Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a PICC maintenance auxiliary bracket. Background Art
[0002] PICC is a peripherally inserted central venous catheter, which is inserted into a peripheral vein with the catheter tip located at the entrance of the right atrium in the lower 1 / 3 of the superior vena cava. It is used to provide patients with medium- and long-term intravenous infusion therapy.
[0003] After searching, Chinese patent CN219423527U was found and announced a PICC catheter placement and dressing change auxiliary frame. The fixing buckle installed on the upper end of the protective shell is fixed by the fixing groove opened on the bandage. The first slide groove opened on the upper end of the protective shell adjusts its position by the telescopic spring and the film plate installed inside. A Silo buckle is installed on the fixing block to fix the catheter. A layer of film is attached to the catheter through the film plate on the side to achieve double insurance, avoiding the catheter from falling off when the Silo buckle fixed by the fixing pad is not completely disassembled due to the dissolution of the adhesive. By replacing the fixing groove on the bandage and the fixing buckle installed on the protective shell The fixed buckle can be disassembled separately, avoiding the situation that the Sling buckle that can continue to be used can continue to be used through the strap. The damaged strap or protective shell can be cleaned and replaced in time. It can be seen that this patent realizes the double insurance fixation of the PICC catheter and the cleaning and replacement of the strap and protective shell. When the PICC catheter is maintained, the catheter uses the patient's own arm as a support point through the strap and the bracket, which can effectively prevent the patient from slipping due to uncontrollable factors (confused consciousness, uncooperative children, etc.) during the maintenance process. At the same time, by adjusting the height of the bracket, the smooth progress of the maintenance can be guaranteed. For this purpose, a PICC maintenance auxiliary bracket is proposed.

The side wall of the support tube 2 is provided with an opening 4 that is connected to the inner cavity of the support tube 2. A fixing tube 5 is fixedly installed between the opposite sides of the front side wall and the rear side wall of the support tube 2.
[0024] Among them, there is a receiving groove 8 in the cuff 1, and a through hole 9 connected to the receiving groove 8 is opened on the surface wall of the cuff 1. A base 10 is installed in the receiving groove 8 and the through hole 9. The material of the base 10 is plastic, so that the base 10 has toughness. The two ends of the base 10 can be bent, and then the base 10 can be inserted into the receiving groove 8 through the through hole 9 for placement.
[0025] See also Figure 3-4 A connecting component 11 is arranged between the supporting tube 2 and the opposite side of the base 10, and the connecting component 11 includes a mother buckle 111 and a sub-buckle 112. The mother buckle 111 is installed on the top of the base 10, and the sub-buckle 112 is installed on the tail of the supporting tube 2. The mother buckle 111 is adapted to the sub-buckle 112. A friction layer is arranged between the opposite sides of the mother buckle 111 and the sub-buckle 112 to improve the stability of the connection between the mother buckle 111 and the sub-buckle 112. The mother buckle 111 and the sub-buckle 112 are plugged into each other. The sub-buckle 112 is inserted into the mother buckle 111 from left to right to connect the cuff 1 and the supporting tube 2. The sub-buckle 112 is removed from the mother buckle 111 from right to left to disassemble the cuff 1 and the supporting tube 2, which facilitates the assembly and disassembly of the cuff 1 and the supporting tube 2.
[0026] See also Figure 2 and Figure 5 An adjustment component 6 is provided on the supporting cylinder 2 and the fixed cylinder 5. The adjustment component 6 includes a movable shaft 61, a lightweight rod frame 62, a gear 63, a support spring 64 and a positioning block 65. The movable shaft 61 is rotatably connected between the front side wall and the opposite side of the rear side wall of the supporting cylinder 2. The movable shaft 61 is located above the fixed cylinder 5. The lightweight rod frame 62 is fixedly installed on the outer surface of the movable shaft 61. The lightweight rod frame 62 can rotate with the movable shaft 61. The lightweight rod frame 62 passes through the opening 4, reducing the obstruction of the side wall of the supported cylinder 2. The front end of the lightweight rod frame 62 is fixedly installed with a fixed shaft 12, which can move with the lightweight rod frame 62. The gear 63 is fixedly installed on the outer surface of the movable shaft 61 and is located on the inner side of the lightweight rod frame 62. It can move with the lightweight rod frame 62. Positioning grooves are formed between the tooth blocks on the gear 63.
