Description

  The present invention relates to a protective cover that is optimal for use during artificial dialysis, infusion, blood transfusion, blood donation, etc. (hereinafter referred to as artificial dialysis, etc.).

  Conventionally, when performing artificial dialysis on the patient's arm, a needle is inserted into a predetermined part (eg, arm) of the patient who is in a supine posture on the bed, and a certain amount of artificial dialysis is administered intravenously over a long period of time. Yes. At the time of this treatment, it is necessary to fix the needle and the tube communicating with the needle, for example, to the arm so that the needle does not inadvertently come off from the arm, and to monitor for abnormalities such as chemical leakage and bleeding. .

In particular, since artificial dialysis treatment takes a long time of 4 to 5 hours, it is necessary to monitor whether there is bleeding due to needle removal, bleeding from the puncture portion, leakage of a drug solution, or the like. Usually, nurses and the like regularly confirm that there is no leakage or bleeding due to missing needles. Thus, in order to easily and quickly confirm the safety of an artificial dialysis state by a nurse or the like, it is necessary to keep the patient's arm exposed so that it can be visually observed at all times. For example, if a patient is left for a long time with his arms exposed, the patient may feel cold because of weakness, anemia, etc. even if the room is maintained at an appropriate temperature by an air conditioner. The current situation is that there are obstacles to the observation of bleeding accidents, such as patients covering their arms with towels or blankets, and nurses wrapping sheets around their arms.

Because dialysis treatment takes a long time, patients may inadvertently move their arms or pull out the needle. Especially, elderly people and patients with dementia may be able to remove themselves. It is necessary to consider safety.

Conventionally, a drip protector for protecting the needle insertion portion and preventing self-extraction is known (for example,
Patent Document 1). In such a protector, a protective member made of a rectangular cloth width is detachably attached to the arm with a hook-and-loop fastener (see, for example, Patent Document 1).

Utility Model Registration No. 3 14 2147

Since the drip protector described in Patent Document 1 has a configuration in which a protective member made of a rectangular cloth is attached to the arm, it is possible to protect the needle insertion part and prevent self-extraction to some extent. However, since the needle insertion part is completely covered with a protective member such as a towel, a nurse or the like cannot always visually observe the needle insertion part. There was a problem that the work of attaching and detaching was necessary and the handling was troublesome. Furthermore, this protective device has a problem that it cannot be washed or disinfected at home due to its structure. In addition, because of the complicated structure and the replacement part, it is expensive, and there is also a problem that the economic burden is large for many dialysis patients who are aging. In addition, since non-hygroscopic materials are used, there is a risk that discovery of blood leakage will be delayed, especially during dialysis.

Therefore, the present invention is excellent in heat retention and safety when performing artificial dialysis, etc., is inexpensive, can be washed and disinfected at home, and finds leakage of blood etc. while maintaining permeability of blood in the fabric part. It is an object to provide a protective cover that can be easily used by nurses and the like with ease.

The present invention has been made to solve the above-mentioned problems, and the protective cover of the present invention includes a cover main body having a flexibility for detachably covering a treatment site of a patient, and a portion facing the treatment site. And a connecting means for detachably connecting both edge sides of the cover main body so as to form the cover main body in a cylindrical shape.

Since the protective cover of the present invention is provided with a transparent window portion, a nurse or the like can always see the treatment site and can monitor the state of artificial dialysis or the like. In addition, it is safe because artificial dialysis and the like can be seen through a transparent window. In addition, since the protective cover covers a portion to be worn such as an arm, cold air from the air conditioner can be prevented.

In the protective cover, there is provided a throttle means for restricting the opening portions at both ends of the cylindrical cover body. In such a case, the opening at both ends of the cover main body can be appropriately squeezed, so that the heat retaining property is further excellent. In addition, since the opening is squeezed with a string or the like, a hand can be put in from the opening at both ends of the cover body, and the needle or tube cannot be inadvertently touched by an elderly person or a patient with dementia, thereby reducing bleeding accidents.

In the protective cover, the window portion has a total area of 20 to 20% on one side of the cover body.
It is set to 65% and is provided on one side to which the cover body is connected.

The present invention includes a flexible cover body, a transparent window provided at a portion facing a puncturable site, and connection means for connecting both edges of the cover body. It is excellent in heat retention and safety and can be used easily and safely.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described in detail with reference to the accompanying drawings.

  A protective cover 1 according to the first embodiment shown in FIGS. 1 (a), 1 (b), and 2 is a cover body 2 that covers a patient's arm that requires artificial dialysis, and a transparent appearance that allows the patient to see the peripheral area of the artificial dialysis. Alternatively, the window portion 3 shielded by the translucent window sheet 4, the connecting means 5 for connecting the left and right ends of the cover body 2, and the throttle means 6 (6A, 6B) for narrowing the front and rear ends of the cover body 2 in the contraction direction. ) And are provided.

  The protective cover 1 can be formed into a cylindrical shape that is wound around the patient's arm and wound along the patient's arm from the state of being expanded into a substantially flat rectangular shape as shown in FIG. The window sheet 4, the connecting means 5, and the squeezing means 6 are all made of a highly flexible material.

