Description

The present invention relates to a protective device for enabling a bath or the like by removing a pipe from a medication port while an indwelling needle and catheters are connected to a body surface.

  Regarding the indwelling needle used for medication, there is a problem of contamination when bathing or showering is required when the medication period is long. This is because germs may invade into the body from the portion where the indwelling needle is pierced with the skin by washing the body. As an invention corresponding to such a problem, for example, there is one disclosed in Japanese Patent Application Laid-Open No. 11-76401, and the invention of the same issue includes a flexible frame surrounding the periphery of the indwelling needle, a cover and a belt attached to the frame, And a belt fixing means, and it is proposed to cover the target portion with a cover with a frame. In another invention, means for securing waterproofness is provided by binding the arm with a belt instead of the frame. However, the waterproofness obtained by pressing the frame against the body surface or binding the arm with a belt as described in the invention of the same issue is extremely limited. It is not guaranteed to prevent situations such as dirt and invasion of bacteria.

  The situation is the same for a catheter that is inserted into the vascular system and placed with a thin tube connected to the body surface. When the catheter is intended for hemodialysis, the catheter is inserted from the body surface into the blood vessel in order to function as a means for extracting blood during dialysis treatment and returning it to the blood vessel. After the catheter is inserted into the blood vessel, the outlet portion of the catheter is protected with a dressing material such as gauze. However, if the dressing material gets wet, it is not preferable because germs easily propagate. The medication port of the catheter is also a place where bacteria can easily enter. For these reasons, there is still room for solving the problem of bacteria intrusion due to bathing, showering, etc. during use of an indwelling needle, a catheter or the like.

JP-A-11-76401

  The present invention has been made paying attention to the above-mentioned points, and its problem is to effectively solve the problems of waterproofing, dustproofing and antibacterial problems associated with connecting indwelling needles and catheters to the body surface. . Another object of the present invention is to provide a waterproof, dustproof, and antibacterial effect by separately protecting the indwelling needle, the portion connected to the body surface of the catheter, and the infusion needle of the indwelling needle and the catheter. Is to raise.

  In order to solve the above-described problems, the present invention provides a protective device for removing a pipe from a medication port while keeping an indwelling needle and catheters connected to a body surface, and enabling bathing and the like. A first protective means having a waterproof first covering member that covers a portion connected to the body, and a structure for watertightly fixing the first covering member to the body surface; an indwelling needle; and closure of catheters And a second protective means having a waterproof second covering member covering the prescription mouth and having a structure for fixing the second covering member to the body surface in a watertight manner. Is.

Indwelling needles and catheters are different in that the indwelling needle is connected to the blood vessel by needle puncture, and the catheter is connected to the blood vessel by a thin pipe. Since they are the same, the present invention is directed to indwelling needles, catheters and similar devices for connection to blood vessels. This is because those connected to blood vessels from the outside are common in that they have a problem of vulnerability to invasion of bacteria into the body. In such an indwelling needle and catheter, since the drug solution is supplied by connecting the pipe to the medication port, the pipe can be removed if necessary, and the medication port of the catheter from which the pipe has been removed is closed with caps.

The first covering member first covers portions of the indwelling needle and catheters that are connected to the body surface. The first covering member must be waterproof. It is desirable that the first covering member can cover a portion connected to the body surface of the indwelling needle and the catheters and has flexibility so as to follow the movement over the portion after covering. It is. The first covering member is watertightly fixed to the body surface while covering the portion connected to the body surface of the indwelling needle and catheters. When the first covering member is formed of a sheet material, the first covering member may be bonded along the edge of the sheet material, but it is desirable that such an adhesive portion also has watertight performance. For example, a pressure-sensitive adhesive layer is provided along the edge of the inner surface of the sheet-like first covering member to serve as an adhesive portion, and a release paper is attached to the pressure-sensitive adhesive layer or placed on a mount that has been processed so as to be easily peeled off What affixed the 1st covering member in the adhesion part satisfies all requirements as the 1st protection means.

  The infusion needle and the catheter, which are closed in advance, that is, after the pipe for supplying the medical solution is removed, are closed by the second covering member. It is desired that the second covering member is also waterproof. It is sufficient if the second covering member can cover only the infusion needle and the medication port of the catheters. However, it is also possible to take a configuration that further covers the first protective means covering the indwelling needle and the catheters, in which case the second covering member not only covers the medication port, but also the indwelling needle and the catheters. It will take the structure which covers the part connected with the body surface twice.

  The second covering member may have a bag-like structure covering the indwelling needle and the medication port of the catheters. Both the indwelling needle and the catheter protrude from the part connected to the body surface, and the second covering member that covers this in a watertight manner preferably has a bag-like structure. By closing the bag mouth of the bag-like structure, Almost complete watertight protection against water will be achieved. As described above, the bag-like structure of the second covering member is advantageous in that the indwelling needle protruding from the portion connected to the body surface and the catheter are wrapped. As can be seen from the first embodiment shown in FIG. 2, it is also advantageous in that the entire first protection means can be completely covered. The structure which covers the part connected with the body surface of an indwelling needle and catheters by this double has already been demonstrated.

  The structure for watertightly fixing the second cover part to the body surface need not be the same as the adhesive part of the first cover part. As already explained, there are two cases where the second cover part covers only the part connected to the body surface of the indwelling needle and catheters, and the second cover part covers only the first protection means. This is because the means for closing the open portion of the second cover and adhering to the body surface can naturally be different. In any case, it is natural that watertight adhesion should be achieved in fixing the second cover portion.

  Since the present invention is constructed and operates as described above, the problems of waterproofing, dustproofing and antibacterial problems associated with connecting indwelling needles and catheters to the body surface are almost completely solved. Even inside, by removing the chemical solution pipe and attaching the apparatus of the present invention, it becomes possible to take a bath without worrying about the problem of invasion of bacteria with water and dirt. In particular, in the present invention, by protecting the indwelling needle and the part connected to the body surface of the catheter, and the infusion needle and the administration port of the catheter separately, respectively, it is possible to improve the integrity of waterproofing, dustproofing and antibacterial properties. it can.

Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 includes a plan view showing a portion related to the first protection means 10 in Example 1 of the protection device for an indwelling needle according to the present invention and a cross-sectional view in two orthogonal directions.
