Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and more specifically, to a splash-proof protective cover for the ear, nose, throat and neck. Background Technology
[0002] It is known that during treatment of the ear, nose, throat and neck, patients often experience nasal bleeding, pharyngeal fistula and other splashes of contaminants. Some patients undergoing tracheotomy and dressing changes may also experience splashes of blood, saliva, sputum, refluxed material, droplets and aerosols. Because these splashes can easily carry pathogens, they pose a significant safety hazard.
[0003] Most existing splash guards completely cover the head. For example, the "DIY Splash Guard" designed to prevent medical staff from directly contacting splashes generated by patients during dressing changes, and to prevent splashes from reaching the walls, floor, and air of the dressing room, thus preventing cross-infection of other patients.
[0004] Some products only provide local protection. For example, a Chinese invention patent application number 202010227538.1 discloses an oral treatment anti-splash protective shield, which prevents the generation of splashes by forming a sealed space outside the oral cavity, thus eliminating the spread of viruses caused by splashes.
[0005] However, in actual use, the aforementioned head-covering products reduce the operating space, making dressing changes inconvenient. Furthermore, the aforementioned protective shields designed for the outside of the mouth lack splash protection for the neck. Consequently, there is a lack of appropriate protective shields for splashing situations that occur during dressing changes for patients with nasal bleeding, pharyngeal fistula, or tracheotomy. Therefore, in order to protect patients' ears, nose, and throat from splashing, a splash-proof protective shield for the ears, nose, throat, and neck is proposed as a further improvement. Utility Model Content
[0006] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a splash-proof protective cover for the ear, nose, throat and neck, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a splash-proof protective cover for the ear, nose, throat and neck, comprising a protective cover body, both sides of the protective cover body being configured as side protective surfaces, two parallel sides of the protective cover body adjacent to both side protective surfaces being configured as head protective surfaces and neck protective surfaces respectively, and the surfaces of the protective cover body adjacent to the side protective surfaces, head protective surfaces and neck protective surfaces respectively being configured as main protective surfaces;
[0008] The side protective surface, head protective surface, and neck protective surface are respectively provided with a first slot for operating the dressing change instrument, a second slot for placing it on the head, and a third slot for placing it on the neck.
[0009] The side protection surface, head protection surface, and neck protection surface are all provided with round holes for installing suction devices.
[0010] Furthermore, the shapes of the first, second, and third bayonets are all set to semi-elliptical.
[0011] Furthermore, the protective cover body is fixedly installed with clips for installing light strips at the four corners near the main protective surface.
[0012] Furthermore, connectors for connecting the chair are fixedly installed at the four corners of the protective cover body away from the main protective surface.
[0013] Furthermore, the length of the protective cover body used to cover the width of the patient's face, the length of the operator's hand, and the operating space for the dressing change instruments is set as 'a'; then a ≥ 30cm;
[0014] The length of the protective cover body used to wrap the patient from the eye socket to the collarbone is set as b; then 20cm≤b≤30cm;
[0015] The protective cover body is used to cover the distance from the patient's occiput to the tip of the nose and the length of the operating space for the dressing change instrument, which is set as c; then c≥25cm.
[0016] Furthermore, the material of the protective cover body is set to a transparent plastic material.
[0017] The technical effects and advantages of this utility model are as follows:
[0018] Compared with existing technologies, by setting up a protective cover body, utilizing a first slot for operating dressing change instruments, a second slot for placement on the head, and a third slot for placement on the neck, the protective cover body achieves a high degree of human body fit. This protective cover body can prevent medical personnel from directly contacting splashes generated by patients during dressing changes, and prevent splashes from reaching the walls, floor, and air of the dressing room, thus preventing cross-infection of other patients. In the event of splashing, a suction device installed in the round hole can quickly handle the situation. The use of clips to fix the light strip ensures sufficient light for medical personnel during operation, preventing serious accidents. Attached Figure Description
