Description

Technical Field

[0001] The invention belongs to the technical field of air supply, in particular to an air supply device for an operating room. Background Art

[0002] The operating room is a place for patients to undergo surgery and rescue, and is an important technical department of the hospital. During the operation, in order to prevent incision infection and ensure the success rate of the operation, four necessary conditions of the operating room, including the air in the operating room, the items required for the operation, the fingers of doctors and nurses, and the skin of patients, are required to prevent the surgical incision from being infected by bacteria. The operating room should be equipped with corresponding air supply devices according to different levels of requirements to ensure the cleanliness and sterility of the surgical site. Traditional unpowered roof fans use the flow of air to drive the fan to rotate slowly, guide the air into the air supply duct, and then discharge it into the operating room after purification and filtration components.

[0003] A patent application with publication number CN116481110B discloses a modular fresh air supply device for an operating room. When the filter needs to be cleaned, the patent moves the shaft and the cleaning hood away from the purification room along the horizontal section one, then moves downward along the vertical section one, and then approaches the purification room along the horizontal section two. When the moving shaft reaches the end of the horizontal section two, the cleaning hood is pressed against the end face of the filter, and then the fan two is turned on. Part of the air that passes through the filter and enters the air inlet end of the purification room flows along the cleaning hood, the hose, and the fan two to the filter box. Under the flushing of this part of air, impurities on the filter are separated from the filter, and the rest of the air enters the purification room normally for purification. When the cleaning hood on one side is cleaned, the other cleaning hood can be operated to clean the other part of the filter, which will not affect the work of the purification room, thereby achieving non-stop cleaning.

[0004] There are still some problems in the actual use of the above-mentioned prior art. Since the air supply device draws external air into the air supply duct and uses a filter plate to filter the dust and lint in the air before discharging it into the operating room, however, during the long-term air supply process, a large amount of dust, lint and spider webs will adhere to the filter plate, causing the filter plate to be blocked. The accumulation of a large amount of dust, lint and spider webs will breed bacteria, and when the air flows through the filter plate, the bacteria grown on the filter plate will be brought into the operating room, thereby affecting the sterile environment in the operating room.

[0037] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1: Please refer to Figure 1-12 , the present invention provides a technical solution:

[0039] An operating room air supply device comprises a mounting cover 1, an air supply duct 3 is welded and fixedly connected to one side of the mounting cover 1, a filter screen plate 4 is slidably connected to the upper end of the air supply duct 3, a handle 5 is fixedly connected to the upper end of the filter screen plate 4, two support rods 16 are symmetrically fixedly connected to the two walls of the inner cavity of the air supply duct 3, a support sleeve 18 is fixedly connected between the two support rods 16, and a cleaning drive assembly is rotatably connected to the inner cavity of the support sleeve 18;

[0040] The cleaning drive assembly includes a transmission shaft 19 rotating in the inner cavity of the support sleeve 18, one end of the transmission shaft 19 is fixedly connected to a rotating rod 20, a T-shaped slide bar 25 is slidably connected to the inner cavity of the rotating rod 20, one end of the T-shaped slide bar 25 is internally rotatably connected to a limited slider 30, the outer surface of the limited slider 30 is slidably connected to a cleaning rod 26, and the cleaning rod 26 is slidably connected in the inner cavity of the air supply duct 3, and a brush 11 is evenly arranged on one end surface of the cleaning rod 26;

[0041] One end of the transmission shaft 19 is fixedly connected with a non-powered hood 6 , and the non-powered hood 6 is rotatably connected to the mounting cover 1 , and a collecting port 9 is opened at the lower end of the air supply duct 3 .

[0042] Specifically, in the prior art, the air supply device draws external air into the air supply duct, and uses the filter screen to filter the dust and fluff in the air before discharging it into the operating room. However, during the long-term air supply process, a large amount of dust, fluff and spider webs will adhere to the filter screen, causing the filter screen to be blocked. The accumulation of a large amount of dust, fluff and spider webs will breed bacteria, and when the air flows through the filter screen, the bacteria grown on the filter screen will be brought into the operating room, thereby affecting the sterile environment in the operating room.

