Description

Technical Field

[0001] The utility model belongs to the technical field of PICC catheter fixing, in particular to a PICC catheter fixing device. Background Art

[0002] PICC catheter is a central venous catheter inserted through a peripheral vein, mainly used for patients who need long-term intravenous infusion, chemotherapy or blood product transfusion. This catheter can be placed in the central vein for a long time, thus reducing the pain caused by each puncture and reducing damage to the blood vessels.

[0003] In order to prevent the PICC catheter from swinging or being pulled out and causing damage to the blood vessels, the PICC catheter needs to be fixed. The conventional means is to use a fixing patch to stick it on the skin for fixing. However, the fixing patch will fail due to the sweat secreted by the skin, so the fixing effect of the fixing patch is not good. In the prior art, a fixing structure is worn on the arm, and the PICC catheter is clamped and fixed by the fixing structure. For example, the patent with publication number CN219539080U discloses a PICC catheter fixing clamp, which includes a main body component and a heating component. The main body component includes an elastic buckle, and a clamping block that is movably connected to the front and rear ends of the top of the elastic buckle through a first spring; the heating component includes a mounting plate arranged on one side of the elastic buckle, a ring slidably connected to both sides of the rear end of the mounting plate, and a graphene heating plate. Since the clamping block is protrudingly arranged on the top of the elastic buckle, it is easy to hook on the suture line of clothes or sheets, resulting in the risk of the entire fixing clamp slipping off, thereby affecting the fixing effect of the PICC catheter. Utility Model Content

[0025] Combine the following Figure 1-Figure 5 The utility model is described in detail.

[0026] Example

[0027] A PICC catheter holder comprises a box body 1 with an opening on the upper part, a cover plate 4 for closing the opening movably provided on the box body 1, limiting slide grooves 9 for placing a PICC catheter 10 are vertically provided on both sides of the box body 1, and a clamping mechanism 8 for clamping and fixing the PICC catheter 10 is provided in the box body 1.

[0028] The clamping mechanism 8 for fixing the PICC catheter 10 is arranged in the box body 1 to reduce the probability of the clamping mechanism 8 hooking the suture, and the cover plate 4 then closes the opening of the box body 1 to further prevent the suture from extending into the box body 1 and hooking the clamping mechanism 8. When fixing, the cover plate 4 is opened and the PICC catheter 10 is inserted into the limiting slide groove 9, and then the clamping mechanism 8 clamps and fixes the PICC catheter 10, and finally the cover plate 4 is closed.

[0029] The cover plate 4 is hinged to the box body 1, and an arc-shaped clamping block 7 is provided on the inner wall of the box body 1. An elastic fixing block 5 is provided on the inner side of the cover plate 4, and a clamping groove 6 is provided on the side of the elastic fixing block 5 close to the arc-shaped clamping block 7. After the cover plate 4 closes the box body 1, the clamping groove 6 on the elastic fixing block 5 is engaged with the arc-shaped clamping block 7, thereby fixing the cover plate 4. When the cover plate 4 needs to be opened, it is only necessary to lift the cover plate 4 upward from the limiting sliding groove 9, and the elastic fixing block 5 is deformed due to the elastic effect, so that the clamping groove 6 is separated from the arc-shaped clamping block 7 to release the fixation of the cover plate 4.

[0030] The clamping mechanism 8 includes two fixing seats 801 fixedly arranged in the box body 1, a guiding square groove 806 penetrating the fixing seat 801 is horizontally arranged in the fixing seat 801, a square rod 807 is movably arranged in the guiding square groove 806, one end of the square rod 807 is connected to an arc-shaped clamping plate 805, a strip groove 802 penetrating the guiding square groove 806 is vertically arranged in the fixing seat 801, a wedge-shaped plug rod 808 is vertically movably arranged in the strip groove 802 and the wedge-shaped plug rod 808 movably penetrates the square rod 807, a ratchet 803 cooperating with the wedge-shaped plug rod 808 is arranged at the bottom of the strip groove 802, a tension spring 809 is sleeved on the wedge-shaped plug rod 808, and the two ends of the tension spring 809 are fixedly connected to the square rod 807 and the top of the wedge-shaped plug rod 808.

[0031] The wedge-shaped rod 808 cooperates with the ratchet 803 so that the arc-shaped splint 805 can only move in the direction close to the PICC catheter 10. Under the action of the tension spring 809, the wedge-shaped rod 808 always keeps cooperating with the ratchet 803. When the arc-shaped splint 805 needs to be moved away from the PICC catheter 10, it is only necessary to pull up the wedge-shaped rod 808. The fixing operation of the entire clamping mechanism 8 is simple and convenient. It only requires pressing the two square rods 807 at the same time. Compared with the method of driving the arc-shaped splint 805 to move by a screw, the clamping mechanism 8 of the present application can achieve rapid clamping and fixing.

[0032] An anti-skid pad 804 is provided on the inner side of the arc-shaped splint 805. The anti-skid pad 804 can increase the friction between the arc-shaped splint 805 and the PICC catheter 10, thereby preventing the PICC catheter 10 from axial displacement.

[0033] A heating device 11 clamped on the PICC catheter 10 is arranged in the box body 1, and the heating device 11 includes two hinged arc-shaped clamping arms 1101 and a torsion spring is arranged at the hinge, and a heating plate 1102 is arranged on the inner side of the arc-shaped clamping arms 1101. The heating device 11 is clamped on the PICC catheter 10 by the arc-shaped clamping arms 1101, so that the heating plate 1102 is attached to the surface of the PICC catheter 10, and the liquid medicine transported by the PICC catheter 10 can be heated to avoid the low-temperature liquid medicine causing discomfort to the patient. The wire connected to the heating plate 1102 can be stored in the box body 1, and the wire is taken out and connected to an external power supply when it is needed. The heating device 11 is installed on the PICC catheter 10 in a clamping manner, which is convenient for the heating plate 1102 to be quickly replaced after it is damaged.

[0034] The bottom of the box body 1 is provided with an arc-shaped silicone pad 2. The arc-shaped silicone pad 2 can be closely attached to the patient's arm to increase friction and ensure that the entire fixator does not move.

[0035] Both sides of the box body 1 are connected with straps 3, on which Velcro is arranged, and the straps 3 fix the fixator on the patient's arm. The Velcro can conveniently adjust the binding size of the straps 3 and facilitate the removal of the fixator.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
