Technical Field
The invention relates to the technical field of medical instruments, in particular to a medical skin preparation knife capable of preventing cutting injuries.
Background
The existing medical skin preparation knife is similar to a manual T-shaped shaver, when medical staff open a protective cover, an exposed blade easily scratches the medical staff, and in addition, the blades in the existing skin preparation knife are fixedly arranged, although the hair at the skin preparation position can be shaved off by the blades arranged in the way, when the hair of 0.5-2mm needs to be reserved in a special situation, the existing skin preparation knife cannot meet the requirements because the blades cannot be adjusted.
Disclosure of Invention
The invention provides a medical skin preparation knife capable of preventing cutting injuries, and aims to solve the problem that medical staff are easily scratched when a blade of an existing skin preparation knife is exposed.
In order to achieve the purpose, the technical scheme of the invention is as follows:
the utility model provides a medical skin preparation sword of anti-cutting wound, includes handle of a knife, mount pad, blade, goes up gland and holding down plate, the blade is located the gland, be equipped with the gliding actuating mechanism of drive blade along its edge of a knife direction of perpendicular to on the mount pad, seted up the spout on the long limit's of top board lateral wall, the spout bottom is seted up jaggedly, is equipped with the flexbile plate in the spout, is fixed with the spliced pole between blade and the flexbile plate, and the spliced pole is located the breach.
The technical principle and the effect of the technical scheme are as follows:
1. in this scheme preserved skin knife before the use, the blade is located inside the upper cover, therefore medical personnel when opening the protective cover on the preserved skin knife, the blade can not cause the danger of incised wound to medical personnel anymore, has eliminated the potential safety hazard of current medical preserved skin knife.
2. Drive the blade through actuating mechanism in this scheme and slide along perpendicular to edge of a knife direction, just so can adjust the edge of a knife of blade according to the skin preparation needs and stretch out the distance of gland to be adapted to different operation requirements, in addition when adjusting the blade, the blade slides and can drive the spliced pole and remove, thereby makes the flexor stretch out the spout, compresses tightly the blade, and the medical personnel's of being convenient for skin preparation is handled.
Further, the length of the flexible plate is not less than the length of the blade.
Has the advantages that: so that the flexible plate can shield the sliding-out part of the blade.
Further, the mounting seat is of a hollow structure, and the driving mechanism is located in the mounting seat.
Has the advantages that: this is so arranged that the whole dermatome is of a relatively simple construction from the point of view of appearance, without complex parts being located outside the dermatome, thereby affecting the skin preparation.
Furthermore, actuating mechanism includes bull stick and swing post, the bull stick rotates to be connected on the mount pad, the bull stick is on a parallel with the sword mouth limit of blade, swing post one end is fixed on the bull stick, and one end is fixed in the bottom of blade.
Has the advantages that: through rotating the bull stick, the bull stick rotates along with the bull stick is synchronous, because the blade has certain deformability, the situation of perk slightly upwards probably appears in the tool edge department of blade, and the flexible sheet roll-off this moment not only shelters from the blade of roll-off, also plays the effect of pressing the blade simultaneously.
Furthermore, one end of the rotating rod penetrates through the mounting seat, and a knob is fixed at one end of the rotating rod, which extends out of the mounting seat.
Has the advantages that: the knob is arranged to facilitate the medical staff to rotate the rotating rod, thereby adjusting the blade.
Further, the cross section of the upper gland is in an arc shape protruding upwards.
Has the advantages that: set up the gland into the arc and make, go up the gland and only both sides compress tightly on the blade, reduce the area of contact of gland and blade, make the blade easily slide.
Furthermore, the lower pressing plate is in a strip shape, and a plurality of comb teeth distributed at intervals are arranged on the side edge of the lower pressing plate in the length direction.
Has the advantages that: the comb teeth are arranged to prevent the blade from directly contacting the skin of a patient, so that potential safety hazards are increased.
Further, the handle of a knife is hollow structure, is equipped with the disinfection bag in the handle of a knife, and disinfection bag top intercommunication has the drain pipe.
Has the advantages that: through setting up disinfection bag and drain pipe, through the antiseptic solution direction broach department in the drain pipe will disinfect the bag to carry out disinfection treatment to patient's preserved skin department.
Further, a liquid outlet one-way valve is arranged on the liquid outlet pipe.
Has the advantages that: by arranging the valve, the phenomenon that external moisture or other pollutants enter the disinfection bag when the skin preparation knife is not used can be avoided.
Furthermore, a liquid guide groove is formed in the top surface of the mounting seat along the length direction of the lower pressing plate, and the liquid outlet pipe is communicated with the liquid guide groove.
Has the advantages that: the disinfectant discharged from the liquid outlet pipe firstly enters the liquid guide groove, slowly flows to the space between the comb teeth through the liquid guide groove, and then flows to the skin of a patient, so that the skin preparation part of the patient is disinfected.
