Description

Implanted venous transfusion harbor does not have auxiliary fixture of needle

Technical Field

The utility model relates to the field of medical instruments, in particular to an auxiliary fixing device for an implantable venous transfusion port atraumatic needle.

Background

The implanted venous transfusion port is used as a new central venous catheter, has small influence on the daily life of a patient, does not damage the self image of the patient, and is more and more widely applied to clinic. When needing to reserve the not damaged needle through the infusion port and infusing, the nurse can directly pierce the not damaged needle and implant the subcutaneous infusion port body of patient, then uses aseptic applying ointment or plaster to fix. However, because the harbor is located at the chest wall (close to the armpit) of the patient, the atraumatic needle is easy to displace when the shoulder and arm of the patient move. The indwelling transfusion port is mostly a patient with advanced tumor, the patient can get slimmed day by day, and the subclavian pit is sunken to lead the non-invasive needle to be more difficult to fix. Thereby possibly causing the exosmosis of irritant drugs such as chemotherapy drugs and the like, increasing the pain and economic burden of patients, increasing the medical expenditure and reducing the satisfaction degree of the patients.

Referring to fig. 1 and fig. 2, the present embodiment provides an auxiliary fixing device for an atraumatic needle of an implantable venous transfusion port, including: the bottom of the bottom pad 1 is provided with a soft material and adhesive stickers, and the adhesive stickers are used for being stuck to the skin on two sides of the transfusion port; and the top cover is configured to be connected above the two bottom cushions 1 through a quick release structure. In this embodiment, the quick release structure includes the nylon hook strip on the upper surface of the bottom pad 1 and the nylon velvet strips 2 on both sides of the bottom of the top cover, and the nylon hook strip is connected with the nylon velvet strips 2. The cover has a transparent application 3 portion. The soft material comprises a sponge. Wherein, the nylon velvet ribbon 2 and the transparent application 3 are of an integrated structure. The two base pads 1 are equal in size and same in shape.

It is to be understood that a PORT is a closed infusion device that is fully implanted in the human body, including a catheter portion having a tip located in the superior vena cava and an injection site that is implanted subcutaneously.

The following is a detailed example of the product, which is composed of three parts, namely, two bottom cushions 1 and a top cover. All are sterilized and sealed.

Bottom pad 1: the bottom of the bottom pad 1 is provided with sponge and adhesive stickers, the stickers can be fixed on the skins at two sides of the harbor body, and the sponge can fill the fall between the harbor body and the surrounding skins. Because the fixed position of the bottom cushion 1 can be automatically adjusted according to the size of the port of the patient, the transfusion port and the atraumatic needle with various specifications can be matched for use. While the optimal puncture location can be marked. The surface is made of nylon hook belt material.

Top cover: the top cover is divided into a left part, a middle part and a right part, the bottoms of the left part and the right part are nylon velvet belts 2 which can be buckled with nylon hook belt materials on the surface of the bottom pad 1 (male and female hasps) to play a role in fixing. The middle part is transparent applying ointment or plaster 3 materials, also is convenient for the nurse to observe the not damaged needle puncture point condition after the laminating. Meanwhile, according to the relevant standards and guidelines of static therapy, the venous catheter which cannot observe the puncture point needs to be maintained every 2 days, the venous catheter which can observe the puncture point only needs to be maintained every 7 days, and the workload of nurses can be greatly reduced. The surface of the top cover is made of smooth material, and various sterile application pastes can be covered on the top to seal the puncture position of the atraumatic needle.

When the product is removed, the nylon hook belt and the nylon velvet belt 2 between the top cover and the bottom pad 1 are firstly uncovered, after the nondestructive needle is pulled out, the bottom pad 1 is soaked by alcohol cotton balls or cotton sheets, the viscose is dissolved, and then the bottom pad 1 is uncovered.

The product can be used when a needle without damage is put into the needle, and infusion can be carried out through the infusion port. The product is also retained in the process of retaining the atraumatic needle. The service life of each atraumatic needle is 7 days, and the product is replaced when the atraumatic needle needs to be replaced. The product is also removed when the atraumatic needle is pulled out.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
