Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a surface debridement tool for treating stage IV pressure ulcers. Background Technology

[0002] Pressure ulcers (also called bedsores or pressure sores) are pathological conditions caused by prolonged pressure, resulting in damage to the skin and underlying tissues. They typically occur in areas subjected to prolonged pressure (such as the buttocks, sacrum, coccyx, and heels). During treatment, doctors stage the wound based on its depth, extent, and severity, usually dividing it into four stages (or four phases). Stage IV, also known as the deep injury stage (the most severe), is characterized by wounds involving deep tissues such as muscles, bones, and even joint capsules and tendons. It usually involves a large amount of necrotic tissue, resulting in deep, large wounds that are difficult to heal.

[0003] Currently, debridement scalpels are used clinically to clean pressure ulcers. Before debridement, the wound needs to be rinsed, with saline solution being the most effective. Saline solution is usually drawn with a syringe and used in conjunction with cotton balls to clean the periphery of the pressure ulcer. However, the syringe has a limited capacity, requiring multiple aspirations of saline solution, which is inconvenient. Furthermore, because saline solution comes into contact with the patient's skin, it can splatter everywhere, making waste fluid difficult to collect and treat. Therefore, this solution provides a surface debridement tool for treating stage IV pressure ulcers to address the aforementioned problems. Utility Model Content

[0004] To address the aforementioned technical problems, a surface debridement tool for treating stage IV pressure ulcers is provided. This technical solution resolves the issues raised in the background section.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A surface debridement tool for treating stage IV pressure ulcers includes a base plate, a support plate fixedly connected to the upper end of the base plate, several sets of guide grooves extending through the outer side of the upper end of the support plate, a cleaning component and a collection component arranged on the lower side of the support plate, slide rails fixedly connected to both ends of the support plate, sliders slidably connected inside the slide rails, a movable frame fixedly connected to the other end of the sliders, an electric push rod fixedly installed at the top of the movable frame, a telescopic baffle and a light lamp arranged inside the movable frame, an airbag fixedly connected to the inner wall of the arc groove at the lower end of the telescopic baffle, a storage box fixedly installed at the right end of the movable frame, and an airbag and a magnetic suction frame fixedly installed at the left end of the movable frame.

An adsorption element is provided on the lower surface of the cleaning nozzle, and the adsorption element is adsorbed and connected to the magnetic holder through the adsorption element.

[0010] Preferably, the collection assembly includes a guide plate, which is fixedly connected to the lower end of the support plate. Several sets of inclined blocks are fixedly connected to the bottom inner wall of the guide plate. A collection pipe is fixedly connected to the lower end of the guide plate. The lower end of the collection pipe is connected to the waste liquid tank. A pair of filter screens are symmetrically installed on the inner wall of the waste liquid tank.

[0011] Compared with the prior art, this utility model proposes a surface debridement tool for treating stage IV pressure ulcers, which has the following beneficial effects: 1. This utility model includes a movable frame that moves along a slide rail, allowing its position to be adjusted and moved to the patient's wound location. This is driven by an electric push rod, which in turn extends a telescopic baffle downwards. The air bladder is then inflated by squeezing, and in conjunction with the electric push rod and telescopic baffle, the patient's limb can be immobilized to some extent, preventing trembling due to pain. Medical staff can then use a cleaning nozzle, while wearing gloves, to clean the wound. A water pump draws saline solution from the medicine tank, which is then sprayed out through the cleaning nozzle to clean the wound. This not only improves the cleaning effect but also ensures hygiene. The waste fluid after cleaning is prevented from splashing onto the patient and medical staff by the telescopic baffle and movable frame, making waste fluid collection more convenient and enhancing its practicality.

[0012] 2. In this utility model, the patient is placed on the support plate. The waste liquid generated during the cleaning process flows into the guide plate through the guide channel. The waste liquid on the guide plate is guided by the inclined block to flow to the lowest point and is finally collected into the waste liquid tank through the collection pipe. This facilitates the collection of the waste liquid after cleaning and avoids splashing and pollution. At the same time, the waste liquid tank is equipped with a filter screen to filter the waste liquid and perform solid-liquid separation treatment. Attached Figure Description

Detailed Implementation

[0015] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0016] Reference Figure 1-5As shown, a surface debridement tool for treating stage IV pressure ulcers includes a base plate 1. A support plate 2 is fixedly connected to the upper end of the base plate 1. Several sets of guide grooves 201 are opened through the outer side of the upper end of the support plate 2. A cleaning component 12 and a collection component 13 are arranged on the lower side of the support plate 2. When the patient is placed on the support plate 2, the waste liquid generated during the cleaning process flows into the collection component 13 through the guide grooves 201, thereby facilitating the collection of the waste liquid after cleaning and avoiding splashing and contamination. Slide rails 3 are fixedly connected to both the left and right ends of the support plate 2. A slider 4 is slidably connected inside the slide rail 3. A movable frame 5 is fixedly connected to the other end of the slider 4. An electric push rod 6 is fixedly installed at the top of the movable frame 5. A telescopic baffle 7 and a light 14 are arranged inside the movable frame 5. The lower end of the telescopic baffle 7 is arc-shaped and an air bag 8 is fixedly connected to the inner wall of the arc groove. A storage box 9 is fixedly installed at the right end of the movable frame 5. An air bag 10 and a magnetic suction frame 11 are fixedly installed at the left end of the movable frame 5. In use, the device moves along the slide rail 3 to adjust its position, allowing it to be positioned at the patient's wound location. This is achieved by the electric push rod 6, which in turn extends the telescopic baffle 7 downwards. Subsequently, the airbag 8 is inflated by squeezing the airbag 10. Combined with the electric push rod 6 and the telescopic baffle 7, this device can immobilize the patient's limb to some extent, preventing them from shaking due to pain. During wound cleaning, the waste fluid generated by the cleaning component 12 is prevented from splashing onto the patient and medical staff by the telescopic baffle 7 and the moving frame 5, making waste fluid collection more convenient and enhancing its practicality.

