Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of bed unit disinfection equipment, and specifically relates to a movable bed unit disinfection device. Background Art
[0002] In places with a large flow of people such as hospitals and nursing homes, different users may carry various pathogens. Therefore, when a patient is admitted to a ward or an elderly person enters a nursing room, if the bed unit has not been strictly and effectively disinfected, these latent pathogens can easily spread inadvertently through media such as bed sheets, quilt covers, and pillowcases, thereby increasing the risk of infection.
[0003] Currently, after the operator usually removes and washes fabrics such as bed sheets, quilt covers, and pillowcases on the bed, the operator will also use a transparent plastic bag to cover the quilt core, pillow core and other fabrics and then seal the plastic bag. By the operator making two holes in the transparent plastic bag, and then the operator connects two connecting pipes (one is an air delivery pipe and the other is an air extraction pipe) on the ozone disinfection machine to the inside of the plastic bag through the two holes respectively. The ozone disinfection machine intermittently delivers ozone into the plastic bag and discharges waste gas to disinfect the quilt core, pillow core and other fabrics inside the plastic bag. However, connecting the two connecting pipes on the ozone disinfection machine to the inside of the plastic bag through the holes made in the plastic bag easily causes ozone leakage inside the plastic bag, so that the ozone concentration in the disinfection space is difficult to maintain at an effective disinfection level, resulting in the quilt core, pillow core and other fabrics not being fully and thoroughly disinfected, thereby reducing the disinfection effect. At the same time, the ozone leaking to the outside may also cause irritation to the operator.
[0004] Therefore, to solve the above problems, a movable bed unit disinfection device is proposed. Summary of the Invention
[0005] To solve the problems raised in the above background art, the present invention provides a movable bed unit disinfection device, which solves the problem that ozone leakage may occur and the disinfection effect may be reduced by connecting two connecting pipes on an ozone disinfection machine to the inside of a plastic bag through holes made in the plastic bag.
[0006] To achieve the above object, the present invention provides the following technical solution: A movable bed unit disinfection device includes a communication component, and further includes: a connection component installed at the bottom of the communication component; a telescopic rod component arranged in a circumferential array on the communication component; an adjustment component arranged at the top of the telescopic rod component for controlling the extension or contraction of the telescopic rod component. The connected component includes an outer tube and an inner tube movably sleeved inside it. A first through groove and a second through groove are formed in the outer tube. A first disc is movably sleeved outside the outer tube. The inner wall of the first disc passes through the first through groove and is fixedly connected to the top of the inner tube. A second disc is fixedly sleeved outside the outer tube. A first through hole is formed at the bottom of the outer tube. When the inner tube moves upward, the outer wall of its top can block the first through groove. The connection component includes a connection ring movably sleeved outside the outer tube. A rubber sleeve and a corrugated pipe are respectively fixedly connected to the top and bottom of the connection ring. The top end of the rubber sleeve and the bottom end of the corrugated pipe are both fixedly connected to the outer tube. The telescopic rod component includes an outer cylinder fixedly connected to the top of the second disc, and the bottom of the outer cylinder communicates with the outside. A piston rod is movably connected inside the outer cylinder. The top end of the piston rod extends outside the outer cylinder and is fixedly connected to the first disc. The rod part of the piston rod is a hollow rod, and a third through hole is formed at the bottom of the hollow rod. A tension spring is fixedly connected to the top of the inner cavity of the outer cylinder. The bottom of the tension spring is fixedly connected to the piston part of the piston rod. The cavity where the tension spring is located is a hollow cavity, and the hollow cavity communicates with the hollow rod through the third through hole. The adjustment component includes an annular ring movably connected to the top end of the piston rod. A fourth through hole is formed in the annular ring. The cavity of the piston rod can communicate with the outside through the fourth through hole. An air bag for contacting the outer wall of the pipeline on the ozone disinfection machine is arranged at the top of the outer tube.
[0007] Preferably, a top rod is fixedly connected to the bottom of the inner tube. The bottom of the top rod is conical and extends below the outer tube.
[0008] Preferably, a guide ring located inside the rubber sleeve is fixedly connected to the outside of the outer tube.
[0009] Preferably, for the part of the outer tube located inside the rubber sleeve, its outer wall is frustum-shaped and expands upward.
[0010] Preferably, the wall thickness of the upper middle part of the rubber sleeve is smaller than that of the lower middle part.
[0011] Preferably, the adjustment component further includes arc-shaped positioning blocks fixedly connected to the annular ring in a circumferential array. When the concave surface on the arc-shaped positioning block contacts the top of the piston rod, the cavity of the piston rod can be completely communicated with the fourth through hole.
