Description

Technical Field

[0001] The present invention relates to the technical field of wound care and disinfection, in particular to a wound care and disinfection device specially used for limbs. Background Art

[0002] A wound is a rupture formed by a break in the continuity of the skin and its underlying tissues. People inevitably injure their limbs in the course of daily life, which can lead to skin damage and wounds. To prevent wound infection, skin preparation and disinfection should be performed according to the location and extent of the wound, thoroughly removing foreign matter and dirt. In the field of surgery, disinfection of patients' limb wounds is essential. When performing disinfection operations on children who are afraid of pain and are very active, doctors also need to use wound care and disinfection devices for auxiliary treatment.

[0003] According to the search, a Chinese patent with publication number CN204684323U discloses a wound cleaning irrigator. This utility model uses a micro-electric water pump to inject saline solution from a liquid storage tank into a cleaning cotton brush to reduce the discomfort of direct irrigation. The cleaning cotton brush is then rolled and wiped on the wound surface to improve the cleaning effect.

DETAILED DESCRIPTION

[0042] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0043] See also Figure 1-Figure 3 The present invention provides a technical solution: a wound care and disinfection device specially used for limbs, comprising a liquid collecting hopper 1 for collecting waste liquid and a straight cylinder 4 for pressurizing and supplying cleaning liquid above the liquid collecting hopper 1, protective shells 101 are docked on both sides of the liquid collecting hopper 1, and a horizontally placed placement seat 102 is fixed below the protective shell 101, and a waste discharge port is provided at the bottom of the liquid collecting hopper 1, and the lower edge of the waste discharge port is higher than the bottom wall of the placement seat 102; the placement seat 102 is placed horizontally on the medical care bed, and the waste liquid generated by the care and disinfection is collected through the liquid collecting hopper 1, and a disc-shaped container for collecting waste liquid is placed at the bottom of the liquid collecting hopper 1, so that the disc-shaped container can leak-proof and collect the waste liquid collected in the liquid collecting hopper 1, thereby preventing the waste liquid generated by disinfection from contaminating the care bed.

[0044] See also Figure 1-Figure 3 The outside of the protective shell 101 on both sides of the liquid collecting bucket 1 is respectively installed with a front end sleeve 3 and a rear end sleeve 301 for restricting the patient's limbs. The interior of the front end sleeve 3 and the rear end sleeve 301 are both installed with air bags 302 that are inflated and pressed against the patient's limbs by air pumped into them.

[0045] In this embodiment, the hand or foot of the child patient to be disinfected is inserted into the front sleeve 3 and extended from the rear sleeve 301. By adjusting the position of the child patient's limb, the entire surface of the wound is directed toward the upper position of the liquid collecting bucket 1, which facilitates the doctor to observe the wound position. After the wound position is determined, an air pump is used to supply air to the air bags 302 inside the front sleeve 3 and the rear sleeve 301, so that the two air bags 302 can be expanded to press against the patient's limb position, so that the child patient's limb to be treated can be stably restrained, preventing the wound position from changing when the child patient moves his limb.

[0046] On the contrary, by reversely extracting the air in the airbag 302 through the air pump, the airbag 302 can be contracted away from the limb position of the child patient, and the limb that has been disinfected can be withdrawn from the wound care disinfection device.

[0047] See also Figure 1-Figure 5 The protective shell 101 is internally movably sleeved with a gear ring 2, and a clamp seat 201 is installed on the inner wall of the gear ring 2. The gear ring 2 limits the straight cylinder 4 for pressurized cleaning fluid supply through the clamp seat 201.

[0048] In this embodiment, the internal gear ring 2 can be blocked and protected by the protective shell 101 to prevent the movable gear ring 2 from being entangled by debris outside the protective shell 101. At the same time, the two ends of the straight cylinder 4 are installed on the clamp seat 201 on the inner wall of the gear ring 2, so that the straight cylinder 4 can be suspended horizontally above the liquid collecting bucket 1, ensuring that the cleaning liquid discharged from the straight cylinder 4 can be collected by the liquid collecting bucket 1.

[0049] See also Figure 1-Figure 3 A drive shaft 103 is connected between the two protective shells 101, and one end of the drive shaft 103 is connected to a steering motor 104 installed on the outer wall of the protective shell 101. Gears that drive the ring gear 2 to rotate are installed on both sides of the drive shaft 103.

