Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a bed unit ozone disinfection machine. Background Technology

[0002] Ozone disinfection of bedding units utilizes the strong oxidizing properties of ozone. Ozone gas is generated by a bedding unit ozone disinfection machine to penetrate and disinfect the bed and bedding units (such as mattresses, quilts, sheets, pillow cores, etc.). It can quickly and efficiently kill bacteria, viruses, fungi and other microorganisms, achieving the effects of disinfection, deodorization and whitening, thereby ensuring the health and safety of patients and medical staff and preventing cross-infection.

[0003] Chinese patent CN219517258U discloses a bed unit ozone sterilizer. This ozone sterilizer uses a tube take-up roller to wind and store the required hose. The length of the hose can be flexibly adjusted by the clamping force of the fasteners and the tension of the torsion springs on both sides of the tube take-up roller. The hose is always connected to the ozone generator group inside the machine, which increases the convenience of the staff to use the equipment. The concave connecting groove and sliding cover provide further protection for the outer interface of the hose, which improves the overall practicality of the device.

[0004] The aforementioned patent requires manually rotating the nut to secure the hose when extending it; similarly, retracting the hose requires rotating the nut in the opposite direction, a process that is somewhat cumbersome. If the initial hose extension is insufficient, the user must repeat the above steps to continue extending and securing the hose, undoubtedly increasing the complexity and inconvenience of the operation. Furthermore, when the hose is wound around the central tube, it is prone to deformation due to pressure, resulting in poor ozone flow within it and affecting its effectiveness. Utility Model Content

[0005] The purpose of this invention is to provide a bed unit ozone disinfection machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows.

[0007] An ozone sterilizer for a bed unit includes a body and two air tubes. Inside the body, two central tubes are rotatably mounted via a spiral spring. The ends of the two air tubes are rotatably connected to the two central tubes respectively. A flexible tube is connected to and wound around the outer surface of the central tube. A ratchet is installed on the outer surface of the central tube. A torsion bar is rotatably connected through the side wall of the body. A pawl matching the ratchet is installed at the end of the torsion bar. A torsion spring is sleeved on the outer surface of the torsion bar. The two ends of the torsion spring are connected to the inner wall of the body and the torsion bar respectively. A sliding cover is damped and slidably mounted on the outer surface of the body.

[0008] As can be seen, by setting up the ratchet and pawl, when the hose is pulled outward, the central tube can rotate normally and release the hose. When the hose is stopped from being pulled, the self-locking property of the pawl and ratchet can be used to fix the hose. If the length pulled out is not enough, the hose can be pulled outward again. The length of the hose can be flexibly adjusted, thereby reducing the complexity of operation and making it easy to use.

[0009] Furthermore, a solenoid valve is installed on the outer surface of the trachea, a medical two-way valve is installed on the outer surface of the tubing, and an air nozzle is installed at the end of the tubing.

[0010] Furthermore, a baffle is installed on the inner wall of the body near the sliding cover. Two through slots are symmetrically opened on the surface of the baffle, and the hose passes through the inside of the through slots. A medical two-way valve is set on the side of the baffle facing the sliding cover, and the diameter of the medical two-way valve is greater than the height of the through slot.

[0011] Furthermore, a torsion block is installed at the end of the torsion bar.

[0012] Furthermore, the edges on both sides of the through groove are rounded.

[0013] Furthermore, a handrail is installed on the rear side of the machine body, and the outer surface of the handrail is covered with a rubber sleeve. Universal wheels are installed at the four corners of the bottom of the machine body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0015] 1. This utility model, through the setting of ratchet and pawl, allows the central tube to rotate normally and release the hose when the hose is pulled outward. When the hose is stopped from being pulled, the self-locking property of the pawl and ratchet can be used to fix the hose. If the pulled-out length is insufficient, the hose can be pulled outward again. The length of the hose can be flexibly adjusted, thereby reducing the complexity of operation and making it easy to use.