[0012] Preferably, a hose is fixedly connected to the top of the piston rod. The top end of the piston rod can communicate with the hose through the fourth through hole. A second through hole is formed at the top of the outer tube. The hose communicates with the air bag through the second through hole.
[0013] Preferably, positioning components for detecting whether the bottom of the second disc contacts the plastic film are arranged in a circumferential array at the bottom of the second disc.
[0014] Preferably, the positioning assembly comprises a rotating rod hinged to the bottom of the second disc body, an elastic block is elastically connected to the inside of the second disc body, a clamping block is provided on the inner tube, and the elastic block is subjected to its own elastic force so that one end thereof abuts against the hinge of the rotating rod, and the outer part of the hinge of the rotating rod is cam-shaped; A limiting rod is fixedly connected to the bottom of the piston rod. The bottom of the limiting rod is conical and initially extends to the bottom of the outer tube and passes through the second disc body. The limiting rod is provided with a slot that is initially engaged with the clamping block. When the rotating rod rotates to the inside of the second disc body, the top end of the rotating rod can squeeze the elastic block and make the clamping block escape from the clamping slot.
[0015] Compared with the prior art, the present invention has the following beneficial effects: The above scheme is that the operator penetrates the outer tube through the plastic bag until the outer wall of the plastic bag contacts the bottom of the second disc body, and then rotates the annular ring so that the top of the piston rod is connected to the fourth through hole. At this time, under the action of the tension of the tension spring, the piston rod will be driven upward to discharge the gas in the cavity through the third through hole and the piston rod cavity. The upward movement of the piston rod will also drive the inner tube and the connecting ring upward through the first disc body. At this time, the top of the inner tube is sealed to a place in the through groove, and the upward movement of the bottom of the rubber sleeve will cause the upper part of the rubber sleeve to deform. At this time, the top of the rubber sleeve will squeeze the edge of the hole drilled by the outer tube in the plastic bag. At this time, the second disc body and the rubber sleeve squeeze the plastic bag from the outside and the inside respectively, so as to ensure the sealing between the outer wall of the outer tube and the plastic bag after the outer wall of the outer tube passes through the plastic bag. Then, the pipeline on the ozone disinfector passes through the outer tube and contacts with the airbag and enters the inner tube to complete the connection, thereby solving the problem that the two connecting pipes on the ozone disinfector are connected to the inside of the plastic bag through the holes poked in the plastic bag, which may cause ozone leakage; The above scheme pulls the bag body with the edge of the hole on the plastic bag and makes it in a taut state before the second disc body contacts the plastic bag, so that the rotating rod is squeezed by the plastic bag and rotates and retracts into the second disc body. At this time, the rotation of the second disc body around the axis causes the top of the rotating rod to push the elastic block to move, so that the clamping block releases the clamping connection with the clamping groove, so that the inner edge of the hole is located above the rubber sleeve, and the operator can control the adjustment component to make the telescopic rod component work, so as to ensure that the subsequent device can effectively seal the connection between the outer tube and the plastic bag hole; In the above scheme, when the piston rod moves upward, the gas inside the cavity will enter the cavity of the adjustment component through the piston rod, the airbag and the second through hole. At this time, the airbag will expand and squeeze the pipe on the ozone sterilizer inserted therein, further ensuring the sealing between the pipe on the ozone sterilizer and the device.

[0018] 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.
