Flusher for otolaryngology department

Abstract

The invention discloses a flusher for the otolaryngology department, and belongs to the technical field of medical instruments, the flusher comprises a liquid storage bottle, the bottom of the liquid storage bottle is communicated with a first hose, and the first hose is provided with a flow rate valve; the buffer cavity is an elastic cavity, the top of the buffer cavity communicates with the other end of the first hose, and the other end of the buffer cavity communicates with a second hose; one end of the first hard tube is communicated with the second hose, the other end of the first hard tube is communicated with a second hard tube, and the first hard tube and the second hard tube are arranged at an angle; an accelerating piece is arranged at the junction of the first hard pipe and the second hard pipe, the accelerating piece is of a circular-truncated-cone-shaped structure, the large-inner-diameter end of the accelerating piece is fixedly connected to the pipe wall of the first hard pipe, and the small-inner-diameter end of the accelerating piece extends into the second hard pipe; the device is simple in structure, convenient to use, capable of improving the flushing effect and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to an irrigator for otorhinolaryngology. Background technique [0002] For otolaryngology, since the ear, nose, and throat have passages and are connected to the outside world, they are easily affected by the external environment, causing discomfort, and severe cases can cause lesions. It is very routine to rinse the affected area. For example, with the popularization of nasal endoscopy and ear endoscopy, endoscopic surgery has become a routine treatment method in otolaryngology. In order to prevent postoperative adhesions, the surgical site needs to be rinsed. Larger, when flushing with lotion, it is necessary to increase the flow rate of lotion to wash away the above secretions, but the flushing pressure of the flushing device currently used is small and cannot be effectively flushed. For example, the rinse bottle for flushing the nasal cavity has a structure ...

[0002] For otolaryngology, since the ear, nose, and throat have passages and are connected to the outside world, they are easily affected by the external environment, causing discomfort, and severe cases can cause lesions. It is very routine to rinse the affected area. For example, with the popularization of nasal endoscopy and ear endoscopy, endoscopic surgery has become a routine treatment method in otolaryngology. In order to prevent postoperative adhesions, the surgical site needs to be rinsed. Larger, when flushing with lotion, it is necessary to increase the flow rate of the lotion to wash off the above secretions, but the flushing pressure of the current flushing device is low, so it cannot be effectively flushed

For example, the rinse bottle for flushing the nasal cavity has a structure of a liquid storage bottle, which holds the lotion, and a cleaning tube is installed at the mouth of the liquid storage bottle. The cleaning tube is a bent tube, and the end of the bent tube is an arc-shaped head for facing the nostril , Squeeze the liquid removal bottle to rush the lotion from the bent tube to the nasal cavity, but the nasal cavity is narrow and has a lot of secretions. The force is weak, so the flushing effect is not good, and in order to wash off the secretions, increase the squeezing force, or keep the lotion bottle to store a sufficient amount of lotion, after repeated squeezing, it takes a lot of physical strength; therefore, it can be designed Under the same extrusion force, the impact force of the lotion is increased to improve the flushing effect. For this reason, the present invention proposes a flushing device
