Description

Technical Field

[0001] The invention relates to the field of medical instruments for swallowing function, in particular to an improved gas pulse instrument for swallowing assessment. Background Art

[0002] Dysphagia refers to the process in which food cannot be safely and effectively transported to the stomach due to damage to the structure and / or function of the mandible, lips, tongue, soft palate, throat, esophagus and other organs. The main causes of dysphagia are: central nervous system diseases (such as stroke, brain trauma, brain tumors, Parkinson's disease, etc.); organic diseases of the oropharynx (such as oral and head and neck malignant tumors or growths; oral, nasopharyngeal and head and neck radiotherapy or chemotherapy, etc.).

[0003] In the prior art, the swallowing air pulse trainer has a simple structure, connected by a hose and a ball. When in use, the trachea is aligned with the upper palate and the ball is manually pressed. It is easy to operate, but long-term use increases the labor intensity of medical staff, and the airflow size cannot be adjusted to evaluate the swallowing function. There are also existing ones that connect the hose and oxygen and realize swallowing evaluation through a pressure reducing valve, but the sealing between the pressure reducing valve and the hose is not good. At the same time, when in use, when it needs to be fixed on a wall or a horizontal plane, the position of the pressure reducing valve is not easy to fix. When in use, the pressure reducing valve needs to be held by hand, which increases the labor intensity of medical staff. Summary of the invention

During training, an air pressure plan can be formulated according to the pressure evaluation to facilitate treatment.

[0034] like Figure 2 and 3 As shown, the pressure reducing valve 1 includes a base 11 located at the bottom, and vents 12 are provided at both ends of the pressure reducing valve 1. The vent 12 at one end is an air inlet, and the vent 12 at the other end is an air outlet. Multiple limiting holes 121 are opened at the outer end of the vent 12, and a connecting plate 13 is provided on the side of the vent 12. A sealing sleeve 131 and multiple limiting columns 132 are respectively provided at one end of the connecting plate 13, and the limiting columns 132 are arranged at the outer end of the sealing sleeve 131. A rubber sealing ring 14 is provided on the sealing sleeve 131. The sealing sleeve 131 and the rubber sealing ring 14 are connected to form a whole body that is sealed with the vent 12, and the limiting columns 132 are sealed with the limiting holes 121.

[0035] The other end of the connecting plate 13 is provided with a vent pipe 15, which is tightly sleeved and connected with one end of the air inlet pipe 2 and the air outlet pipe 3, respectively. The ends of the air inlet pipe 2 and the air outlet pipe 3 are connected with a clamp 16, and the pipe bodies of the air inlet pipe 2 and the air outlet pipe 3 are fixed by fasteners 161 on the clamp 16 to ensure the sealing performance with the vent pipe 15. The air inlet pipe 2, the pressure reducing valve 1 and the air outlet pipe 3 are connected as a whole.

[0036] like Figure 1 and 4As shown, a mounting component 4 is provided below the pressure reducing valve 1, and the mounting component 4 includes a limiting cylinder 41, and the base 11 provided at the bottom end of the pressure reducing valve 1 is adapted to the limiting cylinder 41.
