Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an integrally molded sputum collector. Background Technology

[0002] A fiberoptic bronchoscope, also known as a bronchoscope, is an endoscopic device used to observe and treat respiratory tract diseases. It can enter the lobes, segments, and subsegments of the bronchi to directly observe lesions, and can also perform biopsies to help detect early lesions and conduct bacteriological and cytological examinations. In clinical practice, medical personnel usually equip their bronchoscopes with suction devices for aspiration and sputum collectors for collecting sputum.

[0003] However, in current clinical practice, suction and sputum collection are performed separately. When suction is required, the suction device must be connected first, and then suction treatment can begin. If sputum needs to be collected during suction, the suction device must be disconnected from the bronchoscope's suction port, and then the sputum collector must be connected to the bronchoscope's suction port. After collecting the sputum, the sputum collector must be removed, and the suction device must be reconnected to the bronchoscope's suction port. This process is quite cumbersome, which undoubtedly increases the duration of the surgery. Utility Model Content

[0004] This utility model provides an integrally molded sputum collector to solve the aforementioned technical problems.

[0005] The present invention adopts the following technical solution: it includes a collector, a valve assembly, and a drainage tube. The collector has a hollow interior for collecting sputum samples. The valve assembly is located above the top of the collector. The front end of the valve assembly is connected to a first suction tube, and the end of the valve assembly is connected to a second suction tube. The drainage tube is located between the collector and the valve assembly, and the collector and the valve assembly are connected through the drainage tube.

[0006] Preferably, the valve body assembly includes a first valve body and a second valve body, both of which are three-way valve bodies. The front end of the first valve body is connected to the end of the first suction tube, the front end of the second valve body is connected to the end of the first valve body, the end of the second valve body is connected to the end of the second suction tube, and the bottom ends of both the first and second valve bodies are connected to the drainage fitting. Through the cooperation of the first valve body, the second valve body, the first suction tube, the second suction tube, and the drainage fitting, the collector, the suction device, and the bronchoscope can be connected.

[0007] Preferably, the drainage fitting 3 consists of a collection tube and a negative pressure tube. The diameters of the collection tube and the negative pressure tube are adapted to the size of the connecting end on the three-way valve body used by the first valve body and the second valve body. The same end of the collection tube and the negative pressure tube pass through the top of the collector and connect to the cavity of the collector. The other end of the collection tube is connected to the bottom of the first valve body, and the other end of the negative pressure tube is connected to the bottom of the second valve body. Through the cooperation of the collection tube and the negative pressure tube, the collector can be connected to the bronchoscope and the suction device respectively.

[0008] Preferably, the collector includes a bottle body and a cap. The bottle body is a transparent glass container with an open top. The cap fits over the opening of the bottle body, with its inner wall tightly against the outer side of the opening. The top of the cap has two insertion holes for inserting a collection tube and a negative pressure tube. The transparent glass bottle body allows medical personnel to monitor the volume of sputum inside at any time, and the cap seals the opening of the bottle body.

[0009] Preferably, a flexible sealing ring is provided in each of the two insertion holes at the top of the bottle cap. The outer side of the flexible sealing ring is fixedly connected to the inner side of the insertion hole. The flexible sealing rings in the two insertion holes compress the outer walls of the collection tube and the negative pressure tube inserted into the two insertion holes, thereby enhancing the sealing between the collection tube and the negative pressure tube and the corresponding insertion hole.

[0010] Preferably, an elastic sealing tube is fitted over the connection between the bottom of the first valve body and the collecting pipe to prevent leakage between the collecting pipe and the first valve body.

