Description

Technical Field

[0001] The utility model belongs to the technical field of bronchoscopic examination, and in particular relates to a bronchoscopic examination liquid extraction and sampling device. Background Art

[0002] A bronchoscope is a medical testing device that mainly includes a flexible bronchoscope and a sampling device for biopsy sampling. During operation, the bronchoscope passes through the patient's nasal cavity and respiratory tract to reach the bronchi and other parts.

[0003] During the bronchoscopic examination, the bronchoscope needs to enter different branches of the patient's bronchi. When encountering diseased bronchial tissue, cleaning fluid is pumped into the patient's bronchi through the hose on the bronchoscope. After cleaning, the cleaning fluid is sucked out into a container and sent for inspection as a sample.

[0004] However, in actual work, it was found that the degree of bronchial lesions in patients was different, resulting in different degrees of lesions in different side branches of their bronchial bifurcations. During the sampling process, bronchial branches with different lesions need to be sampled separately. Therefore, during the sampling process, the staff needs to constantly replace the sampling container. Specifically, after pulling out the negative pressure pipe on the sampling container, it is connected to the hose on the bronchoscope. Obviously, this method is not only cumbersome, but also requires constant operation to replace the container during the operation, which not only increases the operation time, but also easily causes the cleaning fluid to leak during the replacement process, resulting in contamination of the operating room.

[0005] At the same time, frequent replacement of containers and repeated opening of negative pressure equipment can easily lead to interruption of the life of negative pressure equipment such as negative pressure pumps.

[0006] Therefore, during the operation, how to achieve fast and easy sampling of bronchi with different bronchial branches, different degrees of infection, and different pathological conditions during bronchoscopy is of great significance for reducing operation time, improving operation efficiency, and reducing patient discomfort.

[0007] Based on the above background, the purpose of the utility model is to provide a bronchoscopic liquid sampling device.

[0008] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0046] Example 1

[0047] like Figure 1-6As shown, a bronchoscopic fluid extraction sampling device includes a ring center frame 1 (the ring center frame 1 is made of plastic material, and its inner radius is: 25 cm). A plurality of sampling mechanisms are slidably assembled and connected to the above-mentioned ring center frame 1. Specifically, the sampling mechanism includes a long spring 22 (the material of the long spring 22 is a spring of elastic plastic material, and its purpose is to be able to be easily stretched). The outer end of the long spring 22 is fixedly assembled and connected with a spring seat 221; the spring seat 221 is rotatably connected with a suction sampling component 23, and the suction sampling component 23 includes a mounting end plate 231. The specific rotation method is: a limited rotation shaft is fixedly connected to the spring seat 221, and a limited seat 2311 is fixedly connected to the mounting end plate 231, and the limited rotation shaft is rotatably connected in the limited seat 2311. Specifically, the method of limiting the rotation of the limiting shaft and the limiting seat 2311 is a conventional method disclosed in the prior art, which specifically adopts that the end of the limiting shaft is fixedly connected with a blocking seat, and an annular groove is opened in the cylindrical groove body of the limiting seat 2311 which is rotatably connected to the limiting shaft, and the blocking seat rotates and blocks in the annular groove.

[0048] The angle adjustment of the mounting end plate 231 is facilitated by adopting a rotating connection method. Two symmetrically arranged aspiration needle tubes 232 are assembled and connected to the mounting end plate 231; the aspiration needle tube 232 is a conventional syringe needle tube disclosed in the prior art, and its main structure includes a needle tube part and a piston located in the needle tube part, and a needle handle that pulls the piston. In order to facilitate the subsequent replacement of the aspiration needle tube 232, the two sides of the mounting end plate 231 are respectively provided with assembly through holes; the assembly through holes are lined with an elastic extrusion rubber pad 2312. The aspiration needle tube 232 elastically contacts the elastic extrusion rubber pad 2312.

[0049] This method facilitates the positioning of the suction needle tube 232 and the removal of the suction needle tube 232 for replacement. During positioning, the suction needle tube 232 is kept different under the extrusion of the elastic extrusion rubber pad 2312.

[0050] During the working process, the operator marks the mounting end plate 231 in advance. When sampling, the operator connects the suction needle tube 232 to the negative pressure suction tube on the bronchoscope, pulls the needle handle on the suction needle tube 232 to pump the cleaning fluid (the cleaning fluid contains the diseased tissue of the patient to be cleaned) pumped into the bronchus by the bronchoscope, and extracts and stores it on the suction needle tube 232. During the entire operation, when the device is used to achieve sampling, there is no need to replace the container midway. When the bronchoscope is at different branch positions of the patient's bronchus, sampling can be performed after cleaning. This method can achieve high flexibility and easy operation of sampling the patient's bronchi, thereby achieving classified sampling of branch bronchioles with different degrees of lesions in the patient's bronchus, thereby improving detection efficiency.

