Description

Technical Field

[0001] The invention relates to medical protective equipment, and in particular to a medical closed negative pressure invasive operation cabin. Background Art

[0002] In surgical scenarios with high exposure risks (such as tracheotomy, chest surgery for tuberculosis patients, etc.), surgical operations will bring the risk of aerosol exposure or blood contamination. This situation poses a huge challenge to the safety protection of surgical operations. Even if there are sufficient safety protection facilities, the need for operators to wear protective goggles or positive pressure protective masks will also have a significant impact on the surgical field of view. In grassroots hospitals, if biosafety protection conditions are insufficient, patients are likely to lose the opportunity to undergo surgery under protected conditions; and when emergency surgery has to be performed, medical staff face huge risks of infection.

[0003] Tracheotomy is an emergency measure for treating critically ill patients with breathing difficulties, hypoxia, etc. When the trachea is cut and the airway is inserted, tracheal irritation occurs, which can easily cause reflex coughing, causing the spray-like leakage of respiratory secretions and blood, and generating aerosols containing potential pathogens, which pose a great risk of infection to medical staff operating at close range. At present, the main approach to dealing with this type of invasive surgical infection risk in clinical practice is to strengthen the protection of medical staff and the isolation of the surgical operation space (including patients and medical staff). The following types of protective measures are mainly adopted:

[0004] 1) Protect medical staff by using N95 masks, protective clothing, protective goggles, positive pressure protective masks, etc.;

[0005] 2) Regarding the isolation of the surgical operation space, medical staff performed surgical operations on patients in negative pressure wards;

[0006] 3) In the process of treating highly contagious patients, it is necessary to combine the above two measures, including the use of negative pressure wards, N95 masks, protective clothing, protective goggles / positive pressure protective masks, etc., to provide all-round protection for medical staff.

[0007] At present, some existing technologies adopt isolation covers for protection. Here are some typical existing technologies for illustration:

[0008] The protective isolation tent disclosed in publication number CN 2652372Y adopts a thin film tent cover to place the whole body of the patient inside, but the construction is relatively complicated; the respiratory droplet dispersion protection device disclosed in publication number CN 2621625Y adopts a design similar to an umbrella cover, which is similar to the function of a range hood, and is connected to negative pressure above the patient to suck away pollutants, but the bottom is still open; the body fluid protection cover disclosed in publication number CN 209899593U adopts a structure similar to a hexagonal umbrella to protect the surgical area (such as hip replacement surgery) and reduce splash pollution; but the design is still an open structure; the closed tracheotomy device disclosed in publication number CN 2659352Y adopts a small transparent cover limited to the patient's throat, and the intubation device is inserted vertically from the upper opening, which is not conducive to surgical operations and dealing with complex situations; publication number CN 209696010 U discloses a post-tracheotomy anti-fouling cover and a similar post-tracheotomy anti-sputum splashing protective cover (publication number CN 206587252U) which adopts a transparent cover with a hole design or a tube for collecting liquid, and is used for post-operative anti-fouling and is not suitable for intraoperative use.

[0009] The protective shields of the above patents are not suitable for high-risk operations such as tracheal insertion of highly infectious patients because they do not create a local negative pressure environment. In addition, since the current protective shields are large in size, difficult to transport and store in a centralized manner, it is difficult to quickly transport them to the epidemic area when a large-scale epidemic occurs. Summary of the invention

[0010] The present invention establishes an effective closed surgical operation space through a negative pressure cabin. The anti-splash and anti-fog design ensures a clear surgical field of view. By providing an effective safety protection tool for high-exposure risk incisions, the infection exposure risk during surgery and the safety protection requirements of surgeons are significantly reduced. In the case of limited clinical resources, it can provide surgeons with maximum safety protection, improve the operability of surgery, and reduce the risk of hospital infection. It is especially suitable for use in primary hospitals. The specific plan is as follows:

[0011] A medical closed negative pressure invasive operation cabin, comprising an airtight flexible film at the bottom layer and a foldable cover sealed on the film.

[0012] The foldable cover comprises a first rectangular hard transparent plate in the middle and a second rectangular hard transparent plate which is sealed and rotatably connected to at least two opposite sides of the first hard transparent plate. When only two opposite sides of the first hard transparent plate are provided with the second hard transparent plate, two rectangular hard transparent side plates are sealed and rotatably connected to both sides of the flexible film. The side edges of the second hard transparent plate and / or the transparent side plate are provided with adhesive tape. After the second hard transparent plate on the first hard transparent plate and / or the transparent side plate on the flexible film are folded upward or downward and the side edges are adhered with adhesive tape, a transparent sealed operation cabin which is inverted on the flexible film is formed.

