field

[0001] The invention relates to the technical field of medical disinfection equipment, in particular to a disinfection box for cardiovascular surgery. Background Art

[0002] A variety of medical instruments are used in cardiovascular surgery, such as surgical knives, scissors, vascular clamps, needle holders, cardiovascular endoscopes, etc. Medical instruments must be disinfected after use. For complex and precise medical instruments such as cardiovascular endoscopes, a special disinfection box is needed to fix and support the endoscope during disinfection to prevent scratches or collisions of the cardiovascular endoscope during the disinfection process. Specifically, before placing the cardiovascular endoscope in the disinfectant, the staff needs to disassemble the cardiovascular endoscope first, and then insert the disassembled parts of the endoscope into the corresponding slots in the disinfection box. After the parts of the endoscope are firmly fixed, the disinfection box is placed in the disinfectant for disinfection.

[0003] Although the existing medical disinfection box can basically meet the use requirements, it still has certain defects when in use: since the various components of the cardiovascular endoscope are stuck in the corresponding card slots in the disinfection box, the part of the cardiovascular endoscope that contacts the card slot cannot be fully in contact with the disinfectant. Therefore, after the cardiovascular endoscope is taken out of the disinfection box, medical staff are required to use a disinfectant spray to disinfect the area separately, which will undoubtedly cause an additional burden on the daily work of medical staff. In addition, once the medical staff ignores this problem and fails to disinfect the area of ​​the cardiovascular endoscope separately, then when the cardiovascular endoscope is inserted into the patient's blood vessels, it is easy to cause bacterial infection in the patient, causing unnecessary pain to the patient. Summary of the invention

[0004] Based on this, it is necessary to provide a cardiovascular surgery disinfection box to address the problems existing in the current medical disinfection box, so as to solve the problem that the part of the cardiovascular endoscope that contacts the card slot cannot fully contact with the disinfectant.

[0005] The above purpose is achieved through the following technical solutions:

[0006] A cardiovascular surgery disinfection box comprises:

[0007] A box body, with an open top and holes in the surrounding walls;

[0008] The box cover and the box body circumferentially enclose a chamber, and the box cover can reciprocate up and down along the opening to change the volume of the chamber;

[0009] A buoyancy plate is also slidably provided in the box body, and the buoyancy plate can move up and down in the box body. A plurality of first clamping assemblies are arranged at intervals on the upper surface of the buoyancy plate, and the first clamping assemblies are used to clamp the structural parts to be sterilized;

[0010] A plurality of second clamping assemblies are arranged at intervals on the lower surface of the box cover, and the second clamping assemblies are also used to clamp the structural parts to be sterilized, and the first clamping assembly and the second clamping assembly are arranged in a staggered manner;

[0011] During the process of the structure to be sterilized moving from top to bottom, the first clamping assembly stops clamping the structure to be sterilized, and the second clamping assembly clamps the structure to be sterilized and moves synchronously from top to bottom;

[0012] During the process of the structure to be sterilized moving from bottom to top, the second clamping assembly stops clamping the structure to be sterilized, and the first clamping assembly clamps the structure to be sterilized and moves synchronously from bottom to top.

[0013] In one embodiment, the first clamping assembly includes a first elastic block and two first buoyancy balls. The first elastic block is arranged on the upper surface of the buoyancy plate. A V-shaped groove is opened on the upper surface of the first elastic block, and the V-shaped groove faces upward. The two first buoyancy balls are respectively arranged at both ends of the V-shaped groove, and the two first buoyancy balls are abutted against each other.

[0014] In one embodiment, the second clamping assembly includes a second elastic block and two second buoyancy balls. The second elastic block is arranged on the lower surface of the box cover. The lower surface of the second elastic block is also provided with a V-shaped notch, and the V-shaped notch faces downward. The two second buoyancy balls are respectively arranged at both ends of the V-shaped notch, and the two second buoyancy balls are abutted against each other.

