Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical devices, in particular to a nephrostomy tube positioning pad. Background Art
[0002] A nephrostomy tube is required for percutaneous nephrolithotomy, open renal stone removal, severe upper urinary tract obstruction, and hydronephrosis. Nephrostomy tubes are placed in the lateral lumbar region (between the 11th intercostal space or the 12th intercostal margin, and between the scapular line and the posterior axillary line). Due to their posterior location, the tubes are susceptible to folding, twisting, displacement, bleeding, and poor drainage when the patient is recumbent. A folded towel placed at the waist is often used to prevent these adverse effects. However, this can cause redness, pressure injuries, and even pressure sores, exacerbating pain and discomfort. Furthermore, as substantial organs with abundant blood supply, renal bleeding can often occur due to infection, coagulation abnormalities, and other causes. If not detected promptly, hemorrhagic shock can easily occur, and in severe cases, death can result. Furthermore, a folded towel placed at the waist provides no secure support for the tube.

[0027] Please refer to Figures 1 to 3A nephrostomy tube positioning pad provided by an embodiment of the present invention includes a first support body 100 and a second support body 200. The first support body 100 and the second support body 200 can be spliced together, and a through groove 300 is formed in the middle of the first support body 100 and the second support body 200 after splicing; a fistula tube channel 250 is provided on the second support body 200, and one side of the fistula tube channel 250 is connected to the through groove 300 so that the fistula tube can pass through the through groove 300 and the fistula tube channel 250.
[0028] It should be noted that the first support body 100 and the second support body 200 both include an outer layer and a sponge lining, the sponge lining is arranged in the outer layer, and the shape of the sponge lining is designed and the outer layer covers the sponge lining so that the first support body 100 and the second support body 200 form a Figures 1 to 3 The shape shown in the figure is adopted, and the comfort is ensured while the production cost is reduced by selecting the sponge lining.
[0029] Furthermore, the second support body 200 and the first support body 100 are both semicircular in shape. By arranging the second support body 200 and the first support body 100 in a semicircular shape, they can form a ring-shaped structure when assembled, and a through groove 300 is formed in the middle. When the patient lies on his side on the first support body 100, the fistula tube can pass through the through groove 300 and the fistula tube passage 250. This not only facilitates the support and fixation of the fistula tube, but also takes advantage of the patient's side-lying position.
[0030] Furthermore, a support surface 110 is provided on the first support body 100, and the support surface 110 is inclined from the top surface of the first support body 100 to its bottom surface. The setting of the support surface 110 facilitates the patient to adjust his or her side lying position, and the inclined surface supports the patient's side.
[0031] Therefore, when the patient lies on his side on the first support body 100, the fistula tube can pass through the through groove 300 and the fistula tube channel 250, which is convenient for supporting and fixing the fistula tube and avoiding discomfort to the patient due to poor drainage.
[0032] Furthermore, both ends of the first support body 100 are provided with a recess 120 , and both ends of the second support body 200 are provided with a protrusion 220 . The second support body 200 is inserted into the recess 120 through the protrusion 220 so that the second support body 200 and the first support body 100 are spliced.
[0033] In order to facilitate the splicing or separation of the first support body 100 and the second support body 200, protrusions 220 are provided at both ends of the second support body 200 and a recess 120 is provided on the first support body 100. The protrusions 220 are inserted into the recess 120 to facilitate the connection between the first support body 100 and the second support body 200. It should be noted that the protrusions 220 can be used as part of the sponge lining, or the protrusions 220 can be directly processed on the sponge lining during processing, and then covered with an outer layer to facilitate manufacturing.
[0034] It should be further explained that the protrusion 220 and the recess 120 have an interference fit, that is, the size of the protrusion 220 is slightly larger than the size of the recess 120, so that after the first support body 100 and the second support body 200 are spliced together by the protrusion 220 and the recess 120, the first support body 100 and the second support body 200 will not be easily separated.
[0035] In this embodiment, a groove body is provided at the bottom of the second support body 200, and a support split body 210 is provided in the groove body. Tube body accommodating grooves are provided on the support split body 210 and the second support body 200. The fistula tube channel 250 is formed by combining the tube body accommodating groove on the support split body 210 and the tube body accommodating groove on the second support body 200.
[0036] In order to facilitate the separation of the fistula tube from the second support body 200, the second support body 200 is divided into two other parts. When the fistula tube needs to be placed, the fistula tube is placed in the tube body receiving groove of the second support body 200, and then the support split body 210 is placed in the groove body, so that the tube body receiving groove on the support split body 210 and the tube body receiving groove on the second support body 200 form a fistula tube channel 250, and then the fistula tube is covered and fixed to support the fistula tube.
[0037] It should be noted that the support body 210 is engaged in the groove body. That is, the support body 210 is installed in the groove body by engaging, which is convenient for installation and further convenient for taking and placing the fistula tube.
[0038] Furthermore, a support tube body is disposed within the fistula tube passage 250. The support tube body comprises a second half tube 240 and a first half tube 230. The second half tube 240 and the first half tube 230 are respectively disposed within the tube housing grooves of the support body 210 and the second support body 200. Since the second support body 200 is lined with sponge and is easily deformed by external pressure, to prevent the fistula tube from being compressed by deformation of the second support body 200, thereby preventing drainage by the fistula tube, the first half tube 230 and the second half tube 240 are disposed within the tube housing groove. When the support body 210 is installed, the first half tube 230 and the second half tube 240 are spliced together to form the support tube body. This prevents simultaneous deformation of the fistula tube when the second support body 200 is compressed and deformed, thereby ensuring safe use and smooth drainage.
[0039] Furthermore, a flow drainage monitor is provided in the fistula tube channel 250, and the flow drainage monitor is used to monitor the amount of fluid flowing through the fistula tube.
[0040] By setting a flow drainage monitor in the fistula tube channel 250, when the fistula tube is installed, the flow drainage monitor is installed on the fistula tube to monitor the amount of fluid in the fistula tube in real time. When the preset threshold of the flow drainage monitor is exceeded, an alarm will be generated. For example, the flow drainage monitor is set to 100ml / h, and when the monitoring value of the flow drainage monitor exceeds 100ml / h, an alarm will be generated.
[0041] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
