Description

Technical Field

[0001] The invention belongs to the technical field of wound negative pressure treatment, and in particular relates to a portable wound negative pressure treatment device for pediatric surgery. Background Art

[0002] Currently, in order to remove wound exudate and secretions and keep the wound clean, most methods are to clean the wound through negative pressure therapy to prevent bacterial accumulation and reduce the risk of infection.

[0003] Currently, when performing negative pressure wound therapy for burns on children's arms or legs, a moist sponge layer is usually covered on the wound and the treatment is performed in conjunction with the equipment. However, long-term negative pressure therapy can easily cause the gradual loss of moisture in the sponge layer and the wound surface. When the wound surface is dry, it is very easy to cause pain, which in turn increases the discomfort of the child. In addition, because the amount of wound secretions in children after burns is larger than that of adults, excessive wound secretions may lead to excessive loss of body fluids. Therefore, when performing negative pressure wound therapy for burns in children, it is necessary to properly remind the child to replenish fluids and electrolytes to prevent dehydration and electrolyte imbalance in children. At the same time, children are lively and active, and the existing negative pressure wound therapy device guide tube is long, and most of them are powered by wires, which cannot meet the needs. The children's need for free activities is not convenient for medical staff to carry, and the portability is low. Summary of the invention

Detailed Embodiments

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 As shown, the present invention provides the following technical solution: A portable wound negative pressure treatment device for pediatric surgery includes a main body housing 1. A water tank 4 and a fitting groove 8 are opened on the surface of the main body housing 1 near one side thereof. The fitting groove 8 is located between the water tanks 4. A waste liquid pipe 9 is fitted inside the fitting groove 8. A low-pressure pump 6 is fixedly installed inside the main body housing 1. The low-pressure pump 6 is located beside the fitting groove 8. The output end of the low-pressure pump 6 extends into the fitting groove 8 and is connected to the waste liquid pipe 9. A connecting pipe 23 is fixedly connected to the center of the bottom of the waste liquid pipe 9. A perforation 3 is opened at the bottom of the water tank 4. An expansion rubber 2 is fixedly installed inside the perforation 3. The expansion rubber 2 is located on both sides of the connecting pipe 23. A power storage compartment 26 is opened at the lower part of the side of the main body housing 1 away from the fitting groove 8. The power storage compartment 26 is located below the low-pressure pump 6. A battery 27 is installed inside the power storage compartment 26. Two sliding grooves 10 are symmetrically opened on both inner walls of the fitting groove 8 away from the low-pressure pump 6. Clamping strips 11 are symmetrically installed on the inner walls of the sliding grooves 10. One end of the waste liquid pipe 9 away from the low-pressure pump 6 is inserted inside a sleeve 13. The sleeve 13 is slidably arranged inside the fitting groove 8. Three-shaped sliding strips 14 are symmetrically installed on both sides of the sleeve 13. The sliding strips 14 are slidably arranged inside the sliding grooves 10. The sliding strips 14 are fitted and connected with the clamping strips 11.

[0024] Through the above technical solution, before use, cut two small openings in the protective film on the surface of the existing sponge cushion. The diameter of the small openings should be smaller than the width of the expansion rubber 2. Then cover the sponge cushion on the wound on the child's arm or leg. The sponge cushion is adhered to the skin through the protective film on its surface. Subsequently, fill the two water tanks 4 of the present device with clear water. After the expansion rubber 2 absorbs water and expands, wear the present device on the child's arm or leg, so that the connecting pipe 23 is fixedly connected to the interface on the sponge cushion, and the expansion rubber 2 contacts the sponge cushion covering the wound through the small openings and seals the small openings. Therefore, when the low-pressure pump 6 is started, the suction force generated by the low-pressure pump 6 will act on the sponge cushion through the waste liquid pipe 9 and the connecting pipe 23. Since the expansion rubber 2 contacts the sponge cushion, the water inside the expansion rubber 2 will gradually transfer to the sponge cushion due to the suction force generated by the operation of the low-pressure pump 6. The clear water in the water tank 4 will continue to moisten the expansion rubber 2. Furthermore, through the water transfer between the expansion rubber 2 and the sponge cushion, it is ensured that the sponge cushion and the covered wound will not dry out during long-term negative pressure treatment.

[0025] In addition, at the end of the treatment, by pushing one end of the sleeve 13, the slide bar 14 can be driven to slide inside the fitting groove 8 and squeeze the clamping bar 11 to deform it. Then, the clamping bar 11 moves to the outside of the fitting groove 8, driving the waste liquid pipe 9 to disengage from the plug-in connection with the low-pressure pump 6, completing the disassembly of the waste liquid pipe 9 and facilitating use.