[0011] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0012] The cooperation between the valve assembly and drainage tube of this application allows for real-time adjustment of the communication status between the collector and the suction device and the bronchoscope. Furthermore, it eliminates the need for re-sampling after the suction device has collected sputum. Sputum can be sampled during bronchoscope operation using the negative pressure collector created by the suction device. This allows for the examination of sputum samples collected separately from the suction device, eliminating the need to retrieve sputum samples from the collection component of the suction device. This reduces operational steps and provides convenience for medical personnel during surgical procedures. Attached Figure Description

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] This utility model provides an integrally molded sputum collector, including a collector 1 for collecting sputum specimens, a drainage tube 3, and a valve assembly 2. The collector 1 has a hollow interior. The valve assembly 2 is located above the top of the collector 1. The front end of the valve assembly 2 is connected to a first suction tube 4, and the end of the valve assembly 2 is connected to a second suction tube 5. The drainage tube 3 is located between the collector 1 and the valve assembly 2, and the collector 1 and the valve assembly 2 can be connected through the drainage tube 3.

[0025] The valve body assembly 2 includes a first valve body 21 and a second valve body 22. Both the first valve body 21 and the second valve body 22 are three-way valve bodies. The front end of the first valve body 21 is connected to the end of the first suction tube 4. The front end of the second valve body 22 is connected to the end of the first valve body 21. The end of the second valve body 22 is connected to the end of the second suction tube 5. The bottom ends of both the first valve body 21 and the second valve body 22 are connected to the drainage tube 3.

[0026] The drainage fitting 3 consists of a collection pipe 31 and a negative pressure pipe 32. The diameters of the collection pipe 31 and the negative pressure pipe 32 are adapted to the size of the connecting end on the three-way valve body used by the first valve body 21 and the second valve body 22. The same end of the collection pipe 31 and the negative pressure pipe 32 pass through the top of the collector 1 and connect to the cavity of the collector 1. The other end of the collection pipe 31 is connected to the bottom connecting end of the first valve body 21, and the other end of the negative pressure pipe 32 is connected to the bottom connecting part of the second valve body 22.

[0027] Before using the bronchoscope, the medical personnel first connect the two ends of the first suction tube 4 to the suction port of the bronchoscope and the front end of the first valve body 21, respectively, so that the suction port of the bronchoscope and the front end of the first valve body 21 are connected. Then, the two ends of the second suction tube 5 are connected to the end of the second valve body 22 and the working port of the external suction device, respectively, so that the second valve body 22 and the external suction device are connected. Then, the medical personnel connect one end of the drainage tube 3 to the inner cavity of the collector 1, and the other end of the drainage tube 3 to the bottom of the first valve body 21 and the second valve body 22, so that the drainage tube 3 can be connected to the first suction tube 4 and the second suction tube 5, which are respectively connected to the first valve body 21 and the second valve body 22. This device enables the bronchoscope, the collector and the suction device to be connected.

[0028] Secondly, medical personnel can first operate the first valve body 21 to close the connection between the first suction tube 4 and the front end of the first valve body 21, and at the same time close the connection between the collection tube 31 and the first valve body 21. Then, open the end of the second valve body 22 to connect the suction device with the negative pressure tube 32. Then, start the suction device. At this time, the suction device will draw out the airflow in the negative pressure tube 32. Since the negative pressure tube 32 is connected to the inner cavity of the collector 1, the suction device will also draw out the air in the inner cavity of the collector 1. Then close the connection between the negative pressure tube 32 and the suction device. At this time, the negative pressure tube 32 and the collector 1 are in a negative pressure state so that when the entire device needs to collect sputum samples during use;

[0029] Close the connection between the second valve body 22 and the second suction tube 5, and then adjust the valve on the first valve body 21 to gradually form a connection between the first suction tube 4 and the collection tube 31. The collector 1, which is in a negative pressure state, can slowly draw sputum into the first suction tube 4 through the fiberoptic bronchoscope, and then guide it into the collector 1 through the collection tube 31, thus completing the collection of sputum specimens.

[0030] When suction is required, medical personnel close the connection between the drainage tube 3 and the first valve body 21 and the second valve body 22 by operating the first valve body 21 and the second valve body 22, thereby closing the connection between the collector 1 used to collect sputum specimens and the bronchoscope. At the same time, the first suction tube 4, the first valve body 21, the second valve body 22, the second suction tube 5 and the suction device are connected, so that the suction device is directly connected to the suction connection port of the bronchoscope. When the suction device is started, the bronchoscope is in suction working state.

