[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0031] See also Figures 1 to 9 , the present invention provides a technical solution: a clinical nursing wound cleaning device, a shell and a disinfection water tank 5 and a suction tube 6 arranged inside the shell, and a suction tube 8 for sucking purulent secretions from the wound is provided below the suction tube 6;

[0032] The suction tube 8 is provided with a pushing mechanism 3, which includes a plurality of arc blocks 308 arranged on the horizontal circumference of the suction tube 8. The plurality of arc blocks 308 move synchronously toward or away from each other in the horizontal direction with the suction tube 8 as the central axis.

[0033] A suction plug 7 is provided in the suction cylinder 6 and reciprocates in the vertical direction. When the suction plug 7 moves upward, the multiple groups of arc blocks 308 move synchronously in the horizontal direction toward the suction tube 8.

[0034] A conical suction head 9 is provided at the bottom of the suction tube 8, and the conical suction head 9 and the rolling ball 309 provided on the arc block 308 are in contact with the skin tissue around the wound of the patient.

[0035] See also Figure 1-Figure 3Before cleaning the purulent secretions at the patient's wound, choose whether to perform incision on the purulent secretions according to the skin condition of the patient's wound. When cleaning, align the trumpet mouth of the conical suction head 9 with the wound, and manually apply pressure to the shell to make the conical suction head 9 fit closely with the skin around the wound as much as possible. At this time, the rolling ball 309 set on the bottom of the arc block 308 is also in a state of pressing the skin. In the process of cleaning the purulent secretions, multiple groups of arc blocks 308 move synchronously toward the center, that is, toward the wound, thereby squeezing out the purulent secretions at the wound.

[0036] During the extrusion process, the suction plug 7 moves upward in the suction tube 6. The air pressure in the suction tube 6 changes, which generates an upward suction force in the conical suction head 9, thereby sucking the squeezed purulent secretions into the suction tube 6, thereby completing the collection of purulent secretions and realizing the process of "squeezing and sucking" the wound. The collection process of purulent secretions can also be completed after the wound is cleaned.

[0037] When the first cleaning is not thorough, repeat the above operation, but before the second cleaning, move the suction plug 7 downward to discharge the purulent secretions during the first cleaning into the collection bag, and then perform the second cleaning process. The cleaning operation of the patient's wound can be completed by multiple times of the above cleaning process.

[0038] In one of the more preferred embodiments, a propulsion rod 2 is provided in the shell and is driven by a multi-stage electric push rod 1 to reciprocate in the vertical direction. The fixed end of the multi-stage electric push rod 1 is fixedly connected to the shell. The propulsion rod 2 includes an integrally formed middle push rod 201, a right push rod 202, and a left push rod 203. The right push rod 202 is fixedly connected to a push column 301 sleeved on the suction tube 8. The push column 301 is rotatably connected to one end of a group of swing rods 302 through a rotating pin shaft, and the other end of the swing rod 302 is rotatably connected to a connecting block 303 through a rotating pin shaft. A group of arc blocks 308 are provided at the bottom of each group of connecting blocks 303.

[0039] like Figure 1-Figure 3 As shown, the multi-stage electric push rod 1 drives the push rod 2 to move in the vertical direction, and then drives the right push rod 202 and the push column 301 to move vertically. When the push column 301 moves in the vertical direction, the horizontal angle of the swing rod 302 is deflected, thereby driving the connecting block 303 to move in the horizontal direction, changing the spacing between the multiple groups of arc blocks 308. When the arc block 308 moves horizontally, since the skin has a certain elasticity, the arc block 308 or the rolling ball 309 squeezes the skin near the patient's wound, which will push the purulent secretions to move toward the incision position, and then squeeze the purulent secretions out of the patient's wound.

[0040] Furthermore, a limiting rod 310 is fixedly connected to the upper surface of the connecting block 303 , and the limiting rod 310 is slidably connected to the cross slide 304 through a penetrating slide groove, and the cross slide 304 is fixedly connected to the housing.

