Description

Technical Field

[0001] The invention relates to the technical field of medical device sterilization, in particular to a medical device drying and sterilization device. Background Art

[0002] The residual moisture after cleaning medical devices is a breeding ground for microorganisms, especially in a humid environment where biofilms may form quickly. Thorough drying can eliminate the living conditions of microorganisms and reduce the risk of contamination in the pretreatment stage. Medical devices mostly use an integrated drying and sterilization process, such as thermal drying sterilization.

[0003] The Chinese utility model patent with the authorization announcement number CN209236919U: A drying and sterilizing device for medical devices, including a box, a movable box is fixedly connected to the top of the box, a fixed plate is fixedly connected to the top of the inner wall of the movable box, one side of the fixed plate is rotatably connected to a rotating shaft through a bearing, the outer surface of the rotating shaft is fixedly connected to a first pulley, one end of the rotating shaft passes through the fixed plate and extends to the other side of the fixed plate, the rotating shaft extends to the outer surface of one end of the other side of the fixed plate and is fixedly connected to a disc, and the top of one side of the disc is fixedly connected to a convex rod. This solution can sterilize medical devices uniformly and comprehensively through the movement of the sterilization tank, but there is a risk of medical devices bumping into each other. This solution has high spatial requirements for individual medical devices and cannot perform intensive and centralized sterilization of medical devices.

[0004] The Chinese utility model patent with authorization announcement number CN206534894U: A medical scalpel sterilization and drying device discloses that by starting the first cylinder to intermittently extend and shorten, the wedge block is driven to move left and right intermittently, so that the scalpel moves up and down. At the same time, the first cylinder drives the first nozzle and the second nozzle to move up and down, which can perform normal drying and sterilization effects on the scalpel. However, there are technical problems such as low sterilization efficiency and many sterilization dead corners.

[0005] In the prior art, during the sterilization and drying process of medical devices, there are many dead corners, and thorough sterilization and drying cannot be achieved. For example, when the orthopedic forceps are opened to any degree, there will be blocked dead corners of varying sizes near the rotating shaft, and the intersection area of the two elastic sheets used to open the forceps handles also has a dead corner. The prior art cannot dynamically air-dry and sterilize the dead corners of medical devices, so the field is in urgent need of a medical device drying and sterilization device to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to provide a technical solution for a medical device drying and sterilization device to solve the technical problem that the prior art cannot dynamically air dry and sterilize the blind spots of medical devices.

[0007] To achieve the above object, the present invention provides the following technical solution: A medical device drying and sterilizing device, including a housing, the internal space of the housing is communicated with a hot air circulation supply device, and ultraviolet sterilization lamps are installed on the inner wall of the housing; the sterilization device further includes a support frame installed inside the housing, and a plurality of supporting components are arranged in an array on the support frame; The supporting component includes a supporting base block fixed on the support frame. At both ends of the upper surface of the supporting base block, a fixing block is respectively fixedly installed. A first through hole is horizontally opened in the center of the fixing block. One end of the fixing block close to the center of the supporting base block is fixedly connected with an elastic telescopic sleeve. The first through hole is hermetically communicated with the elastic telescopic sleeve. One end of the elastic telescopic sleeve close to the center of the supporting base block is fixedly connected with a pressing seat, and the pressing seat can perform a horizontal displacement following the expansion and contraction of the elastic telescopic sleeve; a fluid supply device is hermetically communicated with the first through hole at the end far from the elastic telescopic sleeve; the fluid supply device is signal-connected to a control system; With the above technical solution, for a medical instrument with a clamping function, such as an orthopedic forceps, with the forceps head facing upwards, the two ends of the bottom forceps handle are respectively abutted against the end faces of the two pressing seats. By using the elasticity of the elongation trend of the elastic telescopic sleeves at both ends, the orthopedic forceps can be erected with the forceps head facing upwards to complete the clamping of the orthopedic forceps. In the state without external force, the elastic telescopic sleeves are in a retracted state. After clamping the orthopedic forceps, the air pump is driven to supply air into the first through hole. The air pressure in the elastic telescopic sleeves increases, the elastic telescopic sleeves elongate, and the two pressing seats slide closer to each other, with the distance decreasing, causing the forceps head of the orthopedic forceps to have a tendency to open and the central rotating shaft of the orthopedic forceps to have a tendency to rotate; the above process of using gas pressure to push the orthopedic forceps to open is a slow process. After the forceps head of the orthopedic forceps is fully opened, the air supply power of the air pump is slowly reduced, so that the elastic telescopic sleeves retract under the action of the elastic restoring force, and the orthopedic forceps also return to the state where the forceps head is closed. A program is written to control the orthopedic forceps to continuously and repeatedly open and close. During this process, the hot air circulation supply device continuously supplies dry hot air into the housing, and the orthopedic forceps can be air-dried and sterilized without dead angles. For the orthopedic forceps in the open state of the forceps head, the clamping surface of the forceps head can be air-dried and sterilized with high efficiency.

