Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a bronchial tube with a spray therapy function. Background Technology

[0002] Existing electronic bronchoscopes and disposable electronic bronchial imaging catheters both have instrument channels, which can also be used to administer medication to patients. However, the medication sprayed from the instrument channels of these two types of endoscopes is a stream of water, which has a small coverage area during treatment. Moreover, the medication is concentrated during spraying and is easily lost, resulting in a great waste of medication. The affected area does not absorb the medication sufficiently, and the treatment effect is not obvious. Furthermore, medication cannot be sprayed during suction or when the instrument is removed, which greatly reduces the treatment efficiency. In order to address the above-mentioned shortcomings, this application is made. Utility Model Content

[0003] The purpose of this invention is to provide a bronchial catheter with a spray therapy function. Based on the bronchoscope instrument channel, a spray channel is added and a nozzle capable of spraying atomized medication is provided. This solves the problems of water jet spraying in traditional bronchial imaging catheters and the inability to spray medication during suction or instrument removal.

[0004] To address the aforementioned problems, this utility model provides a bronchial catheter with a spray therapy function, comprising an insertion part and a handle operating end. The insertion part includes a catheter body, an instrument channel and a spray channel disposed within the catheter body, and a tip seat mounted at the end of the catheter body. The tip seat is provided with an instrument channel opening connected to the instrument channel and a spray port connected to the spray channel. The spray port includes a vortex chamber and several tangential structures disposed within the vortex chamber. The vortex chamber is provided with a constriction channel and a funnel-shaped nozzle connected to the constriction channel. After the liquid medicine enters the spray port, it can rotate within the vortex chamber under the action of the tangential structures and be sprayed out in a mist form under the action of the constriction channel and the funnel-shaped nozzle. The handle operating end is provided with a spray channel inlet connected to the spray channel and a drug delivery port connected to the instrument channel. The drug delivery port is used for drug delivery and for assisted treatment with a miniature medical device.

[0005] The mist-sprayed medication can cover a large area, has good absorption, and is not easily lost, reducing medication waste; while retaining the instrument channel, the addition of a spray channel does not affect the endoscope's original instrument placement and suction functions.

[0006] According to one embodiment of the present invention, the operating end of the handle is further provided with a suction port connected to the instrument channel for performing suction operations.

[0007] According to one embodiment of the present invention, the bronchial catheter with spray treatment function also includes a camera module, which is mounted on the tip seat to form an electronic bronchial imaging catheter. The power supply line and signal line of the camera module extend through the catheter body to the handle operation end.

[0008] According to one embodiment of the present invention, a Luer connector is provided at the inlet of the spraying channel to facilitate the connection between the inlet of the spraying channel and the drug delivery device.

[0009] Optionally, the instrument channel and the spray channel are pipes provided in the catheter body, that is, the instrument channel and the spray channel are separate pipes that pass through the catheter body.

[0010] Optionally, the instrument channel and the spray channel are channels formed inside the catheter body, that is, two channels are directly formed in the catheter body.

[0011] According to one embodiment of the present invention, the inlet of the spray channel, the drug delivery port, and the suction port are respectively located at different end faces of the handle operation end, which makes them easy to distinguish during use and convenient to use, and avoids interference between the instruments.

[0012] According to one embodiment of the present invention, the inner wall of the spray nozzle is provided with a limiting step for limiting the spray channel, so as to ensure the relative position of the spray channel and the spray nozzle during installation.

[0013] According to one embodiment of the present invention, the tangential structure is provided in at least two sets, and may be provided in more than two sets.

[0014] According to one embodiment of the present invention, the operating end of the handle is provided with a gripping part, and the two sides of the gripping part are provided with protruding structures to prevent slippage when gripping and to ensure stability when inserting.

[0015] The beneficial effects of this invention are that, by setting a centrifugal spray nozzle, when the liquid medicine enters, it can be sprayed outward in a rotating manner from the nozzle under the action of the tangential structure and the vortex chamber, forming a mist-like liquid. Compared with the traditional method of spraying liquid medicine in the form of a water column, the mist-like sprayed liquid can cover a larger area, the absorption effect of the liquid medicine is better, ensuring the therapeutic effect, and it is not easy to lose, reducing the waste of liquid medicine. This solution adds a spray channel, which can also be used for spraying treatment during instrument insertion and suction, thereby improving medical efficiency. Attached Figure Description

[0022] The following description is only intended to disclose the present invention so that those skilled in the art can implement it. The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0023] A bronchial tube with spray therapy function, such as Figure 1 It includes an insertion part 2 and a handle operation end 1.

