Description

Catheter fixation device for human body

This invention relates to a catheter fixing device, and in particular to a catheter fixing device for use in a human body.

Due to the need for medical treatment of diseases, patients sometimes need to have a drainage catheter placed on their bodies. One end of the catheter is inserted into the patient's body, and the other end of the drainage tube is attached to the patient and connected to a drainage bag, which can hold the body fluids, blood or pus to be drained. Since drainage or infusion takes a long time, the patient may need to move during this period. When the patient moves, it is easy to pull the drainage catheter, causing pain, or pull the insertion end of the catheter, causing the catheter to slip; and when the patient needs to get out of bed and move, he or she also needs to hold the drainage catheter in his or her hand, causing inconvenience in use.

Existing drainage catheters are too long and difficult to fix on the body, which is not conducive to patient movement. The human body insertion end of the catheter is easily pulled by the patient's movement, causing pain or slippage. The present invention provides a catheter fixing device for the human body, which can solve the problems caused by the existing drainage or infusion catheters.

In this way, when the patient moves, the human body insertion end of the catheter will not be pulled, and when the patient gets out of bed and moves, the patient does not need to hold the catheter frequently, thereby solving the problems of pain, discomfort or inconvenience in movement caused by the existing drainage or infusion catheter.

Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a three-dimensional view of a catheter fixing device 1 for a human body HB, and FIG. 2 is a plan view of the catheter fixing device 1 for a human body in an extended state. In this embodiment, the catheter fixing device 1 includes a band-shaped elastic member 10, a buckle member 20, a first adhesive member 30, and a second adhesive member 40. The band-shaped elastic member 10 can be wrapped around various parts of the human body, such as the trunk or limbs. To facilitate such use, the band-shaped elastic member 10 is long and flat and has a certain degree of stretchability. In some embodiments, the band-shaped elastic member 10 can be a textile, such as but not limited to an elastic bandage. The strip-shaped elastic member 10 includes a plurality of buckle portions 11 arranged along the length direction LD, and two adjacent buckle portions 11 are spaced apart from each other in the length direction LD. In this embodiment, the buckle member 20 is disposed at one end of the strip-shaped elastic member 10 in the length direction LD, and the buckle member 20 is configured to be buckled and fixed with any buckle portion 11, so that the strip-shaped elastic member 10 forms a ring shape.

Please refer to Fig. 3, which is a schematic diagram of the catheter fixing device 1 for human body HB being mounted on human body HB. By the buckle 20 and different buckle parts 11 being buckled and fixed to each other, the size of the ring structure formed by the band-shaped elastic member 10 can be adjusted, so that it can be adaptively mounted on different parts of human body HB.

As shown in FIG. 1 and FIG. 2 , in this embodiment, the first adhesive member 30 is disposed at one end of the strip-shaped elastic member 10 close to the buckle member 20; the second adhesive member 40 is disposed at one end of the strip-shaped elastic member 10 away from the buckle member 20. For example, the strip-shaped elastic member 10 can be divided into a first section and a second section connected to each other in the length direction LD, the head end of the first section is provided with the buckle member 20, the end of the first section is connected to the second section, the first adhesive member 30 is disposed in the first section, and the second adhesive member 40 is disposed in the second section.

As shown in FIG. 1 and FIG. 2 , in some embodiments, the buckle parts 11 are located between the first adhesive part 30 and the second adhesive part 40 in the length direction LD of the strip-shaped elastic member 10. In some embodiments, the buckle parts 11 are disposed in the second section; in some embodiments, the buckle parts 11 are disposed in the first section and the second section. In some embodiments, the buckle parts 11 are multiple through holes penetrated in the strip-shaped elastic member 10, and the buckle part 20 is a button sewn on the strip-shaped elastic member 10.

As shown in FIGS. 1 to 3 , in this embodiment, the second adhesive 40 is configured to be bonded to the first adhesive 30, so that the catheter TB is clamped between the first adhesive 30 and the second adhesive 40. In some embodiments, the first adhesive 30 and the second adhesive 40 are Velcros corresponding to each other. When in use, the catheter TB can be placed between the first adhesive 30 and the second adhesive 40, and the first adhesive 30 and the second adhesive 40 are bonded to each other, so that the catheter TB is clamped between the two Velcros, thereby fixing the catheter TB.