[0050] In this embodiment, the steering motor 104 is started to rotate forward and reverse, so that the steering motor 104 can drive one of the drive shafts 103 and the gears on both sides of the drive shaft 103 to realize forward and reverse rotation. When the gear is engaged with the ring gear 2, the ring gear 2 can complete the rotation in the opposite direction of the gear, so that the ring gear 2 will drive the straight cylinder 4 to complete the circumferential rotation adjustment, so that the straight cylinder 4 can rotate to different angles in the circumferential direction, thereby facilitating the extraction of cleaning fluid from different angles according to the patient's wound position, and facilitating adaptive flushing and disinfection according to the wound position.

[0051] See also Figure 1 and Figure 2A liquid storage tank 5 is provided on one side of the placement seat 102, and a one-way valve is installed at one end of the top of the straight cylinder 4, and a hose is connected between the one-way valve and the liquid storage tank 5, and a liquid suction pump 501 is installed on the liquid storage tank 5 to transport cleaning liquid into the hose. The one-way valve can prevent the cleaning liquid in the liquid storage tank 5 from flowing back into the hose. By starting the liquid suction pump 501, the cleaning liquid in the liquid storage tank 5 is transported into the one-way valve through the hose. The transported cleaning liquid will push open the one-way valve and enter the straight cylinder 4, so that the straight cylinder 4 can complete the injection and storage of the cleaning liquid.

[0052] See also Figure 4-Figure 7 A liquid inlet end cap 401 is sealed and installed at one end of the straight cylinder 4 close to the rear end sleeve 301. A piston 402 is provided in the inner cavity of the straight cylinder 4 to squeeze and pressurize the cleaning liquid. The end of the liquid inlet end cap 401 is connected to a connecting pipe that passes through the surface of the rear end sleeve 301. An injection pump 403 is also provided on one side of the placement seat 102 to inject fluid into the interior of the straight cylinder 4 through the connecting pipe to drive the piston 402 to move; the liquid inlet end cap 401 on the straight cylinder 4 is arranged opposite to the one-way valve for one-way introduction of cleaning liquid, and the cleaning liquid entering from the one-way valve and the fluid entering from the liquid inlet end cap 401 are separated by the piston 402.

[0053] In this embodiment, the fluid is fed into the straight cylinder 4 along the connecting pipe and the liquid inlet end cap 401 by starting the syringe pump 403, causing the piston 402 to move forward from the end of the straight cylinder 4 close to the liquid inlet end cap 401 toward the position of the one-way valve, so that the piston 402, pushed by the fluid, can increase the pressure of the cleaning liquid.

[0054] When the piston 402 moves to the one-way valve position for introducing cleaning fluid, the injection pump 403 withdraws the fluid that pushed the piston 402, and the liquid extraction pump 501 is started to re-inject cleaning fluid into the straight cylinder 4. The re-injected cleaning fluid will push the piston 402 in the reverse direction to move it to a position close to the liquid inlet end cover 401. At this time, the re-injected cleaning fluid can complete the reset of the piston 402.

[0055] It should be emphasized that when the injection pump 403 introduces fluid into the straight cylinder 4 to enable the piston 402 to pressurize the cleaning liquid, the liquid extraction pump 501 on the top of the liquid storage tank 5 will not inject cleaning liquid into the straight cylinder 4.

[0056] See also Figure 4-Figure 9A liquid outlet channel 404 communicating with the inner cavity is provided inside the straight cylinder 4. The communication port between the liquid outlet channel 404 and the inner cavity is located below the one-way valve. A motor 405 is installed at the end of the straight cylinder 4 away from the liquid inlet end cover 401. Grooves are symmetrically provided on both sides of the bottom of the straight cylinder 4. A screw rod 407 is movably connected in one of the grooves. The output end of the motor 405 drives the screw rod 407 to rotate through a transmission device 406. When the piston 402 moves forward, the piston 402 will squeeze and push the cleaning liquid from the inner cavity of the straight cylinder 4 along the communication port into the interior of the liquid outlet channel 404, so that the interior of the liquid outlet channel 404 is filled with the cleaning liquid.

[0057] See also Figure 6 and Figure 9 The transmission device 406 consists of two pulleys and a transmission belt sleeved on the outside of the pulleys. The two pulleys are respectively connected to the output end of the motor 405 and one end of the screw rod 407. Starting the motor 405 can drive the two pulleys and the transmission belt to rotate together, so that the screw rod 407 rotates in the groove.

[0058] See also Figure 7 and Figure 8 The side of the straight cylinder 4 close to the liquid outlet channel 404 is threadedly connected with an equidistantly distributed valve head 6, the interior of the valve head 6 is abutted with a plug 601, and the interior of the plug 601 is plugged with a limit pin 602 that is connected to the inner wall of the straight cylinder 4. The outer side of the limit pin 602 is sleeved with an extrusion spring 603 for elastically pressing against the plug 601. Connecting the limit pin 602 to the inner wall of the straight cylinder 4 can prevent the plug 601 from telescoping and offsetting in the valve head 6.