[0008] As a preferred solution, the supporting component further includes two clamping pieces installed in parallel. The clamping piece includes an outer clamping piece with a plurality of dense second through holes penetrating the surface, and the bottom end of the outer clamping piece is fixedly connected with the supporting base block; With the above technical solution, for the erected orthopedic forceps clamped by the pressing seats, the two outer clamping pieces respectively block both sides of the orthopedic forceps, which can improve the stability of the orthopedic forceps during the air-drying and sterilizing process and can continuously maintain the erected state with high stability. Compared with the prior art of directly placing medical devices flat in a disinfection cabinet for air-drying and disinfection, the contact area of this solution with medical devices is small, and the medical devices can be air-dried and disinfected with high efficiency and in all directions.

[0009] As a preferred solution, an inner clamping piece is fixedly attached to one end of the outer clamping piece close to the other outer clamping piece. A plurality of third through-holes equal in number to the second through-holes are formed through the inner clamping piece. The second through-holes and the third through-holes correspond to each other one by one, and the axes of the third through-holes coincide with the axes of the second through-holes. A dense clamping protrusion is integrally formed on the side wall of the inner clamping piece away from the outer clamping piece. The clamping protrusion plays a role in flexibly clamping the medical device, improving the stability of the medical device during air drying and disinfection in a point-contact manner. At the same time, it has the advantage of a small clamping contact area, which can reduce the dead corners of air drying and disinfection of the medical device, and the air drying and disinfection effect is more thorough.

[0010] As a preferred solution, a dense supporting protrusion is integrally formed on the side wall of the inner clamping piece away from the outer clamping piece. The length of the supporting protrusion is greater than the length of the clamping protrusion. The supporting protrusion plays a role in supporting the medical device, enabling the clamping of non-clamping medical devices. The clamping function of the clamping protrusion and the supporting function of the supporting protrusion can clamp the non-clamping medical device above the supporting base block.

