Description

Technical Field

[0001] The utility model relates to the technical field of catheter fixators, in particular to a catheter fixator. Background Art

[0002] Anesthesia indwelling catheters are often used during surgeries. When an anesthetic injection is needed before the start of the surgery, the syringe needle is withdrawn, and the anesthesia indwelling catheter is left in the body to facilitate continuous anesthesia injection. Since part of the anesthesia indwelling catheter remains in the body, if it is not fixed during the surgery, the catheter may move out, resulting in the deviation of the anesthetic site and causing infection at the wound.

[0003] For the existing anesthesia catheters during fixation, a sheet-shaped sponge that can adhere to the skin is added at the wound. During use, the catheter is displaced to the center through the notch of the sheet-shaped sponge. This method reduces the problems of easy infection and easy displacement. However, during the surgery, the patient's position may need to be moved. Since the length of the catheter is fixed, it is rather troublesome to move the patient's position, and the catheter may still move out, causing infection. Therefore, we propose an anesthesia catheter fixator. Summary of the Utility Model

[0035] Embodiment 1

[0036] As Figures 1-3As shown in the figure, the present utility model provides a technical solution: a catheter fixator, which includes an adhesive sponge 1. At the top of the adhesive sponge 1, a fixed base 2 is adhesively connected. The fixed base 2 can be adhesively fixed to the adhesive sponge 1. An installation groove 201 is formed inside the fixed base 2. On the inner bottom surface of the installation groove 201, a plurality of guiding blocks 202 are installed. The guiding blocks 202 and the guiding grooves 203 are used for receiving and guiding the catheter. A guiding groove 203 is formed between the guiding blocks 202. An outlet groove 204 is formed on the outer side wall of the guiding block 202. At the top of the fixed base 2, a fixed cover plate 3 is provided. On the outer side wall of the fixed cover plate 3, an upper fixing block 301 is installed. Inside the upper fixing block 301, a sliding groove 302 is formed. The inside of the sliding groove 302 extends to the bottom of the upper fixing block 301 and is provided with a fixing plate 303. The fixing plate 303 can slide inside the sliding groove 302. On the outer side wall of the fixed base 2, corresponding to the position of the upper fixing block 301, a lower fixing block 205 is installed. At the top of the lower fixing block 205, corresponding to the position of the fixing plate 303, a fixing groove 206 is formed. The fixing plate 303 can be stuck inside the fixing groove 206.

[0037] Embodiment 2

[0038] As Figures 1-3 shown, the fixed base 2, the guiding blocks 202 and the fixed cover plate 3 are all made of silicone material. The fixed base 2, the guiding blocks 202 and the fixed cover plate 3 made of silicone material will not cause harm to the human body and are relatively safe during use.

[0039] The upper fixing block 301 and the lower fixing block 205 are both made of plastic material. The upper fixing block 301 and the lower fixing block 205 made of plastic material have high enough strength and can be more stable when helping to fix the fixed base 2 and the fixed cover plate 3.

[0040] The guiding groove 203 is adapted to the external catheter, and the outlet groove 204 is adapted to the external catheter. By the adaptation of the guiding groove 203 to the external catheter and the adaptation of the outlet groove 204 to the external catheter, it is more convenient for the staff to place the external catheter.

[0041] A hinge 207 is provided between the back surfaces of the fixed base 2 and the fixed cover plate 3, so that the fixed base 2 and the fixed cover plate 3 are hinged. By the hinge connection between the fixed base 2 and the fixed cover plate 3, it is more convenient for the fixed base 2 and the fixed cover plate 3 to be opened.

[0042] On the outer side wall of the fixed base 2, corresponding to the position of the outlet groove 204, an inlet pipe opening 208 is formed. The inner bottom surface of the installation groove 201 extends to the bottom of the adhesive sponge 1 and is provided with an outlet pipe opening 209. The external catheter can be inserted through the inlet pipe opening 208, and the external catheter can extend out through the outlet pipe opening 209.

[0043] The upper fixing block 301 is adapted to the lower fixing block 205, and the fixing plate 303 is adapted to the fixing groove 206. By the adaptation of the upper fixing block 301 to the lower fixing block 205 and the adaptation of the fixing plate 303 to the fixing groove 206, when the fixing plate 303 is inserted into the interior of the fixing groove 206, the upper fixing block 301 and the lower fixing block 205 can be fixed.

[0044] A telescopic rod 304 is arranged between the inner side wall of the sliding groove 302 and the fixing plate 303. A return spring 305 is sleeved on the periphery of the telescopic rod 304. The telescopic rod 304 is adapted to the sliding groove 302, and the return spring 305 is adapted to the sliding groove 302. Through the design of the telescopic rod 304 and the return spring 305, the return spring 305 and the telescopic rod 304 can push the fixing plate 303 to fix the upper fixing block 301 and the lower fixing block 205.

[0045] A clamping groove 306 is formed on the front surface of the fixing plate 303. A clamping spring 210 is fixed on the inner side wall of the fixing groove 206 corresponding to the clamping groove 306. The clamping spring 210 is adapted to the clamping groove 306. When the clamping spring 210 is inserted into the interior of the clamping groove 306, the fixing plate 303 and the fixing groove 206 can be fixed.

[0046] A pressing button 307 is arranged on the front surface of the fixing plate 303 and extends to the front surface of the upper fixing block 301 inside the sliding groove 302. An activity groove 308 is formed at the bottom of the upper fixing block 301 corresponding to the fixing plate 303. The design of the pressing button 307 can make it more convenient to open the fixing cover plate 3 when needed, and the design of the activity groove 308 can make the displacement of the fixing plate 303 more convenient.

[0047] In addition, it should be noted that the catheter fixator mentioned in this technical solution can be used for fixing anesthetic catheters, and can also be used for fixing catheters involved in catheter insertion into the body for drug infusion or drainage, such as pleural effusion drainage and cranial drainage.

[0048] The working process of the utility model: Taking it as an example of an anesthesia catheter fixator, when using the anesthesia catheter fixator, first, the staff can press the pressing button 307 to drive the fixing plate 303 to displace towards the back. At this time, the clamping spring 210 will separate from the clamping groove 306, so that the fixing plate 303 can be separated from the fixing groove 206. Due to the design of the hinge 207, the staff can very conveniently open the fixing cover plate 3, and then can take out the anesthesia catheter placed inside the guiding groove 203, and the taken-out part of the anesthesia catheter extends out through the catheter outlet groove 204. The extended anesthesia catheter is sent out from the catheter inlet 208 to change the length of the anesthesia catheter. After the anesthesia catheter is sent out, the staff can close the fixing cover plate 3. When the fixing cover plate 3 is closed, the telescopic rod 304 and the return spring 305 will reset, so that the clamping spring 210 can be stuck inside the clamping groove 306 to re-complete the fixed installation of the anesthesia catheter. Compared with the existing anesthesia catheter fixator, it can well fix the anesthesia catheter, and the fixed anesthesia catheter can be extended according to actual needs, so that the catheter will not be displaced due to the length reason after the patient changes the position, reducing the risk of infection.

[0049] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