[0013] An opening is provided on the flexible film to expose the surgical wound surface in the transparent sealed operation cabin, and a circle of adhesive tape close to the edge of the opening is provided on the lower surface of the flexible film;

[0014] Two operating openings with the same height are provided on the second hard transparent panels or transparent side panels on the left and right sides of the transparent sealed operating cabin;

[0015] The side wall of the transparent sealed operating cabin is provided with several interfaces including an air inlet, an exhaust port, a liquid inlet and a liquid discharge port. The air inlet is connected to the delivery pipeline, the exhaust port is connected to the negative pressure device or the disinfection device, and the liquid discharge port is arranged at the bottom of the transparent sealed operating cabin.

[0016] Furthermore, the first hard transparent plate, the second hard transparent plate, and the transparent side plate are transparent plates made of acrylic material.

[0017] Furthermore, an arched notch that fits the contour of the neck is provided on the lower side of the second hard transparent plate on the front side of the transparent sealed operating cabin, a flexible sealing member extending to the outside of the operating cabin and fitting the contour of the neck is provided on the outside of the arched notch, and an adhesive tape is provided on the edge of the sealing member;

[0018] The flexible sealing element is soft rubber or silicone.

[0019] Furthermore, the height of the transparent sealed operating cabin is at least 45 centimeters.

[0020] Furthermore, gloves and sleeves are provided at the operation opening on the inner side of the second hard transparent plate, one end of the sleeve is connected to the glove, and the other end is sealed and connected to the second hard transparent plate at the edge of the operation opening.

[0021] Furthermore, the opening is a V-shaped or U-shaped opening, and the width of the front end of the opening is equivalent to the width of the arched notch.

[0022] Furthermore, the flexible film is a rubber pad.

[0023] Furthermore, a self-adhesive soft film for sealing and fixing the inlet and outlet pipelines is provided at the interface of the outer side wall of the transparent sealed operation cabin.

[0024] The enclosed negative pressure invasive operation cabin of the present invention adopts a foldable design, which can be quickly assembled when in use to form a surgical operation space, which is convenient for rapid transportation and activation in the event of an outbreak. The present invention constructs a relatively closed space between the patient and the medical staff through methods such as a plastic film layer with a lower sealing design, and collects the pollution sources generated during the operation, such as aerosols, respiratory secretions, and blood pollution, through negative pressure, thereby reducing the risk of infection to medical staff. In addition, the present invention combines functions such as negative pressure, air inlet, flushing, and waste liquid collection. Although the structure is simple, it is fully functional.

The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0033] The present invention provides a medical closed negative pressure invasive operation cabin, such as Figure 1 As shown, the medical closed negative pressure invasive operation cabin includes an airtight flexible film 20 at the bottom layer and a foldable cover 10 sealed on the film 20, the foldable cover 10 includes a middle rectangular first hard transparent plate 11 and a rectangular second hard transparent plate 12 sealed and rotatably connected to at least two opposite sides of the first hard transparent plate 11, and when the first hard transparent plate 11 is only provided with the second hard transparent plate 12 on two opposite sides, two rectangular hard transparent side panels 21 are sealed and rotatably connected on both sides of the flexible film 20. The side edges of the second hard transparent plate 12 and / or the transparent side panels 21 are provided with tape, and after the second hard transparent plate 12 on the first hard transparent plate 11 and / or the transparent side panels 21 on the flexible film 20 are folded upward or downward and the sides are glued with tape, a transparent sealed operation cabin inverted on the flexible film 20 is formed. Refer to Figure 2 As shown in FIG. 1 , the foldable cover 10 of one embodiment of the present invention is shown. A second hard transparent plate 12 is rotatably arranged on the four sides of the first hard transparent plate 11. When in use, the second hard transparent plate 12 is folded down at the same time to form the cover 10, and then it is turned upside down on the film 20. Figure 3-4 As shown, the foldable cover 10 consists of two parts. Figure 3 The first part is composed of a first rectangular hard transparent plate 11 in the middle and two second hard transparent plates 12 on the front and rear sides. Figure 4 The second part has two hard transparent side panels 21 on the upper surface of the film 20. During installation, we first fold down the second hard transparent panels 12 on both sides of the first hard transparent panel 11 and set them on the film 20. Then, we fold up the two hard transparent side panels 21 on the film 20 and combine them with the first part to form a closed negative pressure invasive operation cabin. It should be noted that strong adhesive tape is reserved at the edges and corresponding positions of the second hard transparent panel 12 and the transparent side panels 21 to ensure that the assembled operation cabin is well sealed. At the same time, after assembly, we can also use adhesive tape to strengthen the seal at the joint edge on the outside of the operation cabin.

