Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to an isolation device for use in infectious diseases departments for preventing medical personnel from being infected. Background Art

[0002] An isolation stretcher is a medical device used to transport patients. Its main feature is that it has an isolation and protection function, which can reduce the spread of pathogens or harmful substances between the patient and the external environment during the transportation process, while also providing certain protection for patients and medical staff. For example, the negative pressure isolation inflatable stretcher for infectious patients proposed in patent publication number CN102100594B.

[0003] During use, existing isolation stretchers use isolation membranes to build an isolation barrier between patients and the outside air. However, the hospital environment is complex, and isolation stretchers will inevitably come into contact with various medical instruments, such as scissors, tweezers, syringes, etc. If these instruments are not placed properly, their sharp points can easily scratch the isolation membrane. Furthermore, during transportation, the stretcher may also collide or rub against surrounding objects, such as corners, metal frames of carts, railings of beds and other hard objects, which will also cause damage to the isolation membrane. Some damage is relatively small and difficult for medical staff to quickly detect and repair. Once the isolation membrane is damaged, when transporting patients, medical staff are very likely to come into contact with patient fluids leaked from the damaged area, such as blood, sputum, vomit, etc. In this way, medical staff are exposed to pathogens and the risk of infection is significantly increased.

After the detection component 15 is used to find the small damaged areas on the surface of the isolation cover 3, the disinfectant can be automatically sprayed onto the damaged areas to disinfect the damaged areas, thereby reducing the risk of infection for medical staff repairing the damaged areas and improving the safety performance of the stretcher 1.

[0041] A camera 45 is fixedly connected to the right side wall of the detection frame 152, and an operation display panel 46 is connected to the right side wall of the negative pressure generator 5. The camera 45 and the operation display panel 46 are electrically connected to facilitate medical staff to observe the patient's pupils and other vital signs.

[0042] Shock absorbers 47 are fixedly connected to the four corners of the lower side wall of the stretcher 1. The lower end of the shock absorber 47 is connected to a self-locking wheel 39, which reduces the vibration of the stretcher 1 when it moves.

[0043] The operating principle of the present invention is now explained as follows: the isolation seat 2 is fixed to the upper side wall of the stretcher 1 through the snap mechanism (the upper side wall of the stretcher 1 is provided with a female buckle, and the lower side wall of the isolation seat 2 is provided with a sub-buckle. By pressing the female buckle, the isolation seat 2 can be fixed to the upper surface of the stretcher 1), then the air outlet on the surface of the isolation seat 2 is connected to the air inlet of the negative pressure generator 5, and the air outlet of the air pump 14 is connected to the cross pipe 111, the liquid outlet pipe 41 connected to the liquid outlet end of the water pump 40 is connected to the sealing ring 381, and the return water pipe 42 is connected to the sealing ring 381, then pull the airtight zipper to open the isolation cover 3, let the patient lie on the isolation seat 2 with his head facing the direction of the negative pressure generator 5, and then close the isolation cover 3 through the airtight zipper, and then the medical staff sends an electrical signal to the PLC controller 8 through the operation display panel 46, and the PLC controller 8 will control The negative pressure generator 5 works and extracts the gas inside the isolation cover 3. When the air pressure inside the isolation cover 3 drops to the set threshold value (-20Pa), the external gas will enter the isolation cover 3 through the air inlet pipe 6 and the first pressure valve 7, so that the interior of the isolation cover 3 is maintained at the set negative pressure state. Then the infusion bottle 9 is placed in the placement cylinder 37, and the upper end of the infusion tube 10 is inserted into the infusion bottle 9, and then the lower end of the infusion tube 10 is passed through the jack on the surface of the isolation cover 3, and the needle at the lower end of the infusion tube 10 is inserted into the patient's body for infusion (assuming that the patient needs infusion). The isolation cover 3 is a transparent structure, which allows the doctor to see the patient's blood vessels. A plurality of operating gloves (not shown in the figure) are provided on the surface of the isolation cover 3. The medical staff inserts their hands into the operating gloves to perform infusion for the patient or conduct some examinations.

[0044] And when the needle at the lower end of the infusion tube 10 is inserted into the patient's blood vessel, the medical staff can send an electrical signal to the PLC controller 8 through the operation display panel 46. After receiving the electrical signal, the PLC controller 8 will control the water pump 40 to work. The water pump 40 will transport the liquid inside the water cylinder 44 to the sealing ring 381 through the liquid outlet pipe 41, thereby increasing the water pressure inside the sealing ring 381. The water pressure inside the sealing ring 381 will cause the rubber ring 382 to expand. The rubber ring 382 will expand in the direction close to the infusion tube 10 and contact the inner wall of the infusion tube 10. When the rubber ring 382 is After the ring 382 expands to a set range, the water pressure inside the sealing ring 381 will exceed the set threshold of the second pressure valve 43 and will flow back through the return pipe 42 to the water cylinder 44 for storage. The expanded rubber ring 382 is used to seal the gap between the infusion tube 10 and the isolation cover 3. When the stretcher 1 is used in winter, medical staff can control the heating element on the inner wall of the water cylinder 44 (the heating element is a heating plate or heating wire) to heat the liquid inside the water cylinder 44, thereby heating the liquid medicine inside the infusion tube 10 and preventing the low-temperature liquid medicine from irritating the patient's blood vessels.