[0051] Specifically, during the operation, the staff pulls the installation end plate 231, at which time the spring is easily stretched and the suction needle tube 232 is connected.

[0052] In the actual working process, the cleaning liquid after the patient's bronchial cleaning is still stored in a large container. Therefore, in order to facilitate the extraction and sampling, the cleaning liquid is placed in a container for storage. According to the existing method, a Y-shaped bifurcated pipeline is connected to the hose of the bronchoscope, and a valve is installed at each bifurcated end. During the working process, the suction needle 232 is connected to a bifurcation of the Y-shaped bifurcated pipeline (the other bifurcation point is directly connected to the container storing the cleaning liquid), and the valve is opened (the other valve is closed) for sampling. After sampling, the valve is closed and the other valve is opened, and the cleaning liquid remaining in the patient's trachea enters the container (in the prior art, the container storing the cleaning liquid forms a negative pressure through a negative pressure pump for sucking the cleaning liquid).

[0053] In this way, the sampling can be separated and the frequent replacement of the container can be avoided. During operation, the cleaning liquid after sampling is directly mixed and put into the container as waste liquid.

[0054] Example 2

[0055] like Figure 1-6 As shown, based on the structure of Example 1, this embodiment has a plurality of arc-shaped slides 21 slidably connected to the ring center frame 1, and a locking screw 211 is threadedly connected to the inner wall of the arc-shaped slide 21; after the arc-shaped slide 21 is slidably adjusted, the arc-shaped slide 21 is squeezed and positioned by the locking screw 211.

[0056] The purpose of using the arc-shaped slide seat 21-locking screw 211 is to facilitate the adjustment of the position of the mounting end plate 231-suction needle tube 232 at different positions on the ring center frame 1, and ensure that during operation, the mounting end plate 231-suction needle tube 232 at different positions can be operated in the most convenient posture and position.

[0057] Example 3

[0058] like Figure 1-6 As shown, this embodiment is based on the structure of the embodiment 2. Similarly, for the convenience of operation, an angle adjustment member is fixedly connected to the outer wall of the arc-shaped slide seat 21; the long spring 22 is fixedly connected to the angle adjustment member. Through the angle adjustment member, a relatively flexible pulling state is maintained during the process of pulling the long spring 22, ensuring the flexibility of the installation end plate 231-suction needle tube 232, which is convenient for operation.

[0059] Specifically, the angle adjustment member includes a fixed seat 222 fixedly connected to the arc-shaped slide seat 21 , and a hinged ball 2221 is hinged on the fixed seat 222 (the fixed seat 222-hinged ball is a spherical hinge), and the long spring 22 is fixedly connected to the hinged ball 2221 .

[0060] During the pulling process of the long spring 22, the articulated ball is continuously deflected relative to the fixing seat 222, thereby matching the pulling angle of the spring.

[0061] Example 4

[0062] like Figure 1-6 As shown, in this embodiment, based on the structure of embodiment 3, a central connecting plate 3 is fixedly connected to the central portion of the ring center frame 1; and the sampling mechanisms are symmetrically distributed on both sides of the ring center frame 1 with the central connecting plate 3 as the symmetry center.

[0063] Therefore, during the adjustment process, the sampling mechanisms on both sides are adjusted separately with the central connecting plate 3 as the boundary.

[0064] Meanwhile, a through hole structure is provided at the center of the center connecting plate 3 ; an elastic rubber sleeve 31 is fixedly connected to the center of the top of the center connecting plate 3 ; and the elastic rubber sleeve 31 is located at the top of the through hole structure.

[0065] The purpose of the specific design of the elastic rubber sleeve is to facilitate the positioning of the entire device during operation. For example, for the convenience of operation, the operator can put the elastic rubber sleeve on the support rod in the operating room. Or during use, the elastic rubber sleeve is directly opened, and the operator's arm is inserted deep. Through the elastic squeezing of the elastic rubber sleeve, the entire device can be carried on the staff's arm. After sampling, the entire device is withdrawn, and the sample solution in the different suction needle tubes 232 is injected into the detection sample tube, such as a test tube, to facilitate subsequent testing.

[0066] When using the entire device, the operator only needs to stand next to the bronchoscope during the operation. The entire operation only requires the operator to cooperate with the bronchoscope inspection and take samples, without the need to frequently move the position or frequently change the container carrying the sample.

[0067] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
