Description

Technical Field

[0001] The utility model relates to the technical field of medical accessories, in particular to a fixing belt, an indwelling needle fixing device and a catheter fixing device. Background Art

[0002] Intravenous infusion is a common medical treatment method, widely used in the treatment and care of various diseases. Intravenous infusion usually requires the use of an infusion tube. The left side of the infusion tube is connected to a medicine bag, and the right side is connected to a needle. During infusion, the medicine is injected into the medicine bag, and then the needle is punctured into the patient's back vein to achieve intravenous infusion. In order to prevent the needle from shifting or even detaching from the patient's back vein, medical staff usually use tape to stick the part of the infusion tube near the puncture site to the patient's arm to fix the infusion tube.

[0003] However, in actual use, the inventors found that the method of fixing with adhesive tape still has some shortcomings, specifically:

[0004] For young patients, they are usually active and may tear the tape or pull the catheter intentionally or unintentionally, causing the movement of the catheter and the needle, resulting in displacement or even falling off of the needle, causing redness, swelling and pain at the puncture site, and even phlebitis, which increases the patient's pain and is not conducive to the treatment of the patient. Therefore, for young patients, medical staff usually wrap the tape tighter so that the catheter can be fixed more stably to reduce the risk of needle displacement or falling off. However, tighter tape wrapping increases the pressure of the catheter on the patient's skin. In particular, for patients using indwelling needles, long-term pressure causes pressure damage to the patient's skin, causing secondary injury to the patient, which is also not conducive to the treatment of the patient.

[0005] Therefore, based on the above-mentioned shortcomings, there is an urgent need to design a fixing belt, an indwelling needle fixing device and a catheter fixing device. Utility Model Content

[0006] The purpose of the utility model is to provide a fixing belt, an indwelling needle fixing device and a catheter fixing device to address the above-mentioned drawback that the method of fixing the catheter with adhesive tape in actual use causes pressure injury to the patient's skin.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] A fixing belt, comprising a belt body, wherein a first through hole and a second through hole are arranged on the left side of the belt body, the first through hole and the second through hole are arranged along the length direction of the belt body, the right side of the belt body can pass through the first through hole or the second through hole to form the belt body into a ring, and a convex ridge is arranged on the right side of the belt body;

[0009] When the right side portion of the belt body passes through the first through hole or the second through hole, the convex ridges are used to prevent the belt body from escaping from the first through hole or the second through hole.

[0010] As a preferred technical solution of the present application, the distance between the first through hole and the second through hole is adapted to the diameter of the pipe on the patient so that the channel formed by the belt passing through the first through hole and then folding back through the second through hole can fix the pipe on the patient.

[0011] As a preferred technical solution of the present application, there are multiple ridges, and the multiple ridges are arranged along the length direction of the belt body.

[0012] As a preferred technical solution of the present application, the thickness and width of the belt body gradually decrease from the convex ridge close to the right end of the belt body to the right end of the belt body.

[0013] As a preferred technical solution of the present application, a fixing device is provided on the belt body, and the fixing device is used to fix the pipe on the patient's body. The fixing device is arranged on the side of the belt body away from the patient's body.

[0014] As a preferred technical solution of the present application, a connecting column is provided between the fixing device and the belt body, and the connecting column is used to support the fixing device so as to separate the fixing device from the belt body.

[0015] As a preferred technical solution of the present application, the fixing device is located in the middle area of ​​the belt body, and the fixing device is an arc-shaped slot, and the arc-shaped slot is used to engage with a pipe on the patient.

[0016] In order to achieve the above-mentioned invention object, the utility model also provides the following technical solutions:

[0017] A retaining needle fixing device adopts the above-mentioned fixing belt, the fixing device is used to fix the retaining needle, the retaining needle comprises a catheter connecting seat, and the size of the arc-shaped card slot is adapted to the size of the catheter connecting seat.

[0018] As a preferred technical solution of the present application, a heparin cap is connected to the catheter connecting seat, and the size of the heparin cap is adapted to the height of the connecting column, so that when the catheter connecting seat is fixed by the arc-shaped slot, the heparin cap is separated from the patient's skin.