[0016] 2. This utility model seals the inside of the trachea by activating the solenoid valve, and then the medical staff manually closes the medical two-way valve. At this time, the inside of the tubing is in a sealed state. When it is wrapped around the central tube, the air inside the tubing cannot be discharged, making it difficult to be compressed and deformed, thus ensuring the flow of ozone inside during subsequent use.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0024] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0025] like Figure 1-4As shown, a bed unit ozone sterilizer includes a body 100 and two air pipes 104. Inside the body 100, two central tubes 102 are rotatably mounted via spiral springs. The ends of the two air pipes 104 are rotatably connected to the two central tubes 102 respectively. A flexible hose 105 is connected to and wound around the outer surface of the central tubes 102. A ratchet 107 is mounted on the outer surface of the central tubes 102. A torsion bar 108 is rotatably connected through the side wall of the body 100. A pawl 103 matching the ratchet 107 is mounted at the end of the torsion bar 108. A torsion spring 101 is sleeved on the outer surface of the torsion bar 108. The two ends of the torsion spring 101 are connected to the inner wall of the body 100 and the torsion bar 108 respectively. A sliding cover 106 is damped and slidably mounted on the outer surface of the body 100.

[0026] In use, medical personnel open the sliding cover 106 and pull the hose 105 outwards. At this time, the central tube 102 can rotate normally and release the hose 105, while the spiral spring begins to wind up. When pulling the hose 105 stops, the anti-reverse rotation capability of the pawl 103 and ratchet 107 achieves the purpose of self-locking the central tube 102, thus automatically fixing it when pulling the hose 105 stops. If the pulled-out length is insufficient, it can be pulled outwards again, thereby reducing the complexity of operation and making it easy to use. When it is necessary to wind up the hose 105, simply rotate the torsion bar 108 to disengage the pawl 103 from the ratchet 107. At this time, the contracted spiral spring begins to release its elasticity, causing the central tube 102 to rotate in the opposite direction and rewind the hose 105 onto the central tube 102.

[0027] It is worth noting that the internal components of the unit 100 include an ozone generator assembly, an air pump, and a power supply. The specific working principle and structural layout are consistent with the prior art. This part is not within the scope of protection of this application, so it will not be elaborated on here.

[0028] Preferably, a solenoid valve 200 is installed on the outer surface of the trachea 104, a medical two-way valve 201 is installed on the outer surface of the hose 105, and an air nozzle 202 is installed at the end of the hose 105.

[0029] When it is necessary to wrap the pulled-out hose 105 around the central tube 102, the solenoid valve 200 can be activated first to seal the inside of the air tube 104. Then, medical staff can manually close the medical two-way valve 201. At this time, the inside of the hose 105 is sealed. When it is wrapped around the central tube 102, the air inside the hose 105 cannot be discharged, making it difficult to be compressed and deformed. This ensures the flow of ozone inside the hose during subsequent use.

[0030] Preferably, a baffle 300 is installed on the inner wall of the body 100 near the sliding cover 106. Two through grooves 301 are symmetrically opened on the surface of the baffle 300, and the hose 105 passes through the inside of the through groove 301. A medical two-way valve 201 is set on the side of the baffle 300 facing the sliding cover 106, and the diameter of the medical two-way valve 201 is greater than the height of the through groove 301.

[0031] The medical two-way valve 201 can block the outside of the baffle 300 to prevent the air nozzle 202 from being retracted into the body 100. The length of the through groove 301 is consistent with the distance between the two partitions on the central tube 102, so it can prevent the hose 105 from scraping against the inner wall of the through groove 301 due to the continuous change of its position during the winding or wrapping process.

[0032] Preferably, a torsion block 400 is installed at the end of the torsion bar 108.

[0033] The torsion block 400 makes it easy to manually rotate the torsion bar 108.

[0034] Preferably, the edges on both the front and rear sides of the through groove 301 are rounded.

[0035] The rounded corners give the edge of the through groove 301 a smooth and flat arc surface, which further reduces the possibility of the hose 105 scraping against the inner wall of the through groove 301.

[0036] Preferably, a handrail 500 is installed on the rear side of the body 100, the outer surface of the handrail 500 is provided with a rubber sleeve, and universal wheels 501 are installed at the four corners of the bottom of the body 100.

[0037] The armrests 500 and casters 501 facilitate the movement of the machine body 100, and the rubber sleeves increase the friction when gripping the machine, improving comfort and reducing the risk of slipping.

[0038] The above is a detailed description of the present invention in conjunction with specific embodiments, and it should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, any equivalent substitutions or obvious modifications made without departing from the concept of the present invention, and which have the same performance or use, should be considered as falling within the patent protection scope defined by the submitted claims.