[0059] In this embodiment, when the cleaning liquid is fed into the liquid outlet channel 404, the plug 601 is elastically pressed against the extrusion spring 603, causing the plug 601 to seal the valve head 6, thereby preventing the cleaning liquid from being discharged outward from the valve head 6 position of the liquid outlet channel 404.

[0060] See also Figure 4-11 A drainage seat 7 is fitted under the straight cylinder 4 and is used to slide and adjust the position to open the valve head 6 to spray the cleaning liquid. The drainage seat 7 is slidably engaged in the groove and is threadedly connected to the screw rod 407; a top cap 701 is provided in the center of the upper side of the drainage seat 7, and a confluence cavity 702 is provided around the drainage seat 7 near the top cap 701. The bottom of the drainage seat 7 is detachably connected to a liquid distribution nozzle 704 that is connected to the confluence cavity 702, and a partition plate is provided inside the liquid distribution nozzle 704 for evenly spraying the cleaning liquid.

[0061] In this embodiment, the drainage seat 7 is driven to slide under the straight cylinder 4 by the forward or reverse rotation of the screw rod 407. When the top cap 701 at the center of the upper side of the drainage seat 7 is squeezed with the plug 601 at the bottom of the straight cylinder 4, the top cap 701 causes the plug 601 to squeeze into the valve head 6 and compress the extrusion spring 603, which can disengage the plug 601 from the valve head 6 and create a gap for draining the cleaning liquid. At this time, the pressurized cleaning liquid in the liquid outlet channel 404 flows into the confluence cavity 702 along the gap between the plug 601 and the valve head 6, and the cleaning liquid is introduced from the confluence cavity 702 into the liquid distribution nozzle 704. At the same time, the cleaning liquid is evenly sprayed to the wound position of the designated limb through the liquid distribution nozzle 704 and the partition plate.

[0062] When the screw rod 407 drives the drainage seat 7 to move to the bottom of the evenly distributed valve head 6, the drainage seat 7 will squeeze the evenly distributed plug 601, so that the evenly distributed valve head 6 can be opened intermittently and introduce cleaning liquid to the liquid distribution nozzle 704. The cleaning liquid can be sprayed intermittently on long wounds. The intermittent introduction of cleaning liquid can prevent excessive cleaning liquid from being sprayed on the wound area, thereby preventing the cleaning liquid from being wasted during spraying.

[0063] The liquid distribution nozzle 704 is connected to the bottom of the drainage seat 7 by a threaded connection or an interference fit, and the liquid distribution nozzle 704 and the drainage seat 7 are detachably installed. After the liquid distribution nozzle 704 completes the flushing and disinfection of the wound, the liquid distribution nozzle 704 can be removed and replaced to prevent the liquid distribution nozzle 704 from causing cross infection when disinfecting the wound on the patient's limb.

[0064] See also Figures 8-10 The two ends of the upper side of the drainage seat 7 are embedded with blocking pieces 703 corresponding to the valve head 6. The blocking pieces 703 are made of rubber. When the drainage seat 7 slides under the straight cylinder 4, the blocking pieces 703 at the two ends of the upper side of the drainage seat 7 will elastically deform when they contact the plug 601. At this time, the contact between the blocking piece 703 and the plug 601 will not open the valve head 6.

[0065] See also Figure 1 、 Figure 2 、 Figure 4-Figure 6 、 Figure 10 and Figure 11 , coating mechanisms 9 for evenly spreading the cleaning liquid on the wound are provided on both sides of the drainage seat 7, the coating mechanism 9 includes a magnetic rod 901 magnetically connected to the drainage seat 7, the lower end of the magnetic rod 901 is connected to a lower support 902 through a damping shaft, a side support 903 is fixed to one side of the lower support 902, and a cotton swab 904 for applying the cleaning liquid is clamped in the middle of the lower support 902 and the side support 903.

[0066] In this embodiment, the cotton swabs 904 distributed crosswise in the lower support 902 and the side support 903 are clamped, and then one end of the magnetic rod 901 is magnetically docked on both sides of the drainage seat 7. The lower support 902 and the side support 903 can be driven to rotate by rotating the damping shaft. When the liquid dispensing nozzle 704 sprays the cleaning liquid toward the wound, the two groups of cross cotton swabs 904 can fit the wound position of the patient's limb to gather the flushing cleaning liquid, thereby slowing down the speed of the cleaning liquid dripping into the liquid collecting bucket 1.

