Abstract

The application provides a skin stretching device, which comprises a main body made of plastic cloth, wherein the main body can be bent to form a cylinder body; when the cartridge is formed, the first edge and the second edge of the body are brought close to each other and kept at a predetermined distance, forming a puncture point emergence opening; hospital glues are respectively formed on the lower sides of the first edge and the second edge of the main body, so that after the main body is wrapped on the forearm of a patient, the first edge and the second edge of the main body are fixed near a point to be punctured; an air bag extending along the length direction of the cylinder is formed at the inner side of the main body; the air bag is positioned right below the puncture point exposure port; the air bag is connected with a riff joint through a pipeline so as to use an injector to inject air into the air bag through the riff joint.

Description

Leather stretching device

Technical Field

The utility model relates to a medical instrument, in particular to a skin stretching device.

Background

For elderly patients, the skin is more flabby; the skin and underlying blood vessels are subject to relative movement, which presents difficulties in accurate venipuncture, often requiring multiple punctures to accurately penetrate the blood vessel. In clinical practice, if the hands are sufficient, the skin is tensioned from two opposite directions of the extension direction of the forearm of one nurse, and the other nurse punctures the skin; in the case of a single person, a nurse typically holds one hand of the nurse on the opposite side of the point to be punctured and pulls or lifts the skin on the rear side of the forearm in a direction perpendicular to the extending direction of the forearm, so that the skin on the front side of the forearm at the point to be punctured is stretched and the puncture is performed.

There are also patents addressing this problem, which typically employ two clip devices, pulling on opposite defensive lines, or lifting or pulling the skin up behind the lower arm.

For the current patents, the similar parts are all tightened at a relatively far position from the puncture site, so that a large range of tightening operations are inevitably needed to make the skin at the puncture site in a tightened state. The larger range of tightening operations creates unnecessary tightening, increasing patient discomfort.

SUMMERY OF THE UTILITY MODEL

In view of the above problems, the present application aims to provide a skin stretching device which can perform a stretching operation in the vicinity as close as possible to a puncture point, and minimize discomfort of a patient.

The skin stretching device comprises a main body made of plastic cloth, wherein the main body can be bent to form a cylinder body; when the cartridge is formed, the first edge and the second edge of the body are brought close to each other and kept at a predetermined distance, forming a puncture point emergence opening; hospital glues are respectively formed on the lower sides of the first edge and the second edge of the main body, so that after the main body is wrapped on the forearm of a patient, the first edge and the second edge of the main body are fixed near a point to be punctured; an air bag extending along the length direction of the cylinder is formed at the inner side of the main body; the air bag is positioned right below the puncture point exposure port; the air bag is connected with a riff joint through a pipeline so as to use an injector to inject air into the air bag through the riff joint.

Preferably, the first end of the barrel has a diameter smaller than the diameter of the second end.

The first edge and the second edge of the cylinder body are respectively adhered to two sides of the point to be punctured nearby, so that the skin of the patient needing to be tightened is consistent with the actually tightened skin to the greatest extent; avoiding unnecessary skin from being tightened and reducing the discomfort of the patient.

Detailed Description

Hereinafter, the skin stretching device of the present application will be described in detail with reference to the accompanying drawings.

The skin stretcher of the present application includes a main body 10 made of plastic cloth.

The body 10 can be bent to form a cylinder; when the cartridge is formed, the first and second edges of the body 10 approach each other and maintain a predetermined distance, forming a puncture point exposing port 11; the lower sides of the first and second edges of the main body are formed with hospital glues 12, respectively, to fix the first and second edges of the main body 10 near the point to be punctured after the main body 10 is wrapped on the forearm of the patient.

An airbag 13 formed inside the body 10 to extend in the longitudinal direction of the cylinder; the air bag 13 is positioned right below the puncture point exposure port 11; the bladder 13 is connected by tubing to a riffle 14 for injecting gas into the bladder through the riffle using a syringe.

The first end of the cartridge 10 has a smaller diameter than the second end so that the cartridge is formed in a frustum shape to fit the basic contour of an arm as much as possible.

When in use, after the puncture point of a patient is determined, the main body surrounds the forearm of the patient; then adhering the first edge of the main body to the first side of the point to be punctured and adhering the second edge of the main body to the second side of the point to be punctured; the air bag is connected with the rift joint through the injector, and gas is injected into the air bag; the air bag starts to expand after the gas is injected, so that the skin near the point to be punctured is tightened by the first edge and the second edge which are stuck on the air bag towards the direction of the air bag, and the puncturing operation is convenient for nurses.

Claims

1. A skin stretching device is characterized by comprising a main body made of plastic cloth, wherein the main body can be bent to form a cylinder body; when the cartridge is formed, the first edge and the second edge of the body are brought close to each other and kept at a predetermined distance, forming a puncture point emergence opening; hospital glues are respectively formed on the lower sides of the first edge and the second edge of the main body, so that after the main body is wrapped on the forearm of a patient, the first edge and the second edge of the main body are fixed near a point to be punctured; an air bag extending along the length direction of the cylinder is formed at the inner side of the main body; the air bag is positioned right below the puncture point exposure port; the air bag is connected with a riff joint through a pipeline so as to use an injector to inject air into the air bag through the riff joint.

2. The skin stretcher of claim 1 wherein:

the first end of the barrel has a diameter less than the diameter of the second end.
