Description

Technical Field

[0001] This utility model relates to the field of spinal cord electrical stimulation technology, specifically to a fixation structure for fixing an external experimental stimulator in spinal cord electrical stimulation therapy. Background Technology

[0002] During spinal cord stimulation therapy, the external experimental stimulator used for treatment needs to be fixed to the patient's body surface to ensure the smooth progress of the treatment. Currently, the stimulator is generally fixed by adhesive tape in clinical practice. However, this fixation method has many obvious defects: the adhesion of the tape is difficult to control precisely. If it is too loose, the stimulator may shift or even fall off when the patient moves, affecting the continuity and stability of the treatment; if it is too tight, it will cause additional pressure on the patient's skin and cause discomfort. Meanwhile, direct contact between the adhesive tape and the skin can hinder normal skin respiration, especially with prolonged use. This can create a damp and hot environment at the contact site, increasing the risk of skin allergies, redness, and even breakage. Furthermore, the wires connected to the stimulator lack specialized organization and restraint, making them prone to compression and tangling when secured with tape. This can not only cause wire abrasion, affecting signal transmission or power supply, but also inconvenience the patient's daily activities. In fact, the pulling of the wires may further shift the position of the stimulator, interfering with the treatment effect. Moreover, when the stimulator needs to be inspected, adjusted, or replaced, the process of tearing off the tape can pull on the patient's skin, causing pain. Repeated application and removal can exacerbate skin damage, bringing additional pain and burden to the patient. Utility Model Content

[0028] The mounting body 1 is detachably connected to the positioning belt 6.

[0029] The lower end of the mounting body 1 is provided with a plurality of connecting buttons 10, and the positioning belt 6 is provided with a plurality of button holes 11. Each button hole 11 is evenly distributed below the mounting body 1. The mounting body 1 is detached and connected to the positioning belt 6 through the cooperation of the connecting buttons 10 and the button holes 11.

[0030] The top cover 3 is made of transparent material and has several ventilation holes 12. The top cover 3 is connected to the housing 1 by a zipper and is used to limit the stimulator placed in the housing cavity 2. The zipper is a nylon zipper and its length matches the length of the upper edge of the housing 1. It is set at the upper edge of the housing and the corresponding edge of the top cover.

[0031] The bottom of the mounting cavity 2 is provided with a second wiring hole 13, and a third wiring hole 15 is provided along the length of the positioning band 6, penetrating the positioning band 6. The second wiring hole 13 is connected to the third wiring hole 15 through a fourth wiring hole 16 provided on the positioning band 6.

[0032] The diameters of the first wiring hole 5, the second wiring hole 13, the third wiring hole 15, and the fourth wiring hole 16 are all 3-8mm. A silicone protective ring with a thickness of 1-2mm is provided on the inner edge of each of the three wiring holes. The first wiring holes 5 are symmetrically distributed on both sides of the mounting cavity 2. The second wiring hole 13 is located at the center of the bottom of the mounting cavity 2 and is perpendicularly connected to the fourth wiring hole 16. This is to prevent wire wear.

[0033] The positioning band 6 is an elastic cotton band with a width of 5-10 cm. The adhesive layer 8 is made of medical pressure-sensitive adhesive and is applied to the entire contact surface at the lower end of the positioning band 6.

[0034] The outer wall of the device 1 is surrounded by a pressure-reducing gasket. This gasket is made of a composite of sponge and fiber cotton and its shape is adapted to fit the outer wall of the device 1. It is used to reduce pressure on the patient's skin. The pressure-reducing gasket surrounding the outer wall of the device effectively disperses pressure. When used with optional gaskets, it can prevent pressure sores caused by prolonged pressure, making it especially suitable for comatose or other long-term bedridden patients.

[0035] The transparent material of the top cover 3 is medical-grade polyvinyl chloride with a thickness of 0.5-1mm. The vent holes 12 are evenly distributed on the surface of the top cover 3, with a diameter of 2-3mm, and each vent hole 12 is equipped with a dust filter. In use, it can also be used with a gasket, which is placed on the patient to prevent pressure sores.

[0036] Working principle

[0037] When using this invention, firstly, peel the release layer 9 from the adhesive layer 8 at the lower end of the positioning band 6. Then, use the adhesive layer 8 to attach and fix the positioning band 6 to a suitable position on the patient's body. Utilizing the elasticity of the positioning band 6, both stability and flexibility to accommodate patient movement are ensured. Next, place the stimulator required for spinal cord electrical stimulation into the receiving cavity 2 of the receiving body 1. Then, connect the top cover 3 to the receiving body 1 using a nylon zipper to limit the stimulator and prevent it from falling out of the receiving cavity 2. Since the top cover 3 is made of transparent medical-grade polyvinyl chloride, it is easy for medical personnel to observe the working status of the stimulator. Simultaneously, the vent 12 on the top cover allows air circulation inside and outside the receiving cavity 2, and the dust filter inside the vent provides dust protection. The stimulator's wires can be adjusted according to actual needs. Choose a suitable wiring method: the wires can pass through the first wiring hole 5 on the housing cavity 2, or through the second wiring hole 13 at the bottom of the housing cavity 2, and then through the fourth wiring hole 16 and the third wiring hole 15 on the positioning band 6. The silicone protective rings on the inner edges of each wiring hole can prevent the wires from being worn during use. The pressure-reducing gaskets surrounding the outer wall of the housing 1 are made of a composite of sponge and fiber cotton, which can reduce the pressure of the housing on the patient's skin. With the gaskets that may be used, pressure sores can be effectively prevented from occurring in the patient. In addition, the housing 1 and the positioning band 6 can be detached and connected by connecting buttons 10 and button holes 11. This not only makes it convenient to adjust the position of the housing 1 according to the actual situation to achieve a better fixation effect, but also allows the positioning band 6 to be replaced separately, further reducing the cost of use.