[0043] In the present invention, when air is supplied to the operating room, the wind blows the unpowered hood 6 to rotate, and the unpowered hood 6 drives the transmission shaft 19 to rotate, and at the same time the unpowered hood 6 draws external air into the air supply duct 3, and then uses the filter screen 4 to filter the incoming air, and the transmission shaft 19 will drive the rotating rod 20 to rotate during the rotation process, and during the rotation process of the rotating rod 20, it will drive the T-shaped sliding bar 25 to rotate, and then drive the limiting slider 30 to rotate synchronously, and during the rotation process of the limiting slider 30, it will slide in the inner cavity of the cleaning rod 26, and then drive the cleaning rod 26 to reciprocate in the inner cavity of the air supply duct 3, and one end surface of the cleaning rod 26 is evenly provided with hair. The brush is used to clean the filter screen 4 during the reciprocating translation of the cleaning rod 26, so that the dust, lint and spider webs attached to the filter screen plate 4 are cleaned and scraped off, avoiding a large amount of dust, lint and spider webs attached to the filter screen plate 4, causing blockage of the filter screen plate 4 and affecting the air supply efficiency, thereby solving the problem that a large amount of dust, lint and spider webs will adhere to the filter screen plate during the long-term air supply process of the existing operating room air supply device, causing the filter screen plate to be blocked, and the accumulation of a large amount of dust, lint and spider webs will breed bacteria, and when the air flows through the filter screen plate, the bacteria grown on the filter screen plate will be brought into the operating room, thereby affecting the sterile environment in the operating room.

[0044] like Figure 1 , Figure 3 and Fig.12 As shown, a mounting groove 15 is provided on one side of the mounting cover 1 , and a protective grid 2 is installed in the inner cavity of the mounting groove 15 to prevent birds from entering the air supply duct 3 .

[0045] Specifically, when air is supplied to the operating room, the protective grid 2 is installed in the inner cavity of the mounting groove 15 by means of bolts to prevent birds from entering the air supply duct 3 to build nests when the unpowered wind hood 6 draws air into the air supply duct 3. Birds live in the air supply duct 3 for a long time, and their feces will breed bacteria. The bacteria will enter the operating room during the air supply process, affecting the sterile environment in the operating room.

[0046] like Figure 2 and Figure 4 As shown, a mounting cover plate 7 is installed on one side of the air supply duct 3 by means of bolts 12, an air supply port 8 is opened on one side of the mounting cover plate 7, and a filter screen cover is installed in the inner cavity of the air supply port 8, and the filter screen cover is located on one side of the inner cavity of the air supply duct 3 and is fixed with an activated carbon filter block 14.

[0047] Specifically, when the air supply duct 3 is installed, the filter screen cover is installed in the inner cavity of the air supply port 8, and then the cover plate 7 is installed to drive the activated carbon filter block 14 to be inserted into the inner cavity of the air supply duct 3, and the cover plate 7 and the air supply duct 3 are installed and fixed by bolts. After the air is filtered by the filter screen plate 4, the activated carbon filter block 14 can be used to remove harmful gases and odors in the air, reduce the PM2.5 concentration, and effectively adsorb organic pollutants in the air, thereby improving the quality of air discharged into the operating room.

[0048] like Figure 5 As shown, a receiving groove 23 is provided inside the rotating rod 20 , a spring 24 is fixedly connected to the bottom of the inner cavity of the receiving groove 23 , and one end of the spring 24 is fixedly connected to a T-shaped sliding rod 25 .

[0049] Specifically, in the process of driving the rotating rod 20 to rotate, the rotating rod 20 will drive the T-shaped slide bar 25 to rotate synchronously, and at the same time, the T-shaped slide bar 25 drives the cleaning rod 26 to reciprocate. After the cleaning rod 26 moves to the side wall of the air supply duct 3, the cleaning rod 26 cannot move. At this time, the rotating rod 20 drives the T-shaped slide bar 25 to rotate, and the T-shaped slide bar 25 will slide into the inner cavity of the storage groove 23 and squeeze the spring 24 in the inner cavity of the storage groove 23, so that the T-shaped slide bar 25 can adaptively adjust the length according to the inner cavity wall of the air supply duct 3, so that the T-shaped slide bar 25 can drive the cleaning rod 26 to reciprocate in the inner cavity of the air supply duct 3, and then clean the dust from the filter screen 4.

