Description

Technical Field

The invention relates to the technical field of cold compress sterilization, in particular to a sterilization device for producing cold compresses with multi-angle coverage.

Background Art

Medical cold compress patch is a new type of medicine made from polymer gel as raw material. The main function of medical cold compress patch is to cool down the local skin of the human body. In the process of preparing medical cold compress patch, a sterilization device is needed to disinfect and sterilize the medical cold compress patch to ensure that the cold compress patch is put into use in a sterile state.

There are many existing technologies for sterilization devices, such as:

Chinese patent publication number CN218010416U discloses a sterilization device for the production of medical cold compresses, including a shell and a motor fixedly installed on the top of the shell, a sterilization component and three storage boxes for storing cold compresses are arranged on the inner side of the bottom of the shell; the placement cavity is divided into a plurality of independent placement slots by arranging a grid, and a single cold compress can be inserted into the placement slot accordingly, and the cold compress can be sorted, and when the cold compress is placed in the placement cavity below, the upper half of the cold compress can be fanned out in the trapezoidal cavity, thereby increasing the irradiation area with the ultraviolet sterilization lamp tube, improving the permeability and improving the sterilization efficiency; the first gear is driven to rotate by the motor, and the second gear is meshed with the second gear, and the meshing relationship between the second gear and the annular tooth surface on the ring, so that the second gear can revolve around the first gear, and the second gear can also rotate on its own, thereby continuously changing the direction of the storage box and switching the irradiation surface with the ultraviolet sterilization lamp tube.

It can be seen that when sterilizing the processed cold compress, multiple cold compresses are usually placed in the placement slots, and the adjacent cold compresses are separated by partitions, and then the cold compresses are rotated around the ultraviolet lamp by a rotating mechanism to achieve the purpose of sterilization. However, the adjacent cold compresses are close to each other, and the amount of ultraviolet radiation received by the inner cold compress is reduced compared to the outermost cold compress (forming some dead angles or shadow areas), thereby affecting the sterilization effect of the inner cold compress. Secondly, when one side of the cold compress is completely exposed, the cold compress loses its restriction at this time, causing the cold compress to fall off, affecting the efficiency of sterilization.

Example

As shown in Figures 1, 2, 3 and 7, a sterilization device for the production of a multi-angle covering patch is provided, including a sterilization tank 100 and a driving device 101. A door panel is hinged on one side of the sterilization tank 100. The driving device 101 is used to drive an air supply device 102 and a plurality of frames 110 arranged at the bottom to rotate. An ultraviolet sterilization lamp 103 is arranged at the center of the bottom end of the sterilization tank 100. Similar to the prior art, the driving device 101 is composed of a motor and a planetary gear. The planetary gear and the air supply device 102 rotate synchronously. In this way, the cold compress can be sterilized at different angles by rotation.

Secondly, the frame 110 is symmetrically rotatably connected to the limit baffles 120 on both sides. The limit baffles 120 are used to alternately limit the cold compress, and power units 200 are provided on both sides of the frame 110. The power unit 200 is connected to the air supply device 102. The power unit 200 is used to drive the limit baffle 120 on one side to flip under the action of gas. An expansion unit 300 is provided inside the limit baffle 120. A plurality of exhaust holes 121 connected to the power unit 200 are provided on the side of the expansion unit 300. The expansion unit 300 pushes the two ends of the cold compress outward, and the negative pressure formed around the exhaust holes 121 adsorbs the ends of the cold compress to prevent the cold compress from detaching from the frame 110 after the limit baffles 120 on both sides are opened, thereby affecting the sterilization effect of the cold compress.

It can be seen that when sterilizing the cold compress, a cold compress is placed in each frame 110, and then the cold compress is sterilized by rotating it, and the limiting baffles 120 on both sides are opened and closed alternately to expose the edges of the cold compress on both sides. At this time, the amount of ultraviolet radiation received by the cold compress increases, thereby improving the sterilization effect of the cold compress.

