Abstract

<P>PROBLEM TO BE SOLVED: To provide an easy and inexpensive vein protector capable of reducing such trouble as detachment of a catheter part caused by touching an obstacle, injury of the vein caused by bending limbs and unintentional removal of a catheter as the catheter indwelling in the vein is fixed with adhesive plasters for the intravenous injection. <P>SOLUTION: A soft transparent synthetic resin plate etc., is fixed in a cylindrical shape with adhesive tapes or hook and loop closures such as Velcro (R) materials at both ends. The synthetic resin plate has thickness with (or without) vent holes. The length of the synthetic resin plate can be easily adjusted by cutting with scissors, and the length is long enough to fix two joints at the same time. In another embodiment, the synthetic resin plate may be fixed from outside with Velcro (R) bands, etc., after formed in the cylindrical shape. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

The present invention relates to protection of limb veins used by medical personnel, and relates to an inexpensive and easy-to-wear device used to protect venous blood vessel damage caused by external contact and joint movement. is there.

A metal or flexible catheter connected to an infusion tube is used at a selected venous site of a patient's limb in order to supply blood and drug solution into the body from the vein. When a patient undergoing intravenous infusion treatment has to move to another location, for example, when the patient is transported from the accident site to a hospital, or moved from a hospital room to a laboratory, toilet, etc. Damage may occur. In addition, the same site may be rubbed with a bed cover, clothing or other article, resulting in partial or complete removal of the catheter. Various vein drip protection devices have been developed in the past. For example, Japanese Patent Application No. 11-2706, Japanese Patent Application No. 10-542811, and the like describe a vein protection device that protects only a vein drip site with a transparent cover and requires complicated labor for attachment. However, these devices have comprehensive features such as convenience, economic efficiency as a disposable product in consideration of infection due to body fluid adhesion, etc., and significant limitation of flexion due to simultaneous fixation of two joints based on anatomical and mechanical aspects. It cannot be dealt with as a protective device for a safe intravenous drip site.

Conventional catheter fixation at the site of intravenous injection is usually fixed with a bandage. This has the following problems. Due to venous fixation over a long period of time, catheter detachment, fluid leakage, vein damage, etc. occurred during body movement and movement. There are also many cases in which the catheter was unconsciously removed due to mental fatigue or consciousness opacification. In addition, considering the possibility of infection of medical supplies, the economics of disposable products must be considered. In the present invention, the above-mentioned problems are alleviated by fixing the joints simultaneously at a low cost and in a simple manner so that a slight movement of the patient does not affect the same part.

In order to solve the above problems, the present invention has the following configuration. A transparent synthetic resin plate with plasticity that can be easily cut with scissors according to the length of an individual's limb, and both ends can be fixed when rolled into a cylindrical shape with adhesive tape or Velcro (registered trademark) . Or it can be fixed with Velcro (trademark) band from the outside. In the state where it is formed in a cylindrical shape, the venous catheter insertion site for intravenous infusion is protected all around, reducing contact with obstacles around the body, and sufficient length to simultaneously fix the joints. By holding it, the mobility of the joint flexion can be remarkably limited with a slight resistance from the anatomical and mechanical viewpoints, and vein damage caused by the catheter can be prevented, and the protective cover is made of transparent soft synthetic resin As a result, the catheter insertion portion can be easily observed from the outside. Furthermore, since the structure is simple, it can be manufactured at low cost, and it can be used as a disposable product in consideration of the possibility of infection due to adhesion of body fluids or the like.

The present invention has the structure described above. The effects as described below are shown. Intravenous instillation in medicine occupies a very important position for treatment. Moreover, the treatment site may be used not only in the hospital but also in places where people exist, such as homes, ambulances, airplanes, and trains. In addition, the amount of the injection solution is large, and it is necessary to wear it for a long time. For this reason, it is important to prevent a movement for body movement and urination and accidental contact with the same site. When using the simple drip protector of the present invention, the drip injection site can be fixed simply by placing the product of the present invention under the drip injection site and rolling it into a cylindrical shape. It is effective in reducing accidents such as vein damage caused by bending. It can also alleviate similar anxiety during the patient's own infusion.

Embodiments will be described below with reference to the drawings. As shown in FIG. 1, the material is a soft synthetic resin plate that has a length capable of simultaneously fixing two joints having a certain thickness and can be easily cut with scissors or the like. It is also possible to provide a number of ventilation holes for ventilation. At the end, an adhesive tape is attached so that the cylindrical shape can be maintained. In FIG. 2, Velcro (registered trademark) material is vertically bonded to both ends, so that the diameter of the cylindrical shape can be determined with a higher degree of freedom. FIG. 3 is a view in which the end of the product of the invention is formed into a cylindrical shape by fixing the end with an adhesive tape. FIG. 4 is a view similarly fixed to a cylindrical shape by Velcro (registered trademark). Fig. 5 is a diagram in which a soft synthetic resin plate having a length capable of simultaneously fixing the two joints is laid under the limb after insertion of the venous catheter in an actual use situation. FIG. 6 is a diagram that protects the venipuncture part while forming a cylindrical shape according to the diameter of the patient's limb and fixing the joint. However, the present invention is not limited to the embodiments described above.