[0050] like Figure 6 , Figure 5 and Fig.11 As shown, a T-slot 13 is provided on the upper wall of the inner cavity of the air supply duct 3, and a T-slot slider 29 is slidably connected to the inner cavity of the T-slot 13, the lower end of the T-slot slider 29 is fixedly connected to the cleaning rod 26, and a T-slot 27 is provided on one side of the cleaning rod 26, and the T-slot 27 is slidably connected to the limit slider 30.

[0051] Specifically, when the rotating rod 20 drives the T-shaped slide bar 25 to rotate, the T-shaped slide bar 25 will drive the limit slider 30 to rotate synchronously, and at the same time, the limit slider 30 slides in the inner cavity of the T-shaped slide groove 27, and drives the cleaning rod 26 to reciprocate in the inner cavity of the air supply duct 3. During the reciprocating translation process, the cleaning rod 26 will drive the T-shaped slide bar 29 to move synchronously, and at the same time, the T-shaped slide bar 29 slides in the inner cavity of the T-shaped groove 13, thereby ensuring the smooth movement of the cleaning rod 26, and Figure 7 As shown, the limit slider 30 is configured as a long strip, and can only slide up and down in the inner cavity of the T-shaped slide groove 27, thereby preventing the limit slider 30 from rotating during the sliding process in the inner cavity of the T-shaped slide groove 27, thereby improving the stability of the cleaning rod 26 during movement.

[0052] Embodiment 2: Figures 1 to 12 As shown in Comparative Example 1, another embodiment of the present invention is:

[0053] like Figure 3 and Fig.11 As shown, the lower end of the cleaning rod 26 is slidably connected in the inner cavity of the collecting port 9, and automatic closing components are arranged on both sides of the inner cavity of the collecting port 9. The automatic closing components include a sealing baffle 91 fixedly connected to the inner cavity of the collecting port 9, and slide grooves 92 are provided at both ends of the sealing baffle 91. A micro spring 93 is fixedly connected to the bottom of the inner cavity of the slide groove 92, and a slide plate 94 is fixedly connected to one end of the micro spring 93, and a plurality of elastic members 95 are evenly fixedly connected to one side of the upper end surface of the slide plate 94.

[0054] Specifically, when the cleaning rod 26 is driven to do reciprocating translation, the lower end of the cleaning rod 26 will slide in the inner cavity of the collecting port 9. At the same time, the cleaning rod 26 will push the elastic member 95 to move synchronously during the translation process. At the same time, the elastic member 95 drives the slide plate 94 to slide into the inner cavity of the slide groove 92 and squeeze the micro spring 93 in the inner cavity of the slide groove 92, thereby opening the collecting port 9, and then the dust, fluff and spider webs cleaned by the cleaning rod 26 with the brush are scraped off and discharged into the inner cavity of the collecting port 9. In the process of continuous movement of the cleaning rod 26 driven by the limiting slider 30, the elastic member 95 is deformed by the moving extrusion force, thereby disengaging from the abutment with the lower end of the cleaning rod 26. At the same time, the micro spring 9 The sliding plate 94 is pushed back by the spring 94, and the sliding plate 94 slides out of the sliding groove 92 to seal the collecting port 9, so as to prevent the air from forming a vortex wind in the collecting port 9 during the air supply process due to the failure to seal the collecting port 9, and blowing out the dust, fluff and spider webs collected in the inner cavity of the collecting port 9, causing the dust, fluff and spider webs to attach to the filter screen plate 4 again. This solves the problem that after the existing air supply device for the operating room cleans and collects the dust, fluff and spider webs, it is inconvenient to seal the collecting port, resulting in the formation of a vortex wind in the collecting port during the air supply process, blowing out the dust, fluff and spider webs in the inner cavity of the collecting port, and affecting the cleaning effect of the dust, fluff and spider webs.

