Description

Technical Field

[0001] The utility model relates to the technical field of dialysis tube fixing, in particular to a dialysis tube fixing device. Background Art

[0002] Dialysis tube is a medical device required by patients with kidney disease. It can exchange substances with dialysate in vitro through the catheter connecting the kidney and dialysate, remove metabolic waste from the body of the dialysis patient, and maintain the electrolyte and acid-base balance in the patient's body. Commonly used kidney dialysis tubes in clinical practice mainly include removable dialysis tubes, end-to-side dialysis tubes, double-connected tubes, three-lumen tubes, etc.

[0003] At present, a common way to fix a dialysis tube is to fix the needle tip of the dialysis tube on the arm with medical tape. In order to prevent the dialysis tube from being dragged loose due to gravity or other reasons, resulting in displacement of the needle insertion site, the dialysis tube needs to be fixed for a second time so that the position of the dialysis tube and the arm are relatively fixed to prevent the dialysis tube from loosening. The existing secondary fixing method is to leave a certain length of the dialysis tube, then coil it randomly, and then fix it on the patient's clothes with hemostatic forceps. The operation is very inconvenient, and the fixing method is not reliable and there is a risk of falling off. Therefore, a dialysis tube fixing device is proposed. Utility Model Content

[0004] The utility model is a dialysis tube fixing device proposed to solve the shortcomings in the prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dialysis tube fixing device, comprising a shell, and fixing components are installed on both sides of the outer surface of the shell; a column is fixedly installed on the top side of the shell, and four arc-shaped grooves are evenly opened on one side of the outer surface of the column, and the inner walls of the four arc-shaped grooves are opened with air grooves, and the opening edges of the four air grooves are fixedly connected with fixed air bags; a distribution air flow duct is commonly provided between the multiple air grooves; an inflation component is installed inside the shell, and the inflation component is connected to the distribution air flow duct; an exhaust component is fixedly installed on one side of the outer surface of the column, and the exhaust component is connected to the distribution air flow duct.

[0006] Furthermore, the fixing assembly includes a fixing frame and a matching elastic band, and the fixing frame and the elastic band are symmetrically fixed on the outer walls of both sides of the shell, and a Velcro hook surface and a Velcro fleece surface are fixedly installed on one side of the outer surface of the elastic band, which is convenient for fixing the shell on the patient's arm.

[0007] Furthermore, the air distribution channel includes a direct current channel, and the direct current channel is opened inside the column. A through hole is opened between the direct current channel and adjacent air grooves, which is conducive to the gas in the direct current channel entering each air groove.

[0008] Furthermore, the inflation component includes a micro air pump, and the micro air pump is fixedly installed on the inner bottom of the shell. A fixed tube is fixedly passed through the output end of the micro air pump, and the fixed tube passes through the shell and is fixedly connected to the column. The fixed tube is connected to the direct current channel to facilitate air supply to the direct current channel.

[0009] Furthermore, the exhaust assembly includes an exhaust pipe, and the exhaust pipe is fixedly mounted on an outer wall of one side of the column and is connected to the direct current channel. The inner surface of the exhaust pipe is threadedly connected with a plug, which can block the exhaust pipe to prevent gas from being discharged through the exhaust pipe during inflation.

[0010] Furthermore, an exhaust hole is provided on one side of the bottom of the exhaust pipe, and gas can be discharged through the exhaust hole to avoid completely unscrewing the screw plug.

[0011] Furthermore, a plurality of air inlet holes are provided on the top of the shell, which facilitates the entry of gas into the shell.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the dialysis tube fixing device, through the arranged fixing components, arc-shaped grooves, columns, air grooves, air bags, air distribution flow channels, exhaust components and inflation components, when fixing the dialysis tube, first fix the columns on the patient's arm, and then place the dialysis tube in the arc-shaped groove, and fix it evenly by the air bag. The fixing method is simple and firm, and the dialysis tube is not easy to fall off. At the same time, the air bag is used for evenly squeezing and fixing, which can reduce the influence on the inner diameter of the dialysis tube, and ensure that a large blood flow can be maintained in the dialysis tube, thereby ensuring smooth blood flow.
