Bacterial filtering structure of medical vacuum negative pressure unit

Abstract

This utility model discloses a bacterial filtration structure for a medical vacuum negative pressure unit, relating to the field of medical vacuum negative pressure equipment technology. The utility model includes a base, with several lifting sleeves fixedly connected to the top outer wall of the base. Each of the lifting sleeves has a lifting groove on its inner wall. By incorporating convex shafts, the utility model allows for clockwise rotation of a handle, which in turn drives a worm gear, which in turn drives a worm wheel, which in turn drives a transmission rod. The transmission rod then drives one end of each of the convex shafts to rotate, which in turn drives one end of a connecting rod to move. This connecting rod then drives an extension rod to move upwards, which in turn raises a fixed base. The fixed base then drives several racks to rise, thus achieving a height that can be freely adjusted to accommodate varying heights in different environments and ventilation systems with different elevations, thereby improving the equipment's versatility.

Description

Technical Field

[0001] This utility model belongs to the field of medical vacuum negative pressure machine technology, and in particular relates to a bacterial filtration structure for a medical vacuum negative pressure machine unit. Background Technology

[0002] According to the published patent CN219149589U, a bacterial filtration structure for a medical vacuum negative pressure unit includes a support, a bacterial filtration component, an air inlet pipe, and an air outlet pipe. The bacterial filtration component includes a bacterial filter, a fixed base, and a pressure differential. The air inlet pipe is connected to the air outlet system of the ward, and the air outlet pipe is connected to the vacuum pump. By connecting the air inlet pipe to the air inlet end of the fixed base and the air outlet pipe to the air outlet end, and the air inlet end, bacterial filter, and air outlet end are connected in sequence, the air in the ward needs to enter the air inlet pipe and the air inlet end in sequence, and then enter the bacterial filter through the air inlet end for sterilization. However, the following shortcomings still exist.

[0003] The aforementioned equipment has several drawbacks. The installation height of the equipment is fixed and unchanging, making it difficult to freely adjust the height of the filter. This makes it difficult to adapt and connect with ventilation system ducts with varying heights in different usage environments, resulting in low versatility. Therefore, we propose a bacterial filtration structure for a medical vacuum negative pressure unit. Utility Model Content

[0004] The purpose of this utility model is to provide a bacterial filtration structure for a medical vacuum negative pressure unit. Through a lifting mechanism and a fixing mechanism, it solves the problems of fixed installation height, lack of flexibility in adjusting the height of the filter, difficulty in adapting to different usage environments and ventilation system ducts with height differences, and low versatility of the equipment.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a bacterial filtration structure for a medical vacuum negative pressure unit, including a base, a plurality of lifting sleeves fixedly connected to the top outer wall of the base, a lifting groove being provided on the inner wall of each of the lifting sleeves, and a lifting mechanism being provided on the top outer wall of the base.

[0007] The lifting mechanism includes a worm gear seat, the outer wall of which is fixedly connected to the top outer wall of the base. A worm is rotatably connected to the inner wall of the worm gear seat, and a throttle is fixedly connected to the outer wall of the worm. A transmission rod is rotatably connected to the inner wall of several lifting sleeves. A worm wheel is fixedly connected to the outer wall of the transmission rod, and the outer wall of the worm wheel meshes with the outer wall of the worm. Several convex shafts are fixedly connected to the outer wall of the transmission rod. A connecting rod is rotatably connected to the inner wall of each of the convex shafts. An extension rod is rotatably connected to the inner wall of the connecting rod, and the outer wall of the extension rod is slidably connected to the inner wall of the lifting groove.

[0008] Furthermore, a fixing mechanism is provided on the top outer wall of the extension rod. The fixing mechanism includes a fixing seat, the bottom outer wall of the fixing seat is fixedly connected to the top outer wall of the extension rod, and a worm gear is rotatably connected to the inner wall of the fixing seat.

