Description

A disposable negative pressure isolation cover for tracheal intubation

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a disposable negative pressure isolation cover for endotracheal intubation.

Background Art

Respiratory viruses are a type of virus that invades through the respiratory tract as the main route and can proliferate in large numbers in the epithelial cells of the respiratory mucosa, thereby causing local respiratory infections or tracheal viruses in tissues outside the respiratory tract. Common respiratory virus types include Orthomyxoviridae, Paramyxoviridae, etc.

When performing tracheal intubation, airway operations, and anesthesia management on patients infected with respiratory viruses, doctors face the patient's respiratory tract at close range. The patient's secretions, blood, or droplets or aerosols produced are a great threat to virus transmission to doctors and other personnel in the operating room. Or when patients who are not infected with respiratory viruses face other infected patients or medical staff in the operating room, they are very likely to be infected with respiratory viruses due to their respiratory exposure and perioperative immunosuppression, resulting in poor postoperative recovery.

At present, the protection of anesthesiologists for tracheal intubation basically focuses on the secondary protection of the doctors themselves or the ordinary negative pressure isolation hoods used by patients using conventional tracheal intubation methods, including operation holes, oxygen supply channels, and negative pressure suction holes. However, for patients with difficult airways who need to use special intubation tools such as visual contraceptives, light sticks, and fiberoptic bronchoscopes, and patients who need to use fiberoptic bronchoscopes for thoracic surgery or intraoperative airway complications, the use of such isolation hoods is still limited. Moreover, during airway operations on such patients, the risk of choking and coughing, resulting in droplet and aerosol diffusion, is higher.

Therefore, a disposable negative pressure isolation cover for endotracheal intubation is proposed to reduce respiratory virus infection.

A disposable negative pressure isolation cover for tracheal intubation as shown in Figures 1 to 4 comprises: an isolation cover body 1 for covering the patient's head, an isolation bottom pad 2 for padding the patient's head, and a support frame 10 for supporting the isolation cover body 1. The isolation cover body 1 and the isolation bottom pad 2 are detachably sealed and connected, and the outer edge of the isolation cover body 1 is provided with a pipe sleeve 11 matching the support frame 10, and the support frame 10 is sleeved on the outside of the isolation cover body 1 through the pipe sleeve 11. The isolation cover body 1 includes a transparent film isolation cover, which is made of a transparent film to facilitate the intubation operation of medical staff. In addition, since the transparent film is cheap and easy to obtain, it can be discarded after use to avoid cross infection. The isolation bottom pad 2 includes a melt-blown cloth bottom pad, which is made of melt-blown cloth, has low cost, good isolation effect, can be discarded after use, and avoid cross infection. The edges of the isolation cover body 1 and the isolation bottom pad 2 are connected by double-sided adhesive bonding, which is low in cost, simple to operate, and can be adjusted according to the patient's head and neck, flexible to use, and high in efficiency. The support frame 10 supports the isolation cover body 1 outside the isolation cover body 1 through the pipe sleeve 11, forming an operating space sufficient to accommodate the patient's head and facilitate intubation. The support frame 10 is arranged outside the isolation cover body 1 to reduce the contamination of the inside of the isolation cover during the installation process. The support frame 10 is composed of a plurality of detachably connected support rods. The shape and material of the support frame 10 are not limited, which facilitates the installation and disassembly of the support frame 10. Preferably, the support frame 10 is a lightweight plastic frame that can be discarded after use to avoid cross infection.