[0041] like Figure 3 and Figure 4 As shown, when the horizontal angle of the swing rod 302 is deflected, in order to prevent the connecting block 303 from following the push column 301 to move in the vertical direction, a limit rod 310 is provided on the connecting block 303, and the limit rod 310 can only slide along the through slide groove provided on the cross slide 304, thereby restricting the movement direction of the connecting block 303, driving the connecting block 303 to move only in the horizontal direction, thereby ensuring that the connecting block 303 can only change the horizontal position of the arc block 308 when moving.

[0042] On the basis of the embodiment of the pushing mechanism 3, a sleeve block 305 is fixedly connected to the bottom of the connecting block 303, one end of a No. 1 spring 307 is fixedly connected to the inner wall of the sleeve block 305, and the other end of the No. 1 spring 307 is fixedly connected to a sleeve rod 306, the sleeve rod 306 is in sliding contact with the inside of the sleeve block 305, and the lower surface of the sleeve rod 306 is fixedly connected to an arc block 308, and the rolling ball 309 rolls in a rolling ball groove opened at the bottom of the arc block 308.

[0043] like Figure 4 , Figure 6 and Fig. 9 As shown, during the squeezing process of the wound, the ball 309 needs to squeeze the skin around the wound and push the surrounding purulent secretions out of the incision. Therefore, by setting the sleeve block 305, the sleeve rod 306 and the No. 1 spring 307, when squeezing wounds at different positions on the body, since the human skin is slightly undulating and the patient has sores or moles, the No. 1 spring 307 can squeeze and push the skin around the wound while adapting to the skin surface conditions at different positions, thereby ensuring the squeezing process of the purulent secretions in the wound.

[0044] Among them, in order to ensure that the conical suction head 9 can be as close to the skin as possible, the outer wall of the suction tube 8 is fixedly connected with an annular hollow frame 10, and a movable ring 12 is provided in the annular hollow frame 10. The movable ring 12 is in sliding contact with the inner wall of the annular hollow frame 10 and the outer wall of the suction tube 8. The top of the movable ring 12 is fixedly connected to one end of the No. 3 spring 11, and the other end of the No. 3 spring 11 is fixedly connected to the inner wall of the annular hollow frame 10. The bottom of the movable ring 12 is fixedly connected to the conical suction head 9.

[0045] like Figure 4 , Figure 6 and Figure 7As shown, when cleaning the wound of the patient, the trumpet mouth of the conical suction head 9 needs to be as close to the skin around the wound as possible to ensure that the purulent secretions can be sucked into the suction tube 6. By setting the No. 3 spring 11, the No. 3 spring 11 is always in a compressed state during the cleaning process of the wound. The elastic potential energy of the No. 3 spring 11 is used to promote the conical suction head 9 to be in close contact with the skin surface, reduce the gap between the skin and the conical suction head 9, and ensure that the purulent secretions squeezed out of the wound can be sucked into the suction tube 6.

[0046] Furthermore, a suction plug 7 is fixedly connected to the middle push rod 201 , the suction plug 7 contacts the inner wall of the suction tube 6 , and the bottom of the suction tube 6 is fixedly penetrated by the suction pipe 8 .

[0047] like Figure 2 and Figure 8 As shown, the middle push rod 201 is driven to move in the vertical direction by the push rod 2, thereby driving the suction plug 7 to move vertically inside the suction tube 6. When the suction plug 7 moves upward, the purulent secretions are sucked into the suction tube 6 from the conical suction head 9 and the suction tube 8. When the suction plug 7 moves downward, the purulent secretions in the suction tube 6 can be discharged. At the same time, the disinfectant is sucked into the suction tube 6 through the reciprocating motion of the suction plug 7 in the vertical direction, thereby completing the reciprocating disinfection operation of the suction tube 6.

[0048] Furthermore, a disinfection component 4 is provided in the shell, and the disinfection component 4 includes a positioning plate 405 fixedly connected to the shell, a piston cylinder 402 is provided on the positioning plate 405, a circular through groove is opened on the top of the piston cylinder 402, one end of a No. 2 spring 404 is also fixedly connected to the top of the piston cylinder 402, and the other end of the No. 2 spring 404 is fixedly connected to a piston plate 403, and the outer peripheral side of the piston plate 403 is in contact with the inner wall of the piston cylinder 402, the piston cylinder 402 is fixedly penetrated by the disinfection water tank 5 through the liquid inlet pipe, and the piston cylinder 402 is also fixedly penetrated by a liquid outlet pipe 408, and a pressing block 401 is fixedly connected to the left push rod 203.