[0009] Furthermore, a throttle two is fixedly connected to the outer wall of the worm gear two, a worm wheel two is rotatably connected to the inner wall of the fixed seat, and a gear is fixedly connected to the top outer wall of the worm wheel two.

[0010] Furthermore, the inner wall of the fixing base is provided with a plurality of sliding grooves, and a rack is slidably connected to the inner wall of each of the plurality of sliding grooves, and a fixing clamp is fixedly connected to the top outer wall of the rack.

[0011] Furthermore, the outer wall of the fixing clamp on the right side is fixedly connected with several fixing pins, and the inner wall of the fixing clamp on the left side is provided with several pin grooves.

[0012] Furthermore, a fixing block is slidably connected to the outer wall of the fixing pin, the fixing pin passes through the fixing block to the outer wall, and fixing tubes are fixedly connected to the outer walls of several fixing blocks.

[0013] Furthermore, filters are fixedly connected to the outer walls of several of the fixed tubes, and an air inlet pipe is fixedly connected to the inner wall of the fixed tube on the left side.

[0014] Furthermore, a filter element is fixedly connected to the outer wall of the air inlet pipe, and an air outlet pipe is fixedly connected to the outer wall of the fixed pipe on the right side.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a convex shaft, allows the handle to be rotated clockwise. The handle drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the transmission rod to rotate, the transmission rod drives one end of several convex shafts to rotate, and each of the convex shafts drives one end of the connecting rod to move. The connecting rod drives the extension rod to move upward, the extension rod drives the fixed seat to rise, and the fixed seat drives several racks to rise. This achieves the goal of breaking away from a fixed installation height and allowing the height of the filter to be freely adjusted to adapt to different usage environments and ventilation system ducts with height differences, thus improving the versatility of the equipment.

[0017] 2. This utility model incorporates a fixing clamp. To separate and disassemble the filter, several handles can be rotated counterclockwise. Each handle rotates a worm gear, which in turn rotates a worm wheel, which in turn rotates a gear. This gear then displaces several racks, which in turn displace the fixing clamp. The fixing clamp on the right side disengages several fixing pins from their slots and the fixing block, thus removing the fixing block. The entire filter, along with several fixing tubes, can then be easily removed upwards from the fixing clamp. This allows for quick and convenient disassembly and separation of the filter, facilitating its subsequent individual transfer for maintenance.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A lifting mechanism 2 is provided on the top outer wall of the base 1.

[0030] The lifting mechanism 2 includes a worm gear seat 201, the outer wall of which is fixedly connected to the top outer wall of the base 1. A worm 202 is rotatably connected to the inner wall of the worm gear seat 201. The worm gear seat 201 primarily limits the rotation of the worm 202, allowing it to rotate only at a fixed position within the worm gear seat 201. A handle 203 is fixedly connected to the outer wall of the worm 202. A transmission rod 204 is rotatably connected to the inner walls of several lifting sleeves 101. A worm wheel 205 is fixedly connected to the outer wall of the transmission rod 204, and the outer wall of the worm wheel 205 meshes with the outer wall of the worm 202. The rod 202 mainly serves to transmit kinetic energy to the worm gear 205. When the worm 202 rotates, it will drive the worm gear 205 to rotate simultaneously. Several convex shafts 206 are fixedly connected to the outer wall of the transmission rod 204. The inner walls of the several convex shafts 206 are rotatably connected to the connecting shafts 207. The inner walls of the connecting shafts 207 are rotatably connected to the extension rods 208. The transmission rod 204 mainly serves to fix and limit the several convex shafts 206.

The outer wall of the extension rod 208 is slidably connected to the inner wall of the lifting groove 102.