[0015] When the first clamping assembly and the second clamping assembly are located above the liquid surface of the disinfectant, the abutting force of the two second buoyancy balls is greater than the abutting force of the two first buoyancy balls.

[0016] In one of the embodiments, a stop assembly is further provided on the box body, and when the buoyancy board moves to the lower limit position, the stop assembly limits the upward movement of the buoyancy board, and when the box cover moves upward to a preset position, the stop assembly stops limiting the upward movement of the buoyancy board.

[0017] In one embodiment, the stop assembly includes a stop plate and a first elastic member, the stop plate is C-shaped, and two through grooves are provided on the left and right side walls of the box body, the through grooves extend in the left and right directions, the two through grooves are spaced up and down, and the upper and lower ends of the stop plate slide through the corresponding through grooves respectively, and the first elastic member is arranged between the stop plate and the side wall of the box body, the upper surface of the upper end of the stop plate is provided with a first inclined guide surface, and the lower surface of the upper end of the stop plate is provided with a second inclined guide surface, the first inclined guide surface and the second inclined guide surface are arranged in opposite directions, and the upper surface of the lower end of the stop plate is provided with a third inclined guide surface, the inclination direction of the third inclined guide surface is the same as that of the first inclined guide surface, and the lower surface of the lower end of the stop plate is a plane.

[0018] In one of the embodiments, a side handle is provided on the outer side of the stop plate.

[0019] In one of the embodiments, a through hole is formed at the upper end of the box cover, and the through hole connects the inside and the outside of the box body.

[0020] In one of the embodiments, an upper handle is provided on the upper surface of the box cover.

[0021] In one embodiment, the elastic coefficient of the first elastic block is smaller than that of the second elastic block.

[0022] In one embodiment, the first buoyancy ball and the second buoyancy ball have the same diameter and are both stainless steel hollow balls.

[0023] The beneficial effects of the present invention are:

[0024] The present invention is provided with a first clamping assembly and a second clamping assembly. Since the first clamping assembly and the second clamping assembly are staggered, the positions of the structural member clamped by the first clamping assembly and the second clamping assembly are different. When the first clamping assembly clamps the structural member, the position where the structural member is clamped by the second clamping assembly is directly in contact with the disinfectant. When the second clamping assembly clamps the structural member, the position where the structural member is clamped by the first clamping assembly is directly in contact with the disinfectant. Therefore, during the process of cleaning the structural member in the disinfectant, there is no blind spot for cleaning, and all parts of the surface of the structural member can fully contact with the disinfectant. Therefore, the structural member can be fully cleaned and disinfected by the disinfectant, and there is no need to manually clean the uncleaned area of ​​the structural member later, thereby avoiding causing additional burden to the daily work of medical staff.

[0038] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below through embodiments and in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0039] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings). In the description of the present invention, it should be understood that the orientation or position relationship indicated by the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc. are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0040] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0041] like Figure 1-Figure 6 As shown, a cardiovascular surgical disinfection box includes a box body 100 and a box cover 110. The box body 100 has an opening at the top and holes in the peripheral wall. The box cover 110 and the box body 100 circumferentially enclose a chamber. The box cover 110 can reciprocate up and down along the opening to change the volume of the chamber. A buoyancy plate 120 is also slidably provided in the box body 100. The buoyancy plate 120 can move up and down in the box body 100. A plurality of first clamping assemblies 200 are arranged at intervals on the upper surface of the buoyancy plate 120. The first clamping assemblies 200 are used to clamp the structural member 500 to be disinfected. A plurality of second clamping assemblies 300 are arranged at intervals on the lower surface of the box cover 110. The second clamping assembly 300 is also used to clamp the structure 500 to be sterilized. The first clamping assembly 200 and the second clamping assembly 300 are staggered. When the structure 500 to be sterilized moves from top to bottom, the first clamping assembly 200 cancels clamping the structure 500 to be sterilized, and the second clamping assembly 300 clamps the structure 500 to be sterilized and moves synchronously from top to bottom. When the structure 500 to be sterilized moves from bottom to top, the second clamping assembly 300 cancels clamping the structure 500 to be sterilized, and the first clamping assembly 200 clamps the structure 500 to be sterilized and moves synchronously from bottom to top.