[0019] As Figures 1 to 9 shown, the present invention provides a movable bed unit disinfection device, including a connection component 1, and further including: a connection component 2, which is installed at the bottom of the connection component 1; a telescopic rod component 3, which is arranged in a circumferential array on the connection component 1; an adjustment component 5, which is arranged at the top of the telescopic rod component 3 for controlling the elongation or contraction of the telescopic rod component 3; The connecting component 1 includes an outer tube 11 and an inner tube 12 movably sleeved inside it. A first through groove 111 and a second through groove 112 are formed on the outer tube 11. A first disk body 13 is movably sleeved outside the outer tube 11. The inner wall of the first disk body 13 passes through the first through groove 111 and is fixedly connected to the top of the inner tube 12. A second disk body 14 is fixedly sleeved outside the outer tube 11. A first through hole 113 is formed at the bottom of the outer tube 11. When the inner tube 12 moves upward, the outer wall of its top can block the first through groove 111. The connecting component 2 includes a connecting ring 21 movably sleeved outside the outer tube 11. A rubber sleeve 22 and a corrugated pipe 23 are respectively fixedly connected to the top and bottom of the connecting ring 21. The top end of the rubber sleeve 22 and the bottom end of the corrugated pipe 23 are both fixedly connected to the outer tube 11. The telescopic rod component 3 includes an outer cylinder 31 fixedly connected to the top of the second disk body 14 and the bottom of the outer cylinder 31 communicates with the outside. A piston rod 32 is movably connected inside the outer cylinder 31. The top end of the piston rod 32 extends outside the outer cylinder 31 and is fixedly connected to the first disk body 13. The rod body part of the piston rod 32 is a hollow rod, and a third through hole 33 is formed at the bottom of the hollow rod. A tension spring 34 is fixedly connected to the top of the inner cavity of the outer cylinder 31. The bottom of the tension spring 34 is fixedly connected to the piston part of the piston rod 32. The cavity where the tension spring 34 is located is a cavity 35, and the cavity 35 communicates with the hollow rod through the third through hole 33. The adjusting component 5 includes an annular ring 51 movably connected to the top end of the piston rod 32. A fourth through hole 52 is formed on the annular ring 51. The cavity of the piston rod 32 can communicate with the outside through the fourth through hole 52. A gasbag 6 is arranged at the top of the outer tube 11 for contacting the outer wall of the pipeline on the ozone disinfection machine. A top rod 121 is fixedly connected to the bottom of the inner tube 12. The bottom of the top rod 121 is conical and extends below the outer tube 11. With the above scheme, the operator penetrates the outer tube 11 through the plastic bag until the outer wall of the plastic bag contacts the bottom of the second disk body 14. Then, the annular ring 51 is rotated so that the top of the piston rod 32 is conducted through the fourth through hole 52. At this time, under the action of the pulling force of the tension spring 34, the piston rod 32 will move upward to discharge the gas in the cavity 35 through the third through hole 33 and the cavity of the piston rod 32. The upward movement of the piston rod 32 will also drive the inner tube 12 and the connecting ring 21 to move upward through the first disk body 13. At this time, the top of the inner tube 12 seals the first through groove 111, and the upward movement of the bottom of the rubber sleeve 22 will cause the upper part of the rubber sleeve 22 to deform. At this time, the top of the rubber sleeve 22 will squeeze the edge of the hole drilled by the outer tube 11 on the plastic bag. At this time, the second disk body 14 and the rubber sleeve 22 respectively squeeze the plastic bag from the outside and the inside, so as to ensure the sealing performance between the outer wall of the outer tube 11 and the plastic bag after the outer wall of the outer tube 11 passes through the plastic bag. Then, the pipeline on the ozone disinfection machine passes through the outer tube 11 and contacts the gasbag 6 and then enters the inner tube 12 to complete the connection, thus solving the problem that ozone leakage may occur when the two connecting pipes on the ozone disinfection machine are connected to the inside of the plastic bag through the holes punctured in the plastic bag. It should be noted that when the inner tube 12 moves upward, the ejector rod 121 will also move upward and retract into the outer tube 11, thus avoiding the situation that after the ejector rod 121 pierces a hole in the plastic bag, the ejector rod 121 will damage the medical textiles inside the plastic bag; When the device is reset, the operator can squeeze the piston rod 32 back into the outer cylinder 31 by pressing.
[0020] Such as Figures 1 - 4 and Figure 9 As shown, a guide ring 122 is fixedly connected to the outside of the outer tube 11 and is located inside the rubber sleeve 22. The outer wall of the part of the outer tube 11 located inside the rubber sleeve 22 is frustum-shaped and expands from bottom to top. The wall thickness of the upper and middle parts of the rubber sleeve 22 is less than that of the middle and lower parts; With the above scheme, by setting the guide ring 122, the expansion of the outer wall of the outer tube 11, and the design of the wall thickness of the rubber sleeve 22, it is beneficial to ensure that when the bottom end of the rubber sleeve 22 moves upward, the top end of the rubber sleeve 22 can stably squeeze the plastic bag between the rubber sleeve 22 and the second disk 14, thus ensuring the sealing between the outer tube 11 and the inner edge of the hole in the plastic bag.
[0021] Such as Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the adjusting assembly 5 further includes arc-shaped positioning blocks 53 fixedly connected to the annular ring 51 in a circumferential array. When the concave surface on the arc-shaped positioning block 53 contacts the top of the piston rod 32, the cavity of the piston rod 32 can be completely communicated with the through hole four 52; The top of the piston rod 32 is fixedly connected with a hose 4. The top end of the piston rod 32 can be communicated with the hose 4 through the through hole four 52. A through hole two 114 is opened at the top of the outer tube 11, and the hose 4 is communicated with the airbag 6 through the through hole two 114; With the above scheme, when the piston rod 32 moves upward, the gas inside the cavity 35 will enter the cavity of the adjusting assembly 5 through the piston rod 32, the airbag 6 and the through hole two 114. At this time, the airbag 6 will expand and squeeze the pipeline on the ozone disinfection machine inserted therein, further ensuring the sealing between the pipeline on the ozone disinfection machine and the device.