[0019] In order to achieve the above-mentioned invention object, the utility model also provides the following technical solutions:

[0020] A catheter fixing device adopts the above-mentioned fixing belt, and the size of the arc-shaped groove is adapted to the size of the catheter.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] 1. In the present application, the fixing belt is placed on the patient's wrist, and then the right side of the belt body is passed around the patient's wrist and then passed through the first through hole on the left side of the belt body, and the convex rib on the right side also passes through the first through hole, so that the belt body forms a ring-shaped sleeve on the patient's wrist, and the setting of the convex rib prevents the belt body from escaping from the first through hole, thus achieving the fixation of the belt body and the patient's wrist; further, the part of the belt body that passes through the first through hole is folded back and passed through the second through hole, and the convex rib also passes through the second through hole, so that a channel is formed between the belt body, the first through hole and the second through hole, and the channel is used for the pipeline on the patient to pass through, and the channel plays a certain role in fixing the pipeline on the patient. In this way, on the one hand, the fixed position of the pipeline on the patient's body is directly avoided from squeezing the patient's skin, reducing the risk of the patient's skin being crushed; on the other hand, because the fixed position of the pipeline on the patient's body is not in direct contact with the patient's skin, a greater force can be used to fix the pipeline on the patient's body, thus greatly improving the firmness of the pipeline on the patient's body being fixed; in the present application, the pipeline on the patient's body can be a catheter, an infusion tube, an indwelling tube, an oxygen tube, etc.;

[0023] 2. The thickness and width of the belt gradually decrease from the convex ridge close to the right end of the belt to the right end of the belt. The above structure is conducive to quickly aligning the right end of the belt with the first through hole on the left side of the belt, so that the belt is quickly formed into a ring and worn on the patient's wrist, which reduces the wearing time of the belt and improves the work efficiency of medical staff. Usually, when putting the belt on the patient, the patient's hand needs to be grasped to limit the patient's hand movement. In particular, for active children, the shorter wearing operation reduces the time that the child's hand movement is restricted, reduces the possibility of the child crying, and is conducive to the treatment of the child.

[0024] 3. The setting of the fixing device increases the number of fixing structures, so that the fixing belt of the present application can fix more pipes. On the other hand, the way of fixing the pipes through the channel formed by the belt body, the first through hole and the second through hole has a certain influence on the fixation of the belt body worn on the patient's wrist. In this way, the device for fixing the pipes is separated from the structure for fixing the belt body on the patient's wrist, which ensures the firmness of the belt body fixed on the patient's wrist and also ensures the firmness of the fixing device for fixing the pipes on the patient's body. In this embodiment, the pipes on the patient's body can be catheters, infusion tubes, indwelling tubes, oxygen tubes, etc.

[0025] 4. The setting of the connecting column allows a certain gap to exist between the fixing device and the belt body. After the fixing device fixes the pipeline on the patient, the pipeline parts that are not fixed on both sides of the fixing device are separated from the patient's skin, reducing the contact between the pipeline parts and the patient's skin, and reducing the risk of damaging the patient's skin due to the friction between the pipeline parts and the patient's skin. At the same time, it provides operating space for medical staff to remove the pipeline from the fixing device, which is convenient for the medical staff to operate and is conducive to improving the work efficiency of the medical staff.

[0037] Example 1: See Figures 1 to 3 As shown,

[0038] The present embodiment provides a fixing belt 1, comprising a belt body 11, wherein a first through hole 12 and a second through hole 13 are provided on the left side of the belt body 11, wherein the first through hole 12 and the second through hole 13 are arranged along the length direction of the belt body 11, and the right side portion of the belt body 11 can pass through the first through hole 12 or the second through hole 13 so that the belt body 11 forms a ring shape, and a convex ridge 14 is provided on the right side of the belt body 11;

[0039] When the right side portion of the belt body 11 passes through the first through hole 12 or the second through hole 13 , the convex ridges 14 are used to prevent the belt body 11 from escaping from the first through hole 12 or the second through hole 13 .

