Description

Technical Field

[0001] The utility model relates to the technical field of catheter placement and fixation, in particular to a fixer for tightening the skin of a PICC catheter. Background Art

[0002] PICC catheters are generally fixed with medical tape and bandages. PICC is a peripherally inserted central venous catheter. Peripherally inserted central venous catheters are a new technology that has emerged in recent years. When the exposed PICC catheter is bent into an S shape for fixation, the nursing staff needs to bend the exposed PICC catheter into an S shape with one hand and also need to keep it fixed. For this, some technical solutions have emerged. For example, a PICC catheter fixer recorded in publication number CN219001438U includes a lower fixing plate, a rubber cushion is fixedly connected to the lower end of the lower fixing plate, and threaded columns are fixedly connected at the four corners of the upper end of the lower fixing plate, and an upper fixing plate is slidably sleeved on the outer walls of the four threaded columns;

[0003] The above structure can fix the exposed PICC catheter bent into an S shape between the lower S-shaped groove and the upper S-shaped groove by using an upper fixing plate, an upper S-shaped groove, four threaded columns and four fastening rings. However, for the elderly, due to their loose skin, the skin at the contact point between the fixator and the skin and around the strap is prone to loosening during operation, which can cause skin itching and pain, reducing the patient's comfort. Utility Model Content

[0004] The utility model aims to provide a PICC catheterization skin tightening fixator to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A fixer for tightening the skin for PICC catheter placement comprises a hard upper shell, the lower surface of the hard upper shell is fixedly connected to a flexible lower shell, the front surface of the hard upper shell is fixedly connected to a No. 1 slide bar, the outer surface of the No. 1 slide bar is slidably connected to a No. 1 slide seat, the upper surface of the hard upper shell is embedded with a cover body, the upper surface of the hard upper shell is embedded with a slide bar, the lower surface of the flexible lower shell is bonded with release paper, the lower surface of the release paper is fixedly connected to a connecting strip, the upper surface of the hard upper shell is wrapped with a No. 1 bandage, the upper surface of the hard upper shell is wrapped with a No. 2 bandage at a position away from the No. 1 bandage, and the outer surfaces of the No. 1 bandage and the No. 2 bandage are both nested and connected with a limiting seat.

[0024] Specifically, when in use, the flexible lower shell 202 can be deformed under force, so that the fixator and the skin are in closer contact. The hard upper shell 2 and the flexible lower shell 202 are fixed at the catheter placement position through the cooperation of the No. 1 strap 7 and the No. 2 strap 706. Then, the connecting strip 601 is pulled to tear off the release paper 6, so that the flexible lower shell 202 is adhered to the catheter placement position. The PICC catheter body 1 is adhered to the upper surface of the hard upper shell 2 with medical tape to complete the fixation of the PICC catheter body 1.

[0025] Embodiment 1

[0026] like Figure 1 , 2 As shown in Figure 4, in this embodiment, ventilation holes 203 are provided on the upper surfaces of the hard upper shell 2 and the flexible lower shell 202, an embedding groove 204 is provided on the upper surface of the hard upper shell 2, a connecting frame 205 is fixedly connected to the front surface of the hard upper shell 2, an S-shaped groove 207 is provided on the upper surface of the hard upper shell 2, an adhesive layer 208 is sprayed on the lower surface of the hard upper shell 2 near the edge, a through groove 201 is provided on the upper surface of the hard upper shell 2, the No. 1 strap 7 and the No. 2 strap 706 are wrapped around the hard upper shell 2 through the through groove 201, a sliding groove 206 is provided on the upper surface of the hard upper shell 2, the sliding rod 5 is slidably connected to the sliding groove 206, and the outer surface of the sliding rod 5 is located below the hard upper shell 2 and is embedded with a circular insertion rod.

[0027] In this embodiment, since the fixator is used to fix the PICC catheter body 1 on the skin, the flexible tube portion located in the vein Figure 1 Not shown, the hard upper shell 2 strengthens the strength of the fastener, the air holes 203 increase the breathability of the fastener to prevent bedsores, the adhesive layer 208 is used to bond the fastener to the skin, and the insertion rod limits the sliding rod 5 to prevent the sliding rod 5 from being forced to withdraw from the slide groove 206.

[0028] like Figure 3 As shown, in this embodiment, a limiting groove 301 is provided on the outer surface of the No. 1 slide bar 3, a No. 1 spring piece 303 is movably connected to the outer surface of the No. 1 slide seat 302, two No. 2 slide bars 702 are fixedly connected to the upper surface of the limiting seat 701, the outer surface of the No. 2 slide bar 702 is slidably connected to the No. 2 slide seat 703, the outer surface of the No. 2 slide seat 703 is movably connected to the No. 2 spring piece 704, the No. 1 slide seat 302 and the No. 2 slide seat 703 have the same structure, and the outer surfaces of the No. 1 strap 7 and the No. 2 strap 706 are fixedly connected with Velcro 705.

[0029] In specific implementation, Velcro 705 is sewn on the lower surface of the end of No. 1 strap 7 and the upper surface of the end of No. 2 strap 706. Through the mutual adhesion of Velcro 705, No. 1 strap 7 and No. 2 strap 706 simply fix the hard upper shell 2, and further fix the flexible lower shell 202. At this time, the release paper 6 has not been torn off. Therefore, the No. 1 spring piece 303 is pushed upward, and the No. 1 slide seat 302 is slid along the No. 1 slide rod 3. The lower surface of the No. 1 slide seat 302 contacts the patient's skin, loosening After the hand, the No. 1 spring piece 303 contacts the limiting groove 301 to fix the No. 1 slide 302. The same is true for the No. 2 slide 703. The difference is that the limiting seat 701 can move along the No. 1 strap 7 or the No. 2 strap 706. Therefore, the No. 1 slide 302 cooperates with the No. 2 slide 703 to apply an outward force to the skin around the hard upper shell 2, so that the patient's skin is tightened. The tightened skin can reduce the skin itching and pain caused by skin sagging, thereby improving the patient's comfort.