[0024] The insertion part 2 includes a catheter body 24, an instrument channel 21 and a drug spraying channel 22 disposed in the catheter body 24, and a tip seat 25 installed at the end of the catheter body 24.

[0025] This solution retains the instrument channel 21 and adds a drug spraying channel 22, which does not affect the original instrument placement and suction functions of the endoscope. Drug spraying can also be performed during instrument placement and suction, thus improving medical efficiency.

[0026] The instrument channel 21 and the spray channel 22 can be configured in two ways. One way is that the instrument channel 21 and the spray channel 22 are pipes installed in the catheter body 24, that is, the instrument channel 21 and the spray channel 22 are separate pipes that pass through the catheter body 24. The other way is that the instrument channel 21 and the spray channel 22 are channels formed inside the catheter body 24, that is, two channels are directly formed in the catheter body 24.

[0027] In this embodiment, it is preferable to use separate pipes for the instrument channel 21 and the spraying channel 22, which are inserted into the catheter body 24. Figure 3 The tip seat 25 is provided with an instrument channel opening 28 connected to the instrument channel 21 and a spraying port 27 connected to the spraying channel 22. The inner wall of the spraying port 27 is provided with a limiting step 275 for limiting the spraying channel 22, so as to ensure the relative position of the spraying channel 22 and the spraying port 27 during installation.

[0028] like Figure 4 , Figure 5 The spray nozzle 27 includes a swirling chamber 271 and several tangential structures 272 disposed within the swirling chamber 271. The swirling chamber 271 contains a converging channel 273 and a funnel-shaped nozzle 274 connected to the converging channel 273. Figure 5 The overall shape of the vortex chamber 271, from left to right (in the direction of liquid ejection), consists of a converging funnel-shaped channel, a converging channel 273, and an expanding funnel-shaped nozzle 274. A tangential structure 272 is disposed at the converging funnel-shaped channel. In this embodiment, at least two sets of tangential structures 272 are provided, such as... Figure 4 The tangential structure extends spirally in the spraying direction to form a centrifugal spray nozzle 27.

[0029] After the liquid medicine enters the spray nozzle 27, it is introduced into the vortex chamber 271 through the tangential structure 272 and rotates in the vortex chamber 271. Driven by the axial velocity, it is propelled towards the nozzle. When the liquid medicine approaches the nozzle, it is sprayed outward in a rotating manner under the action of the contraction channel 273 and the trumpet-shaped nozzle 274, thus forming a mist liquid. The mist sprayed liquid medicine can cover a large area, the absorption effect of the liquid medicine is good, and it is not easy to lose, thus reducing the waste of liquid medicine.

[0030] Furthermore, the bronchial catheter with spray treatment function also includes a camera module 26, which is mounted on the tip seat 25 to form an electronic bronchial imaging catheter. The power supply line and signal line of the camera module 26 extend through the catheter body 24 to the handle operation end 1, and the image signal of the camera module 26 is output through the image output interface 15.

[0031] The camera module 26 is used to acquire images and also allows medical staff to see the state of the medicine being sprayed on the monitor, making it easier for them to judge the effect.

[0032] The handle operating end 1 is provided with a spray channel inlet 12 connected to the spray channel 22 and a drug delivery port 11 and a suction port 13 connected to the device channel 21. The drug delivery port 11 is used for drug delivery and auxiliary treatment with the micro medical device, and the suction port 13 is used for suction operation.

[0033] The spray channel inlet 12 is equipped with a Luer connector to facilitate the connection between the spray channel inlet 12 and the drug delivery equipment. Connecting the spray channel inlet 12 to the drug delivery equipment that can precisely control the amount of drug can achieve accurate drug delivery.

[0034] The handle operation end 1 is provided with a grip part 14, and the grip part 14 has protruding structures on both sides to prevent slippage when gripping and ensure stability when inserting.

[0035] Preferably, such as Figure 1The spray channel inlet 12, the drug delivery port 11, and the suction port 13 are respectively located at different end face positions of the handle operating end 1. The drug delivery port 11 and the suction port 13 are respectively located at the front and rear sides of the grip part 14, and the spray channel inlet 12 is located at the side of the handle operating end 1. This makes it easy to distinguish and use the device, and avoids interference between the devices.

[0036] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations and modifications.
