DETAILED DESCRIPTION

[0031] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example 1

[0033] like Figure 1-2As shown, the present invention provides a mobile inspection vehicle 10 with a negative pressure isolation endoscope operation device, including a negative pressure chamber 5 arranged on the inspection vehicle 10, a protective cover 8 on the negative pressure chamber 5 is selected to be made of a transparent plastic material, and the transparent plastic material allows medical personnel to observe the status of the patient in the negative pressure chamber 5 at any time, and a negative pressure air filter 1 is arranged on the front side of the negative pressure chamber 5, and a control device, a negative pressure device, a power supply and a power device are arranged in the negative pressure air filter 1, wherein the control device, the negative pressure device and the power device are controlled and adjusted by a plurality of knobs 11 arranged on the negative pressure air filter 1. Among them, a first air duct 2 and a second air duct 3 are arranged on the negative pressure air filter 1, and the second air duct 3 is fixedly connected to the front end 4 of the negative pressure chamber 5, and the second air duct 3 provides negative pressure for the negative pressure chamber 5, and the negative pressure air filter 1 extracts the gas exhaled by the patient from the negative pressure device for filtering, that is, the negative pressure air filter 1 extracts and filters the air in the negative pressure chamber 5. Among them, the negative pressure air filter 1 is provided with an H14 type or higher level HEPA filter to physically block the virus particles from polluting the surrounding environment. (Since the negative pressure chamber 5 and the negative pressure air filter 1 are both existing technologies, they will not be described here.) In this embodiment, the lower part of the frame 14 provided on the inspection vehicle 10 is provided with a roller 16, which can facilitate the movement of the patient and adjust the required position; the roller 16 is also provided with a brake pedal 12, and when the position of the inspection vehicle 10 needs to be fixed, the user can step on the brake pedal 12 to fix the inspection vehicle 10.

[0034] In this embodiment, a through hole structure is provided on the right side of the rear end 6 of the negative pressure chamber 5. During endoscopy, the patient is usually in the left side lying position, so the operator can only perform examination on the right side of the negative pressure chamber 5. The through hole structure is selected as a round hole or an elliptical hole. In this embodiment, the through hole structure is selected as a round hole, and an endoscope inspection component 7 is provided on the round hole of the through hole structure. Figure 2 and Figure 4As shown, the specific structure of the endoscope inspection component 7 includes an upper barrel 73, a second barrel 74 and a lower barrel 75 connected in sequence at the lower side of the first ring 72. During endoscopy, the patient's lips should bite the second ring 74. When the patient is in a left-side lying position, the lips are about 15 cm away from the bed surface, so the endoscope inspection component 7 is about 15 cm away from the bed surface. When the patient is in a left-side lying position, the left lower limb is straightened and the right lower limb is bent. The distance between the lips and the component 7 is about 15-20 cm, so the length of the upper barrel 73 in this embodiment is selected to be 15 cm, and the second ring 74 is the place where the patient bites with his mouth in the negative pressure chamber 5. In this embodiment, an arc piece 76 extending outward is provided at the port position of the lower barrel 75, and the arc piece 76 is connected to a silicone sleeve 761. The arc piece 76 is set to a tongue-shaped structure, and the tongue-shaped structure can more conveniently press the tip of the patient's tongue to allow the endoscope to pass through the mouth smoothly. Since the upper barrel 73, the second circle 74 and the lower barrel 75 are provided with a barrel channel 71 for endoscopic examination, the current maximum diameter of the endoscope is 1.3 cm, so the diameter of the barrel channel 71 can be 1.4 cm, and the outer side of the first circle 72 is fixedly connected to the inner circle of the through-hole structure in a closed manner, and a plurality of first negative pressure vents 77 are provided on the upper barrel 73. Preferably, the number of the first negative pressure vents 77 is between 6 and 8. In the present embodiment, the number of the first negative pressure vents 77 is 6. When performing a gastroscopy, the medical staff asks the patient to bite the lower barrel 75, and then enter the endoscope from the barrel channel 71 for operation. The upper barrel 73, the second circle 74, the lower barrel 75, the arc piece 76 and the silicone sleeve 761 utilize the principle of an odor-proof floor drain to act as a one-way valve. If the patient vomits, aerosols and digestive tract secretions cannot leak out of the negative pressure chamber 5. During the endoscopic examination, the patient may vomit violently. Even if a small amount of aerosol leaks out from the gap of the silicone sleeve 761, since the first negative pressure vent 77 is arranged in the middle of the upper barrel 73, which is in the negative pressure area, even if aerosol leaks out, it will be sucked away and filtered by the negative pressure, and the aerosol will never overflow outside the negative pressure chamber 5.

[0035] like Figure 3 As shown, the preferred technical solution is that one or two second negative pressure vent holes 771 are further provided on the lower cylinder body 75. Because there is negative pressure in the negative pressure chamber 5, in case the patient does not cooperate well, the overflowing aerosol can also return to the negative pressure chamber 5 from the provided second negative pressure vent hole 771. The function of the second negative pressure vent hole 771 is to prevent the aerosol from leaking directly out of the chamber, and the negative pressure is sucked back through the second negative pressure vent hole 771, which not only ensures that the cylinder channel 71 serves as an air inlet channel, but also ensures that the gas in the patient's digestive tract will not overflow due to vomiting, and also plays a role in protecting the safety of medical staff.

[0036] like Figure 4 and Figure 5As shown, in order to expand and contract the positions of the barrel 73, the lower barrel 75 and the arc-shaped piece 76 within a shorter range or to adjust the positions at a small angle, a plurality of circles of bellows 78 are provided at the lower side of the first circle 72 and the connection between the upper barrel 73. The medical staff can press down or pull up the side of the barrel channel 71 to extend or contract the bellows 78 in the barrel channel 71, so that the barrel 73, the lower barrel 75 or the arc-shaped piece 76 can be expanded and contracted or adjusted within a small angle range, thereby achieving the effect of fine-tuning.

