Description

Technical Field

[0001] The utility model relates to the field of PICC catheter limiting equipment, in particular to a clinical PICC catheter limiter for tumor nursing. Background Art

[0002] PICC catheters are typically inserted through a peripheral vein puncture in the upper limb, such as the basilic vein, median cubital vein, or cephalic vein, with the catheter tip positioned in the superior or inferior vena cava. They provide patients with a safe and effective method for intravenous infusion. While using a PICC catheter, regular maintenance is required, including flushing and dressing changes. Avoid strenuous exercise to prevent catheter displacement or dislocation, and observe the skin surrounding the catheter for any abnormalities.

[0003] The existing PICC catheter limiter clamps the joint of the PICC catheter inside by installing a box cover and a box body on a breathable adhesive tape. When medical staff need to replace the limiter or clean the skin tissue in the adhesive area of the limiter adhesive layer, the box cover is stuck on the box body for a long time, and medical staff need to spend a lot of effort to remove the box cover from the box body. Medical staff are likely to press the patient's intubation site with their hands, causing increased pain for patients. Therefore, we propose a clinical PICC catheter limiter for tumor nursing. Utility Model Content

[0004] The main purpose of the utility model is to provide a clinical PICC catheter limiter for tumor nursing, which can effectively solve the problem in the background technology that when medical personnel need to replace the limiter or clean the skin tissue in the adhesive area of the limiter adhesive layer, the box cover and the box body are too tight, which makes it easy for the medical personnel's hands to press on the patient's intubation site, thereby increasing the patient's pain.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A PICC catheter limiter for clinical tumor nursing comprises a breathable layer, a card-jointed box body is installed in the middle of the upper end of the breathable layer, two groups of symmetrically distributed positioning columns are movably installed in the inner cavity of the card-jointed box body, locking box covers are movably installed on the left and right sides of the upper end of the card-jointed box body, two groups of symmetrically distributed locking mechanisms are installed on the front and rear ends of the card-jointed box body, the locking mechanism comprises an insert block, and the insert block is equipped with a matching claw for clamping the locking box cover, and an adhesive layer is adhered to the lower end of the breathable layer.

[0007] Preferably, a supporting plate is fixedly connected to the inner cavity side wall of the clamping box body. A limiting sliding groove is formed in the middle of the upper end of the supporting plate. The positioning column is slidably installed in the limiting sliding groove. The limiting sliding groove allows the two positioning columns to slide therein, facilitating the adjustment of the distance between the two positioning columns. When the catheter joint part needs to be sleeved on the positioning column, the distance between the two appropriate positioning columns can be adjusted according to the width of the catheter joint part, facilitating the medical staff to quickly fix the catheter joint.

[0008] Preferably, a placing round hole is formed in the middle of the upper end of the positioning column. A ejector rod is slidably connected in the placing round hole. The bottom of the ejector rod is fixedly connected with a first spring. When the medical staff needs to replace the limiter or clean the skin tissue in the sticking area of the limiter sticking layer, the first spring can give the ejector rod a thrust to bounce open the locking box cover, facilitating the medical staff to take out the catheter joint part stuck between the clamping box body and the locking box cover, and further facilitating the medical staff to replace the limiter and clean the skin tissue in the sticking area of the limiter sticking layer.

[0009] Preferably, two symmetrically distributed clamping claws are fixedly installed on the bottom wall of the inner cavity of the locking box cover. When the locking box cover is closed on the clamping box body, the clamping claws can be clamped together with the locking mechanism to lock the locking box cover and the clamping box body together, thereby fixing the catheter joint part in the clamping box body.

[0010] Preferably, the locking mechanism includes an insertion block, a mating claw and a second spring. A mating claw is fixedly connected to one side of the upper end of the insertion block close to the positioning column. A second spring is fixedly connected to one end of the insertion block close to the positioning column. The lower part of the insertion block is slidably connected to the bottom wall of the inner cavity of the clamping box body. The second spring can give the insertion block an outward elastic force. When the mating claw and the clamping claw are clamped together, the mating claw installed on the insertion block can be kept in a clamped state to close the locking box cover tightly on the upper part of the clamping box body.

[0011] Preferably, one end of the insertion block far from the positioning column penetrates through the side wall of the clamping box body and is fixedly connected with a pressing head. The pressing head facilitates the medical staff to, when needing to replace the limiter, press the pressing head to make the mating claw move inwards, so that the clamping claw is unhooked and the locking box cover is opened from the clamping box body, avoiding the medical staff using too much force to open the locking box cover and pulling the catheter, causing pain to the patient.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By setting positioning posts and arranging a first spring inside the positioning posts, when medical staff need to replace the limiter or clean the skin tissue in the pasted area of the limiter's adhesive layer, the first spring can give a push to the ejector rod, bounce open the locking box cover, facilitating the medical staff to take out the catheter joint part stuck between the clamping box body and the locking box cover, and thus facilitating the medical staff to replace the limiter and clean the skin tissue in the pasted area of the limiter's adhesive layer.