[0031] A fixing mechanism 3 is provided on the top outer wall of the extension rod 208. The fixing mechanism 3 includes a fixing seat 301. The bottom outer wall of the fixing seat 301 is fixedly connected to the top outer wall of the extension rod 208. The extension rod 208 mainly serves to fix and limit the fixing seat 301. The fixing seat 301 can only be fixed in one position on the extension rod 208. A worm gear 302 is rotatably connected to the inner wall of the fixing seat 301. A throttle 303 is fixedly connected to the outer wall of the worm gear 302. A worm wheel 304 is rotatably connected to the inner wall of the fixing seat 301. The top of the worm wheel 304... A gear 305 is fixedly connected to the outer wall of the part. The fixed seat 301 mainly serves to limit the rotation of the worm gear 304. The worm gear 304 can only rotate in a fixed position within the fixed seat 301. Several sliding grooves 306 are provided on the inner wall of the fixed seat 301. A rack 307 is slidably connected to the inner wall of each of the sliding grooves 306. A fixing clamp 308 is fixedly connected to the top outer wall of the rack 307. The sliding grooves 306 mainly serve to limit the sliding of the rack 307. The rack 307 can slide at a fixed angle within the sliding grooves 306.

[0032] The right-side clamp 308 has several fixing pins 309 fixedly connected to its outer wall. The left-side clamp 308 has several pin grooves 310 on its inner wall. Fixing blocks 311 are slidably connected to the outer walls of the fixing pins 309. The right-side clamp 308 mainly serves to fix and limit the fixing pins 309. When the clamp 308 moves, it will cause the fixing pins 309 to move together. The fixing pins 309 pass through the fixing blocks 311 to the outer wall. Fixing tubes 312 are fixedly connected to the outer walls of the fixing blocks 311. A filter 313 is fixedly connected to the outer wall of the filter. The filter 313 mainly serves to fix and limit the positions of several fixed pipes 312. The fixed pipes 312 can only be fixed in the position on the filter 313. An air inlet pipe 314 is fixedly connected to the inner wall of the fixed pipe 312 on the left side. A filter element 315 is fixedly connected to the outer wall of the fixed pipe 314. An air outlet pipe 316 is fixedly connected to the outer wall of the fixed pipe 312 on the right side. The air inlet pipe 314 mainly serves to fix and limit the positions of the filter element 315. The filter element 315 can only be fixed in the position on the air inlet pipe 314.

[0033] One specific application of this embodiment is:

[0034] When staff need to use the equipment, the inlet duct 314 and outlet duct 316 can be connected to the ventilation system. Unfiltered air will enter the filter element 315 through the inlet duct 314 for filtration to remove bacteria. The filtered air will leak out from the filter element 315 and fill the filter 313, then flow through the right-side fixing block 311 to the outlet duct 316 and be discharged. If it is necessary to raise the height of the filter 313 to be level with the ventilation system duct and connect it, the handle 203 can be turned clockwise. The handle 203 will drive the worm gear 202 to rotate, which will drive the worm wheel 205 to rotate. The worm wheel 205 will drive the transmission rod 204 to rotate, which will drive one end of several cam shafts 206 to rotate. Each of the cam shafts 206 will drive one end of the connecting rod 207 to move. The connecting rod 207 will drive the extension rod 208 to move upward, which will drive the fixed seat 301 to rise. The fixed seat 301 will then drive... Several racks 307 rise, which in turn drives the fixing clamps 308 to rise. The fixing clamps 308 then drive the fixing tubes 312 to rise, and the fixing tubes 312 then drive the filter 313 to rise to the same horizontal level as the ventilation system duct. If the filter 313 needs to be separated and disassembled, several handles 303 can be turned counterclockwise. These handles 303 will drive the worm gear 302 to rotate, which in turn drives the worm wheel 304 to rotate. The worm wheel 304 will drive the gear 305 to rotate, which will then drive several racks 307 to move. These racks 307 will then drive the fixing clamps 308 to move. The fixing clamps 308 on the right side will then drive several fixing pins 309 to disengage from the pin slots 310 and the fixing block 311, thus no longer securing the fixing block 311. Then, the filter 313, along with several fixing tubes 312, can be directly removed upwards from the fixing clamps 308 for separation.
