Description

Technical Field

[0001] This utility model belongs to the field of medical equipment technology, specifically relating to a ventilation device for painless endoscopic diagnosis and treatment. Background Technology

[0002] Painless gastroscopy, bronchoscopy, and endoscopic procedures mostly utilize total intravenous anesthesia, without endotracheal intubation. Occasionally, drug-induced respiratory depression may occur during anesthesia, manifesting as airway obstruction, apnea, and decreased blood oxygen saturation. This is primarily caused by collapse of oral soft tissues obstructing the airway and affecting oxygen supply. Currently, the gastroscopy masks or nasal cannulas commonly used in clinical practice cannot adequately deliver oxygen to the lungs for oxygenation. Because endoscopic procedures share a channel with the upper respiratory tract, patients with severe respiratory depression often require removal of the endoscope and cessation of the procedure, followed by mask ventilation to improve oxygenation and prevent complications such as myocardial ischemia and cerebral hypoxia caused by hypoxemia. This increases the risk to patients, prolongs treatment time, and reduces the experience for the gastroscopy operator. Nasopharyngeal airways can improve airway obstruction, but they are not used as a routine treatment in clinical practice. Furthermore, this device has specific indications for use, leading to poor patient compliance and potential complications such as nasal mucosal bleeding and edema. Studies have shown that drug-induced respiratory depression and airway obstruction leading to accidental death are among the leading causes of death during painless endoscopy. Therefore, a ventilation device needs to be designed to address respiratory depression during painless endoscopic procedures. Utility Model Content

[0003] This invention provides a ventilation device for painless endoscopic diagnosis and treatment to address the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A ventilation device for painless endoscopic diagnosis and treatment includes a ventilation tube, an oxygen connector at the distal end of the ventilation tube for connecting an oxygen tube, an oxygen outlet at the proximal end of the ventilation tube, an arc-shaped fitting surface near the proximal end of the ventilation tube for fitting against the outer wall of the endoscopic tube, a plurality of suction cups on the arc-shaped fitting surface, the suction cups being connected to the output end of a valve via suction cup conduits disposed within the wall of the ventilation tube, and a connector at the input end of the valve for connecting a syringe.

[0006] Furthermore, the near end of the ventilation duct is provided with an arc-shaped head to prevent the ventilation duct from scratching the human body.

[0007] Furthermore, each of the aforementioned straws corresponds to a suction cup conduit, which should facilitate the prevention of interference between the suction cups.

[0008] Furthermore, the valve includes a valve body with multiple output ends on the lower surface of the valve body. Each suction cup conduit is connected to a different output end. An input end is provided on the side of the valve body. A valve core is provided 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. A sealing gasket is fixedly connected to the lower surface of the valve core to achieve sealing of the output ends.

[0009] Furthermore, the ventilation duct is equipped with graduations.

[0010] Furthermore, the oxygen outlet has two locations, both situated on the arc-shaped head.

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

[0012] The ventilation tube of this invention can be inserted into the human body along with the endoscope tube, and then oxygen can be delivered into the human body through the ventilation tube, which effectively improves the respiratory depression problem in painless endoscopic diagnosis and treatment.

[0013] This invention features an arc-shaped fitting surface near the proximal end of the ventilation tube, which effectively ensures the fitting of the ventilation tube and the endoscope tube, guarantees the effective adsorption of the suction cup, and ensures that the ventilation tube can be inserted synchronously with the endoscope tube. When the ventilation tube is delivered to the appropriate position, air can be introduced into the suction cup through the valve to turn the suction cup into a positive pressure, thus completing the separation of the ventilation tube and the endoscope tube.

[0014] In this invention, each suction cup is connected to the valve through a different suction cup conduit. After the valve is closed, there is no mutual interference between the suction cups, effectively ensuring the suction performance of the suction cups. Attached Figure Description