Therefore, on the basis of the above structure, the structure of the power unit 200 is further disclosed in combination with Figures 4 and 5. The power unit 200 includes a winding reel 210 and a lower air pipe 211. During the rotation of the cold compress patch, the traction rope wrapped around the winding reel 210 is used to pull the limit baffle 120 to rotate, so that the limit baffles 120 on both sides are alternately opened and closed. In this way, when the cold compress patch is close to the ultraviolet sterilization lamp 103, the entire surface of the cold compress patch can be completely irradiated by ultraviolet rays, thereby improving the sterilization effect of the cold compress patch.

Furthermore, the upper and lower winding disks 210 are coaxially connected to the lower air pipe 211, the top of the lower air pipe 211 is rotatably connected to the upper air pipe 201, the lower air pipe 211 is connected to the upper air pipe 201, and a pressure relief valve is arranged in the lower air pipe 211. On the other hand, the piston top rod 212 is threadedly connected to the inner part of the lower air pipe 211, the inner part of the piston top rod 212 is connected to the upper air pipe 201, and the bottom of the upper air pipe 201 is fixedly connected to the piston head, the gas box 203 that the piston head is sleeved with is fixedly connected to the frame 110, and the third spring 202 on the piston top rod 212 is respectively against the gas box 203 and the piston head. In this way, when ventilating the gas box 203, the air pressure can be used to push the piston head to move, so that the piston top rod 212 moves up and drives the winding disk 210 to rotate. Among them, the limiting baffle 120 on one side is opened and the limiting baffle 120 on the other side is closed, so as to fully expose the side of the cold compress patch close to the ultraviolet sterilization lamp 103, reduce the influence of dead angles and shadow areas, and thus achieve a comprehensive and uniform sterilization effect.

It should be noted that when the limiting baffle 120 on one side is opened, one side of the cold compress is exposed. As the frame 110 rotates, when the back side of the cold compress is completely exposed, the cold compress is completely exposed to ultraviolet rays.

In order to enable the cold compress to cover multiple angles, the cold compress also rotates itself while turning, and to ensure the smooth rotation of the cold compress, the air boxes 203 on both sides are interconnected, and an air pipe is rotatably connected between the air boxes 203 on both sides, and the other end of the air pipe is connected to the air supply device 102, so that when the air supply device 102 and the driving device 101 are rotated together, the rotation of the frame 110 can be carried out smoothly without affecting the air supply to the air box 203.

Because the limit baffle 120 on one side is in the process of opening, the limit baffle 120 on the other side is in a gradually closing state, therefore, in order to ensure that the limit baffle 120 is closed smoothly, a first spring 111 is sleeved on the traction rope, and the two ends of the first spring 111 are respectively fixedly connected to the block, and the block on both sides are respectively fixedly connected to the limit baffle 120 and the frame 110. In this way, when the limit baffle 120 changes from opening to closing, the elastic potential energy of the first spring 111 can be used to push the limit baffle 120 and the frame 110 to close, so as to prevent the cold compress from falling off.

Furthermore, by providing a friction surface at the joint between the frame 110 and the cold compress patch, when the limit baffle 120 on one side is unfolded, the friction surface can be used to increase the friction between the cold compress patch and the cold compress patch to prevent sliding between the bottom of the cold compress patch and the frame 110.

It should be noted that: with the supply of gas, the air pressure in the piston push rod 212 gradually increases. When the gas flows out from the pressure relief valve, the flow of gas can be used to form a negative pressure in the exhaust hole 121, thereby restricting the cold compress.

As shown in FIG8 and in combination with FIG7, when the gas is supplied to the exhaust holes 121 on both sides, the limit baffle 120 on one side is opened and the limit baffle 120 on the other side is closed (i.e., the exhaust holes 121 on one side need to be supplied with gas, and the exhaust holes 121 on the other side do not need to be supplied with gas), which requires selective supply of gas to the exhaust holes 121. To this end, the box body 144 is fixedly connected to the end of the upper air pipe 201, and the upper air pipe 201 and the box body 144 are connected. The box body 144 is fixed to the side of the frame 110, and the box body 144 is symmetrically provided with a circular hole on one side relative to the upper air pipe 201. When the limit baffle 120 and the frame 110 are closed, the circular hole is connected to the exhaust hole 121, so that the gas passes through the inside of the box body 144 and flows to the exhaust hole 121 through the circular hole, so that a negative pressure is formed at the exhaust hole 121.