[0049] like Figure 1 , Figure 2 and Figure 5 As shown, the left push rod 203 and the pressing block 401 are driven to move in the vertical direction by the push rod 2. When the wound position is cleaned, the pressing block 401 is in a misaligned state with the piston cylinder 402 and the piston plate 403 in the vertical direction. Therefore, the pressing block 401 cannot drive the piston plate 403 to move downward, and the piston cylinder 402 will not interfere with the movement process of the pressing block 401. Therefore, the pressing block 401 is in an "air pressure" state when it is vertically misaligned with the piston plate 403.

[0050] Furthermore, the piston cylinder 402 is slidably connected to the positioning plate 405 through a slide groove, and a threaded rod 406 is rotated on the fixed axis on the positioning plate 405. The threaded rod 406 is threadedly connected to the bottom of the piston cylinder 402. The threaded rod 406 passes through the positioning plate 405 and the shell and is fixedly connected to the handle 407. A circular channel is opened on the top of the piston cylinder 402, which can be on the same vertical line as the pressing block 401 and can be passed by the pressing block 401.

[0051] like Figure 1 , Figure 2 and Figure 5 As shown, after the purulent secretions in the wound are cleaned, in order to disinfect the wound, the position of the piston cylinder 402 is changed so that the piston cylinder 402 and the piston plate 403 are directly below the pressing block 401, and the piston plate 403 is driven to move downward by the vertical downward movement of the pressing block 401, so that the disinfectant in the piston cylinder 402 is sprayed toward the wound from the liquid outlet pipe 408, and when the pressing block 401 moves upward, the No. 2 spring 404 gradually recovers its deformation and replenishes the disinfectant in the disinfection water tank 5 into the piston cylinder 402.

[0052] Therefore, a one-way valve is fixed on the liquid inlet pipe and the liquid outlet pipe 408. The one-way valve limits the flow direction of the disinfectant, so that the disinfectant can only flow from the disinfection water tank 5 to the piston cylinder 402, and the disinfectant can be continuously replenished into the piston cylinder 402.

[0053] It is worth noting that the shell mentioned in the present invention is a material with a specific certain strength such as plastic or metal. The function of the shell is to protect the multi-stage electric push rod 1, the disinfection water tank 5, the piston cylinder 402, the suction cylinder 6 and other components therein, and the shell is provided with a clearance groove corresponding to the movement stroke position of the right push rod 202 and the liquid outlet pipe 408 and other components, so it will not interfere with the movement of the internal components of the shell. At the same time, the shell is provided with a rotating door corresponding to the water inlet position of the disinfection water tank 5, so it will not affect the addition process of the disinfectant.

[0054] Working principle: This clinical nursing wound cleaning device, when cleaning the patient's wound, align the trumpet of the conical suction head 9 with the wound position, and manually apply pressure to the shell to make the conical suction head 9 as close to the skin around the wound as possible, and drive the push rod 2 and the middle push rod 201, right push rod 202 and left push rod 203 arranged thereon to move upward through the multi-stage electric push rod 1. When the right push rod 202 moves upward, the rolling ball 309 at the bottom of the arc block 308 presses the skin tightly and moves horizontally in the direction of the wound incision, thereby removing the wound. The purulent secretions are squeezed out, and when the middle push rod 201 moves upward, the air pressure in the suction tube 6 changes, causing an upward suction force to be generated in the conical suction head 9, and then the squeezed purulent secretions are sucked into the suction tube 6, thereby completing the collection of the purulent secretions and realizing the process of "squeezing and sucking" the wound, thereby further simplifying the wound cleaning work and improving the wound cleaning efficiency. After the cleaning is completed, the left push rod 203 moves in the vertical direction to complete the disinfection operation of the wound position, ensuring the hygiene of the wound position.

[0055] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
