Description

Technical Field

[0001] The utility model relates to the field of medical articles, in particular to an ultrasonic water jet debridement auxiliary device for diabetic foot. Background Art

[0002] Ultrasonic water jet uses high-frequency ultrasonic energy to act on soft tissue, destroying necrotic tissue and bacterial particles through mechanisms such as mechanical effects and cavitation effects, thereby achieving the purpose of clearing infected and necrotic tissue. This process helps reduce inflammatory responses and promote healing.

[0003] Ultrasonic water jets are currently widely used in the debridement of diabetic foot. Specifically, during debridement, the patient's legs are appropriately raised to elevate the patient's feet; a basin or other container is placed under the patient's feet; and the blade of the ultrasonic water jet device is pointed at the debridement site for debridement. During the ultrasonic water jet debridement process, water will flow down or splash, and necrotic human tissue will flow down or splash with the water, and water mist will be generated. The basin under the patient's feet can collect the flowing water and necrotic human tissue, but some splashed water and human tissue may fall out of the basin, and the water mist cannot be handled. The water, human tissue that cannot be collected, and the generated water mist have obvious adverse effects on the surrounding environment.

[0004] A search revealed patent application number 201911337537.6, which discloses a protective shield for debridement of lower leg or foot ulcers. This shield completely covers the patient's foot and ultrasonic water jet during debridement, preventing the escape of water, necrotic tissue, and water mist, thus protecting the surrounding environment. However, if the shield completely covers the patient's foot and ultrasonic water jet, the water mist that permeates the shield will seriously affect the operator's vision and may hinder the normal debridement process.

[0025] When the utility model is used, Figure 7As shown, the device is placed on the bed and close to the patient's feet; the patient's legs are placed on the leg support frame 3 to elevate the patient's feet, and the patient's feet are located above the collection box 2, with the shielding cover 41 covering the patient's feet; then the exhaust fan 44 is turned on, and ultrasonic water jet debridement is performed. Most of the water and necrotic tissue generated by debridement flow into the collection box 2 for collection. The shielding cover 41 blocks the splashing water and necrotic tissue that may appear during debridement to prevent them from flying too far. The exhaust effect of the exhaust fan 44 can suck the mist generated by debridement into the air duct 43, and the tiny droplets in the mist are absorbed by the demisting filter 45, and the air without small droplets is discharged. It can be seen that the utility model can prevent water, necrotic tissue and water mist from affecting the surrounding environment during ultrasonic water jet debridement.

[0026] After using the utility model, the water collected in the collection box 2 is poured out, and the surface of the shielding cover 41 and the ventilation plate 42 is cleaned and can be used next time. After using the utility model many times, the ventilation plate 42 can be removed, the interior of the shielding and demisting structure 4 can be cleaned and the demisting filter 45 can be replaced.

[0027] The demisting filter is an existing technology and is widely used in equipment that needs to remove water mist. The patent application number is 202120907715.0. The demisting filter 45 of the utility model adopts the mechanism of the existing technology, and its appearance and size are made to match the air duct 43. The exhaust fan 44 can also be an existing fan, and an axial flow fan can be selected, and its exhaust volume is 100m 3 The exhaust fan 44 is directly provided with a power supply interface.

[0028] The specific structure of the shielding cover 41 is preferably: the shielding cover 41 includes a shielding cover top plate 411 and two shielding cover side plates 412, the shielding cover top plate 411 is low in the front and high in the back, the two shielding cover side plates 412 are respectively connected to the left and right sides of the shielding cover top plate 411, the two shielding cover side plates 412 are symmetrically arranged, and the distance between the lower edges of the two shielding cover side plates 412 is greater than the distance between the upper edges.

[0029] The shielding cover top plate 411 is low in the front and high in the back, and the two shielding cover side plates 412 are respectively connected to the left and right sides of the shielding cover top plate 411. The two shielding cover side plates 412 are symmetrically arranged, and the distance between the lower edges of the two shielding cover side plates 412 is greater than the distance between the upper edges, so that the shielding cover 41 has a structure that is small in the front and large in the back, and small at the top and large at the bottom. The rear of the shielding cover 41 is open, and the debridement operation is performed from this direction.

[0030] Furthermore, preferably, pads 4111 are provided on both the left and right sides of the shielding cover top plate 411 , and the shielding cover side plates 412 are hinged to the shielding cover top plate 411 and rest on the pads 4111 .

[0031] The significance of such an arrangement is that both side panels 412 of the shielding cover can be rotated upwards and opened, so that the debridement operation can be performed from the left or right side of the diabetic foot ultrasonic water jet debridement auxiliary device.

[0032] In order to have better lighting during operation, it is preferred that the shielding cover top plate 411 and the shielding cover side plates 412 are both made of transparent plastic.

[0033] The shielding and demisting structure 4 should be fixed and can be connected to the base 1. Figure 5 and Figure 6 As shown, the ultrasonic water jet debridement auxiliary device for diabetic foot includes a connecting frame 5, which includes a vertical pole 51, a sleeve 53, left and right horizontal poles 52, front and rear horizontal poles 54, a lap plate 56, a support seat 55 and a support bolt 57; the vertical pole 51 is connected to the leg support frame 3 and is located next to the leg placement surface 311; the sleeve 53 is arranged in the left and right directions and connected to the top of the vertical pole 51; the left and right horizontal poles 52 pass through the sleeve 53 and cooperate with the sleeve 53; the front and rear ends of the front and rear horizontal poles 54 are respectively connected to the left and right horizontal poles 52 and the shielding and demisting structure 4; the support seat 55 is connected to the vertical pole 51, the support bolt 57 is vertically arranged and threadedly connected to the support seat 55, the lap plate 56 is radially arranged along the left and right horizontal poles 52 and faces forward, and the lap plate 56 is placed on the top of the support bolt 57.

[0034] The advantage of such an arrangement is that the demisting structure 4 can be lifted up to block the demisting structure, so that there is more space above the leg support frame 3, and the legs can be conveniently placed on the leg support frame 3. After the patient's legs are placed, the demisting structure 4 is lowered.

[0035] As previously mentioned, the present invention should be able to remove the ventilation plate 42 and the demisting filter 45. This is achieved by preferably connecting the ventilation plate 42 to the shield 41 with fasteners, and connecting the demisting filter 45 to the air duct 43 with fasteners; when the ventilation plate 42 is removed, the demisting filter 45 can be removed from the shield hole 4112.