[0042] When in use, the staff first disassembles the cardiovascular endoscope into various structural parts 500 to be disinfected, and then uses the second clamping assembly 300 to clamp each structural part 500. Next, the box body 100 is placed in the disinfection pool 600. Then the staff presses down the box cover 110, so that the box cover 110 drives the structural parts 500 to move from top to bottom, so that the structural parts 500 are immersed in the disinfectant. In the process of the box cover 110 moving downward, the buoyancy plate 120 is also moved synchronously from top to bottom. After the box cover 110 and the buoyancy plate 120 move to the lower limit position (that is, the buoyancy plate 120 contacts the bottom of the box body 100, and the box cover 110 contacts the buoyancy plate 120), the first clamping assembly 200 clamps the structural parts 500 to be disinfected and moves synchronously from bottom to top. Since the first clamping assembly 200 and the second clamping assembly 300 are staggered, the first clamping assembly 200 The position where the first clamping assembly 200 clamps the structural member 500 is different from that where the second clamping assembly 300 clamps the structural member 500. When the first clamping assembly 200 clamps the structural member 500, the position where the structural member 500 is clamped by the second clamping assembly 300 is exposed to the disinfectant, and this position of the structural member 500 is in direct contact with the disinfectant. When the second clamping assembly 300 clamps the structural member 500, the position where the structural member 500 is clamped by the first clamping assembly 200 is directly exposed to the disinfectant, and this position of the structural member 500 is in direct contact with the disinfectant. Therefore, during the cleaning of the structural member 500 in the disinfectant, there is no blind spot for cleaning, and all parts of the surface of the structural member 500 can fully contact with the disinfectant. Therefore, the structural member 500 can be fully cleaned and disinfected by the disinfectant, and there is no need to manually clean the uncleaned area of ​​the structural member 500, thereby avoiding causing additional burden to the daily work of medical staff.

[0043] It should also be noted that the holes are opened on the peripheral wall of the box body 100 to enhance the flow of the disinfectant so that the disinfectant can move relative to the structural member 500, thereby producing a flushing effect on the structural member 500 and preventing dirt from adhering to the surface of the structural member 500 and causing poor disinfection effect.

[0044] In a further embodiment, Figure 6 As shown, the first clamping assembly 200 includes a first elastic block 210 and two first buoyancy balls 220. The first elastic block 210 is arranged on the upper surface of the buoyancy plate 120. A V-shaped groove is opened on the upper surface of the first elastic block 210, and the V-shaped groove faces upward. The two first buoyancy balls 220 are respectively arranged at both ends of the V-shaped groove, and the two first buoyancy balls 220 are abutted against each other.

[0045] When in use, the staff pushes the second buoyancy ball 320 away from each other, and then places the structural member 500 into the V-shaped groove of the first elastic block 210. At this time, under the elastic action of the second elastic block 310, the two second buoyancy balls 320 approach each other and abut against each other. At this time, the structural member 500 is supported by the second buoyancy ball 320 and clamped in the V-shaped groove of the second elastic block 310. At this time, when the box cover 110 moves downward, it can drive the structural member 500 to move downward synchronously.

[0046] In a further embodiment, Figure 6 As shown, the second clamping assembly 300 includes a second elastic block 310 and two second buoyancy balls 320. The second elastic block 310 is arranged on the lower surface of the box cover 110. The lower surface of the second elastic block 310 is also provided with a V-shaped groove, and the V-shaped groove faces downward. The two second buoyancy balls 320 are respectively arranged at both ends of the V-shaped groove, and the two second buoyancy balls 320 are abutted against each other. When the first clamping assembly 200 and the second clamping assembly 300 are located above the liquid surface of the disinfectant, the abutment force of the two second buoyancy balls 320 is greater than the abutment force of the two first buoyancy balls 220.