[0040] In this embodiment, the fixing belt 1 is placed on the patient's wrist, and then the right side portion of the belt body 11 is passed around the patient's wrist and then passed through the first through hole 12 on the left side of the belt body 11, and the convex rib 14 on the right side also passes through the first through hole 12, so that the belt body 11 forms a ring and is sleeved on the patient's wrist. The setting of the convex rib 14 prevents the belt body 11 from escaping from the first through hole 12, thus achieving the fixation of the belt body 11 to the patient's wrist; further, the part of the belt body 11 that passes through the first through hole 12 is folded back and passed through the second through hole 13, and the convex rib 14 also passes through the second through hole 13, and the belt body 11, the first through hole 12 and the second through hole 13 are connected. A channel is formed between the two, and the channel is used for the pipelines on the patient to pass through. The channel plays a certain role in fixing the pipelines on the patient. In this way, on the one hand, the squeezing of the patient's skin by the fixed position of the pipeline on the patient is directly avoided, thereby reducing the risk of the patient's skin being crushed; on the other hand, since the fixed position of the pipeline on the patient is not in direct contact with the patient's skin, a greater force can be used to fix the pipeline on the patient, thereby greatly improving the firmness of the pipeline on the patient. In this embodiment, the pipeline on the patient can be a catheter, an infusion tube, an indwelling tube, an oxygen tube, etc.

[0041] As a preferred embodiment, on the basis of the above method, further, the distance between the first through hole 12 and the second through hole 13 is adapted to the diameter of the pipe on the patient so that the belt body 11 passes through the first through hole 12 and then folds back to pass through the second through hole 13 to form a channel that can fix the pipe on the patient.

[0042] The above structure increases the strength for fixing the pipes on the patient, and greatly improves the firmness with which the pipes on the patient are fixed.

[0043] As a preferred implementation, based on the above-mentioned implementation, further, the number of the convex ridges 14 is multiple, and the multiple convex ridges 14 are arranged along the length direction of the belt body 11 .

[0044] The arrangement of multiple ridges 14 facilitates adjustment of the size of the ring formed by the belt body 11. On the one hand, it is convenient for patients with different wrist sizes to wear it. On the other hand, it is convenient for the same patient to adjust the tightness of the belt body 11, thereby improving the flexibility of the use of the fixing belt 1 of the present application.

[0045] As a preferred embodiment, based on the above-mentioned manner, further, from the convex ridge 14 close to the right end of the belt body 11 to the right end of the belt body 11, the thickness and width of the belt body 11 gradually decrease.

[0046] The above structure is adopted, which is conducive to quickly aligning the right end of the belt body 11 with the first through hole 12 on the left side of the belt body 11, so that the belt body 11 is quickly formed into a ring and worn on the patient's wrist, reducing the wearing time of the belt body 11 and improving the work efficiency of medical staff; usually when wearing the belt body 11 for the patient, it is necessary to grasp the patient's hand to limit the patient's hand movement. In particular, for active children, the shorter wearing operation reduces the time that the child's hand movement is restricted, reduces the possibility of the child crying, and is conducive to the treatment of the child.

[0047] Example 2: See Figure 2 and Figure 3 As shown,

[0048] On the basis of the technical solution of the first embodiment, further, a fixing device 2 is provided on the belt body 11, and the fixing device 2 is used to fix the pipe on the patient's body. The fixing device 2 is arranged on the side of the belt body 11 away from the patient's body.

[0049] On the one hand, the provision of the fixing device 2 increases the number of fixing structures, so that the fixing belt 1 of the present application can fix more pipes. On the other hand, the way of fixing the pipes through the channel formed by the belt body 11, the first through hole 12 and the second through hole 13 has a certain influence on the fixation of the belt body 11 worn on the patient's wrist. In this way, the device for fixing the pipes is separated from the structure for fixing the belt body 11 on the patient's wrist, which ensures the firmness of the belt body 11 fixed to the patient's wrist, and also ensures the firmness of the fixing device 2 to the pipes on the patient. In this embodiment, the pipes on the patient can be catheters, infusion tubes, indwelling tubes, oxygen tubes, etc.

