Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a non-stick catheter fixing device. Background Art

[0002] Deep vein catheterization is a treatment method of inserting a catheter into a deep large vein and central vein through a relatively superficial vein. Deep vein catheterization can reduce the number of times of puncturing the vein by a venous syringe, which is beneficial to protecting the patient's skin, reducing puncture pain, and can also reduce the stimulation of drugs to blood vessels, facilitating drug absorption. It is very suitable for patients who need long-term infusion or have relatively serious conditions. Currently, for the fixation of deep vein catheters, clinical practice often uses film dressing or SecurAcath, which inevitably causes tearing and damages the skin.

[0003] Chinese Patent Publication No.: CN209864946U, discloses a catheter fixing band, including a fixing band main body, a first airbag and a second airbag. The outer surface of the fixing band main body is provided with a non-woven fabric layer, and a filling layer is filled inside the non-woven fabric layer. The first airbag is arranged inside the filling layer. The second airbag is installed on the back of the fixing band main body, and an interface is fixed at the middle position of the second airbag. The first airbag can help the user relieve the pressure on the neck, which is beneficial to preventing the harm caused by the long-term fixation of the fixing band to the patient's neck. The two sides of the fixing band main body are installed with a first elastic band and a second elastic band, which is beneficial to enhancing the elastic performance of the whole fixing band, so that the fixing band can be conveniently used by obese and thick-necked patients. The second buckle and the second tooth as well as the first buckle and the first tooth are fixed by a clamping action to avoid falling off. However, the above device has the following defects in use:

[0004] 1. Using the clamping action of the buckle and the tooth to fix the device has high manufacturing difficulty and precision, and the manufacturing cost is also higher;

[0005] 2. The device fixes the catheter by fitting the fixing band to the patient's body surface, which is only applicable to rigid catheters. Otherwise, it will squeeze the catheter, affecting the treatment effect, with a small scope of application, and will also affect the patient's comfort. At the same time, the catheter lacks a structure for limiting and restraining, and the catheter will shake or displace. Content of the Utility Model

[0006] The technical problem to be solved by the present utility model is that the manufacturing difficulty and precision of the existing fixing device are high, which increases the production cost. At the same time, the applicable range is small, affecting the comfort of patients, and there is a lack of restraint on the catheter. In view of the above problems, a non-sticky catheter fixing device is proposed, which includes a fixing band and a fixing seat. The fixed end of the fixing band is connected to the fixed end of the fixing seat. A plurality of buckles are arranged on the outer surface of the fixing band near the movable end. The inner surface of the end of the movable end of the fixing band is provided with a hook-and-loop fastener sub-surface, and the outer surface of the fixing band is provided with a hook-and-loop fastener mother-surface. An airbag is arranged on the inner surface of the fixing band. The connecting end of the fixing seat is provided with a hook for connecting with the buckle, a through-hole for passing the fixing band is arranged on the fixing seat, and a pipe support buckle for fixing the catheter is arranged in the middle of the upper surface of the fixing seat.

[0007] According to the technical solution of the present utility model, by setting the structure of the through-hole, the fixing band passes through the through-hole after surrounding a circle and is fixed by the hook-and-loop fastener, so that the fixing band is fixed in a ring shape on the patient's body surface. The structure is simple, the use is convenient, the manufacturing difficulty and cost are relatively low, and the fixing band passing through the through-hole covers the catheter above, which can further restrain the catheter and prevent it from falling off from the pipe support buckle. By setting the structure of the pipe support buckle, the catheter is clamped and fixed to avoid the shaking and displacement of the catheter, and reduce the risk of catheter disconnection caused by accidents. By setting the structure of the hook and the buckle, the hook is connected with different buckles to initially adjust the ring size of the fixing band to adapt to different people, and then the ring-shaped fixing band is further supported by the airbag, which can not only fix the fixing band tightly, but also avoid pressure sores caused by long-term use.

[0008] Preferably, there is a certain distance between the movable end of the fixing band and the nearest buckle. The movable end of the fixing band passes through the lower part of the through-hole and is fixed by the hook-and-loop fastener.

[0009] Preferably, the through-hole is arranged between the pipe support buckle and the hook.

[0010] Preferably, the width of the fixing band is smaller than the width of the fixing seat, and the width of the fixing band is larger than the width of the hook.

[0011] Preferably, the cross-section of the pipe support buckle is a circle, and a notch is opened at the top.

[0012] Preferably, the airbag is arranged on the inner surface between the buckle far from the movable end and the fixed end of the fixing band.

[0013] Preferably, the hook-and-loop fastener mother-surface is arranged on the outer surface between the buckle far from the movable end and the fixed end of the fixing band.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] The technical solution of the present utility model is that through the structure of the through hole, the fixing belt passes through the through hole after surrounding a circle, and is fixed by sticking with Velcro, so that the fixing belt is fixed in a ring shape on the patient's body surface. The structure is simple, the use is convenient, the manufacturing difficulty and cost are relatively low, and the fixing belt passing through the through hole covers the catheter above, which can further restrain the catheter and prevent it from falling off from the pipe support buckle; through the structure of the pipe support buckle, the catheter is clamped and fixed, preventing the catheter from shaking and displacing, and reducing the risk of the catheter being accidentally removed; through the structure of the hook and the buckle, by connecting the hook with different buckles, the ring size of the fixing belt is initially adjusted to adapt to different people, and then the ring-shaped fixing belt is further supported by the airbag, which can not only make the fixing belt fixed tightly, but also avoid pressure sores caused by long-term use.

