Description

Technical Field

[0001] The utility model relates to the technical field of drainage catheters, in particular to an extracorporeal auxiliary supporting device for drainage catheters. Background Art

[0002] Drainage catheters are medical devices used for clinical surgical drainage. They guide pus, blood, and fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and promote wound healing. There are many types of surgical drainage catheters used clinically, some are used for urinary catheterization, some are used for wounds, and they are used in the chest cavity, brain cavity, gastrointestinal tract, bile duct, etc. The purpose of surgical drainage is to guide pus, blood, and fluids accumulated between human tissues or in body cavities to the outside of the body to prevent postoperative infection and affect wound healing.

[0003] The existing abdominal drainage catheter needs to be fixed when in use. At present, medical staff generally use tape to stick to the abdominal drainage catheter, and then stick the tape to clothes or skin, etc., to fix the abdominal drainage catheter. However, the effect of fixing the drainage catheter with tape is not good, which will cause the drainage catheter to move, loosen and fall off easily. Utility Model Content

[0009] The catheter fixing locking sleeve part comprises a base plate and an airbag ring embedded in the base plate. The detachable pressure cover on the upper end of the base plate has a pressure cover member for pressing the outer ring of the airbag ring.

[0010] In a specific embodiment, the patch is a PU waterproof patch, an opening for inserting a catheter is provided in the middle of the patch, a first separation port is provided on one side of the patch, and the first separation port is connected to the opening.

[0011] In a specific embodiment, the cotton pad portion is a ring-shaped sterile cotton pad, and a second separation opening is opened on one side of the cotton pad portion, and the second separation opening is communicated with the ring opening of the cotton pad portion.

[0012] In a specific embodiment, the base plate, the airbag ring and the gland member are all provided with a third separation opening.

[0013] In a specific embodiment, the base plate includes a bottom ring piece and a socket fixedly connected to the upper end surface of the bottom ring piece for connecting the gland piece;

[0014] The upper end surface of the socket is provided with a groove, and the outer ring of the airbag ring extends into the groove.

[0015] In a specific embodiment, the pressure cover member includes an annular cover and a pressure ring seat fixedly connected to the lower end surface of the annular cover, and the pressure ring seat is pressed into the groove.

[0033] Reference Figure 1-4 As shown, the utility model provides an extracorporeal auxiliary support device for a drainage catheter, comprising:

[0034] The patch 100 is used for being applied on the skin of a patient;

[0035] A cotton pad portion 200, which is placed on an opening of a patient for inserting a catheter;

[0036] The catheter fixing locking sleeve part 300 includes a base plate 310 and an airbag ring 320 embedded in the base plate 310 . The detachable pressure cover on the upper end of the base plate 310 has a pressure cover member 330 for pressing the outer ring of the airbag ring 320 .

[0037] The airbag ring 320 is embedded in the base plate 310, and the pressure cover 330 is detachably pressed on the upper end of the base plate 310. When the drainage catheter is assisted in fixation, the cotton pad part 200 is put on the catheter and cushioned at the opening of the patient for inserting the catheter, and then the catheter fixing locking sleeve part 300 is put on the drainage catheter, so that the base plate 310 is pressed on the cotton pad part 200. After the pressure cover 330 is pressed on the base plate 310, the outer ring of the airbag ring 320 is squeezed so that the inner ring of the airbag ring 320 squeezes and locks the drainage catheter. Finally, the catheter fixing locking sleeve part 300 is applied to the patient's skin through the patch 100, which can effectively assist in fixing and supporting the drainage catheter, prevent the drainage catheter from moving, and prevent the drainage catheter from loosening and falling off.

[0038] As a further preference of the above embodiment, the patch 100 is a PU waterproof patch, and an opening 110 for fitting a catheter is provided in the middle of the patch 100, and a first separation port 120 is provided on one side of the patch 100, and the first separation port 120 is connected to the opening 110.

The second separation port 210 is connected to the ring port of the cotton pad portion 200. The cotton pad portion 200 can absorb the exudate at the opening of the patient's catheter for inserting, and can also prevent the catheter fixing locking sleeve portion 300 from directly contacting the skin, thereby improving the comfort during use.

[0040] The base plate 310 , the airbag ring 320 and the gland member 330 are all provided with a third separation opening 301 .

[0041] As a further preferred embodiment of the above embodiment, the base plate 310 includes a bottom ring piece 311 and a socket 312 fixedly connected to the upper end surface of the bottom ring piece 311 and used for connecting the gland member 330;

[0042] A groove 302 is formed on the upper end surface of the plug socket 312 , and the outer ring of the airbag ring 320 extends into the groove 302 .

[0043] As a further preferred embodiment of the above embodiment, the pressure cover member 330 includes an annular cover 331 and a pressure ring seat 332 fixedly connected to the lower end surface of the annular cover 331 , and the pressure ring seat 332 is pressed into the groove 302 .

[0044] Furthermore, the inner ring surface of the pressure ring seat 332 is provided with an inclined surface, so that when the pressure ring seat 332 is pressed into the groove 302 , the inclined surface can be pressed in better and can squeeze the outer ring of the airbag ring 320 .

[0045] When the gland member 330 is pressed onto the base plate 310, the pressure ring seat 332 of the gland member 330 is pressed into the groove 302, and the inner ring of the pressure ring seat 332 presses against the outer ring of the airbag ring 320, so that the inner ring of the airbag ring 320 presses and locks the drainage catheter, thereby achieving auxiliary fixation of the drainage catheter.

[0046] Preferably, the base plate 310 and the pressure cover member 330 are both made of plastic material.

[0047] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