[0011] As a preferred solution, both the clamping protrusion and the supporting protrusion are of a cylindrical structure. The end face diameter of the clamping protrusion is greater than the end face diameter of the supporting protrusion, making the clamping protrusion have the characteristic of being not easily deformed and the supporting protrusion have the characteristic of being easily deformed. When air drying and disinfecting a medical device with a clamping function, such as an orthopedic forceps, the clamping protrusions on the two inner clamping pieces can be in close contact with the surface of the orthopedic forceps, and can limit the orthopedic forceps in a direction perpendicular to the clamping direction of the pressing seat. During the opening and closing of the jaws of the orthopedic forceps, the surface of the orthopedic forceps can easily press through the supporting protrusions and then contact different clamping protrusions in the real-time state, so that the clamping protrusions continuously limit the orthopedic forceps; in actual application, the clamping and supporting effects of the clamping protrusions and the supporting protrusions on special-shaped medical devices are more obvious, such as grasping forceps. Because the center of gravity of the special-shaped medical device deviates far from the forceps handle, it is easy to produce the phenomenon that the end of the forceps handle breaks away from the pressing seat under the influence of gravity. In this solution, the clamping and supporting functions of the clamping protrusions and the supporting protrusions can be used to reduce the negative effect of the special-shaped medical device tipping caused by gravity, making the air drying and disinfection process stable; As a preferred solution, the end face diameter of the supporting protrusion is equal to that of the clamping protrusion, which can enable the supporting protrusion to have better supporting performance. During the air drying and disinfection process of the orthopedic forceps, after the jaws of the orthopedic forceps are fully opened, the position of the rotation axis of the orthopedic forceps will rise to the highest point. Then, the jaws tend to close, and the two forceps handles tend to open. When the jaws just start to close, the included angle of the forceps handles below the rotation axis of the orthopedic forceps will be limited and supported by the supporting protrusion. The supporting protrusion is stuck in the included angle of the forceps handles, cooperating with the supporting function of the supporting protrusions in other areas and the static friction clamping of the clamping protrusions, causing the orthopedic forceps to hover, and the bottom of the forceps handle is separated from the extrusion seat, and there is no obstruction at the bottom of the forceps handle. At this time, the bottom of the forceps handle can be effectively and thoroughly air dried and sterilized.

[0012] As a preferred solution, the inner clamping piece, the clamping protrusion, and the supporting protrusion are all made of rubber material, and the inner clamping piece is adhesively fixed to the outer clamping piece.

[0013] As a preferred solution, the aperture of the third through hole is larger than that of the second through hole, which can facilitate the replacement operation of the inner clamping piece after the supporting protrusion or the clamping protrusion is worn.

[0014] As a preferred solution, a bending edge is formed by bending the bottom end of the outer clamping piece, and the bending edge and the supporting base block are fixedly connected by fasteners, realizing the fixing function of the outer clamping piece, and having the beneficial effect of facilitating the disassembly and assembly of the outer clamping piece.

[0015] As a preferred solution, the fluid supply device is an air pump.

[0016] As a preferred solution, the bottom surface of the extrusion seat is slidably connected to the supporting base block by a slide rail and a chute, which can improve the sliding stability of the extrusion seat.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention adopts the combination of hot air circulation and ultraviolet irradiation, which can efficiently air dry and sterilize medical devices.

[0018] 2. The present invention designs a supporting component, which can vertically place and densely array medical devices, improve space utilization rate, and reduce the overall volume of the device.

[0019] 3. The present invention can dynamically dry and sterilize medical devices, making the medical devices have no dead corners to hide, and improving the drying and sterilization efficiency.