[0022] Such as Figure 1 , Figure 2 , Figure 4 and Figures 7 - 9 As shown, a positioning assembly 7 for detecting whether the bottom of the second disk 14 is in contact with the plastic film is arranged in a circumferential array at the bottom of the second disk 14; The positioning component 7 includes a rotating rod 71 hinged to the bottom of the second disc body 14. An elastic block 72 is also elastically connected inside the second disc body 14. A clamping block 73 is provided on the inner tube 12. One end of the elastic block 72 abuts against the hinged part of the rotating rod 71 under the action of its own elastic force. The outside of the hinged part of the rotating rod 71 is cam-shaped; A limiting rod 321 is fixedly connected to the bottom of the piston rod 32. The bottom of the limiting rod 321 is conical, and the bottom of the limiting rod 321 initially extends below the outer cylinder 31 and penetrates the second disc body 14. A clamping groove 322 that is initially engaged with the clamping block 73 is provided on the limiting rod 321; When the rotating rod 71 rotates into the second disc body 14, the top of the rotating rod 71 can squeeze the elastic block 72 and make the clamping block 73 disengage from the clamping groove 322; With the above solution, before the second disc body 14 contacts the plastic bag, by pulling the bag body at the edge of the hole opened on the plastic bag and making it in a taut state, the rotating rod 71 is squeezed by the plastic bag and rotates and retracts into the second disc body 14. At this time, when the second disc body 14 rotates around the axis, the top of the rotating rod 71 will push the elastic block 72 to move, so that the clamping block 73 releases the clamping connection with the clamping groove 322, so as to ensure that when the inner edge of the hole is located above the rubber sleeve 22, the operator can control the adjusting component 5 to make the telescopic rod component 3 work, so as to ensure that the subsequent device can effectively seal the connection between the outer tube 11 and the hole of the plastic bag.
[0023] The working principle and usage process of the present invention: First, the operator penetrates the outer tube 11 through the plastic bag until the outer wall of the plastic bag contacts the bottom of the second disc body 14. Then, the annular ring 51 is rotated so that the top of the piston rod 32 is conducted through the through hole four 52. At this time, under the action of the pulling force of the tension spring 34, the piston rod 32 will move upward to discharge the gas in the cavity 35 through the through hole three 33 and the cavity of the piston rod 32. The upward movement of the piston rod 32 will also drive the inner tube 12 and the connecting ring 21 to move upward through the first disc body 13. At this time, the top of the inner tube 12 seals the through groove one 111, and the upward movement of the bottom of the rubber sleeve 22 will cause the upper part of the rubber sleeve 22 to deform. At this time, the top of the rubber sleeve 22 will squeeze the edge of the hole drilled by the outer tube 11 on the plastic bag. At this time, the second disc body 14 and the rubber sleeve 22 respectively squeeze the plastic bag from the outside and the inside, so as to ensure the sealing performance between the outer wall of the outer tube 11 and the plastic bag after the outer wall of the outer tube 11 passes through the plastic bag. Then, the pipeline on the ozone disinfection machine passes through the outer tube 11 and contacts the airbag 6 and then enters the inner tube 12 to complete the connection; The upward movement of the inner tube 12 will also drive the ejector rod 121 to move upward and retract into the outer tube 11, thus avoiding the situation that after the ejector rod 121 penetrates a hole in the plastic bag, the ejector rod 121 will damage the medical textiles in the plastic bag; Before the second disk body 14 contacts the plastic bag, by pulling the bag body at the edge of the hole opened on the plastic bag and making it in a taut state, the rotating rod 71 is squeezed by the plastic bag and rotates and retracts into the second disk body 14. At this time, when the second disk body 14 rotates around the axis, the top of the rotating rod 71 will push the elastic block 72 to move, so that the clamping block 73 releases the clamping connection to the clamping groove 322, so as to ensure that when the inner edge of the hole is located above the rubber sleeve 22, the operator can control the adjusting assembly 5 to make the telescopic rod assembly 3 work, so as to ensure that the subsequent device effectively seals the connection between the outer tube 11 and the hole of the plastic bag; When the piston rod 32 moves upward, the gas inside the cavity 35 will enter the cavity of the adjusting assembly 5 through the piston rod 32, the airbag 6 and the second through hole 114. At this time, the airbag 6 will expand and squeeze the pipeline on the ozone disinfection machine inserted therein, further ensuring the sealing performance between the pipeline on the ozone disinfection machine and the device.