[0037] In order to protect the tube channel 71 in the first circle opening 72, a buckle cover 79 for sealing is provided on the first circle opening 72, and a knob 710 is provided on the buckle cover 79. Since the knob 710 is made of soft material, the column provided on the knob 710 can be smoothly pressed into the blind hole on the first circle opening 72 (not shown in the figure). The knob 710 and the blind hole are connected by interference fit, and it is ensured that it can be smoothly rotated. When the knob 710 is rotated with a finger, it can be pressed into the blind hole on the first circle opening 72 and can also be rotated. When performing endoscopic examination, the medical staff rotates the knob 710 with a finger, which can drive the buckle cover 79 to rotate and open, so that the opening of the tube channel 71 is smoothly exposed, which plays a role in facilitating the medical staff to smoothly perform endoscopic surgery; after the endoscopy is completed, the medical staff rotates the knob 710, and the buckle cover 79 rotates to close the tube channel 71, which plays a role in ensuring cleanliness and hygiene.

[0038] like Figure 6 As shown, in order to make gastroscopy more convenient, arc-shaped recesses 711 corresponding in shape are provided on the first circle 72 and the tube channel 71, and the ends thereof are provided with arc-shaped recesses 711 protruding outward and recessed inward, which are more suitable for the entry of surgical instruments and the adjustment of angles.

[0039] like Figure 7 As shown, in the preferred technical solution, plugs 712 are evenly distributed along the circumference of 360° on the first circle 72. In this embodiment, six plugs 712 are arranged on the first circle 72, and the angle between two plugs 712 is 60°. A thread 714 made of a flexible material is fixedly connected to each plug 712, and the end of the thread 714 is fixedly connected to a fixed column 713 fixed to the upper barrel 73. When the bellows 78 is in the extended state, if it is found that the position of the lower barrel 75 or the arc-shaped piece 76 is not convenient for the patient to bite, one or two plugs 712 corresponding to the relative direction position can be pulled, and the thread 714 on the plug 712 will drive the lower barrel 75 or the arc-shaped piece 76 to be bent at a certain angle, so as to adjust a certain small angle range, that is, to achieve the effect of fine-tuning.

[0040] like Figure 8As shown, in this embodiment, medical personnel can also press the side of the tube channel 71 to extend and contract the bellows 78, so as to allow the tube body 73, the lower tube body 75 or the arc-shaped piece 76 to extend or retract or adjust within a small angle range, and also achieve the effect of fine-tuning.

[0041] Example 2

[0042] The mobile inspection vehicle provided with a negative pressure isolation endoscope operation device provided in this embodiment is further improved on the basis of the embodiment 1. The other structures are the same, and the difference is that:

[0043] like Figures 9 to 11 As shown, an auxiliary inspection component 9 is provided on the negative pressure chamber 5 on the inspection vehicle 10. The preferred position is that the auxiliary inspection component 9 is provided at the rear end 6 of the negative pressure chamber 5 and close to both sides of the endoscopic inspection component 7, or the auxiliary inspection component 9 is provided on one side of the endoscopic inspection component 7. Among them, the specific structure of each auxiliary inspection component 9 includes a through hole arranged at the rear end 6 of the negative pressure chamber 5 near the endoscope inspection component 7, and a third circle 97 made of hard material is fixedly connected to the through hole. The inside of the third circle 97 is a through hole connected to the negative pressure chamber 5, and the through hole is fixedly connected to the third circle 97, and the third circle 97 is fixedly connected to the four sides of the diaphragm 96. A plurality of dividing lines 95 are provided on the diaphragm 96, and the dividing lines 95 divide it into a plurality of block structures. The provided block structure can facilitate the medical staff's hands to smoothly pass through the through hole to enter the negative pressure chamber 5 or move out of the negative pressure chamber 5. The block structure is a structure overlapped with each other on the diaphragm 96. This structure can make it more convenient to open or close the through hole smoothly. If the patient's position is not suitable, the medical staff can smoothly extend both hands or one hand to help swing the patient's position until the patient reaches a suitable position. Another preferred structure is that a soft cover 98 is provided on the lower side of the third ring opening 97. The soft cover 98 is in the shape of a glove or a sleeve made of materials such as silicone or rubber. The glove-shaped or sleeve-shaped silicone cover inside plays a role in adjusting the diagnosis and treatment and placing the patient's position without direct contact with the patient.

[0044] In this embodiment, a rotating shaft 91 is further provided on the side close to the third circle opening 97. The rotating shaft 91 is fixedly connected to one end of the connecting rope 92, and the other end of the connecting rope 92 is movably connected to a protrusion 94 arranged at the center position of the sealing buckle cover 93. A circular flange is arranged on the inner side of the sealing buckle cover 93, which corresponds to and is engaged with the groove structure arranged on the third circle opening 97. When the medical staff's hand is withdrawn from the negative pressure chamber 5, the medical staff's hand can pick up the sealing buckle cover 93 on the connecting rope 92, and use the sealing buckle cover 93 to tighten and seal the third circle opening 97. In addition, if the diaphragm 96 and the soft cover 98 in the assembly fail, it can still ensure that the normal negative pressure value is maintained in the negative pressure chamber 5.

[0045] The present invention has been described in detail above with reference to the accompanying drawings for specific implementation modes and embodiments of the present invention. However, the present invention is not limited to the above implementation modes and embodiments. Various changes can be made within the knowledge scope of those skilled in the art without departing from the concept of the present invention.
