Embodiment 1

[0036] Embodiment 1, as shown in the figure,

[0037]A handle-type lavage device, comprising a handle 2, the handle 2 is connected to the handle 1 of the fiberoptic bronchoscope, the handle 2 is provided with a suction device, and the liquid suction device includes a liquid inlet 3 and a liquid outlet 4. The liquid inlet 3 is used to communicate with the lavage fluid collection device 5, the liquid outlet 4 is used to communicate with the lavage hole 6 of the fiberoptic bronchoscope catheter 7, and the liquid suction device is used to extract The lavage fluid collects the lavage fluid in the device 5 and presses it into the lavage hole 6 of the catheter 7 .

[0038] In the handle 1 type lavage device of the present application, the handle 2 is matched with the handle 1 in the traditional fibrous bronchus structure. Since the handle 2 is provided with a pumping device, the lavage fluid can be collected by the pumping device during use by the doctor. The lavage fluid in the dev...

Embodiment 2

[0042] Embodiment 2, as shown in the figure:

[0043] In the handle 1 type irrigation device structure as described in Embodiment 1, the liquid pumping device includes a liquid cylinder 16 and a piston 9 matched with the liquid cylinder 16, and a push rod 10 is arranged on the piston 9, The bottom of the hydraulic cylinder 16 is provided with a first one-way valve 11 and a second one-way valve 12, the outlet of the first one-way valve 11 is the liquid outlet 4, and the outlet of the second one-way valve 12 is The inlet is the liquid inlet 3.

[0044] When in use, when the push rod 10 pushes the piston 9 to move upward in the liquid cylinder 16, under the action of negative pressure, the first one-way valve 11 is closed, the second one-way valve 12 is opened, and the lavage fluid is collected by the lavage fluid. The device 5 enters the liquid cylinder 16 through the second one-way valve 12, and when the piston 9 moves toward the bottom of the liquid cylinder 16, under the act...

Embodiment 3

[0052] Embodiment 3, as shown in the figure:

[0053] In the structure of the handle 1 type irrigation device as described in Embodiment 1, the pumping device is a pumping device, and the pumping device includes a liquid pump 18, and the inlet of the liquid pump 18 is the liquid inlet 3. The outlet of the liquid pump 18 is the liquid outlet 4 .

[0054] Further preferably, the liquid pump 18 is connected with a first switch 19 for controlling its start and stop. It is convenient to control the start and stop of the liquid pump 18.

[0055] Further preferably, the first switch 19 is arranged on the handle 2 . When the doctor uses the fiberoptic bronchoscope, one hand grasps the handle 2, so the first switch 19 is arranged on the handle 2, and in the normal operation state, the doctor can also control the first The switch 19 further controls the start and stop of the pumping device, which further facilitates the doctor's use.

[0056] Preferably, the handle 2 is further prov...

Abstract

The invention belongs to the technical field of medical devices, and particularly relates to a handle-type irrigation device and a fiberoptic bronchoscope using the same. The handle-type irrigation device includes a handle, and the handle is connected to the handle of the fiberoptic bronchoscope. The handle is provided with a liquid pumping device, the liquid pumping device includes a liquid inlet and a liquid outlet, the liquid inlet is used to communicate with the lavage fluid collection device, and the liquid outlet is used to communicate with the fiber bronchus The lavage hole of the mirror catheter is connected, and the liquid pumping device is used to extract the lavage fluid in the lavage fluid collecting device and press it into the lavage hole of the catheter. The handle-type lavage device of the present application can be used in conjunction with the existing fiberoptic bronchoscope structure, and does not need to replace the whole set of fiberoptic bronchoscope structure. In this way, it is convenient for doctors to use and reduces the risk of medical accidents, and also reduces the cost of hospital product renewal. The input cost is beneficial to the popularization of the handle type irrigation device of the present application.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a handle-type lavage device and a fiber bronchoscope using the lavage device. Background technique [0002] Fiberoptic bronchoscopy is an endoscopic technique that can directly see the condition of the human respiratory airway, determine the location and manifestation of the lesion, and at the same time perform bronchial lavage, suction of sputum, and hemostasis under direct vision. [0003] In the current clinic, due to long-term bed rest, weak cough and sputum, or insufficient airway humidification due to long-term use of ventilators, critically ill patients will produce a large amount of sputum and block the bronchi. The ordinary suction method is limited by the length of the suction tube , the sputum suction site is mostly located above the bronchial carina, unable to reach the bronchi, resulting in the inability to suck out the sputum in the deep part of ...