[0026] Furthermore, a sponge clamping layer 12 is fixedly installed on the inner wall of the sleeve 13. The sponge clamping layer 12 is used to fill the gap between the waste liquid pipe 9 and the inner wall of the sleeve 13. An L-shaped clamping plate 16 is fixedly installed at the top of the sleeve 13. A clamping groove 25 is formed in the middle of the side of the sleeve 13 close to the low-pressure pump 6. The clamping groove 25 is arc-shaped, and an annular sealing ring 22 is arranged inside the clamping groove 25. The sealing ring 22 is sleeved on the connecting pipe 23, and the outer wall of the sealing ring 22 contacts the inner walls of the clamping groove 25 and the fitting groove 8.

[0027] Please refer to Figures 1-5 , by setting the sponge clamping layer 12, the static friction between the inner wall of the sleeve 13 and the waste liquid pipe 9 is increased, ensuring that when the sleeve 13 is pushed, the waste liquid pipe 9 will move synchronously with the sleeve 13, improving the portability of disassembly. The setting of the sealing ring 22 blocks the friction between the connecting pipe 23 and the inner walls of the clamping groove 25 and the fitting groove 8, ensuring the long-term use of the connecting pipe 23.

[0028] In addition, when medical staff carry it, they can directly hang the device on the pocket like a pen through the clamping plate 16, improving the portability of the device.

[0029] Furthermore, a time control module 15 is fixedly installed at the top of the main body shell 1. The time control module 15 is located above the low-pressure pump 6. Placement grooves 5 are symmetrically formed on the side of the main body shell 1 away from the fitting groove 8. The placement grooves 5 are located on both sides of the low-pressure pump 6, and a touch switch 24 and a reminder 7 are respectively fixedly installed inside the two placement grooves 5.

[0030] Please refer to Figures 1-3 , before use, medical staff can clamp and place different prepared medicaments inside the placement grooves 5. After they contact the touch switch 24, the low-pressure pump 6 is started through the time control module 15 and the treatment time of negative pressure treatment is controlled. When the extraction time reaches the preset time, the time control module 15 immediately controls the low-pressure pump 6 to stop running, and a sound is emitted through the reminder 7 to remind family members and children to replenish water. When family members and children replenish water by extracting the prepared medicaments, the medicaments are separated from the touch switch 24, and the touch switch 24 immediately sends a signal to the time control module 15, thereby restarting the low-pressure pump 6 to continue negative pressure treatment.

[0031] Further, a first silicone strip 18 is fixedly installed at the bottom of the main body housing 1. The first silicone strip 18 is of a U-shaped structure, and the opening of the first silicone strip 18 faces away from the low-pressure pump 6. A binding strap 20 is fixedly installed at the bottom of the main body housing 1 near the first silicone strip 18. The binding strap 20 is located below the low-pressure pump 6, and a second silicone strip 19 in the shape of a loop is fixedly installed on one side of the binding strap 20 close to the first silicone strip 18. Both of the two expansion rubbers 2 and the connecting pipe 23 are located within the opening of the first silicone strip 18. The width of the binding strap 20 is smaller than the width of the opening of the first silicone strip 18, and one end of the binding strap 20 away from the main body housing 1 can be inserted into the opening of the first silicone strip 18. A hook-and-loop fastener rough surface 21 is fixedly installed on one side of the binding strap 20 away from the second silicone strip 19. The hook-and-loop fastener rough surface 21 faces away from the main body housing 1. On one side of the bottom of the main body housing 1 away from the low-pressure pump 6, hook-and-loop fastener sticky surfaces 17 are symmetrically installed. The hook-and-loop fastener sticky surfaces 17 are located between the first silicone strips 18.

[0032] Please refer to Figure 1 and Figure 4 During use, cut two small openings in the protective film on the surface of the sponge cushion, and paste and cover the sponge cushion on the wound on the child's arm or leg. Then, after connecting the connecting pipe 23 to the interface on the sponge cushion, cover the device on the sponge cushion. Then, pull the binding strap 20 so that after it wraps around the child's arm or leg, it is fixed through the adhesion of the hook-and-loop fastener sticky surface 17 and the hook-and-loop fastener rough surface 21. At this time, the first silicone strip 18 cooperates with the second silicone strip 19 to closely adhere to the periphery of the protective film, ensuring that the device will not fall off during the child's activities, while pressing and sealing the four sides of the protective film, eliminating the use of a sealing strip, and cooperating with the expansion rubber 2 to prevent air leakage during use, improving convenience and simplifying the operation steps at the same time.

[0033] In addition, since this device is bound to the child's arm or leg through the hook-and-loop fastener sticky surface 17, the hook-and-loop fastener rough surface, and the binding strap 20, and is powered by the battery 27, during negative pressure wound treatment, the child can move freely. And because the connecting pipe 23 is relatively close to the sponge cushion, the actual length of the material guiding pipe used is sharply shortened, eliminating the problem that the sponge cushion falls off due to external factors catching the material guiding pipe when the child moves freely. At the same time, in cooperation with the subsequent first silicone strip 18 and second silicone strip 19, it saves the components that medical staff need to carry and improves the overall portability of the device.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