[0027] In addition, the support spring 64 is fixedly installed on the inner bottom wall of the fixed cylinder 5, and the positioning block 65 is fixedly installed on the top of the support spring 64. Under the elastic force of the support spring 64, the positioning block 65 can be lifted up, and the positioning block 65 is slidably connected to the top wall of the fixed cylinder 5. The positioning block 65 can move up and down on the top wall of the fixed cylinder 5. The space between the tooth blocks on the gear 63 is clamped with the positioning block 65. The space between the tooth blocks is the positioning groove, and the positioning block 65 is clamped into the positioning groove.
[0028] At the same time, the end side wall of the positioning block 65 is an inclined surface, so that the rotation of the gear 63 squeezes the positioning block 65 and can move downward, and then it is clamped into the next positioning groove for positioning. Due to the clamping of the positioning block 65, it is necessary to use force to rotate the lightweight rod frame 62. After the lightweight rod frame 62 is rotated, the height of the clamped PICC catheter can be adjusted, and it moves with the base 10 as the base point, avoiding damage to the PICC catheter caused by arbitrary pulling. The outer surface of the positioning block 65 is fixedly connected to a stopper 7 corresponding to the top wall of the fixed tube 5, which avoids the positioning block 65 from being completely moved out of the fixed tube 5, thereby playing a limiting role.
[0029] See also Figure 1 and Figure 6 A clamping assembly 13 is provided on the fixed shaft 12, and the clamping assembly 13 includes a clamping arm 131 and a connecting spring 132. The clamping arm 131 is rotatably connected to the outer surface of the fixed shaft 12. There are two clamping arms 131. The clamping portion of the clamping arm 131 is arc-shaped, which fits the shape of the PICC catheter and is adapted to the PICC catheter. An installation groove 14 is opened on the opposite sides of the two clamping arms 131. The connecting spring 132 is fixedly installed between the opposite sides of the two clamping arms 131. Under the elastic force of the connecting spring 132, the clamping portion of the lower clamping arm 131 can clamp the PICC catheter. The connecting spring 132 is installed in the installation groove 14 on the clamping arm 131.
[0030] When using this embodiment, first wrap the cuff 1 around the outer surface of the elbow and connect the two ends of the cuff 1 with Velcro 3, then install the base 10 into the cuff 1, then move the sub-buckle 112 from left to right to plug with the mother buckle 111, then pinch the top of the clamp arm 131 to open the clamping part of the clamp arm 131, then pass the PICC catheter through the clamping part of the clamp arm 131, release the clamp arm 131, and under the elastic force of the connecting spring 132, the two clamp arms 131 move closer to each other to clamp the PICC catheter, pull the lightweight rod frame 62 to rotate around the axis of the movable shaft 61, and drive the gear 63 to rotate. When the lightweight rod frame 62 drives the PICC catheter to move to a suitable angle and height, the positioning block 65 is inserted into the positioning groove formed between the tooth blocks on the outer surface of the gear 63, and the lightweight rod frame 62 is positioned to complete the maintenance of the PICC.
[0031] The beneficial effects of the above embodiments are:
[0032] The PICC maintenance auxiliary bracket is provided with an adjustment component 6. After use, the adjustment component 6 can pull the lightweight rod frame 62 to rotate around the axis of the movable shaft 61. At this time, the gear 63 is positioned and engaged by the positioning block 65 while rotating, forcing the positioning block 65 to move up and down. When the lightweight rod frame 62 is rotated to a suitable angle and height, the positioning block 65 is engaged in the positioning groove formed between the tooth blocks on the outer surface of the gear 63, so as to position the lightweight rod frame 62 and allow the lightweight rod frame to move with the base as the base point. In this way, the change of the angle and height of the PICC catheter is conducive to the smooth maintenance of the PICC, and the lightweight rod frame 62 is supported by the patient's own arm. The PICC catheter will not be greatly pulled due to the uncontrollable movement of the child during PICC maintenance, which can effectively prevent the pipeline from slipping due to the patient's failure to cooperate during the PICC maintenance process.
