Description
Technical Field
The utility model relates to a cotton pad, especially a fixed cotton pad of knee joint replacement postoperative anti-drop pressurization.
Background
The prior orthopedic medical cotton pad used for knee joint replacement in clinic has the following defects in the clinical use process:
1. the whole medical cotton pad only has the function of covering the operation opening (wound) and does not have the fixing function, and the medical cotton pad needs to be fixed by an adhesive tape additionally, so that the material consumption is increased;
2. for the knee joint replacement (total knee joint replacement/knee unicondylar replacement), because the operation incision is large, a cotton pad with a large specification is required to be used for pressurizing and covering (the purpose is to pressurize and reduce bleeding, and the cotton pad timely sucks away wound bleeding to prevent bacteria and the like from breeding and causing infection, and ensure that the wound is isolated from the outside to prevent infection), but the existing cotton pad does not have the pressurizing and fixing function, so the bleeding amount in the operation mouth after the operation is increased, meanwhile, because the cotton pad is easy to fall off (a patient needs to walk on the ground for functional exercise after 2 hours after the knee joint replacement, the fixing effect of an external adhesive tape is very little when the knee joint is bent and stretched, the cotton pad is very easy to fall off), the risk of wound infection is greatly increased, and once infection occurs after the knee joint replacement, the risk is fatal. In addition, after the cotton pad falls off, the patient no longer dares to carry out abundant function exercise, and this is extremely unfavorable to the recovery of postoperative knee joint function, probably induces knee joint stiffness etc. greatly influences the operation curative effect, reduces patient's satisfaction.
SUMMERY OF THE UTILITY MODEL
Based on this, the utility model aims at overcoming above-mentioned prior art's weak point and providing a fixed cotton pad of knee joint replacement postoperative anti-drop pressurization. The fixing cotton pad can be used for pressurizing, fixing and protecting the wound after knee joint replacement, thereby reducing the bleeding amount of the wound after the operation, reducing the infection incidence rate of the wound after the operation, ensuring the safety function exercise of the patient after the operation to recover the knee joint function as early as possible, ensuring the curative effect of the operation and improving the satisfaction degree of the patient.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a fixed cotton pad of knee joint replacement postoperative anti-drop pressurization, the fixed cotton pad of pressurization is including three kinds of cotton pads that the combination was used, three kinds of cotton pads follow supreme down and do in proper order: a type A cotton pad, a type B cotton pad and a type C cotton pad;
the A-type cotton pad is a rectangular cotton pad with the length of 15cm and the width of 10cm, 3 adhesive tapes with the width of 1.5cm are arranged at each long edge of the A-type cotton pad, and the length of the adhesive tapes extending out along the long edge is 3 cm;
the B-type cotton pad is a rectangular cotton pad with the length of 25cm and the width of 20cm, 3 adhesive tapes with the width of 1.5cm are arranged at each wide edge of the B-type cotton pad, and the length of the adhesive tapes extending out along the wide edge is 3 cm;
the C-shaped cotton pad is a right-angle trapezoidal cotton pad with an upper bottom of 40cm and a lower bottom of 50cm, 3 adhesive tapes with the width of 5cm are arranged at the right-angle waist edge of the C-shaped cotton pad, and the length of the adhesive tapes extending out along the right-angle waist edge is 5 cm; the C-shaped cotton pad is characterized in that 3 adhesive tapes with the width of 5cm are arranged at the oblique waist edge of the C-shaped cotton pad, and the sum of the length of the adhesive tapes extending out along the oblique waist edge and the length of the cotton pad is the length of the lower bottom of the cotton pad.
At present, the conventional compression fixation is realized by using other adhesive tapes and bandages, but the adhesive tapes and the bandages can only be used for the fixation of the outermost layer, and the cotton pad (A, B) inside cannot be completely bound by the adhesive tapes or the bandages, because a space must be reserved around the cotton pad so as to completely suck out the oozed blood in the operation opening and finally adsorb the oozed blood to the cotton pad on the outer layer, thereby ensuring the normal drainage of the operation opening and preventing infection; however, if the cotton pad inside is not pressed and fixed at all, the two reasons are that: firstly, the pressurization can ensure the timely discharge of the oozing blood, the closing of the operation opening is good, no cavity gap is left under the skin, the healing is facilitated, and the two pressurization have better fixing function to prevent the cotton pad from falling off during the functional exercise. Therefore, the cotton pad in the utility model creatively adopts three different types of cotton pads to be combined for use, so that the combined cotton pad has the pressurizing and fixing functions, the pressurizing and hemostasis of the wound after operation can be ensured, and the bleeding is reduced; can ensure the patients to carry out routine functional exercise after the operation, reduce the interruption of functional exercise caused by the falling of cotton pads and the like, promote the early recovery of the affected knee, and reduce the complications of joint stiffness and the like.
Preferably, in the A-type cotton pad, the 3 tapes are respectively arranged at two end points and the middle position of the long edge of the A-type cotton pad; in the B-type cotton pad, the 3 tapes are respectively arranged at two end points and the middle position of the wide edge of the B-type cotton pad; in the C-shaped cotton pad, the rubberized fabric is respectively arranged at two end points and the middle position of the right-angle waist edge and the oblique waist edge of the C-shaped cotton pad.
The utility model discloses the quantity of well adhesive tape and the setting of position can play good pressurization fixed action, are unlikely to again to seal around leading to the cotton pad of A type because of the adhesive tape is too much, lead to the oozing blood outflow not smooth, and then arouse infection etc..
Preferably, the adhesive is a paper adhesive.
Preferably, the cotton pad of A type, the cotton pad of B type, the cotton pad of C type all include two-layer absorbent gauze and one deck absorbent cotton, the absorbent cotton is located between two-layer absorbent gauze.
Preferably, the fixed cotton pad of pressurization is including the cotton pad of four layers of combination use, four layers of cotton pads are from supreme down and are in proper order: a type cotton pad, B type cotton pad, C type cotton pad.
Preferably, the thickness of the absorbent cotton is 2-3 cm. The absorbent cotton in the cotton pad mainly has the effects of adsorbing blood exuded from the surgical port and ensuring the relative dryness of the surgical port, thereby reducing the infection occurrence probability and promoting the healing of the surgical port, so the absorbent cotton needs to have certain thickness so as to ensure the complete absorption of the blood exuded from the surgical port.
Preferably, sterile gauze is arranged below the A-type cotton pad.
Compared with the prior art, the beneficial effects of the utility model are that:
(1) the cotton pad has the function of pressurizing and fixing, so that the pressurizing and hemostasis of the wound after the operation can be ensured, and the bleeding is reduced;
(2) the fixation is good, the conventional functional exercise of the patient after the operation can be ensured, the functional exercise interruption caused by the falling of the cotton pad and the like is reduced, the early recovery of the affected knee is promoted, and the complications such as the joint stiffness are reduced;
(3) the cleanness and relatively sterile environment of the operation opening are kept, and the failure of the knee joint replacement operation caused by the operation opening infection is avoided (once the knee joint replacement operation is infected by the joint prosthesis, the consequence is very serious);
(4) from taking fixed function, reduce extra medical consumptive material, practice thrift the cost.