[0019] Next, the technical solutions in the embodiments of the present utility model will be described in detail in conjunction with the attached Figure 1-2 , of the present utility model. Embodiment 1

[0020] As Figure 1-2 shown, the present utility model is a non-stick catheter fixing device, including a fixing belt 1 and a fixing seat 2.

[0021] One end of the fixing belt 1 is a fixed end, and the other end is a movable end. The inner side thereof is made of cotton, which can increase the comfort of the patient when contacting the patient's body surface. A plurality of buckles 11 are evenly arranged on the outer surface of the movable end of the fixing belt 1, and both ends of the buckle 11 are fixedly connected to the surface of the fixing belt 1 by sewing.

[0022] A Velcro sub-surface 41 is arranged on the inner side of the end of the movable end of the fixing belt 1, and a Velcro mother-surface 42 is arranged on the outer side of the fixed end of the fixing belt 1. Both the Velcro sub-surface 41 and the Velcro mother-surface 42 are connected to the fixing belt 1 by sewing. Among them, the length of the Velcro mother-surface 42 is much greater than the length of the Velcro sub-surface 41, and the fixing position of the Velcro sub-surface 41 on the Velcro mother-surface 42 can be adjusted according to the actual situation.

[0023] The fixed end of the fixing belt 1 is connected to the fixed end of the fixing seat 2. The specific connection method is as follows: An elongated groove is recessed in the fixed end of the fixing seat 2. The end of the fixing belt 1 passes through the elongated groove and fits with other parts of the fixing belt 1, and is fixed by sewing, so that the fixing belt 1 is connected to the fixing seat 2.

[0024] Therefore, the width of the fixing belt 1 is smaller than the width of the fixing seat 2, so that the fixing belt 1 can pass through the elongated groove.

[0025] The connecting end of the fixing seat 2 is opposite to the fixed end. A hook 23 is provided at the connecting end. The hook 23 is connected to the buckle 11. By connecting the hook 23 to different buckles 11, the size of the loop formed by the fixing belt 1 can be adjusted to suit different patients, and the applicable range is wide.

[0026] A pipe support buckle 21 is arranged at the middle position of the upper surface of the fixing seat 2. The cross-section of the pipe support buckle 21 is a circular ring, and a notch is opened at the top of the circular ring. The notch of the pipe support buckle 21 is enlarged through elastic deformation so that the catheter can be snapped into it. After recovery, the catheter is restricted by the pipe support buckle 21 and is not easily disengaged from the pipe support buckle 21.

[0027] A through hole 22 is arranged on the fixing seat 2 between the pipe support buckle 21 and the hook 23. After the hook 23 is connected to the buckle 11, there is an extra part at the movable end of the fixing belt 1. The extra part passes through the through hole 22 and covers above the pipe support buckle 21, and then is fixed by Velcro. At this time, the extra part will neither pull with others, and at the same time, it can further restrict the catheter to prevent the catheter from disengaging from the pipe support buckle 21.

[0028] The width of the fixing belt 1 is greater than the width of the hook 23, so that the hook 23 can be smoothly connected to the buckle 11.

[0029] There is a certain distance between the buckle 11 at the movable end of the fixing belt 1 and the end of the movable end, ensuring that even when the hook 23 is connected to the buckle 11 closest to the end of the movable end, there is still an extra part at the movable end of the fixing belt 1, which can pass through the through hole 22.

[0030] The fixing seat 2 is an integral structure, made of silica gel material, having a certain elasticity, and the whole is in a certain arc. Therefore, when fixing, it can fit well with the patient's body surface, making the fixing tight. A cushion layer can be adhesively provided on the inner side of the fixing seat 2 to improve the comfort of the patient.

[0031] An airbag 3 is also arranged on the inner side of the fixing belt 1. The airbag 3 is located between the buckle 11 and the fixed end. After the fixing belt 1 is initially fixed by connecting the hook 23 to the buckle 11, by inflating the airbag 3, the fixing belt 1 can be further propped up, making the fixing belt 1 fixed tightly and preventing it from falling off. During use, the pressure at the fixing position can be relieved by deflating and then inflating the airbag 3 regularly to avoid pressure sores.

[0032] The usage method of a non-sticky catheter fixing device in this embodiment is as follows:

[0033] First, pass the movable end of the fixing band 1 through the lower part of the through hole 22 of the fixing base 2, so that the movable end of the fixing band 1 extends out of the fixing base 2 and is located outside it. At this time, the fixing band 1 and the fixing base 2 form an annular band. Put this annular band on the position to be fixed, and make the catheter located outside the annular band. According to the actual situation of the patient and the fixing part, hook the hook 23 into the corresponding buckle 11 to preliminarily fix the fixing band 1. Then, snap the catheter into the pipe support buckle 21 on the fixing base 2, and cover the fixing band 1 located outside the fixing base 2 above the fixing base 2. Through the magic tape, bond the movable end of the fixing band 1 to the outer surface of the fixing band 1.

[0034] Then, inflate the airbag 3 to further prop up the fixing band 1, so that the fixing band 1 fits closely with the patient's body surface, preventing it from slipping as a whole due to loose fixation. Regularly deflate the airbag 3 to relieve the pressure on the fixed part, and it can also prevent pressure sores caused by long-term pressure. After deflating for a period of time, it needs to be inflated again to ensure the normal operation of the device. The specific time depends on the instructions of the medical staff.

[0035] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any changes made on the basis of the technical solution according to the technical idea proposed by the present invention fall within the protection scope of the present invention.
