Suction tube and suction system for continuous negative pressure in oral cavity

Abstract

The disclosure relates to an oral continuous negative pressure suction tube and a suction system, including a negative pressure tube with a blocked head end and a suction head sleeved outside the head end of the negative pressure tube, the suction head includes a tube sleeve, and the tube sleeve is connected to the suction piece One side of the suction sheet is provided with a plurality of suction holes, the suction sheet has a gas passage, and the gas passage can keep the suction holes in communication with the inner cavity of the negative pressure pipe at all times during the rotation of the sleeve along the negative pressure pipe. The number of the suction pieces is two, the two suction pieces are arranged symmetrically with respect to the central axis of the sleeve, and the suction holes are arranged on the same side of the two suction pieces.

Description

technical field [0001] The disclosure belongs to the technical field of medical equipment, and in particular relates to an oral cavity continuous negative pressure suction tube and a suction system. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Tracheal intubation and tracheotomy are commonly used respiratory therapy methods for critically ill patients and are widely used in clinical practice. However, after tracheal intubation and incision, the oral cavity remains open for a long time, making the patient unable to chew, swallow, and eat normally, the oral mucosal resistance and self-purification function are reduced, and oral bacteria multiply; , the protective function of the epiglottis is reduced or lost, which increases the probability of oral infection transfer; in addition, the use of sedatives and muscle relaxants, patients with aspiratio...

Problems solved by technology

[0006] (2) Because the position of the suction head relative to the buccal side of the mouth cannot be adjusted, the suction hole may be close to the buccal skin during use, and long-term negative pressure suction may cause ulceration of the buccal skin, which is not suitable for long-term use

[0007] (3) In some negative pressure suction tubes that increase the volume of the suction head, the suction head is generally a trumpet-shaped structure with increased volume. In this structure, the part that participates in the suction of saliva secretion at any time is still the part near the buccal side , most of the volume is wasted
