Abstract
Description
Technical Field
[0001] This utility model relates to the field of tonsillectomy technology, and in particular to a sterile surgical drape that can be used in tonsillectomy under local anesthesia. Background Technology
[0002] Tonsillectomy under local anesthesia is a common ENT procedure primarily used to treat chronic tonsillitis or other tonsil diseases. During the procedure, the patient remains conscious throughout, but local anesthetic drugs are used to numb the surgical area to reduce pain and discomfort. Tonsillectomy is a clean-contamination procedure, requiring strict pre-operative sterilization. Before surgery, the patient's skin is cleaned and disinfected to reduce the number of bacteria at the surgical site and lower the risk of infection. Furthermore, the surgical area is rigorously sterilized, and surgical instruments, dressings, and the operating room environment must all meet sterile standards.
[0003] During tonsillectomy under local anesthesia, blood and oral secretions are produced. To prevent aspiration, patients are always positioned sitting up during the procedure. Currently, there is no one-piece sterile surgical drape for tonsillectomy under local anesthesia. Instead, the surgeon cuts a disposable drape to size according to the patient's condition and places it on the surgical site. During the procedure, improper cutting or fixation can cause the drape to shift, exposing other skin areas or causing leakage of saliva and blood, resulting in contamination. Therefore, a sterile surgical drape that can be used in tonsillectomy under local anesthesia is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a sterile surgical drape that can be used in tonsillectomy under local anesthesia, aiming to improve the problem that the use of disposable drapes in the prior art is cumbersome and prone to contamination.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a surgical sterile drape applicable in tonsillectomy under local anesthesia, comprising a head sterile drape, a body sterile drape fixedly connected to the bottom of the head sterile drape, a square groove opened at the front of the head sterile drape, a transparent membrane fixedly connected to the front of the square groove, an opening groove opened at the lower front side of the head sterile drape, a waterproof pocket fixedly connected to the front of the head sterile drape, and a fixing member provided at the rear of the body sterile drape.
[0006] As a further description of the above technical solution:
[0007] The fastener includes an elastic cord, the end of which is fixedly connected to the rear of the sterile drape.
[0008] As a further description of the above technical solution:
[0009] The waterproof bag is made of thermoplastic polyurethane elastomer rubber.
[0010] As a further description of the above technical solution:
[0011] The transparent film is made of medical-grade polyurethane.
[0012] This utility model has the following beneficial effects:
[0013] 1. In this utility model, through the cooperation between the sterile drape, the opening groove, the waterproof pocket, the transparent membrane and its fixing components, the sterile drape is put on the patient during surgery and fixed by the fixing components, thereby reducing the risk of cross-infection and avoiding secondary contamination. The disposable drape does not need to be manually cut during use, thus improving work efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figure 1This utility model provides an embodiment of a surgical sterile drape applicable in tonsillectomy under local anesthesia. It includes a head sterile drape 1, with a body sterile drape 2 fixedly connected to the bottom of the head sterile drape 1. The head sterile drape 1 protects the patient's head, while the body sterile drape 2 covers the patient's body, thus protecting the patient's body parts and reducing the outflow of secretions or blood. The sterile drape is made of a new type of non-woven SMS material with three layers, which is lightweight, soft, and comfortable. It is sterilized with ethylene oxide before leaving the factory. Multiple models of sterile drapes can be produced to suit different patients. The sterile drape 1 is a single-use product, avoiding the risk of aging and loosening of fibers after repeated washing of traditional cloth drapes, which can easily lead to dust or seepage. A square groove is provided at the front of the head sterile drape 1, and a transparent film 6 is fixedly connected to the front of the groove. The transparent film 6 allows the patient to see clearly, thus reducing the risk of claustrophobia. In the event of closure, an opening groove 3 is provided on the lower front side of the head sterile drape 1. The opening groove 3 facilitates artificial respiration, and corresponding secretions can be drained through the opening groove 3. A waterproof pocket 4 is fixedly connected to the front of the head sterile drape 1. The waterproof pocket 4 can be pulled forward during use to collect secretions. A fixing member 5 is provided at the rear of the body sterile drape 2. The fixing member 5 can electrostatically fix the patient's neck. The fixing member 5 includes an elastic cord 501. The end of the elastic cord 501 is fixedly connected to the rear of the body sterile drape 2. The elastic cord 501 can be pulled open during use, and then the sterile drape is put on the patient. After being put on, the elasticity of the elastic cord 501 will fix the sterile drape. The waterproof pocket 4 is made of thermoplastic polyurethane elastomer rubber. Thermoplastic polyurethane elastomer rubber has a dense molecular structure and has extremely low water absorption and good waterproof barrier performance. During the surgery, patients may vomit secretions. The waterproof cover 4, made of thermoplastic polyurethane elastomer rubber, can reliably block these liquids and prevent them from seeping under the sterile drape, thereby avoiding contamination of the surgical area, the patient's clothing, and the bed. The transparent film 6 is made of medical-grade polyurethane, which can effectively prevent damage to the patient's eyes and surrounding skin, and has extremely high transparency with a light transmittance of over 90%, providing the patient with a clear field of vision.
[0019] Working principle: During tonsillectomy under local anesthesia, medical staff first remove the sterile drape, pull open the elastic cord 501 in the fixation piece 5, and put the sterile drape over the patient. The body sterile drape 2 covers the patient's body from the shoulders down, and the head sterile drape 1 covers the patient's head. After being put on, the elastic cord 501, with its own elasticity, fixes the sterile drape, ensuring it is stably worn on the patient and preventing displacement during the operation. Then, the waterproof bag 4 is pulled open. When the patient has secretions, they can be collected through the waterproof bag 4, thus preventing the secretions from flowing to other parts of the patient. The overall operation is relatively simple.
[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