In addition, the movable plate 143 slidably connected in the box body 144 is used to guide the gas introduced into the upper air pipe 201. The two ends of the movable plate 143 are fixedly connected to the fixed rod 142. The fixed rod 142 is slidably connected to the box body 144, and one end of the fixed rod 142 away from the movable plate 143 is fixedly connected to the horizontal plate. The second spring 140 is sleeved on the fixed rod 142. On the other hand, the horizontal plate is slidably connected to the frame 110, and the other end of the horizontal plate is fixedly connected to the telescopic top rod 141. The telescopic top rod 141 is used to push the horizontal plate to move when the frame 110 is closed, so that the fixed rod 142 moves in the box body 144, so as to select the circular hole for exhaust.

Next, when the limit baffle 120 and the frame 110 are closed, the movable plate 143 moves to the edge of the circular hole on one side, and the movable plate 143 is away from the upper air pipe 201, so that the gas entering the box body 144 can be guided to enter from the circular hole on the other side.

What needs to be considered is that: when the limit baffle 120 is closed with the frame 110, the circular hole and the exhaust hole 121 are connected, and the instantaneous release of gas will impact the limit baffle 120. Under the elastic action of the first spring 111, the impact force of the gas and the elastic potential energy of the second spring 140 are not sufficient to overcome the elastic force of the first spring 111 (that is, the limit baffle 120 will not rotate outward), and at this time the limit baffle 120 still remains closed with the frame 110.

In order to form a negative pressure on the side of the exhaust hole 121 close to the cold compress patch so as to restrict the cold compress patch, a one-way valve is provided on the side of the exhaust hole 121 close to the cold compress patch so that after the gas passes through the exhaust hole 121, a negative pressure is formed on the side close to the cold compress patch. Secondly, the exhaust holes 121 on both sides are connected with auxiliary air pipes 130, and the other end of the auxiliary air pipe 130 is connected to the limit baffle 120 with an air inlet 122. In this way, combined with FIG. 6, when the gas enters the exhaust hole 121 through the exhaust hole 121 and the auxiliary air pipe 130, the expansion part 300 is expanded by the push of the gas, and the expansion part 300 pushes the cold compress patch outward, so that the cold compress patch is away from the closed limit baffle 120. In addition, after the expansion part 300 expands outward, the gas is discharged from the end of the air inlet 122, thereby improving the circulation of the gas inside the tank, thereby bringing the microorganisms around the cold compress patch to the ultraviolet irradiation area, increasing their chances of being killed, and shortening the sterilization time.

Returning to FIG. 7 , the specific structure of the expansion part 300 is disclosed below. The expansion part 300 includes an airbag 310 and an auxiliary baffle 311 fixed to the side of the airbag 310. The auxiliary baffle 311 blocks the end of the air inlet hole 122 under normal conditions. The airbag 310 is bonded to a limiting baffle 120 on one side of the auxiliary baffle 311, and a plurality of raised balls are arranged at the joint between the airbag 310 and the cold compress patch, so that when the airbag 310 is squeezed and expanded, the cold compress patch is pushed outward by the raised balls, thereby reducing the contact area with the cold compress patch, increasing the space for gas circulation, and improving the sterilization efficiency.

That is, the gas pushes the auxiliary baffle 311 to squeeze the airbag 310, and the airbag 310 expands outward. At this time, one side of the airbag 310 is squeezed by the auxiliary baffle 311 to form an inclined surface, and the upper side of the airbag 310 away from the protruding ball protrudes outward (as shown in conjunction with FIG. 9 ). Therefore, after the gas pushes the auxiliary baffle 311 out, the airbag 310 guides the ejected airflow, and the gas flows along the limiting baffle 120. In this way, negative pressure can be formed on both sides of the airbag 310, thereby ensuring that the cold compress and the protruding ball are in close contact, and preventing the cold compress from detaching from the frame 110.

The above shows and describes the basic principles, main features and advantages of the present invention.
