Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an air bag component used for endoscopic examination. Background Art

[0002] Colonoscopy and enteroscopy are commonly used fiber endoscopes in clinical practice. They can clearly detect intestinal lesions and treat some intestinal lesions, such as direct removal of benign lesions such as colorectal polyps, endoscopic hemostasis of intestinal bleeding, and removal of foreign bodies in the intestine. Intestinal loops are a phenomenon that occurs during colonoscopy. When patients undergo colonoscopy, the intestines continue to expand to the left and right, circle, and knot. This is the intestinal loop phenomenon.

[0003] At present, the diameter of the endoscope for colon examination is about 12-14mm, which makes it difficult to form a sufficient contact surface with the intestinal cavity during the process of unhooking the intestinal examination to drive the intestinal cavity to move with the endoscope. The efficiency of the rotation and pull-back technology of the endoscope body is not high, which makes it difficult to unhook, causing pain, discomfort and poor acceptance of patients. For example, patent announcement number CN208988833U discloses an airbag for auxiliary endoscopic examination. After the airbag is inflated, the contact surface with the intestinal cavity can be increased, thereby increasing the friction force, which solves the problem of unhooking the endoscope in the intestine to a certain extent. However, each airbag needs to be fixed to the endoscope body by a rubber band. The installation process is cumbersome and time-consuming. The elasticity of the rubber band is extremely high to ensure the sealing of the airbag. It is difficult to carry out in actual clinical work. It is bound to require a pre-sealed integrated airbag that is easy to install and disassemble on the endoscope body quickly for application in actual clinical work. Utility Model Content

[0004] The purpose of the utility model is to provide an airbag assembly for endoscopic examination, so as to solve the problem that the existing airbag assembly needs to be fixed with a rubber band during installation, the installation process is cumbersome and time-consuming, the elasticity requirements of the rubber band are extremely high to ensure the sealing of the airbag, it cannot meet the use requirements, and it is difficult to carry out in actual clinical work.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A balloon assembly for endoscopic examination comprises an annular balloon, wherein the annular balloon is composed of an inner membrane and an outer membrane to form a closed inflation cavity, the inner membrane is arranged in close contact with an endoscope body, a front end cap is arranged at one end of the annular balloon, and a rear end cap is arranged at the other end, both the front end cap and the rear end cap are provided with inflation ports, a connecting port is arranged on the annular balloon to be connected to a trachea, the trachea is connected to an air pump, a switch valve and a pressure sensor are arranged on the trachea, the front end cap and the rear end cap are both in annular shape, and inflation ring pads are respectively arranged between the front end cap and the rear end cap and the endoscope body.

[0007] Optionally, the annular airbag, the front end cap and the rear end cap are sleeved on the endoscope body, the front end cap is arranged close to one end of the endoscope body, and the inner diameters of the front end cap and the rear end cap are larger than the diameter of the endoscope body.

[0008] Optionally, a micro valve core is provided in the inflation port, and the front end cap and the rear end cap cooperate with the micro valve core to inflate the inflation port through an inflation pump.

[0025] like Figure 1-8An airbag assembly for endoscopic examination is shown, including an annular airbag 1, which is composed of an inner membrane 8 and an outer membrane 9 to form a closed inflation cavity, the inner membrane 8 is arranged in close contact with the endoscope body 6, a front end cap 2 is arranged at one end of the annular airbag 8, and a rear end cap 3 is arranged at the other end, and an inflation port 4 is arranged on the front end cap 2 and the rear end cap 3, a connecting port is arranged on the annular airbag 8 to connect with the trachea 5, the trachea 5 is connected to the air pump, a switch valve and a pressure sensor are arranged on the trachea 5, the front end cap 2 and the rear end cap 3 are both in the shape of an annulus, and an inflation ring cushion 10 is respectively arranged between the front end cap 2 and the rear end cap 3 and the endoscope body 7. It should be noted that the contact surface between the inflatable ring pad 10 and the endoscope body 7 is an anti-slip layer to ensure the stability of the front end cap 2 and the rear end cap 3 after installation. The air pump works in conjunction with the trachea 5, the switch valve, and the pressure sensor to inflate and exhaust the annular airbag 1 to achieve the effect of expanding and fixing it to the desired position. The working principle is an existing mature technology and is not repeated here. The annular airbag 8 is fixedly connected to the front end cap 2 and the rear end cap 3, and both are made of medical plastics. The connection of the annular airbag 8 is thickened to avoid pulling the annular airbag 8 during the expansion of the annular airbag 8 or the adjustment of the spacing between the front end cap 2 and the rear end cap 3, thereby damaging the annular airbag 8 and affecting its subsequent use; this airbag assembly is also applicable to other types of fiber endoscopes.

[0026] Specifically, the annular airbag 8, the front end cap 2 and the rear end cap 3 are sleeved on the endoscope body 7, the front end cap 2 is arranged close to one end of the endoscope body 7, and the inner diameters of the front end cap 2 and the rear end cap 3 are larger than the diameter of the endoscope body 7. It should be noted that the arrangement of the front end cap 2 and the rear end cap 3 having an inner diameter larger than the endoscope body 7 will facilitate their rapid installation and removal on the endoscope body 7, thereby improving their working efficiency.

[0027] Specifically, a micro valve core is arranged in the inflation port 4, and the front cap 2 and the rear cap 3 are inflated with the micro valve core through an inflation pump. It should be noted that the inflation port 4 and the micro valve core are used to inflate and exhaust the front cap 2 and the rear cap 3.

[0028] Specifically, the front end cap 2 and the rear end cap 3 are injection molded, and the front end cap 2 and the rear end cap 3 are provided with a hollow cavity. The inner circles of the front end cap 2 and the rear end cap 3 are both opened, and the inflatable ring cushion 10 is provided at the openings. The front end cap 2 and the rear end cap 3 are respectively connected to the inflatable ring cushion 10 through the openings. It should be noted that the air pump works in conjunction with the inflatable port 4 and the micro valve core to inflate the front end cap 2 and the rear end cap 3, so that the inflatable ring cushion 10 expands, and then fits and clamps the endoscope to ensure that the airbag assembly is fixed on the endoscope.

[0029] The working principle of this specific embodiment is as follows: when the airbag assembly needs to be used, the front end cap 2, the annular airbag 1, and the rear end cap 3 are first sleeved on the endoscope body 7, and then the installation position of the annular airbag 1 is adjusted as needed, and the spacing between the front end cap 2 and the rear end cap 3 is adjusted. When installed in place, the front end cap 2 and the rear end cap 3 are inflated by the air pump in conjunction with the inflation port 4 and the micro valve core to expand the inflatable ring cushion 10, thereby making it fit and clamp the endoscope to ensure that the airbag assembly is fixed on the endoscope body 6. Then, when the annular airbag 1 needs to be operated during the endoscopic inspection, the annular airbag 1 is inflated and exhausted by the air pump in conjunction with the trachea 5, the switch valve, and the pressure sensor to meet the use requirements. When the airbag assembly is used, the gas in the front end cap 2 and the rear end cap 3 is discharged through the inflation port 4 and the micro valve core, and the inflatable ring cushion 10 is reset. At this time, the front end cap 2, the annular airbag 1, and the rear end cap 3 can be removed.

[0030] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