As shown in FIG. 1 and FIG. 2 , in this embodiment, the catheter fixing device 1 further includes a sheet substrate 50, which is disposed on the band-shaped elastic member 10 and is located between the buckle member 20 and the first adhesive member 30. When the band-shaped elastic member 10 is fixed around the human body, the sheet substrate 50 can correspond to the position of the catheter insertion end and press on or near the catheter insertion end. For example, a butterfly patch is used to directly attach the catheter to the skin near the catheter insertion end, and the sheet substrate 50 can cover the butterfly patch to avoid discomfort caused by friction; or, during infusion, the catheter will continue to be inserted into the skin, and the sheet substrate 50 can cover and press the catheter to prevent the catheter from shaking or displacement.

In some embodiments, the sheet substrate 50 includes a first substrate 51 and a second substrate 52 stacked on each other, the first substrate 51 and the second substrate 52 are connected to each other on opposite sides of the width direction WD of the strip-shaped elastic member 10, and the strip-shaped elastic member 10 is inserted between the first substrate 51 and the second substrate 52 along its length direction LD. In the width direction WD, the width of the sheet substrate 50 is greater than the width of the strip-shaped elastic member 10. In some embodiments, the sheet substrate 50 is a breathable textile. In some embodiments, the first substrate 51 and the second substrate 52 are gauze, for example, the sheet substrate 50 is a piece of gauze folded into the first substrate 51 and the second substrate 52, and openings are made at the connection points of the opposite sides of the first substrate 51 and the second substrate 52 along the length direction LD of the strip-shaped elastic member 10, so that the strip-shaped elastic member 10 can pass through the openings on both sides. In some embodiments, the elasticity or stretchability of the sheet substrate 50 is less than that of the strip-shaped elastic member 10, so as to better press the catheter insertion end or the position adjacent to the catheter insertion end.

In some embodiments, the first adhesive member 30 is a thorny surface of Velcro, and the second adhesive member 40 is a fleece surface of Velcro. The first adhesive member 30 is disposed on a surface of the band-shaped elastic member 10 that does not contact the human body, and the second adhesive member 40 is disposed on another surface of the band-shaped elastic member 10 that contacts the human body. In some embodiments, the band-shaped elastic member 10 includes a first surface 101 and a second surface 102 that are opposite to each other, the first surface 101 is configured to face away from the human body, and the second surface 102 is configured to face the human body, the first adhesive member 30 is disposed on the first surface 101, and the second adhesive member 40 is disposed on the second surface 102.

When a patient uses a drainage or infusion device and the catheter fixing device 1, the elastic band 10 can be wrapped around an appropriate part of the human body, and the second surface 102 of the elastic band 10 will contact the skin. Since the second adhesive member 40 of the second surface 102 is the hairy surface of Velcro, even if the hairy surface of Velcro touches the skin, it is not easy for the patient to feel uncomfortable. Next, according to the size of the human body part around which the elastic band 10 is wrapped, the buckle 20 is buckled to the appropriate buckle portion 11, so that the elastic band 10 can be slightly tightly mounted on the human body part; at the same time, the position of the catheter is adjusted so that a part of the catheter can be clamped between the first adhesive member 30 and the second adhesive member 40, so that the catheter can be fixed; and at the same time, the sheet substrate 50 can be aligned and pressed against the catheter insertion end or the position adjacent to the catheter insertion end.

As shown in FIG. 2 , in some embodiments, the buckle parts 11 are arranged with a first length D1 along the length direction LD of the strip-shaped elastic member 10, and the first adhesive member 30 or the second adhesive member 40 extends with a second length D2 along the length direction LD of the strip-shaped elastic member 10, and the second length D2 is greater than or equal to the first length D1. In some embodiments, the second length D2 is greater than the first length D1. In this way, no matter which buckle part 11 the buckle 20 is buckled to, a certain degree of overlapping bonding can be left between the first adhesive member 30 and the second adhesive member 40, so that the catheter can be well clamped at the overlapping bonding between the first adhesive member 30 and the second adhesive member 40.

In summary, the catheter fixing device for the human body of each embodiment of the invention can be applied to a catheter for drainage or infusion. The band-shaped elastic member can form a ring structure with adjustable size, which can be adaptively mounted on the required part of the human body, and at the same time, the catheter can be clamped between the first adhesive member and the second adhesive member, and the human body insertion end of the catheter can also be pressed by the sheet substrate. In this way, when the patient moves, the human body insertion end of the catheter will not be pulled, and when the patient gets out of bed and moves, the patient does not need to hold the catheter frequently; the sheet substrate 50 also does not prevent skin friction or displacement of the catheter needle. Thus, the problems of pain, discomfort or inconvenience in movement caused by the existing drainage or infusion catheter are solved.