The isolation cover body 1 is provided with a head placement area 12, and two head end operation holes 3 are provided on the top side of the isolation cover body 1 where the head placement area 12 is provided. An auxiliary operation hole 4 is provided on the left side of the isolation cover body 1 where the head placement area 12 is provided, so that an assistant can put his hand into the isolation cover for auxiliary operation. The two head end operation holes 3 and the inner sides of the auxiliary operation holes 4 are both provided with rubber gloves that are tightly connected, so that the attending doctor can put his hand into the isolation cover for operation; the top surface of the isolation cover body 1 where the head placement area 12 is provided with a special intubation tool insertion hole 5, so that special intubation tools (visual conduit, light rod, fiber bronchoscope, etc.) can be inserted; the right side of the isolation cover body 1 where the head placement area 12 is provided with a negative pressure suction device insertion hole 6 and a breathing tube insertion hole 7; the outer sides of the special intubation tool insertion hole 5, the negative pressure suction device insertion hole 6 and the breathing tube insertion hole 7 are all connected with a protective sealing sleeve 8, and a sealing device 9 is provided at the top opening of the protective sealing sleeve 8. The protective sealing sleeve 8 is in the shape of a long tube, which can be inserted into special intubation tools and pipelines. It can play a sealing role by fixing the top edge of the long tube-shaped protective sealing sleeve 8 on the special intubation tools and pipelines to prevent the aerosol or droplets exhaled by the patient from leaking out from the special intubation tools and pipeline extensions. The material of the protective sealing sleeve 8 is not limited, as long as it can play an isolation effect. Preferably, it is made of plastic film and/or meltblown cloth, which is cheap and easy to obtain, has good flexibility and is easy to seal. The length of the protective sealing sleeve 8 connected to the through hole 5 for the special intubation tool is not less than 0.8 meters; the length of the protective sealing sleeve 8 connected to the through hole 6 for the negative pressure aspirator and the through hole 7 for the breathing tube is not less than 2 meters, ensuring the complete sealing of special intubation tools such as visual conni, light stick, fiberoptic bronchoscope, and suction and breathing tubes.

Working principle: The patient lies on his back and places his head on the melt-blown cloth isolation base pad 2 through the head placement area 12 provided on the isolation cover body 1. The disposable oropharyngeal airway, disposable nasopharyngeal airway, visual laryngoscope, disposable visual laryngoscope blade, paraffin oil, oxygen mask, endotracheal tube, suction tube and other tools required for intubation are placed on the melt-blown cloth isolation base pad 2. The oxygen circuit is placed in the isolation cover body 1 through the extended protective sealing sleeve 8 and the breathing tube through the breathing tube insertion hole 7 to supply oxygen to the patient, and the extended protective sealing sleeve is placed. The double-sided adhesive tape at the top opening edge of the seal 8 is fixed and sealed on the breathing tube, and the negative pressure suction tube is placed in the isolation cover body 1 through the through hole 6 of the negative pressure suction device through the extended protective seal sleeve 8, and the double-sided adhesive tape at the top opening edge of the extended protective seal sleeve 8 is fixed and sealed on the negative pressure suction device tube, and the support frame 10 is placed above the patient's head, and the isolation cover body 1 is covered on the support frame 10, and then the isolation cover body 1 and the edge of the melt-blown cloth isolation pad 2 are bonded and fixed with double-sided adhesive, so as to isolate the patient's head. At this time, the two head end operation holes 3 on the isolation cover body 1 are at the patient's head end, and the auxiliary operation hole 4 on the isolation cover body 1 is at the left end of the patient's head. Since these three channels are equipped with rubber gloves with closed connections, they are in a closed state through the sealing cover when not in use. When in use, the doctor opens the sealing cover, reaches into the isolation cover and wears rubber gloves to operate. The special intubation tool insertion hole 5 on the isolation cover body 1 is located above the patient's head. The special intubation tools such as fiberoptic bronchoscope, light stick, and visual conduit are inserted through the extended protective sealing sleeve 8 and the special intubation tool insertion hole 5. After the insertion is completed, the double-sided tape at the top opening edge of the extended protective sealing sleeve 8 is fixed and sealed on the special intubation tool to achieve the isolation effect. The anesthesiologist can operate the special intubation tool outside the isolation cover to complete the intubation operation. After the intubation is completed and the operation is over, the sealing device 9 is closed, and the double-sided tape at the edge of the isolation cover body 1 and the isolation bottom pad 2 is torn off, so that the contaminated special intubation tools, negative pressure suction pipelines, etc. can be completely sealed in the isolation cover body 1 and sent for disinfection to reduce virus transmission.