[0020] 4. The present invention designs a way of static friction clamping and supporting medical devices, which can be applicable to various shaped medical devices and has high practicability. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment: AsFigures 1 - 12 As shown in the figure, the present invention provides a drying and sterilizing device for medical devices, including a housing 101. The internal space of the housing 101 is connected to a hot air circulation supply device, and an ultraviolet sterilization lamp is installed on the inner wall of the housing 101. The sterilization device further includes a support frame 102 installed inside the housing 101, and a supporting component 200 is arrayed on the support frame 102. The supporting component 200 includes a supporting base block 201 fixedly connected to the support frame 102. At both ends of the upper surface of the supporting base block 201, a fixing block 202 is respectively fixedly installed. A first through hole 203 is horizontally opened in the center of the fixing block 202. One end of the fixing block 202 close to the center of the supporting base block 201 is fixedly connected to an elastic telescopic sleeve 204. The first through hole 203 is hermetically connected to the elastic telescopic sleeve 204. One end of the elastic telescopic sleeve 204 close to the center of the supporting base block 201 is fixedly connected to a pressing seat 205. The pressing seat 205 can perform a horizontal displacement following the expansion and contraction of the elastic telescopic sleeve 204. One end of the first through hole 203 far from the elastic telescopic sleeve 204 is hermetically connected to an air pump. The air pump is signal-connected to a control system. Adopting the above technical solution, for a medical instrument with a clamping function, such as an orthopedic forceps, with the forceps head facing upwards, the two ends of the bottom forceps handle are respectively abutted against the end faces of the two pressing seats 205. By utilizing the elasticity of the elongation trend of the elastic telescopic sleeves 204 at both ends, the orthopedic forceps can be erected with the forceps head facing upwards to complete the clamping of the orthopedic forceps. In the state without external force, the elastic telescopic sleeves 204 are in a retracted state. After completing the clamping of the orthopedic forceps, the air pump is driven to supply air into the first through hole 203. The air pressure inside the elastic telescopic sleeves 204 increases, the elastic telescopic sleeves 204 elongate, and the two pressing seats 205 slide towards each other and approach, with the distance decreasing, causing the forceps head of the orthopedic forceps to have a tendency to open and the central rotating shaft of the orthopedic forceps to have a tendency to rotate. The process of using gas pressure to push the orthopedic forceps to open is a slow process. After the forceps head of the orthopedic forceps is completely opened, the air supply power of the air pump is slowly reduced, so that the elastic telescopic sleeves 204 retract under the action of the elastic restoring force, and the orthopedic forceps also return to the state where the forceps head is closed. A program is written to control the orthopedic forceps to continuously and repeatedly open and close. During this process, the hot air circulation supply device continuously supplies dry hot air into the housing 101, and the orthopedic forceps can be subjected to air drying and sterilization without dead angles. When the orthopedic forceps are in the open state of the forceps head, the clamping surface of the forceps head can be efficiently air-dried and sterilized. Moreover, in the prior art, for an orthopedic forceps with the forceps head opened to any degree, there will be dead angles with different areas in the area close to the rotating shaft, and the elastic piece in the middle of the forceps-type medical device also has dead angles. In this solution, during the slow opening and closing process of the orthopedic forceps, the dead angles in the area close to the rotating shaft and the intersection area of the elastic pieces of the orthopedic forceps are continuously cyclically exposed, making the air drying and sterilization effect of the orthopedic forceps better and the efficiency higher.

[0025] The supporting component 200 further includes two clamping pieces installed in parallel with each other. The clamping piece includes an outer clamping piece 211 with a dense number of second through holes 212 penetrating through its surface. The bottom end of the outer clamping piece 211 is fixedly connected to the supporting base block 201. With the above technical solution, for the orthopedic forceps held by the extrusion seat 205 and standing upright, the two outer clamping pieces 211 respectively block both sides of the orthopedic forceps, which can improve the stability of the orthopedic forceps during the air-drying and sterilization process and can continuously maintain the standing state with high stability. Compared with the prior art of directly placing medical devices flat in a disinfection cabinet for air-drying and disinfection, the contact area of this solution with medical devices is small, and it can air-dry and disinfect medical devices efficiently and comprehensively.

[0026] An inner clamping piece 214 is fixedly attached to one end of the outer clamping piece 211 close to the other outer clamping piece 211. A number of third through holes 215 equal to the number of the second through holes 212 are penetrated through the inner clamping piece 214. The second through holes 212 and the third through holes 215 correspond one by one, and the axes of the third through holes 215 coincide with the axes of the second through holes 212. A dense number of clamping protrusions 216 are integrally formed on the side wall of the inner clamping piece 214 away from the outer clamping piece 211. The clamping protrusions 216 play a role in flexibly clamping medical devices, improving the stability of medical devices during the air-drying and disinfection process in a point-contact manner, and at the same time having the advantage of a small clamping contact area, which can reduce the air-drying and disinfection dead corners of medical devices and make the air-drying and disinfection effect more thorough.

