Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a medical wound suturing plaster.
Background
Skin wounds are the common linear wounds after surgery and are usually sutured with medical needles and threads. The suture method not only needs longer suture time, improves the operation book sword and increases the operation risk of the patient, but also can leave obvious scars after the wound is healed by adopting the suture method, can cause secondary wound in the process of removing the suture and increases the pain of the patient.
In order to solve the above problems, there are many suturing devices for suturing a wound in the prior art, which are adhesively attached to both sides of the wound, and which close the wound by pulling a locking strip on both sides of the wound, so as to avoid the scar left by using a needle and thread suturing method. For example, patent application No. CN201420347195.2 discloses a wound suturing device, which belongs to the field of wound suturing medical devices, and the wound suturing device comprises a first soft main board and a second soft main board identical to the first soft main board, wherein an adhesive tape is arranged on the lower surface of the first soft main board, and one or more locking tapes are arranged on the upper surface of the first soft main board; and the lower surface of the second soft main board is provided with an adhesive tape, and the upper surface of the second soft main board is connected with the lock belt thread gluing.
This wound suturing device pastes first soft mainboard and the soft mainboard of second in the both sides of wound when using, pull the locking band through one side to the wound and make the wound closure, because skin has laxity and elasticity, follow the in-process to the soft mainboard pulling of second with first soft mainboard, the skin that is close to wound can pile up before the vertical side of first soft mainboard, make first soft mainboard and locking band all contradict on this skin, the great pulling force that produces when pulling can lead to first soft mainboard to act on the supporting and touching force on the skin great, thereby cause the damage of near wound skin, patient's postoperative misery has been increased, patient's operation recovery time has been prolonged.
Disclosure of Invention
The technical problem to be solved by the invention is as follows: overcomes the defects of the prior art, and provides the medical wound suture plaster which has simple structure and convenient use and can reduce the skin injury near the wound.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a medical wound is sewed up and is pasted, is including the sewing mechanism who locates the wound both sides, and the sewing mechanism who is located the wound both sides connects through the locking device that a plurality of parallel intervals set up, and sewing mechanism includes from last base cloth layer, adhesive layer and the pad pasting layer that connects gradually extremely down, is equipped with the foam pad between base cloth layer and the adhesive layer, and the foam pad is close to one side of wound or its one side that is close to the wound with the base cloth layer and is connected with fold portion, and fold portion is transversely connected in succession side by a plurality of folds and constitutes.
The setting of fold portion can improve this buffer power of sewing up subsides, when sewing up the wound through dragging locking device, locate base cloth layer and/or foam pad and be close to the fold portion of one side of wound and have the elastic cushioning effect, the direction of the buffer force that this elastic cushioning effect produced and base cloth layer, foam pad extrusion skin's opposite direction, the extrusion force that base cloth and foam pad acted on near skin of wound has been reduced, thereby base cloth and foam pad have been reduced to near skin's of wound damage, the cross infection of wound department is taken in the damage of having avoided near skin of wound, patient's recovered time has been shortened, the treatment effeciency of sewing up of wound has been improved.
Further, the height of the foam pad and the height of the base cloth layer are equal to the height of the wrinkle part, the height of the wrinkle part is 1.5-3mm, and the width of the wrinkle part is 5-7 mm.
The heights of the foam pad and the base cloth layer are equal to the height of the fold part, so that the sewing paste is stressed more uniformly when the locking device is pulled, and the tearing phenomenon during pulling is avoided; when the height of the fold part is less than 1.5mm, the height of the foam pad is also less than 1.5mm, when the locking device is pulled, the skin near the wound is in more contact with the base cloth layer, and the base cloth layer is easy to cause skin damage when being abutted against the skin due to the fact that the base belt material in the base cloth layer is hard; when the height is greater than 3mm, the hollow area inside the fold part is larger, and when the fold part is pulled by the locking device, the fold part is easy to bend and incline, so that the suture of the wound is influenced.
When the width of the fold part is less than 5mm, the buffer force generated by the fold part when the wound is sutured is small, and the buffer protection effect on the skin around the wound is not enough; when the width is larger than 7mm, the elasticity of the fold part is larger, and when the locking device is pulled, the resultant force in the direction of the wound is smaller (namely, the traction force in the direction of the wound is smaller), so that the wound suturing time is prolonged, and the suturing efficiency is reduced.
Further, the inner side of the lower surface of the adhesive layer is coated with the anesthetic, and the outer side of the lower surface of the adhesive layer is coated with the antibacterial coating.
The anesthetic can reduce the pain of a patient when the wound is sutured, the antibacterial coating has an antibacterial effect, the infection of the wound periphery to the wound can be reduced, the phenomenon of secondary infection is avoided, and the wound healing is promoted.
Further, the base cloth layer comprises an upper non-woven fabric layer and a lower non-woven fabric layer arranged below the upper non-woven fabric layer.
Further, locking device includes hasp, locking bar and baseband, the baseband is located respectively between the upper non-woven fabrics and the lower floor non-woven fabrics of wound both sides, the interval is provided with a plurality of ratchets on the locking bar, the through-hole has been seted up on the hasp, be equipped with in the through-hole with ratchet matched with pawl.
Furthermore, the bottom end of the lock catch is connected with the base band positioned on one side of the wound, the top end of the lock catch extends out of the upper non-woven fabric layer, one end of the lock bar is connected with the base band positioned on the other side of the wound, and the other end of the lock bar penetrates through the through hole to be locked and sews the wound below the two sewing mechanisms.
Further, the bottom of hasp is located two basebands that are located the wound both sides, and outside its top stretched out the upper non-woven fabrics that is located the wound both sides, the one end of locking strip with the hasp is connected, and its other end each other passes the hasp locking of offside and sews up the wound of two sewing up mechanisms below.
Further, the cross section of the folds is any one of a V shape, a zigzag shape and a parabolic shape.
Further, the adhesive layer is made of polyester fabric, polyamide or bandage cloth with elasticity.
Further, the base cloth layer, the adhesive layer and the film pasting layer are sequentially adhered through gluing.
The medical wound suture plaster has the beneficial effects that: according to the invention, the fold part is arranged on one side of the foam pad close to the wound or one side of the foam pad close to the wound and the base fabric layer, and the fold part can generate a buffer force opposite to the tensile force of the locking device when the skin on two sides of the wound is sutured, so that the interference force of the base fabric layer to the skin near the wound when the suture paste is sutured to the wound is reduced, the damage of the suture paste to the skin is reduced, the phenomenon that the wound is secondarily infected due to the damage of the skin near the wound is avoided, the pain of a patient is reduced, and the suture treatment efficiency of the wound is improved.