[0055] like Figures 6 to 8 As shown, the limiting slider 30 is located at one end of the cleaning rod 26, and a cleaning brush 28 is fixedly connected to the brush. A plurality of steel needles 32 are evenly fixedly connected to the lower end surface of the cleaning brush 28.

[0056] Specifically, after the cleaning rod 26 moves to one side wall of the air supply duct 3, the cleaning rod 26 cannot move, and at this time the rotating rod 20 drives the T-shaped slide bar 25 to rotate, and the T-shaped slide bar 25 will slide into the inner cavity of the rotating rod 20, and at the same time, the T-shaped slide bar 25 drives the limiting slider 30 to slide downward in the inner cavity of the T-shaped slide groove 27, and the limiting slider 30 drives the cleaning brush 28 to move synchronously, and the lower end surface of the cleaning brush 28 is evenly provided with a plurality of steel needles 32, and then the steel needles 32 can be used to comb the brush of the cleaning rod 26, and at the same time When cleaning the filter screen plate 4, the dust, fluff and spider webs generated by the brush are combed onto the steel needle 32 to avoid a large amount of dust, fluff and spider webs being entangled in the brush, which affects the cleaning effect of the brush on the filter screen plate 4, thereby solving the problem that when the cleaning rod of the existing operating room air supply device uses a brush to clean the dust, fluff and spider webs on the filter screen plate, a large amount of dust, fluff and spider webs will be entangled in the brush. If the dust, fluff and spider webs in the brush are not combed out, the cleaning effect of the brush on the filter screen plate will be affected.

[0057] like Figures 6 to 8 As shown, a groove 33 is opened inside the lower end surface of the cleaning brush 28, and a tension spring 34 is fixedly connected to the bottom of the inner cavity of the groove 33. One end of the tension spring 34 is fixedly connected to the limiting plug 21, and the lower end of the limiting plug 21 is fixedly connected to the fluff cleaning plate 31, and the fluff cleaning plate 31 is slidably connected to the steel needle 32.

[0058] Specifically, after the limiting slider 30 drives the cleaning brush 28 to move to the bottom of the cleaning rod 26, the limiting slider 30 will drive the cleaning rod 26 to move toward the other side wall of the inner cavity of the air supply duct 3 as the rotating rod 20 rotates. During the process of the limiting slider 30 driving the cleaning rod 26 to move, the fluff cleaning plate 31 will contact the lower end surface of the inclined fixing block 35. As the limiting slider 30 continues to move, the fluff cleaning plate 31 will cooperate with the inclined surface of the inclined fixing block 35 to slide out of the groove 33, and at the same time pull the tension spring 34 to move downward. At this time, the cleaning rod 26 The elastic member 95 will abut against the sliding plate 94 to open the collecting port 9, and the fluff cleaning plate 31 will slide on the outside of the steel needle 32, pushing off the dust, fluff and spider webs combed on the outside of the steel needle 32, and dropping them into the inner cavity of the collecting port 9 for storage, thereby solving the problem that when the cleaning rod of the existing operating room air supply device uses a brush to clean the dust, fluff and spider webs on the filter screen, a large amount of dust, fluff and spider webs will be entangled in the brush. If the dust, fluff and spider webs in the brush are not combed out, the cleaning effect of the brush on the filter screen will be affected.

[0059] like Figure 3 and Fig. 9 As shown, two air guide plates 22 are symmetrically fixed to the inner wall of the air supply duct 3, and two inclined fixing blocks 35 are symmetrically arranged on one side of the air guide plate 22 located on the lower wall of the inner cavity of the air supply duct 3. The inclined fixing blocks 35 are used to move the fluff cleaning plate 31.

[0060] Specifically, during the process of supplying air into the operating room, the direction of the air supply is guided by using two air guide plates 22 to avoid the formation of vortex wind in the collecting port 9 during the air supply process, so as to blow out the dust, fluff and spider webs collected in the inner cavity of the collecting port 9, causing dust to appear in the air supply duct 3, thereby improving the cleanliness of the air supply device.

[0061] like Figure 3 and Fig.10 As shown, one end of the transmission shaft 19 is fixedly connected to the non-powered hood 6, and one side of the mounting cover 1 is provided with mounting holes 17 at four corners.

