Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a PICC external fixation protective sleeve. Background Technology

[0002] PICC (Peripherally Inserted Central Catheter) placement is a technique that involves inserting a central venous catheter into a peripheral vein. The catheter tip is positioned in the superior vena cava for intravenous infusion and transfusion therapy. During the indwelling period, there is no need to puncture the skin for each infusion; simply insert a needle directly into the heparin cap at the catheter tip and flush the catheter with normal saline. When not infusion is being performed, a nurse needs to perform weekly catheter maintenance and change the dressing. This completely eliminates pain caused by puncture and drug irritation, making the catheter safer and more comfortable to carry, allowing for easy completion of the entire treatment process, and fundamentally improving the patient's quality of life. Because the PICC catheter remains in the body for a relatively long time, auxiliary tools are needed to assist in securing the PICC connector.

[0003] Chinese patent CN210903667U discloses a fixation dressing for exposed needleless infusion connectors of PICC catheters. The dressing includes a pocket-shaped dressing bag with a cavity for the needleless infusion connector and a sheet-like dressing that can be adhesively fixed to the patient's hand or arm. The end of the needleless infusion connector can be inserted through the opening of the dressing bag and locked into the cavity. When the dressing bag is adhesively fixed to the patient's hand, the needleless infusion connector is simultaneously fixed and limited in place at the patient's hand or arm. This invention aims to provide a simpler and more efficient protection and fixation for needleless infusion connectors, thereby improving patient comfort.

[0004] Although the device uses a pouch on the patient's arm to hold the PICC connector when not in use, the connector may still dislodge during patient movement, indicating a need for improved stability. During normal infusion, the PICC connector must be removed before connecting it to the infusion tubing; therefore, the device does not function during the infusion process.

[0005] Therefore, a protective sleeve for PICC external fixation is needed. Utility Model Content

[0006] The purpose of this utility model is to provide an external fixing protective sleeve for PICC to solve the problem of the risk of PICC connector falling off mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a PICC external fixation protective sleeve, comprising a bandage and a rubber sheet, wherein a protective mechanism is provided on the top surface of the rubber sheet, and a stabilizing mechanism is fixedly installed on the top surface of the rubber sheet; the stabilizing mechanism includes a fixing block, the bottom end of the fixing block being fixedly connected to the top surface of the rubber sheet, an installation strip being overlapped and installed on the top surface of the rubber sheet, a slot being fixedly opened on the bottom end of the installation strip, the inner wall of the slot being adapted to the side of the fixing block, a limiting groove being fixedly opened on the top surface of the installation strip, a through hole being opened vertically through the rubber sheet, a limiting component being fixedly installed on the top surface of the rubber sheet, a connecting sleeve being fixedly installed on the end face of the limiting component, an installation groove being fixedly opened on the top surface of the limiting component, and an observation window being fixedly installed on the inner wall of the installation groove, the observation window being made of acrylic material.

[0008] Preferably, the bandage has a left ventilation hole extending vertically through the left side, a right ventilation hole extending vertically through the right side, a second Velcro fastener fixedly installed on the top surface of the bandage, and a first Velcro fastener fixedly installed on the bottom surface of the bandage.

[0009] Preferably, the side of the first hook and loop fastener is adapted to the side of the second hook and loop fastener, and the bandage has a through hole extending through it vertically, with the inner wall of the through hole being fixedly connected to the side of the rubber sheet.

[0010] Preferably, the protective mechanism includes a protective belt, a plurality of through holes are fixedly opened on the side of the protective belt, a connecting wire is provided on the inner wall of the through hole, the connecting wire is fixedly connected to the rubber sheet, a connecting block is fixedly opened on the side of the protective belt, and a third Velcro is fixedly installed on the side of the connecting block.

[0011] Preferably, a fourth Velcro fastener is fixedly installed on the top surface of the rubber sheet, the fourth Velcro fastener is connected to the third Velcro fastener, a rubber plate is fixedly installed on the bottom surface of the rubber sheet, and a through hole is opened through the top and bottom of the rubber sheet, the through hole corresponding to the bottom surface of the limiting member.

[0012] Preferably, the protective belt is made of stretchable fabric and is breathable, and the connecting block can be pulled and adjusted to adjust the adhesion position and angle with the fourth Velcro.

[0013] Preferably, the number of fixing blocks and bayonets is six.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) When using this PICC external fixation protective sleeve, first align the through hole on the rubber plate with the infusion site and adhere the rubber plate to the infusion site. Then, wrap the bandage around the patient's infusion site. At this time, insert the infusion tube into the connecting sleeve and engage it with the limiting piece to connect the infusion tube to the infusion device. Further install the infusion tube with the limiting groove, and then engage the snap-fit ​​on the bottom end of the mounting strip with the fixing block to improve the stability of the connection between the infusion tube and the connecting sleeve. This can improve the stability and practicality of the device for the PCII connector, and can also improve the protection of the patient through the bandage.

[0016] 2) When the bandage is connected to the patient and the infusion tube is connected to the connecting sleeve, the connecting block is pulled and moved to the side of the fourth Velcro, so that the third Velcro on the side of the connecting block is connected to the fourth Velcro, thus protecting the infusion tube and the PICC connector; and the device can improve the connection stability of the device by adapting the first Velcro and the second Velcro, thereby improving the protection and practicality of the device for the PICC connector.
