Description

Technical Field

[0001] This utility model relates to a fixation bag for a spinal cord electrical stimulation therapy instrument, belonging to the field of medical device technology. Background Technology

[0002] Spinal cord stimulation therapy is a method of alleviating certain diseases by sending microcurrent pulses to specific areas of the spinal cord through implanted electrodes. The implanted spinal cord stimulator used in this treatment mainly consists of electrodes, an external stimulator, and a programmer. During use, the electrodes are implanted in the epidural space of the spinal cord and then connected to the external stimulator via extension leads. To prevent accidental traction on the extension leads, the positions of the external stimulator and the extension leads need to be fixed.

[0003] Currently, there are no specialized tools for securing stimulators in clinical practice. Medical staff typically use medical tape to attach the stimulator to the patient's body. During this process, the center of the tape should first cover the stimulator, and then both ends should be adhered to the patient's skin. Due to the size and weight of the stimulator, multiple layers of tape are needed for secure fixation. During treatment, when changing dressings and routinely checking the stimulator's operation, medical staff need to remove the tape to expose the stimulator for easier handling. Repeated tape changes not only increase the workload for medical staff but also easily damage the patient's skin, further increasing patient discomfort.

[0004] Furthermore, since stimulators are typically fixed to one side of the body, if the patient lies on their side facing that side, the stimulator will be pressed under their body. Given the size of the stimulator, this can be very uncomfortable. Using medical tape to fix the stimulator presents the drawback of difficulty in adjusting its position according to the patient's lying position. Utility Model Content

[0005] In order to solve the problems existing in the prior art, this utility model provides a fixing bag for a spinal cord electrical stimulation therapy instrument, which can securely fix the stimulator to the patient and is convenient to fix and remove.

[0006] This utility model achieves the above objectives by adopting the following technical solutions:

[0007] A fixing bag for a spinal cord electrical stimulation therapy device includes a bag body and a fixing patch. The back of the bag body is provided with a tongue, and the fixing patch is provided with a receiving socket. The tongue is detachably connected to the receiving socket.

[0008] The bag is square in shape and is composed of a base, side panels, and a top layer connected sequentially from back to front. The side panels surround the left and lower edges of the bag. The tab is located on the back of the base. The line connecting the start and end points of the side panels is set along the first diagonal of the bag. The upper and right sides of the bag are open to form an instrument insertion port. A fixing buckle is provided at the upper right corner of the base, and a buttonhole is provided at the upper right corner of the top layer.

[0009] Preferably, the length direction of the seam is perpendicular to the first diagonal.

Detailed Implementation

[0021] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] It should be noted that many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0023] The present invention provides a fixing bag for a spinal cord electrical stimulation therapy instrument, comprising a bag body 100 and a fixing sticker 200. The back of the bag body 100 is provided with a tongue 310, and the fixing sticker 200 is provided with a socket 320. The tongue 310 and the socket 320 are detachably connected.

[0024] The tongue 310 and the receiver 320 can be connected by a plug-in joint. Specifically, the receiver 320 is provided with a slot, which has a through-hole. The receiver has a rectangular cross-section, or a notch is provided on the side plate of the rectangular structure near the base to reduce the frictional contact area between the tongue and the receiver when inserted. The top of the tongue 310 is fixedly connected to the base, and the tongue extends downwards with a certain distance between it and the base, allowing the tongue 310 to be inserted into the slot of the receiver 320. When the patient lies on their side with the stimulator fixed on the side, the connection between the tongue and the receiver can be released, and the bag and stimulator can be removed. The receiver is made of plastic and is small in size, so it will not cause significant discomfort even when pressed under the body.

[0025] The bag body 100 is square and is composed of a base 110, side panels 120, and a top layer 130 connected sequentially from back to front. The side panels 120 surround the left and lower edges of the bag body 100, and the tab 310 is located on the back of the base 110. Specifically, the surface of the side panels 120 is parallel to the front-back direction, the rear edge of the side panels 120 is connected to the edge of the base 110, and the front edge of the side panels 120 is connected to the edge of the top layer 130.

[0026] The line connecting the start and end points of the side panel 120 is set along the first diagonal 140 of the bag body 100, making the upper and right sides of the bag body 100 open to form an instrument placement entrance 400. A fixing buckle 510 is provided at the upper right corner of the base 110, and a fastening seam 520 is provided at the upper right corner of the surface layer 130, through which the fixing buckle 510 passes. Considering that there is a certain distance between the base and the surface layer during use, the fixing buckle 510 can be set as a structure combining a small-diameter inner section and a large-diameter outer end. The small-diameter inner section matches the distance between the base and the surface layer, and the large-diameter outer end is similar to the structure of an ordinary button.

[0027] In use, determine the fixed position of the external stimulator 600, attach the fixing sticker 200 to that position, and then insert the tongue 310 on the back of the bag 100 into the socket 320 on the fixing sticker 200, thus securing the bag 100 to the patient. Next, insert the external stimulator into the bag 100 through the instrument insertion port 400, with the lead wire 610 on the right side of the external stimulator 600 exiting through the instrument insertion port. Finally, pass the fixing buckle 510 through the buckle seam 520 to prevent the external stimulator 600 from falling out of the instrument insertion port, thus placing the external stimulator 600 on the patient.

[0028] After treatment, disconnect the tongue 310 from the socket 320 and remove the bag 100. In practical application, each patient can be equipped with a dedicated fixation bag, and only the fixation patch 200 needs to be replaced for the next treatment. In addition, when the patient chooses to rest on their side, the bag 100 can be separated from the fixation patch 200 as needed, allowing them to lie on that side.

[0029] Preferably, the length direction of the fastening seam 520 is perpendicular to the first diagonal 140. After the external stimulator 600 is inserted into the bag body 100, it will expand the surface layer 130 outward, so that the force on the fastening seam 520 is mainly along the length direction of the fastening seam 520. The fastening seam 520 is stretched along the length direction, and the fixing buckle 510 is not easy to come out of the fastening seam 520. If the length direction of the fastening seam 520 is along the first diagonal 140, the force on the surface layer 130 will cause the aperture of the fastening seam 520 to increase along the width direction, and the fixing buckle 520 will easily come out of the fastening seam 510.

[0030] An observation window 131 is provided in the middle of the surface layer 130, so that the display content on the external stimulator can be seen through the observation window 131.

[0031] Connecting rings 111 are provided on both the left and right sides of the chassis 110. In practical applications, a belt can be threaded onto each connecting ring 111 on both sides, and the belt ends can be wrapped around the patient's waist and tied together to improve the fixation effect. The belt is the main component that bears the weight of the stimulator, while the fixing pad mainly serves to limit the lateral position of the stimulator. Together, the two achieve the fixation of the stimulator.

[0032] Preferably, the fixing patch uses Snap fasteners. Snap fasteners have strong adhesion, and with the aid of a waist belt, a relatively small area of ​​Snap fasteners can be used to secure the stimulator. Compared to traditional adhesive tape methods, this invention uses small-area Snap fasteners, which obstruct less skin, making it easier for medical staff to operate on the wound. It also reduces the difficulty of removal and alleviates patient discomfort.