[0031] Through the cooperation between the valve body assembly 2 and the drainage tube 3 of this application, the communication state between the collector 1 and the suction device and the bronchoscope can be adjusted at any time. Moreover, there is no need to take a sample again after the suction device has collected the sputum. During the operation of the bronchoscope, the sputum can be sampled through the collector 1 under the negative pressure state formed by the suction device. The sputum sample collected separately in the collector 1 can then be tested without having to obtain the sputum sample from the collection component in the suction device. This reduces the number of operation steps and provides convenience for medical personnel in surgical operations.

[0032] In a further embodiment, the collector 1 includes a bottle body 11 and a bottle cap 12. The top of the bottle body 11 is open. The bottle cap 12 is fitted onto the opening of the bottle body 11. The inner sidewall of the bottle cap 12 is in close contact with the outer sidewall of the opening of the bottle body 11. The top of the bottle cap 12 is provided with two insertion holes 121 for inserting the collection tube 31 and the negative pressure tube 32.

[0033] When collecting sputum, the bottle body 11 is a transparent glass container, allowing medical personnel to observe the sputum volume through it and collect the required amount. The top opening of the bottle body 11 is sealed by the bottle cap 12. Two insertion holes 121 are provided on the top of the bottle cap 12, allowing the same end of the collection tube 31 and the negative pressure tube 32 to be inserted into the two corresponding insertion holes 121, communicating with the inside of the bottle body 11. After collecting the specified amount of sputum inside the bottle body 11, the communication between the first valve body 21 and the collection tube 31 is closed, and the communication between the second valve body 22 and the negative pressure tube 32 is also closed. At this point, the medical personnel can directly pull out the collection tube 31 and the negative pressure tube 32 from the insertion holes 121 on the bottle cap 12, and then remove the collector 1 consisting of the bottle body 11 and the bottle cap 12 and send it to the designated location for sputum examination.

[0034] In a further embodiment, a flexible sealing ring 13 is provided in each of the two insertion holes 121 at the top of the bottle cap 12, and the outer side of the flexible sealing ring 13 is fixedly connected to the inner side of the insertion hole 121.

[0035] When one end of the collection tube 31 and the negative pressure tube 32 is inserted into the two corresponding insertion holes 121 on the top of the bottle cap 12, it will pass through the middle of the corresponding flexible sealing rings 13 in the two insertion holes 121 towards the inside of the bottle body 11. The flexible sealing rings 13 in the two insertion holes 121 can squeeze the outer walls of the collection tube 31 and the negative pressure tube 32 inserted into the two insertion holes 121. At this time, the inner sidewall of the flexible sealing ring in the two insertion holes 121 will be tightly fitted with the outer wall of the corresponding collection tube 31 and the negative pressure tube 32, thereby making the connection between the bottle cap 12 and the collection tube 31 and the negative pressure tube 32 more secure and enhancing the sealing between the collection tube 31 and the negative pressure tube 32 and the corresponding insertion hole 121.

[0036] In a further embodiment, an elastic sealing tube 6 is provided on the outside of the connection between the bottom of the first valve body 21 and the collection tube 31. After the collection tube 31 is connected to the bottom of the first valve body 21, the sealing tube 6 can be sleeved on the outside of the collection tube 31 from the other end of the collection tube 31. Then, the sealing tube 6 sleeved on the outside of the collection tube 31 is moved to the connection between the collection tube 31 and the first valve body 21. Since the sealing tube 6 is elastic, after the sealing tube 6 is moved to the designated position, the inner wall of the sealing tube 6 will press tightly against the outer wall of the connection between the collection tube 31 and the first valve body 21, thereby preventing leakage between the collection tube 31 and the first valve body 21.

[0037] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