[0017] Specifically, in this embodiment, a set of casters 101 is fixedly installed at the lower end of the base plate 1. The casters 101 facilitate the movement of the device and improve its flexibility.

[0018] Specifically, in this embodiment, the output end of the electric push rod 6 passes through the top plate of the movable frame 5 and is fixedly connected to a connector 601, and the other end of the connector 601 is fixedly connected to the rear end of the telescopic baffle 7.

[0019] Specifically, in this embodiment, one end of the airbag 10 is fixedly connected to a connecting tube 1001, and the other end of the connecting tube 1001 is connected to the input end of the airbag 8. By squeezing the airbag 10, the airbag 8 is inflated. In conjunction with the electric push rod 6 and the telescopic baffle 7, the patient's limb can be fixed to a certain extent. Fixation by the airbag 8 can effectively provide support and reduce the discomfort and skin damage caused by traditional fixation methods.

[0020] Specifically, in this embodiment, the cleaning assembly 12 includes a medicine tank 1201 and a water pump 1202. Both the medicine tank 1201 and the water pump 1202 are located on the upper end of the base plate 1. The input end of the water pump 1202 is connected to the medicine tank 1201 through a water pipe, and the output end of the water pump 1202 is connected to the cleaning nozzle 1203 through a water pipe. An adsorption element 1204 is provided on the lower surface of the cleaning nozzle 1203, and the adsorption element 1204 is adsorbed and connected to the magnetic holder 11 through the adsorption element 1204. Medical staff can use the cleaning nozzle 1203 to clean the patient's wound through gloves. The water pump 1202 draws out the saline solution inside the medicine box 1201 and sprays it out through the cleaning nozzle 1203 to clean the patient's wound. This not only improves the cleaning effect but also ensures cleanliness and hygiene. After cleaning, the cleaning nozzle 1203 is placed on the magnetic holder 11 by the adsorption effect of the suction component 1204 and the magnetic holder 11.

[0021] Specifically, in this embodiment, the collection component 13 includes a guide plate 1301, which is fixedly connected to the lower end of the support plate 2. Several sets of inclined blocks 1302 are fixedly connected to the bottom inner wall of the guide plate 1301. A collection pipe 1303 is fixedly connected to the lower end of the guide plate 1301, and the lower end of the collection pipe 1303 is connected to a waste liquid tank 1304. A pair of filter screens 1305 are symmetrically installed on the inner wall of the waste liquid tank 1304. Waste liquid generated during the cleaning process flows into the guide plate 1301 through the guide channel 201. The waste liquid on the guide plate 1301 is guided by the inclined blocks 1302 to flow towards the lowest point and is finally collected into the waste liquid tank 1304 through the collection pipe 1303. This facilitates the collection of the cleaned waste liquid and prevents splashing and pollution. Simultaneously, the waste liquid tank 1304 is equipped with filter screens 1305 to filter the waste liquid, achieving solid-liquid separation.

[0022] The working principle of this utility model is as follows: The patient is placed on the support plate 2, and the movable frame 5 moves on the slide rail 3, thereby adjusting the position of the movable frame 5. The movable frame 5 is moved to the patient's wound position by the electric push rod 6. This drives the telescopic baffle 7 to extend downwards. Then, by squeezing the air bag 10, the air bag 8 is inflated. With the electric push rod 6 and the telescopic baffle 7, the patient's limb can be fixed to a certain extent to prevent the patient from shaking due to pain. Then, medical staff can pick up the cleaning nozzle 1203 through gloves to clean the patient's wound. The water pump 1202 draws out the saline solution inside the medicine tank 1201 and sprays it out through the cleaning nozzle 1203 to clean the patient's wound. This not only has a better cleaning effect but is also more hygienic. After cleaning, the cleaning nozzle 1203 is placed on the magnetic frame 11 by the adsorption effect of the suction member 1204.

[0023] During the debridement process, the waste liquid generated by the cleaning component 12 is prevented from splashing onto patients and medical staff by the telescopic baffle 7 and the movable frame 5, making waste liquid collection more convenient and practical. The waste liquid generated during the cleaning process flows into the guide plate 1301 through the guide channel 201. The waste liquid on the guide plate 1301 is guided by the inclined block 1302 to flow towards the lowest point and is finally collected into the waste liquid tank 1304 through the collection pipe 1303, which facilitates the collection of waste liquid after cleaning and avoids waste liquid splashing and pollution. At the same time, the waste liquid tank 1304 is equipped with a filter screen 1305 to filter the waste liquid and perform solid-liquid separation treatment.
