Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a PICC connector with a protection function. Background Art

[0002] PICCs, short for Peripherally Inserted Central Venous Catheters, are peripherally inserted central venous catheters (PICCs). These catheters are inserted through a peripheral arm vein (such as the basilic, median cubital, or cephalic veins), with the tip positioned in the superior vena cava or subclavian vein near the heart. They are used to provide patients with medium- to long-term intravenous infusion therapy, with a maximum retention period of one year.

[0003] During use, PICC connectors can cause pressure injuries at the attachment site due to prolonged contact with the skin. However, current clinical research has primarily focused on improving disinfection methods and disinfectant selection, or applying pressure-relieving patches to the skin to alleviate medical device-related pressure injuries caused by PICC connectors and PICC cannulas. The concept of protecting PICC connectors has not been mentioned. Therefore, the present invention proposes a PICC connector with protective functions. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a PICC connector with a reverse protection function.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a PICC connector with a reverse protection function, comprising a connector body and a backing plate, wherein an annular frame plate is sleeved on the surface of one end of the connector body away from its own threaded connector, and a connecting component is provided on the bottom of the annular frame plate and one side of the upper surface of the backing plate, a foam dressing is fixed on the lower surface of the backing plate, a strap is fixedly connected to one side of the backing plate, and an adhesive area is provided on the surface of the strap away from the backing plate.

[0006] Furthermore, the pad is designed to be arc-shaped, and the foam dressing fits closely to human skin.

[0007] Furthermore, a locking bolt passes through and is threadedly connected to the top wall of the annular frame plate, and the bottom end of the locking bolt is in contact with the surface of the joint body.

[0008] Furthermore, the connecting assembly includes a shaft sleeve fixed on the upper surface of the pad and an insertion shaft fixed on the lower surface of the annular frame plate, and the insertion shaft is located inside the shaft sleeve and is rotatably connected to the shaft sleeve.

[0009] Furthermore, the outer side wall of the insert shaft is provided with an annular ridge, and the inner side wall of the sleeve is provided with an annular groove for clamping the annular ridge.

[0010] Furthermore, the surface of the adhesive area is provided with 3M glue.

[0011] Beneficial effects of the utility model:

[0012] When in use, the present invention comprises a PICC connector with a protective function, comprising a connector body and a backing plate. An annular frame plate is sleeved on the surface of the connector body, which is connected to the backing plate via a connecting assembly. A foam dressing is provided on the lower surface of the backing plate. Therefore, when the PICC connector is in use, the foam dressing on the lower surface of the backing plate contacts the patient's skin, thereby increasing the contact area and preventing pressure damage caused by long-term contact between the connector and the skin, thereby achieving skin protection. Furthermore, the annular frame plate and the connector body can be rotated on the backing plate surface via the connecting assembly, facilitating the installation of the threaded connector of the connector body.

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figure 1-Figure 3As shown, it relates to a PICC connector with a protective function, including a connector body 1 and a backing plate 2. The surface of the connector body 1 at one end away from its own threaded connector is sleeved with an annular frame plate 3, and the bottom of the annular frame plate 3 and one side of the upper surface of the backing plate 2 are jointly provided with a connecting component 5, a foam dressing 6 is fixed to the lower surface of the backing plate 2, and a strap 7 is fixedly connected to one side of the backing plate 2, and the surface of the strap 7 away from the backing plate 2 is provided with an adhesive area 8.

[0021] The backing plate 2 is designed to be arc-shaped, and the foam dressing 6 fits the human skin.

[0022] The arc-shaped design of the pad 2 can better fit the curvature of the patient's arm. The pad 2 in contact with the skin can increase the contact area with the skin, avoiding pressure damage to the skin caused by the connector body 1. Secondly, the contact between the foam dressing 6 and the skin can increase comfort.

[0023] A locking bolt 4 is passed through the top wall of the annular frame plate 3 and is threadedly connected thereto, and the bottom end of the locking bolt 4 is in contact with the surface of the joint body 1 .

[0024] When the joint body 1 is located inside the annular frame plate 3 , the locking bolts 4 can be tightened to fix the joint body 1 , thereby achieving assembly of the joint body 1 and the annular frame plate 3 .

[0025] The connecting assembly 5 includes a shaft sleeve 51 fixed to the upper surface of the backing plate 2 and an insertion shaft 52 fixed to the lower surface of the annular frame plate 3. The insertion shaft 52 is located inside the shaft sleeve 51 and is rotatably connected to the shaft sleeve 51.

[0026] By rotating the plug shaft 52 in the sleeve 51, the annular frame plate 3 and the joint body 1 can rotate on the surface of the pad 2, so that when the pipe is connected to the joint body 1, the angle of the threaded connection head of the joint body 1 can be adjusted, making installation more convenient.

[0027] An annular ridge 53 is provided on the outer side wall of the insertion shaft 52 , and an annular groove 54 for clamping the annular ridge 53 is provided on the inner side wall of the shaft sleeve 51 .

[0028] When the insertion shaft 52 is inserted into the shaft sleeve 51 , the annular ridge 53 can be locked into the annular groove 54 to prevent the insertion shaft 52 from being separated from the shaft sleeve 51 .

[0029] 3M glue is provided on the surface of the pasting area 8. After the pad 2 is placed on the patient's skin, the strap 7 can be passed around the patient's arm, and then the side with 3M glue is attached to the other side surface of the pad 2 to achieve the fixing of the pad 2.

[0030] Working principle: first tear off the release paper on the 3M glue in the adhesive area 8, then wrap the strap 7 around the arm, and use 3M glue to fix it to the other side of the pad 2, so that the pad 2 is fixed on the surface of the patient's arm. At this time, the foam dressing 6 is in contact with the patient's skin, which can play a buffering role. The connector body 1 does not contact the skin to avoid pressure injuries.

[0031] The preferred embodiments of the present invention disclosed above are intended only to help illustrate the present invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the present invention to specific embodiments. Obviously, numerous modifications and variations are possible based on the contents of this specification. These embodiments are selected and described in detail in this specification to better explain the principles and practical applications of the present invention, thereby enabling those skilled in the art to better understand and utilize the present invention. The present invention is limited only by the claims and their full scope and equivalents.
