Background
In medical surgery, basic clinical operations such as suturing, dressing change, and stitch removal are generally required for wounds, and medical tools used are suture needles and sutures. These basic suturing procedures add psychological burden and pain to the patient. In recent years, with the development of absorbable suture intradermal suturing technology, patients who pass intradermal suturing do not need to take out the suture, but still have problems such as contamination of the operation mouth, suture reaction, scar hyperplasia, and the like. The skin incision closure technique requires further renewal.
In the prior art, a medical adhesive applicator such as a skin adhesive is used for wound closure. The structure of the product is basically that medical glue such as skin adhesive is put into a sealed glass and other fragile material rubber storage tube, then the sealed glass rubber storage tube is put into a silica gel protective sleeve, when in use, the silica gel protective sleeve is pinched by hands, namely after the glass rubber storage tube is pinched, the medical glue such as skin adhesive flows into the silica gel protective sleeve, and simultaneously flows out from a port of the silica gel protective sleeve and is smeared at a skin wound position.
The existing smearing tool has the following problems:
1. the product needs to directly pinch the glass rubber storage tube in the silica gel protective sleeve with fingers by an operator in use, and the operator needs to directly and continuously squeeze the crushed glass rubber storage tube in the silica gel protective sleeve with fingers in the smearing process, so that the risk of finger pricking by crushed glass is still present even though the product is protected by the silica gel protective sleeve and the like;
2. when the skin adhesive is coated in the wound closing operation, the skin adhesive is not easy to be coated on the wound to be closed quickly and uniformly, and the repeated coating of the skin adhesive on the wound is extremely easy to be caused;
