Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to an anti-bending device for an infusion catheter. Background Art

[0002] In medicine, CVC usually stands for central venous catheter. A specific analysis is as follows: a central venous catheter can generally be inserted into the body through the neck, subclavian, or femoral vein. A central venous catheter enters the heart cavity through a puncture of the vein, passing through the superior vena cava or inferior vena cava. This facilitates the infusion of nutrients, intravenous injection of drugs, and monitoring of central venous pressure. Central venous catheters are widely used in medical settings such as surgery, emergency care, intensive care, cancer chemotherapy, and long-term peritoneal dialysis. Their advantage is that they can provide patients with large-volume infusions, immunoglobulins, and nutritional support while reducing the need for percutaneous venipuncture and central venous puncture, thereby reducing the risk of complications and infection.

[0003] When a central venous catheter is inserted into the human body, there are certain risks, such as possible damage to the vein, pneumothorax, hematoma at the puncture site, etc. During the use of the central venous catheter, attention should be paid to local care; if you feel unwell, you should seek medical attention in time. When the central venous catheter is in use, after the midline catheter is connected to the infusion line, the infusion port is easily bent during the infusion process, which will cause the patient's infusion to be blocked during treatment, causing inconvenience to the patient's rehabilitation treatment. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present invention is to provide an infusion catheter anti-bending device, which effectively solves the problem that the patient's central venous catheter is prone to bending when receiving infusion.

[0005] The technical solution is that the utility model includes a sliding rod in the left and right directions, and the left and right ends of the sliding rod are respectively slidably connected to a sliding cylinder, and a plurality of limit grooves evenly distributed along the left and right directions and connected to the inner side of the sliding cylinder are opened on the lower side wall of the sliding cylinder. The left and right ends of the sliding rod are respectively fixed with an inverted L-shaped limit rod made of elastic material, and the limit rod can be inserted into the limit groove. The upper ends of the two sliding cylinders are respectively fixed with an arc-shaped positioning sleeve with an opening facing upward, and the upper ends of the two positioning sleeves are respectively hinged with an arc-shaped pressing sleeve, and the cross-section of the pressing sleeve and the positioning sleeve can form a circle.

[0006] The utility model has an ingenious structure and is easy to use. It is convenient for medical staff to clamp and position the infusion connection when the patient's central venous catheter is infused, so as to prevent the connection from bending and affecting the patient's rehabilitation treatment. At the same time, when in use, the slide cylinder can be moved relative to the slide rod by moving the slide cylinder, thereby increasing or decreasing the fixed length, so that medical staff can change different connection lengths according to the connection conditions of the patient's pipeline when using it. Moreover, the device does not need to be placed on the bed or the patient's clothes when in use. The overall size is small, which avoids inconvenience to the patient and improves the patient's comfort. This device has a simple structure, is easy to operate, has a novel concept and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.

[0013] Depend on Figures 1 to 5 It is given, including a slide rod 1 in the left and right directions, and the left and right ends of the slide rod 1 are respectively slidably connected to a slide cylinder 2, and a plurality of limit grooves 3 are opened on the lower side wall of the slide cylinder 2, which are evenly distributed along the left and right directions and connected to the inner side of the slide cylinder 2. The left and right ends of the slide rod 1 are respectively fixed with an inverted L-shaped limit rod 4 made of elastic material, and the limit rod 4 can be inserted into the limit groove 3. The upper ends of the two slide cylinders 2 are respectively fixed with an arc-shaped positioning sleeve 5 with an opening facing upward, and the upper ends of the two positioning sleeves 5 are respectively hinged with an arc-shaped pressing sleeve 6, and the cross-section of the pressing sleeve 6 and the positioning sleeve 5 can form a circle.

[0014] In order to facilitate the swing of the limiting rod 4 , a clearance groove 7 is respectively opened at the left and right ends of the sliding rod 1 , and the limiting rod 4 is located in the clearance groove 7 .

[0015] In order to facilitate the swing of the limit rod 4, a movable plate 8 that can move up and down is provided on the lower side of the slide 2. A plurality of push blocks 9 that correspond one to one with the limit slots 3 and can be inserted into the limit slots 3 are fixed on the upper end of the movable plate 8.

[0016] In order to facilitate the sliding of the movable plate 8, inverted T-shaped positioning blocks 10 are fixed on the left and right sides of the lower end of the slide 2 respectively. The movable plate 8 is slidably connected to the positioning blocks 10 and can contact the stepped surfaces of the positioning blocks 10.

[0017] In order to facilitate clamping of the pipe end, elastic pressure pads 11 are respectively provided in the positioning sleeve 5 and the pressing sleeve 6.

[0018] In order to facilitate the connection between the pressing sleeve 6 and the positioning sleeve 5, a card slot 12 with an upward opening and a rear end connected to the outside is opened on the rear side of the positioning sleeve 5, and an elastic card buckle 13 that can be inserted into the card slot 12 is fixed on the lower side of the rear end of the pressing sleeve 6.

[0019] When the present invention is in use, the medical staff presses the two movable plates 8 upwards, and the movable plates 8 drive the multiple push rods to be inserted into the limit slots 3, and squeeze the limit rods 4, so that the limit rods 4 swing upwards to the clearance slots 7, and at the same time the limit rods 4 are removed from the limit slots 3. At this time, the medical staff can position the length of the pipeline as needed, move the slide cylinder 2 left and right, and move the slide cylinder 2 relative to the slide rod 1 to change the distance between the two slide cylinders 2, thereby adapting to the length of the pipeline;

[0020] After the slide 2 has finished moving, the movable plate 8 is released. At this time, under the action of gravity and the elasticity of the limit rod 4, the movable plate 8 moves downward, and the limit rod 4 is reinserted into the limit groove 3, limiting the relative sliding between the slide 2 and the slide rod 1;

[0021] At this time, place the two ends of the pipeline connection in the positioning sleeve 5, and swing the pressing sleeve 6 at the same time to fix the pipeline through the elastic pressure pad 11. At the same time, clamp and fix the pipeline connection port on the other side, and insert the elastic buckle 13 into the card slot 12 to complete the connection between the pressing sleeve 6 and the positioning sleeve 5, and position the pipeline port and its connection.

[0022] The utility model has an ingenious structure and is easy to use. Through the positioning sleeve, the slide cylinder, the slide rod and the pressure sleeve, medical staff can clamp and position the infusion connection when the patient's central venous catheter is infused, so as to prevent the connection from bending and affecting the patient's rehabilitation treatment. At the same time, when in use, the slide cylinder can be moved relative to the slide rod to increase or decrease the fixed length, so that medical staff can change different connection lengths according to the connection conditions of the patient's pipeline when using it. Moreover, the device does not need to be placed on the bed or the patient's clothes when in use. The overall size is small, which avoids inconvenience to the patient and improves the patient's comfort. This device has a simple structure, is easy to operate, has a novel concept and is highly practical.