[0047] When the box cover 110 moves downward, the buoyancy plate 120 also moves downward synchronously. After the buoyancy plate 120 moves to contact the bottom of the box body 100, as the box cover 110 continues to move downward, the structural member 500 gradually pushes the two first buoyancy balls 220 apart, so that the two first buoyancy balls 220 move away from each other, so that the structural member 500 is simultaneously stuck in the V-shaped notch of the second elastic block 310 and the V-shaped notch of the first elastic block 210. Next, the buoyancy plate 120 is first fixed to the bottom of the box body 100. Then, the box cover 110 is moved upward. At this time, the first buoyancy ball 220 is acted upon by buoyancy so that the abutting force between the two first buoyancy balls 220 increases, and the second buoyancy ball 320 is acted upon by buoyancy so that the abutting force between the two second buoyancy balls 320 decreases. Therefore, when the box cover 110 moves upward from bottom to top, the structural member 500 is separated from the second buoyancy ball 320. At this time, the structural member 500 is clamped on the first elastic block 210, so the structural member 500 continues to be immersed in the disinfectant for disinfection. After a certain period of time, Next, the buoyancy plate 120 is unfixed at the bottom of the box body 100. At this time, under the action of buoyancy, the buoyancy plate 120 moves upward from bottom to top, and the buoyancy plate 120 drives the structural member 500 to move upward through the first buoyancy ball 220. When the first buoyancy ball 220 moves upward to above the liquid surface of the disinfectant, the structural member 500 pushes the two second buoyancy balls 320 away, so that the structural member 500 is again stuck in the V-shaped groove of the second elastic block 310 and the V-shaped groove of the first elastic block 210 at the same time. At this time, the first buoyancy ball 220 and the second buoyancy ball 320 are not affected by buoyancy. Since the abutting force of the two second buoyancy balls 320 is greater than the abutting force of the two first buoyancy balls 220, when the staff pushes the buoyancy plate 120 downward, the structural member 500 moves out of the V-shaped groove of the first buoyancy ball 220. At this time, the box cover 110 and the buoyancy plate 120 are both reset to the initial position. Then, repeat the above operation to make the structural member 500 move back and forth up and down in the disinfectant, thereby completing the cleaning of the structural member 500.

[0048] It is understandable that when the box cover 110 moves downward, the structural member 500 contacts the first buoyancy ball 220 and applies a downward force to the first buoyancy ball 220, so that the first buoyancy ball 220, the first elastic block 210 and the buoyancy plate 120 move downward synchronously, thereby achieving the box cover 110 moving downward while also causing the buoyancy plate 120 to move downward synchronously. Although the downward movement of the buoyancy plate 120 is achieved by applying a downward force to the buoyancy plate 120 through the contact between the first buoyancy ball 220 and the structural member 500, the first buoyancy ball 220 and the structural member 500 are in point contact, so the contact area is very small and will not affect the disinfection of the structural member 500.

[0049] In a further embodiment, Figure 2 and Figure 5As shown, a stop assembly 400 is also provided on the box body 100. When the buoyancy board 120 moves to the lower limit position, the stop assembly 400 limits the buoyancy board 120 from moving upward. When the box cover 110 moves upward to a preset position, the stop assembly 400 cancels the limit on the buoyancy board 120 from moving upward.

[0050] During use, when the buoyancy plate 120 moves downward to the bottom of the box body 100, the buoyancy plate 120 is stopped by the stopping assembly 400 to limit the upward movement of the buoyancy plate 120. Therefore, when the box cover 110 moves upward, the structural member 500 can be clamped on the first clamping assembly 200. When the box cover 110 moves upward to a preset position, the stopping assembly 400 stops limiting the upward movement of the buoyancy plate 120. At this time, the buoyancy plate 120 moves upward under the action of buoyancy until the first elastic block 210 moves upward to above the liquid surface of the disinfectant.

