Description

Technical Field

[0001] The present invention belongs to the technical field of medical equipment, and in particular relates to a ventilation device used for painless endoscopic diagnosis and treatment. Background Art

[0002] Painless gastroscopy, tracheoscopy, and bronchoscopy are mostly performed under total intravenous anesthesia without endotracheal intubation. Respiratory depression caused by drugs may occasionally occur during anesthesia, manifested as airway obstruction, apnea, and decreased blood oxygen saturation. The main reason is that the collapse of oral soft tissue blocks the respiratory tract and affects the oxygen supply. The gastroscopy mask or nasal catheter commonly placed in clinical practice cannot deliver oxygen to the lungs for adequate oxygenation. Since endoscopic diagnosis and treatment share the same channel with the upper respiratory tract, patients with severe respiratory depression often need to exit the endoscope and stop the operation, perform mask pressurized ventilation, improve oxygenation, and prevent hypoxemia from causing complications such as myocardial ischemia and cerebral hypoxia. This increases the risk of patients seeking medical treatment, prolongs the diagnosis and treatment time, and reduces the experience of gastroscopy operators. The nasopharyngeal airway can improve airway obstruction, but it is not used as a routine treatment in clinical work. In addition, the device has indications for use, and patient compliance is poor. It can also cause nasal mucosal bleeding, edema, and other conditions. Studies have shown that accidental death caused by respiratory depression and airway obstruction associated with anesthetics is one of the biggest causes of death in painless endoscopic procedures. Therefore, it is necessary to design a ventilation device to improve the problem of respiratory depression in painless endoscopic diagnosis and treatment. Summary of the invention

[0003] In view of the above problems, the present invention provides a ventilation device for painless endoscopic diagnosis and treatment.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] A ventilation device for painless endoscopic diagnosis and treatment comprises a ventilation pipe, wherein an oxygen connector is arranged at the distal end of the ventilation pipe for connecting an oxygen tube, an oxygen outlet is opened at the proximal end of the ventilation pipe, an arcuate fitting surface is arranged at a position close to the proximal end of the ventilation pipe, the arcuate fitting surface is used to fit with the outer wall of the endoscope pipe, a plurality of suction cups are arranged on the arcuate fitting surface, the suction cup is connected to the output end of the valve through a suction cup catheter, the suction cup catheter is arranged in the pipe wall of the ventilation pipe, and a connector is arranged at the input end of the valve for connecting a syringe.

[0006] Furthermore, a circular arc head is provided at the proximal end of the ventilation pipe to prevent the ventilation pipe from scratching the human body.

[0007] Furthermore, each of the suction tubes corresponds to a suction cup guide tube, which should be convenient for preventing the suction cups from interfering with each other.

[0008] Furthermore, the valve includes a valve body, a plurality of output ends are arranged on the lower surface of the valve body, each of the suction cup guide tubes is connected to a different output end, an input end is arranged on the side of the valve body, a valve core is arranged inside the valve body, a valve stem is fixedly connected to the upper end of the valve core, the valve stem passes through the valve body and is threadedly connected to the valve body, and a sealing gasket is fixedly connected to the lower surface of the valve core to achieve sealing of the output end.

[0009] Furthermore, a scale is provided on the ventilation duct.

[0010] Furthermore, there are two oxygen outlets, both of which are located on the arc head.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] The ventilation tube of the present invention can enter the human body along with the endoscope tube, and then deliver oxygen into the human body through the ventilation tube, effectively improving the respiratory depression problem in painless endoscopic diagnosis and treatment;

[0013] The present invention provides an arc-shaped fitting surface at a position near the proximal end of the ventilation pipe, which effectively ensures the fitting of the ventilation pipe and the endoscope pipe, ensures the effective adsorption of the suction cup, and ensures that the ventilation pipe can enter synchronously with the endoscope pipe. When the ventilation pipe is delivered to a suitable position, air can be introduced into the suction cup through a valve to convert the suction cup into a positive pressure, thereby completing the separation of the ventilation pipe and the endoscope pipe.

[0014] The suction cups of the present invention are connected to the valve through different suction cup conduits. After the valve is closed, there is no mutual interference between the suction cups, thereby effectively ensuring the adsorption performance of the suction cups. BRIEF DESCRIPTION OF THE DRAWINGS
