Description

  The present invention relates to a water absorbent used for hemostasis, disinfection, drug application, and the like.

Conventionally, for example, in the medical field, organ hemostasis is generally performed by placing gauze or a gelatin sheet containing thrombin on or attaching to a bleeding part and applying pressure with a fingertip. However, since such a material has a flat shape, it is difficult to wipe fine portions. In particular, when used for hemostasis in surgery or the like, it is difficult to apply pressure to the target location, and the skin, mucous membrane, etc. may be damaged.
Utility Model Registration No.3051608

The problem to be solved by the present invention is to provide a medical water-absorbing body that can solve these conventional problems and can easily wipe fine portions.

The configuration of the present invention that solves this problem is as follows.
1) Cover a spherical core material having water absorption with a sheet material having water permeability, and fasten the middle of the coated sheet material under the core material to form a gripping part having a downward spread. Medical water-absorbing body 2 capable of absorbing water at the head portion above the stop portion 2) Medical water-absorbing device according to 1), wherein a hemostatic agent comprising gelatin or oxidized cellulose is releasably attached to the coated head portion of the sheet-like material. Body 3) Medical absorbent body 4) described in 1) above, wherein the covering bag of the sheet-like material is attached to the covering head part of the sheet-like material by pressure. 1) The medical absorbent body 5 described in 1) above, which is attached to the covering head and the opening of the inner bag is sealed with a release sheet. The core is provided with a recess, and the recess is located inside the gripping portion and the fastening portion. insertion space of a finger is formed in communication with the space, the 1) to 4) medical absorption according to any one Body 6) The medical absorbent body 7) according to any one of 1) to 5), wherein a slender string having a predetermined length is attached to the fastening portion or the gripping portion. 7) The fastening portions of the plurality of water absorbing bodies are taped together. The medical absorbent body according to any one of 1) to 6), which is connected to the medical absorbent body according to 7), wherein perforations are formed at positions between the respective absorbent bodies of the tape-like material.

  A cotton ball or gauze used in the surgical field, which is formed into a ball shape by stitching it with a thread, or a rolled tissue must be grasped with tweezers and the like because there is no gripping part. Easy to hurt. However, in the present invention, since the surface is smooth, it is hard to be damaged, and since it has a grip portion, it is easy to handle and easy to wipe off.

  In cotton balls, cotton wool, etc., fiber scraps tend to adhere to tissues, and in sensitive parts such as the conjunctiva of the eyeball and tissues in the body, residual fibers tend to cause inflammation. However, in the present invention, since it is coated with a sheet-like material, residual fibers are unlikely to remain on the body surface or the body surface.

  If the nasal discharge of influenza, SARS secretions, tears, etc. are wiped with a tissue, the infiltrated liquid may adhere to the fingertips and spread the infection. However, in the present invention, if the grasping portion is grasped, it can be wiped without touching the infectious secretions, and when throwing away, it is easier to throw away than wet and deformed tissue.

  After removing the gauze used for compression hemostasis at the time of laparotomy, when the collected gauze is less than the gauze used, it will look inside the abdominal cavity, but the infiltrated blood is the same color as the organ and difficult to find Sometimes. However, in the present invention, it is easy to specify the use of a non-permeable fastener for fastening the sheet-like material, and by identifying identification information such as numerals or alphabets on the fastener, the number of used parts can be easily identified. It becomes. In addition, if a long and narrow string is attached from the grip portion, the string can be easily collected by pulling the string from the surgical site, and the number of forgetting to collect is reduced.

  In addition, when the remaining gauze cannot be found by any means, conventionally, the site was specified by copying a thin wire embedded in the gauze to the X-ray. However, in the present invention, the X-ray radiopaque substance (metal)・ If ceramics are attached, it is easier than embedding a wire in gauze.

  Even when wiping off acids, alkalis, poisons, etc. using a cloth with a gloved hand, the liquid infiltrated during intermittent work may adhere to the glove and be exposed to low concentrations of volatile components. However, since it has a gripping part and is sucked by the head part at the tip, the above-mentioned phenomenon hardly occurs.

  As the core material of the present invention, a material having water absorption properties such as rounded paper, pulp, cotton, kenaf, and a polymer water-absorbing agent is used. Although the size depends on the application, for example, 2 to 5 cm is practical when used for hemostasis during surgery, and 1 to 2 cm is practical when used for wiping the eyeball or the like.

  As a sheet-like material (including a cloth-like material), a material having water permeability such as paper such as tissue paper, pulp, cotton, silk, nylon, acrylic, polyester, polyurethane, and porous perforated polyester sheet is used. It is done. The sheet itself may have water absorbency, and it is desirable that the sheet is less likely to generate fiber waste during use.

  In addition, a medicine-containing bag that is partially opened by compression may be attached to the coated head of the sheet-like material so that the medicine can be applied. As means for fastening, there are fixing with an adhesive or the like and fastening with a band-like fastening tool such as vinyl or rubber. If the lower part of the fastening portion of the sheet-like material is formed in a bellows shape, it is difficult to slide and easy to handle. Embodiments of the present invention will be specifically described below with reference to the drawings.