[0062] Specifically, when air needs to be supplied to the operating room, the wind blows the unpowered wind hood 6 to rotate, and the unpowered wind hood 6 drives the transmission shaft 19 to rotate. During the rotation of the transmission shaft 19, it will drive the cleaning drive component to operate, and the cleaning drive component will clean the air dust, fluff and cobwebs on the filter plate 4. The air will be discharged into the activated carbon filter block 14 for filtration and purification, and then discharged into the operating room through the air supply port 8, thereby improving the air supply efficiency. In addition, the motor is installed outside the air supply duct, which is also convenient for maintenance of the air supply device.

[0063] The working principle is that when air is supplied to the operating room, the wind blows the unpowered hood 6 to rotate, and the unpowered hood 6 drives the transmission shaft 19 to rotate, and at the same time the unpowered hood 6 draws external air into the air supply duct 3, and then uses the filter screen plate 4 to filter the incoming air, and the transmission shaft 19 will drive the rotating rod 20 to rotate during the rotation process, and during the rotation process of the rotating rod 20, it will drive the T-shaped sliding bar 25 to rotate, and then drive the limiting slider 30 to rotate synchronously, and during the rotation process of the limiting slider 30, it will slide in the inner cavity of the cleaning rod 26, and then drive the cleaning rod 26 to reciprocate in the inner cavity of the air supply duct 3, and one end surface of the cleaning rod 26 is evenly provided with a brush, so that during the reciprocating translation of the cleaning rod 26, the brush is used to clean the filter screen plate 4, so that the dust, fluff and spider attached to the filter screen plate 4 are cleaned and scraped off, so as to avoid a large amount of dust, fluff and spider attached to the filter screen plate 4, causing the filter screen plate 4 to be blocked and affecting the air supply efficiency;

[0064] When the cleaning rod 26 is driven to do reciprocating translation, the lower end of the cleaning rod 26 will slide in the inner cavity of the collecting port 9. At the same time, during the translation process of the cleaning rod 26, the elastic member 95 will be pushed to move synchronously. At the same time, the elastic member 95 drives the slide plate 94 to slide into the inner cavity of the slide groove 92 and squeeze the micro spring 93 in the inner cavity of the slide groove 92, so as to open the collecting port 9, and then the dust, fluff and spider webs cleaned by the cleaning rod 26 with the brush are scraped off and discharged into the inner cavity of the collecting port 9. In the process of continuous movement of the cleaning rod 26 driven by the limiting slider 30, the elastic member 95 is deformed by the moving extrusion force, so as to be out of contact with the lower end of the cleaning rod 26. At the same time, the micro spring 93 rebounds and pushes the slide plate 94, so that the slide plate 94 slides out of the slide groove 92 to seal the collecting port 9.

[0065] After the limiting slider 30 drives the cleaning brush 28 to move to the bottom of the cleaning rod 26, the limiting slider 30 will drive the cleaning rod 26 to move toward the other side wall of the inner cavity of the air supply duct 3 as the rotating rod 20 rotates. During the process of the limiting slider 30 driving the cleaning rod 26 to move, the fluff cleaning plate 31 will contact the lower end surface of the inclined fixing block 35. As the limiting slider 30 continues to move, the fluff cleaning plate 31 will cooperate with the inclined surface of the inclined fixing block 35 to slide out of the groove 33, and at the same time pull the tension spring 34 to move downward, and at this time the cleaning rod 26 will The abutting elastic member 95 pushes the slide plate 94 to open the collecting port 9, and the fluff cleaning plate 31 will slide on the outside of the steel needle 32, pushing off the dust, fluff and spider webs combed out of the outside of the steel needle 32, and dropping them into the inner cavity of the collecting port 9 for storage, thereby solving the problem that when the cleaning rod of the existing operating room air supply device uses a brush to clean the dust, fluff and spider webs on the filter screen, a large amount of dust, fluff and spider webs will be entangled in the brush. If the dust, fluff and spider webs in the brush are not combed out, the cleaning effect of the brush on the filter screen will be affected.