[0014] 2. By setting a locking mechanism and clamping claws, when medical staff need to replace the limiter, pressing the pressing head makes the cooperating claws move inward, so that the clamping claws are disengaged, and the locking box cover is opened from the clamping box body, avoiding the medical staff exerting too much force when opening the locking box cover and pulling the catheter, causing pain to the patient.

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment

[0022] Please refer to Figure 1 - Figure 4, this embodiment provides a technical solution: a PICC catheter limiter for clinical tumor care, including a breathable layer 1. In the middle of the upper end of the breathable layer 1, a clamping box body 2 is installed. Inside the cavity of the clamping box body 2, two groups of symmetrically distributed positioning columns 3 are movably installed. On the left and right sides of the upper end of the clamping box body 2, two groups of locking box covers 4 are movably installed. On the front and rear ends of the clamping box body 2, two groups of symmetrically distributed locking mechanisms 5 are installed. The locking mechanism 5 includes an insertion block 51, and on the insertion block 51, there is a mating claw 52 for clamping the locking box cover 4. A paste layer 6 is attached to the lower end of the breathable layer 1.

[0023] On the side wall of the inner cavity of the clamping box body 2, a supporting plate 21 is fixedly connected. In the middle of the upper end of the supporting plate 21, a limiting sliding groove 22 is opened. The positioning column 3 is slidably installed in the limiting sliding groove 22. The limiting sliding groove 22 allows the two groups of positioning columns 3 to slide therein, facilitating the adjustment of the distance between the two groups of positioning columns 3. When the catheter joint part needs to be sleeved on the positioning column 3, the distance between the two groups of positioning columns 3 can be adjusted according to the width of the catheter joint part, facilitating medical staff to quickly fix the catheter joint.

[0024] In the middle of the upper end of the positioning column 3, a placement round hole 31 is opened. In the placement round hole 31, a top rod 32 is slidably connected. The bottom of the top rod 32 is fixedly connected with a first spring 33. When medical staff needs to replace the limiter or clean the skin tissue in the pasted area of the limiter paste layer, the first spring 33 can give the top rod 32 a thrust to pop open the locking box cover 4, facilitating medical staff to take out the catheter joint part stuck between the clamping box body 2 and the locking box cover 4, and then facilitating medical staff to replace the limiter and clean the skin tissue in the pasted area of the limiter paste layer.

[0025] On the bottom wall of the inner cavity of the locking box cover 4, two groups of symmetrically distributed clamping claws 41 are fixedly installed. When the locking box cover 4 is closed on the clamping box body 2, the clamping claws 41 can be clamped together with the locking mechanism 5 to lock the locking box cover 4 and the clamping box body 2 together, thereby fixing the catheter joint part in the clamping box body 2.

[0026] The locking mechanism 5 includes an insertion block 51, a mating claw 52, and a second spring 53. On the side of the upper end of the insertion block 51 close to the positioning column 3, mating claws 52 are fixedly connected. At one end of the insertion block 51 close to the positioning column 3, second springs 53 are fixedly connected. The lower part of the insertion block 51 is slidably connected with the bottom wall of the inner cavity of the clamping box body 2. The second spring 53 can give the insertion block 51 an outward elastic force. When the mating claw 52 and the clamping claw 41 are clamped together with each other, the mating claw 52 installed on the insertion block 51 can be kept in a clamped state to close the locking box cover 4 tightly on the upper part of the clamping box body 2.

[0027] One end of the insert block 51 away from the positioning post 3 penetrates through the side wall of the clamping box body 2 and is fixedly connected with a pressing head 511. The pressing head 511 facilitates medical staff to press the pressing head 511 when the stopper needs to be replaced, so that the cooperating claw 52 moves inward, thereby disengaging the clamping claw 41 and opening the locking box cover 4 from the clamping box body 2, avoiding excessive force used by medical staff to open the locking box cover 4 and pulling the catheter, which causes pain to the patient.

[0028] Working principle:

[0029] It should be noted that the present utility model is a tumor care clinical PICC catheter stopper. When in use, medical staff disinfect the area to be pasted, open the locking box cover 4 by pressing the pressing head 511, then tear off the sticker on the adhesive layer 6, and paste the stopper at the position where the patient needs to fix the catheter. The limit sliding groove 22 allows the two positioning posts 3 to slide therein, facilitating the adjustment of the distance between the two positioning posts 3. When the catheter joint needs to be sleeved on the positioning post 3, the distance between the two appropriate positioning posts 3 can be adjusted according to the width of the catheter joint, facilitating medical staff to quickly fix the catheter joint. When medical staff need to replace the stopper or clean the skin tissue in the pasting area of the adhesive layer of the stopper, by pressing the pressing head 511, the cooperating claw 52 moves inward, thereby disengaging the clamping claw 41 and opening the locking box cover 4 from the clamping box body 2. The first spring 33 can give a thrust to the ejector rod 32 to bounce open the locking box cover 4, facilitating medical staff to take out the catheter joint part stuck between the clamping box body 2 and the locking box cover 4, and further facilitating medical staff to replace the stopper and clean the skin tissue in the pasting area of the adhesive layer of the stopper.