[0034] An opening 22 is provided on the flexible film 20 to expose the surgical wound surface in the transparent sealed operation cabin, and a circle of adhesive tape (not shown) is provided on the lower surface of the flexible film 20 near the edge of the opening. Two operating ports 15 with the same height are provided on the second hard transparent plate 12 on the left and right sides of the transparent sealed operation cabin or on the transparent side plate 21; the side wall of the transparent sealed operation cabin is provided with several interfaces including an air inlet 16, an exhaust port 17, a liquid inlet 18 and a liquid discharge port 19, the air inlet 16 is connected to the delivery pipeline, the exhaust port 17 is connected to the negative pressure device or the disinfection device, and the liquid discharge port 19 is arranged at the bottom of the transparent sealed operation cabin and connected to the medical waste liquid collection pipeline. In order to meet the needs of various surgeries, in addition to the above-mentioned air inlet 16, exhaust port 17, liquid inlet 18 and liquid discharge port 19, we also provide a plurality of openable reserved interfaces on the side wall of the transparent sealed operation cabin so that we can connect more surgical pipelines. In addition to the sealing plug, the interface is connected to the outer side of the interface with two symmetrically arranged self-adhesive soft films to provide additional sealing.

[0035] When in use, we lay the flexible film 20 on the patient's body surface and the opening 22 of the flexible film 20 exposes the surgical wound surface, then we cover the first hard transparent plate 11 together with the second hard transparent plate 12 on the film 20 and ensure sealing, and the arched notch 13 of the second hard transparent plate 12 is stuck on the outer skin of the neck to ensure sealing, forming a negative pressure invasive operation cabin surrounding the wound surface, and after connecting the corresponding air intake, exhaust, liquid intake and discharge pipelines, the doctor puts his hand into the operation cabin to perform the operation. After the operation, the negative pressure cabin can be sprayed with alcohol for disinfection through the air inlet, and then the negative pressure exhaust (connected to the disinfection device) is connected.

[0036] On the one hand, the present invention can be applied to the isolation of the cervical surgical site, and on the other hand, it can also be applied to the isolation of the abdominal surgical site. It should be noted that when the present invention is applied to the cervical surgical site, an arched notch 13 that fits the neck contour needs to be provided on the lower side of the second hard transparent plate 12a on the front side of the transparent sealed operating cabin, and a flexible seal 14 that extends to the outside of the operating cabin and fits the neck contour is provided on the outside of the arched notch 13, and an adhesive strip is provided on the edge of the seal to fit the chin and neck below the patient's mouth. In an optional embodiment, the flexible seal 14 is soft rubber or silicone, which can better fit the patient's neck contour, avoid excessive gaps that are not conducive to the formation of negative pressure, and also reduce the discomfort caused to the patient. When the present invention is applied to the abdominal surgical site, the opening 22 of the flexible film 20 can be set in the middle position, such as Figure 8 .

[0037] In order to ensure cleanliness and hygiene, this operation cabin isolation device is independently packaged and sterilized in advance.

[0038] In an optional embodiment, the first hard transparent plate 11, the second hard transparent plate 12, and the transparent side plate 21 are transparent plates made of acrylic material, which are low in cost, easy to clean, and not easy to break, ensuring transportation safety. Optionally, the first hard transparent plate 11 and the second hard transparent plate 12 are connected by a strip of rubber to ensure that the second hard transparent plate 12 can be folded up and down.

[0039] In an optional embodiment, the height of the transparent sealed operating cabin is at least 45 cm to ensure that the doctor has an adequate field of vision.

[0040] In an optional embodiment, a glove and a sleeve are provided at the operation port 15 inside the second hard transparent plate 12 , one end of the sleeve is connected to the glove, and the other end is sealed to the second hard transparent plate 12 at the edge of the operation port 15 .