[0067] When the drainage seat 7 moves horizontally along the straight tube 4, the drainage seat 7 will drive the two groups of crossed cotton swabs 904 to apply the gathered cleaning liquid, thereby further improving the uniformity of wound disinfection and cleaning, so that the cleaning liquid is gathered at the wound position to achieve efficient and even coating. When the wound disinfection is completed, the coating mechanism 9 is disassembled and removed from both sides of the drainage seat 7 to facilitate the replacement of the cotton swabs 904.

[0068] See also Figures 1-6 、 Figure 10-13 , a segmented protective assembly 8 is provided on the straight cylinder 4 to prevent the cleaning liquid from flowing horizontally on the long wound, and a pushing seat 705 for opening and closing the segmented protective assembly 8 is symmetrically installed on both sides of the drainage seat 7;

[0069] The segmented protection assembly 8 for preventing the lateral flow of cleaning fluid on the long wound comprises:

[0070] The slide 801 is slidably connected to the outside of the straight cylinder 4, and the top of the slide 801 is threadedly connected to a knob 802. By rotating the knob 802 and threadedly connected to the slide 801, the segmented protection component 8 can be restricted and installed on the straight cylinder 4; the outer baffles 803 at both ends of the slide 801 are rotated by the hinge axis, and the outer baffle 803 and the slide 801 are sleeved with a torsion spring 804 for preventing the outer baffle 803 from rotating and unfolding, and the inner rotation of the outer baffle 803 is connected to the inner baffle 806; the outer baffle 803 is movably connected to a roller 805 at one end close to the slide 801, and an extension is provided at the end of the inner baffle 806 away from the slide 801; a baffle rod 10 is symmetrically fixed between two adjacent gear rings 2.

[0071] In this embodiment, the segmented protection component 8 is placed in the middle area of ​​the long wound position, and then the drainage seat 7 is driven by the screw 407 to move toward the segmented protection component 8 to achieve flushing and disinfection of the first side position of the segmented protection component 8. When the squeezing seats 705 on both sides of the drainage seat 7 squeeze the rollers 805 of the outer baffle 803, the outer baffle 803 will rotate around the hinge shafts at both ends of the slide 801 and compress the torsion spring 804. At this time, the outer baffles 803 on both sides of the slide 801 will rotate relative to each other. When the two outer baffles 803 rotate and expand away from each other, the outer baffle 803 drives the extension portion of one end of the inner baffle 806 to squeeze against the baffle rod 10, so that the inner baffle 806 can be stored in the outer baffle 803, so that the rotated and expanded outer baffle 803 can provide an unobstructed passage for the movement of the drainage seat 7 and the liquid distribution nozzle 704, so that the drainage seat 7 can drive the liquid distribution nozzle 704 and the coating mechanism 9 to move to the other side of the segmented protection assembly 8;

[0072] When the screw rod 407 drives the drainage seat 7 and the coating mechanism 9 to move from the position passing through the segmented protection component 8 to the direction away from the segmented protection component 8, the drainage seat 7 drives the liquid dispensing nozzle 704 to perform flushing and disinfection at the second side of the segmented protection component 8;

[0073] When the pushing seats 705 on both sides of the drainage seat 7 are out of contact with the roller 805, the torsion spring 804 squeezes and resets the outer baffle 803, so that the two outer baffles 803 can be reset and rotated to complete the close closure. At this time, the two closed and docked outer baffles 803 and inner baffles 806 can provide segmented protection for the long wound position, ensuring that when the drainage seat 7 drives the liquid spray nozzle 704 to flush and disinfect the long wound position on the limb, it can prevent excessive cleaning liquid from overflowing to the opposite side of the segmented protection component 8, so that the long wound can be divided into two sections to complete the disinfection in sequence, and when disinfecting one section of the long wound, excessive cleaning liquid will not affect the other section of the long wound, ensuring that the long wound can dry quickly during segmented flushing, thereby alleviating the pain of the limb wound of children patients.

[0074] Please note that Figure 1 、 Figure 2 、 Figure 6 、 Figure 9 、 Figure 10 、 Figure 12 and Figure 13 An anti-slip groove is provided on the outside of the straight cylinder 4, and a protrusion matching the anti-slip groove is provided on the inside of the slide 801. When the rotating knob 802 is screwed on the slide 801, the knob 802 is pressed against the top wall of the straight cylinder 4, causing the protrusion on the inside of the slide 801 to be clamped with the anti-slip groove, thereby completing the position adjustment and position locking of the segmented protection component 8 on the straight cylinder 4.