[0051] In a further embodiment, Figure 5 As shown, the stopping assembly 400 includes a stopping plate 410 and a first elastic member 420. The stopping plate 410 is C-shaped. Two through grooves 101 are provided on the left and right side walls of the box body 100. The through grooves 101 extend in the left and right directions. The two through grooves 101 are spaced apart up and down. The upper and lower ends of the stopping plate 410 slide through the corresponding through grooves 101 respectively. The first elastic member 420 is arranged between the stopping plate 410 and the side wall of the box body 100. A first inclined guide surface 411 is provided on the upper surface of the upper end of the stopping plate 410, and a second inclined guide surface 412 is provided on the lower surface of the upper end of the stopping plate 410. The first inclined guide surface 411 and the second inclined guide surface 412 are arranged in opposite directions. A third inclined guide surface 413 is provided on the upper surface of the lower end of the stopping plate 410. The inclination direction of the third inclined guide surface 413 is the same as that of the first inclined guide surface 411. The lower surface of the lower end of the stopping plate 410 is a plane 414.

[0052] When in use, when the buoyancy board 120 moves downward until the buoyancy board 120 abuts against the third inclined guide surface 413, the buoyancy board 120 continues to move downward, and the stop plate 410 moves away from the box body 100 through the third inclined guide surface 413, and the first elastic member 420 is gradually stretched. When the buoyancy board 120 moves over the stop plate 410, the stop plate 410 is reset under the elastic action of the first elastic member 420. At this time, the plane 414 blocks the buoyancy board 120 from moving upward, so that the buoyancy board 120 is fixed to the box body. The bottom of the box body 100 is formed by the box cover 110, so when the box cover 110 moves upward, the structural member 500 can be clamped on the first clamping assembly 200. When the box cover 110 moves upward until the upper end surface of the box cover 110 contacts the second inclined guide surface 412, the box cover 110 pushes the stop plate 410 away from the box body 100 through the second inclined guide surface 412, so that the plane 414 no longer stops the buoyancy plate 120. At this time, the buoyancy plate 120 moves upward under the action of buoyancy until the first elastic block 210 follows the buoyancy plate 120 and moves upward to above the liquid surface of the disinfectant.

[0053] It is understandable that the first inclined guide surface 411 is used to push the stop plate 410 away when the box cover 110 and the buoyancy plate 120 move downward, so as to prevent the stop plate 410 from interfering with the downward movement of the box cover 110 and the buoyancy plate 120 .

[0054] In a further embodiment, Figure 5 As shown, a side handle 430 is provided on the outer side of the stop plate 410 .

[0055] The side handle 430 is provided to facilitate the staff to disassemble and assemble the stop plate 410 and to take the box body 100 out of the disinfection pool 600.

[0056] In a further embodiment, a through hole 111 is formed at the upper end of the box cover 110 , and the through hole 111 communicates with the inside and outside of the box body 100 .

[0057] A through hole 111 is provided at the upper end of the box cover 110 to increase the fluidity of the disinfectant.

[0058] In a further embodiment, an upper handle 130 is disposed on the upper surface of the box cover 110 .

[0059] The upper handle 130 is provided to facilitate the staff to pull the box cover 110 up and down. In other embodiments, a mechanical arm may also be provided to drive the box cover 110 up and down, so as to avoid contact between the human body and the disinfectant, reduce damage to the human body and prevent the disinfectant from being contaminated.

[0060] In a further embodiment, the elastic coefficient of the first elastic block 210 is smaller than that of the second elastic block 310 .

[0061] In this way, when the first elastic block 210 and the second elastic block 310 produce the same elastic deformation, the abutting force between the two first buoyancy balls 220 is greater than the abutting force between the two second buoyancy balls 320 .

[0062] In a further embodiment, the first buoyancy ball 220 and the second buoyancy ball 320 have the same diameter and are both stainless steel hollow balls.

[0063] The first buoyancy ball 220 and the second buoyancy ball 320 are made of stainless steel because stainless steel is not only relatively hard, but also not easy to rust after being immersed in disinfectant for a long time. In addition, stainless steel is light in weight, which is conducive to making hollow buoyancy balls.

[0064] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