[0045] When the patient lies down, the medical staff can control the linear motor 151 through the operation display panel 46. The linear motor 151 drives the detection frame 152 and the camera 45 to move forward together, so that the camera 45 moves to the patient's facial area. The patient's facial features are projected into the display area of ​​the operation display panel 46 through the camera 45, making it convenient for the medical staff to observe the patient's pupils and other vital signs at any time.

[0046] When the isolation cover 3 or the isolation seat 2 is damaged due to an accident, the external gas will enter the isolation cover 3 through the damaged part, so that the air pressure sensor detects that the negative pressure value inside the isolation cover 3 becomes larger. After exceeding the set threshold value (-20Pa), the air pressure sensor will send an electrical signal to the PLC controller 8. After receiving the electrical signal, the PLC controller 8 will remind the medical staff through the buzzer inside the operation display panel 46. When the medical staff hears the warning sound, they need to find the damaged part and use repair tools such as tape to repair the damaged part. When the medical staff cannot find the damaged part, it means that the damaged part is small and not easy to be found. The medical staff will send an electrical signal to the PLC controller 8 through the operation display panel 46. After receiving the electrical signal, the PLC controller 8 will control the linear motor 151 to drive the detection frame 152 to move back and forth on the upper surface of the isolation cover 3, and the detection frame 152 will drive the sealing strip 16 on the inner wall. The surface of the isolation cover 3 moves slowly. Since the blocking strip 16 is thick, it will squeeze the isolation cover 3 during the movement, and the blocking strip 16 moves slowly. When the blocking strip 16 blocks the damaged part, the external gas will not enter the isolation cover 3 through the damaged part, and the air pressure inside the isolation cover 3 will quickly drop toward the set threshold value. When the PLC controller 8 detects this change through the air pressure sensor, it will control the linear motor 151 to drive the detection frame 152 to move the set distance to the right (the length of the moving distance is the length of the distance between the blocking strip 16 and the moving path of the ball 21), so that the damaged part is located in the moving path of the ball 21, and then the PLC controller 8 controls the small electric push rod 18 to drive the detection cylinder 19 to move downward to the set position. The detection cylinder 19 will drive the lifting frame 20 and the ball 21 to contact the surface of the isolation cover 3, and after the ball 21 contacts the surface of the isolation cover 3, the reaction force drives the lifting frame 20 to move in the detection cylinder 19, refer to Figure 8When the lifting frame 20 moves in the detection cylinder 19, the telescopic water bag 24 will be stretched through the pressure plate 25, so that the pressure inside the telescopic water bag 24 becomes smaller, and part of the disinfectant in the annular water tank 28 will enter the telescopic water bag 24 through the liquid inlet pipe 29 and the corresponding second one-way valve 30 under the action of pressure. When the small electric push rod 18 stops moving, the PLC controller 8 will control the driving mechanism to control the moving plate 17 to move (the driving mechanism includes a track connected to the inside of the detection frame 152, and a track block is provided in the track. The track block is connected to the moving plate 17, and a driving motor is provided on the right side of the moving plate 17. The driving motor is connected to the side wall of the track through a gear rack assembly). The moving plate 17 will drive the small electric push rod 18, the detection cylinder 19, the lifting frame 20 and the ball 21 to move on the surface of the isolation cover 3. When the ball 21 and the lifting frame 20 move to the damaged part, they will be inserted into the damaged part under the elastic force of the spring (the ball 21 is small in size), and the lifting frame 20 moves downward. During the process, the trigger switch 22 is pressed, and the trigger switch 22 controls the buzzer inside the operation display panel 46 to work. The buzzer uses different tones to remind the operator that the damaged part has been found, and when the lifting frame 20 moves downward, the pressure plate 25 squeezes the telescopic water bag 24, so that the disinfectant inside the telescopic water bag 24 is transported to the annular ring 26 through the curved pipe 232 and the corresponding second one-way valve 30, and is sprayed to the damaged part and the ball 21 through the nozzle 27, thereby disinfecting the damaged part and the ball 21. The operator can quickly find the damaged part by the position of the ball 21. After finding the damaged part, the operator can control the small electric push rod 18 through the PLC controller 8 to drive the lifting frame 20 and the ball 21 away from the damaged part, and control the linear motor 151 to drive the detection frame 152 to move, and then use repair tools such as tape to repair the damaged part to prevent pathogens inside the stretcher 1 from continuing to seep out from the damaged part, thereby increasing the risk of infection for medical staff.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