[0027] A dense number of supporting protrusions 217 are integrally formed on the side wall of the inner clamping piece 214 away from the outer clamping piece 211. The length of the supporting protrusions 217 is greater than the length of the clamping protrusions 216. The supporting protrusions 217 play a role in supporting medical devices and can clamp non-clamping medical devices. The clamping function of the clamping protrusions 216 and the supporting function of the supporting protrusions 217 can clamp non-clamping medical devices above the supporting base block 201.

[0028] The clamping protrusion 216 and the supporting protrusion 217 are both cylindrical structures. The end face diameter of the clamping protrusion 216 is larger than that of the supporting protrusion 217, so that the clamping protrusion 216 has the characteristic of being not easily deformed, and the supporting protrusion 217 has the characteristic of being easily deformed. For medical devices with a clamping function, such as orthopedic forceps, when air-drying and disinfecting, the clamping protrusions 216 on the two inner clamping pieces 214 can be in close contact with the surface of the orthopedic forceps, and can limit the orthopedic forceps in the direction perpendicular to the clamping direction of the extrusion seat 205. During the opening and closing process of the jaws of the orthopedic forceps, the surface of the orthopedic forceps can easily be squeezed through the supporting protrusion 217, and then come into contact with different clamping protrusions 216 in the real-time state, so that the clamping protrusions 216 continuously have a limiting effect on the orthopedic forceps; when the clamping protrusions 216 and the supporting protrusions 217 are actually applied, the clamping effect on the special-shaped medical device 302 is more obvious, such as a grasping forceps. Because the center of gravity of the special-shaped medical device 302 deviates greatly from the forceps handle, it is easy to produce the phenomenon that the end of the forceps handle breaks away from the extrusion seat 205 under the influence of gravity. In this solution, the clamping and supporting functions of the clamping protrusions 216 and the supporting protrusions 217 can be used to reduce the negative effect of the special-shaped medical device 302 tipping caused by gravity, and make the air-drying and disinfection process stable; The inner clamping piece 214, the clamping protrusion 216, and the supporting protrusion 217 are all made of rubber material, and the inner clamping piece 214 is adhesively fixed to the outer clamping piece 211.

[0029] The aperture of the third through hole 215 is larger than that of the second through hole 212, which can facilitate the replacement operation of the inner clamping piece 214 after the supporting protrusion 217 or the clamping protrusion 216 is worn.

[0030] The bottom end of the outer clamping piece 211 is bent to form a bent edge 213, and the bent edge 213 is fixedly connected to the supporting base block 201 by a fastener, realizing the fixing function of the outer clamping piece 211, and having the beneficial effect of facilitating the disassembly and assembly of the outer clamping piece 211.

[0031] The bottom surface of the extrusion seat 205 is slidably connected to the supporting base block 201 by a slide rail and chute 206, which can improve the sliding stability of the extrusion seat 205.

[0032] In another Embodiment 2, the end face diameter of the supporting protrusion 217 is equal to that of the clamping protrusion 216, which can enable the supporting protrusion 217 to have better supporting performance. During the air drying and disinfection of the orthopedic forceps, after the jaws of the orthopedic forceps are fully opened, the position of the rotation shaft of the orthopedic forceps will rise to the highest point. Then, the jaws tend to close, and the two forceps handles tend to open. When the jaws just start to close, the included angle of the forceps handles below the rotation shaft of the orthopedic forceps will be limited and supported by the supporting protrusion 217. The supporting protrusion 217 is stuck in the included angle of the forceps handles. With the supporting function of the supporting protrusions 217 in other areas and the static friction clamping of the clamping protrusions 216, the orthopedic forceps can hover, and the bottom of the forceps handle is separated from the extrusion seat 205. There is no obstruction at the bottom of the forceps handle. At this time, the bottom of the forceps handle can be effectively dried and sterilized thoroughly.

[0033] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed claims.
