Medical closed negative-pressure invasive operation cabin

Abstract

The invention provides a medical closed negative-pressure invasive operation cabin. The medical closed negative-pressure invasive operation cabin comprises an airtight flexible thin film at a lower layer position and a foldable cover bin covering the thin film in a sealed mode, wherein the cover bin can be composed of five independent plates; and a transparent adhesive tape is respectively attached to the inner sides and the outer sides of the independent plates in advance. The medical closed negative-pressure invasive operation cabin provided by the invention is folded during packaging, is small in size, and can be rapidly assembled to form an operation space when in use; an opening for exposing a surgical wound surface in a transparent sealed operation cabin is arranged on the flexible thin film, and a circle of an adhesive tape close to the edge of the opening is arranged on the lower surface of the flexible thin film; two operation openings with the same height are correspondinglyarranged at the left side and the right side of the transparent sealed operation cabin; and the transparent sealed operation cabin is provided with an air inlet, an air outlet and a liquid inlet. According to the invention, a closed surgical operation space can be rapidly constructed in a simple clinical scene; pollution of an aerosol, respiratory tract secretions, blood and the like is effectively isolated; meanwhile, through a foldable desing, the medical closed negative-pressure invasive operation cabin can be rapidly transported and started during epidemic outbreak in emergency.

Description

technical field [0001] The invention relates to a medical protective appliance, in particular to a medical closed negative pressure invasive operation cabin. Background technique [0002] In surgical scenarios with high exposure risk (such as tracheotomy for patients with novel coronavirus pneumonia, chest surgery for patients with pulmonary tuberculosis, etc.), surgical operations will bring risks of aerosol exposure or blood contamination. This situation brings huge challenges to the safety protection of surgical operations. Even if there are sufficient safety protection facilities, the operator needs to wear protective glasses or positive pressure protective masks, which will have a significant impact on the surgical field of view. In grass-roots hospitals, under the condition of insufficient biosafety protection, patients are likely to lose the opportunity to undergo surgery under protected conditions; and when emergency surgery has to be performed, medical staff face a ...

Problems solved by technology

[0008] Publication No. CN 2652372Y discloses the protective isolation tent, which adopts a film tent to place the whole body of the patient in it, but the construction etc. are relatively complicated; the disclosed respiratory droplet spreading protection device of Publication No. CN 2621625Y adopts a A design similar to an umbrella, similar to the effect of a range hood, connecting negative pressure above the patient to suck away the pollutants, but the bottom is still open; Publication No. CN 209899593 U discloses a body fluid shield, which is A structure similar to a hexagonal umbrella is adopted to protect the operating area (such as hip replacement surgery) and reduce splash pollution; but the design is still an open structure; the closed tracheotomy disclosed by the publication number CN 2659352Y The device adopts a small transparent cover limited to the patient's larynx, and the intubation device is inserted vertically from the upper opening, which is not conducive to the operation and complicated situations; The antifouling cover, and the similar anti-sputum splashing protective cover after tracheotomy (public number is CN 206587252 U) adopt transparent cover, have hole design or band tube liquid collection, all are used as postoperative antifouling effect, Not suitable for intraoperative use

[0009] The protective cover of the above patent is not suitable for high-risk operations such as tracheal insertion surgery for patients with new coronavirus pneumonia because it does not cause a local negative pressure environment

In addition, due to the large size of the current protective cover, it is not easy to transport and store in a centralized manner. When a large-scale epidemic occurs, it is difficult to quickly transport it to the epidemic area