  Covering one arm to be instilled with the protective cover 1 acts such as turning an artificial dialysis patient over, the dialysis patient scratching the artificial dialysis site due to itching around the dialysis site of the arm, and unconsciously artificial dialysis The dialysis needle and the front end of the dialysis tube are configured not to be removed from the dialysis site of the arm even if an attempt to remove the needle and the dialysis tube is performed. .

  The window part 3 is for an artificial dialysis patient, a nurse, and the like to check whether the needle for artificial dialysis and the tube for artificial dialysis are not detached from the needle insertion site with the protective cover 1 attached. For this reason, the window portion 3 is provided on the surface of the cover body 2 that is offset to the left or right. When the protective cover 1 is attached to the arm so that the window 3 is in this position, the connecting means 5 is oriented so that an artificial dialysis patient or the like can easily operate with the other hand. The window 3 is set to 20 to 85%, preferably 30 to 75% of the total area on one side of the cover body 2, and is provided on one side of the cover body 2. If the area is less than 20%, the area of the needle insertion site is small, and the needle piercing site is limited, which may hinder treatment such as artificial dialysis. On the other hand, if the area exceeds 85%, the touch will be reduced. In either case, it becomes worse, and the heat retention and durability deteriorate.

  The connecting means 5 can connect the left and right end portions 5a, 5b to maintain a cylindrical state in which the protective cover 1 is wound around the arm.

  The throttling means 6 (6A, 6B) is configured such that the front end of the protective cover 1 attached to the arm is lightly fixed around the wrist, and the rear end is lightly fixed to the arm so that the protective cover 1 is inadvertently displaced or detached. In this way, it is possible to prevent lateral deviation or the like.

  The size of the protective cover 1 unfolded in the flat state shown in FIGS. 1A, 1B and 2 is, according to the first prototype by the inventor, the overall width W35 cm in the lateral direction shown in FIG. The overall length L in the longitudinal direction (front-rear direction) is 40 cm. This size assumes a protective cover 1 having a size that substantially covers the entire arm (upper arm and forearm) of an adult, but these dimensions do not limit the present invention. For example, it may be a protective cover for children with a reduced size according to the size of the child's arm, although it is not shown, it can also be a short protective cover that protects only the forearm part of an artificial dialysis patient It is.

  According to the prototype described above, the window portion 3 has a lateral width X of about 15 cm and a front-rear width Y of about 26 cm. However, these dimensions do not limit the present invention. As long as the above-mentioned confirmation can be performed, a smaller window 3 may be used.

  Since the window part 3 is provided in the substantially up-down symmetrical position of the protective sheet 1, the protective sheet 1 can be used without making the up-down direction a problem.

  Since the cover main body 2 directly touches the arm of an artificial dialysis patient, a fabric having a good touch is used. For example, a fabric made of a pile-woven fabric that is often used as a towel fabric is an optimal fabric in that it has a good touch and is excellent in moisture absorption and liquid absorption such as sweat and blood.

  The protective cover 1 has a cover body 2 having a two-layer structure rather than a single-layer structure in order to have one of the main functions of keeping the arm warm and cold by receiving the outside air and the cold air of the air conditioner during cold weather. It is preferable that In the present embodiment, the two-layer structure is formed by folding the dough in half. Other fabrics suitable for the cover body 2 include plain-woven cotton cloth, nonwoven fabric, and the like. Since these fabrics are usually thin, it is preferable that the cover body 2 be stacked in two or more sheets. . You may make it accommodate heat insulating materials, such as absorbent cotton, between two piled cloth. Moreover, you may make it hold | maintain the activated carbon fine powder which has an antibacterial and bactericidal agent, or an odor adsorption function and a far-red function to the fabric fiber used for the cover main body 2. FIG.

  The cover body 2 may be made of a thin fabric, but what kind of fabric is used is appropriate in consideration of the above-described heat retention, heat dissipation near the affected area, prevention of stuffiness, season of use, etc. Selected dough. For example, the cover body 2 made of paper fabric with excellent flexibility is a protective cover that can be repeatedly washed and sterilized at home, which is excellent in terms of economy and hygiene in terms of material cost and cutting by Thomson processing. It becomes 1.

  Although not shown, it is possible to make the cover body 2 with two or three or more fabrics piled up, and two or more fabrics or nonwoven fabrics having different materials and woven structures are combined appropriately. It is also possible to make the cover body 2 overlapped. When the fabric used for the cover body 2 is a thermoplastic synthetic resin sheet, a woven fabric or a nonwoven fabric made of a thermoplastic synthetic fiber, laminated fabric around the cover body 2 by high frequency welding instead of stitching described later Can be welded.

  As the transparent or translucent window sheet 4 attached to the window part 3, as an optimum material to be used, a transparent or translucent polyvinyl chloride or polyethylene sheet having high antibacterial and antistatic properties with high flexibility can be mentioned. It is done. The window sheet 4 has sufficient strength to withstand the above-described actions such as scratching, washing of the protective cover 1, and folding of the protective cover 1 during storage. The window 3 is not particularly limited as long as the inside can be visually confirmed from the outside, and examples thereof include a net or the like in addition to a transparent or translucent sheet.