[0050] As a preferred embodiment, on the basis of the above-mentioned manner, further, a connecting column 22 is provided between the fixing device 2 and the belt body, and the connecting column 22 is used to support the fixing device 2 so that the fixing device 2 is separated from the belt body 11.

[0051] The setting of the connecting column 22 allows a certain gap to be provided between the fixing device 2 and the belt body 11. After the fixing device 2 fixes the pipe on the patient's body, the unfixed pipe parts on both sides of the fixing device 2 are separated from the patient's skin, thereby reducing the contact between this part of the pipe and the patient's skin, and reducing the risk of damaging the patient's skin due to friction between this part of the pipe and the patient's skin. At the same time, it provides operating space for medical staff to remove the pipe from the fixing device 2, facilitates the operation of medical staff, and improves the work efficiency of medical staff.

[0052] As a preferred embodiment, based on the above-mentioned manner, further, the fixing device 2 is located in the middle area of ​​the belt body 11, and the fixing device 2 is an arc-shaped slot 21, and the arc-shaped slot 21 is used to embed the pipe on the patient.

[0053] The fixing device 2 is arranged in the middle area of ​​the belt body 11. When the belt body 11 is formed into a ring and worn on the patient's wrist, the fixing device 2 is located on the side of the patient's wrist close to the back of the hand. The clamping position of the convex ridge 14 and the first through hole 12 or the second through hole 13 is located on the side of the patient's wrist close to the palm. In this way, the mutual influence between fixing the pipe on the patient and fixing the belt body 1 on the patient's wrist is reduced. At the same time, the fixing device 2 located on the side of the patient's wrist close to the back of the hand facilitates the fixing of the pipe on the back of the patient's hand. The arc-shaped clamping groove 21 is adopted, which has a simple structure and is easy to operate, thereby improving the work efficiency of medical staff and reducing the discomfort of patients.

[0054] Example 3: See Figure 4 As shown,

[0055] A device for fixing an indwelling needle adopts the above-mentioned fixing belt 1. The fixing device 2 is used to fix the indwelling needle 3. The indwelling needle 3 includes a catheter connecting seat 31. The size of the arc-shaped slot 21 is adapted to the size of the catheter connecting seat 31.

[0056] The needle tube of the indwelling needle 3 is fixed on the back of the patient's hand by means of an adhesive tape, and then the catheter connecting seat 31 is clamped in the arc-shaped clamping groove 21. In this way, the risk of displacement of the catheter connecting seat 31 causing displacement of the needle tube of the indwelling needle 3 is reduced, which is beneficial to the fixation of the indwelling needle 3. At the same time, the contact between the catheter connecting seat 31 and the patient's skin is reduced, and the pressure of the catheter connecting seat 31 on the patient's skin is reduced, which is beneficial to the treatment of the patient.

[0057] As a preferred embodiment, on the basis of the above method, further, a heparin cap 32 is connected to the catheter connecting seat 31, and the size of the heparin cap 32 is adapted to the height of the connecting column 22, so that when the catheter connecting seat 31 is fixed by the arc-shaped slot 21, the heparin cap 32 is separated from the patient's skin.

[0058] Usually, the diameter of the heparin cap 31 of the indwelling needle 3 is larger than the diameter of the catheter connecting seat 31. The above structure can fix the catheter connecting seat 31 while avoiding the heparin cap 32 from pressing the patient's skin, which is beneficial to the treatment of the patient.

[0059] Example 4: See Figure 5 As shown,

[0060] A catheter fixing device is provided. The catheter fixing device adopts the fixing belt 1 mentioned above. The size of the arc-shaped slot 21 is adapted to the size of the catheter 4 .

[0061] The catheter fixing device using the fixing belt 1 can fix the catheter 4 more stably and flexibly, reduce the workload of medical staff, reduce harm to patients, and facilitate the treatment of patients.

[0062] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
