Abstract
Description
Technical Field
[0001] This application relates to the field of bronchoscope technology, specifically to an auxiliary accessory for a disposable bronchoscope without a drug delivery port. Background Technology
[0002] In respiratory clinical practice, bronchoscopy is an extremely common procedure. Traditionally, bronchoscopy is mainly used repeatedly in clinical practice. However, due to the complex internal structure and high degree of system integration, traditional bronchoscopy is difficult to sterilize after use. Moreover, related studies have found that reusable bronchoscopy still poses a risk of contamination after cleaning. Therefore, disposable bronchoscopy products have emerged to meet the bronchoscopy needs of patients with infectious diseases, such as hepatitis B patients.
[0003] In related technologies, some disposable fiberoptic bronchoscopes do not have an administration port. In actual clinical practice, for patients with a history of hepatitis B who have a lot of sputum, a disposable fiberoptic bronchoscope is used for examination and sampling. During this process, if the patient has a strong airway reaction or airway bleeding, the doctor will usually instruct the nurse to administer medication into the airway. In this case, the current procedure is to disconnect the tubing connected to the operation port before administering the medication. Disconnecting the tubing multiple times increases the risk of sputum sample contamination and is also cumbersome for nurses. Utility Model Content
[0004] To at least partially overcome the problems existing in the related technologies, this application provides an auxiliary accessory for a disposable bronchoscope without a drug delivery port. Based on the application of this auxiliary accessory in various scenarios, the risk of sputum sample contamination is reduced, and the actual operation of nurses is facilitated.
[0005] This application provides an auxiliary accessory for a disposable bronchoscope without a drug delivery port. The auxiliary accessory includes a sputum collector, which includes a collector bottle and a bottle sealing cap. The bottle sealing cap is provided with a negative pressure suction tube and a suction tube that communicate with the inside of the collector bottle.
[0006] It also includes a three-way valve assembly, the first port of which is connected to the operating channel of the bronchoscope, the second port of which is connected to the end of the suction tube away from the collector bottle, and the third port of which is used as a drug delivery port.
[0007] In one possible implementation, the three-way valve assembly is based on a medical three-way valve; the valve housing of the three-way valve assembly is provided with a blocking structure for limiting the rotation angle of the valve handle, so as to prevent the valve handle from rotating to an angle that connects the second port and the third port.
[0008] In one possible implementation, the blocking structure consists of limiting posts respectively disposed near the second and third ports, the axial directions of the two limiting posts being perpendicular to the virtual plane determined by the pointing rod of the valve handle, and the height of the limiting posts being higher than the virtual plane.
[0009] In one possible implementation, a removable protective cap is also provided on the third port of the three-way valve assembly.
[0010] In one possible implementation, the third port is further provided with an internal thread that mates with the helical interface of the drug delivery syringe.
[0011] One possible implementation also includes a main connecting tube for connecting the first port to the operating channel port of the bronchoscope.
[0012] In one possible implementation, the end of the negative pressure suction tube away from the collector bottle is also provided with a connecting joint.
[0013] In one possible implementation, the suction tube is detachably connected to the second port.
[0014] In one possible implementation, the first, second, and third ports are designed to have different diameters.
[0015] One possible implementation also includes a fixing support device for securing the sputum collector.
[0016] The auxiliary accessories for a disposable bronchoscope without a drug delivery port provided in this application include a sputum collector, which comprises a collector bottle and a bottle sealing cap. The bottle sealing cap is provided with a negative pressure suction tube and a suction tube communicating with the inside of the collector bottle. It also includes a three-way valve assembly. The first port of the three-way valve assembly is used to connect to the operating channel of the bronchoscope, the second port is connected to the end of the suction tube away from the collector bottle, and the third port serves as a drug delivery port. In this auxiliary accessory, a three-way valve assembly is provided on the suction tube of the sputum collector. The other two ports of the three-way valve assembly are used to connect to the bronchoscope and serve as a drug delivery port, respectively. In the application described in the background art, drug delivery does not require disconnecting from the bronchoscope; the three-way valve assembly is used to switch the guiding branch, effectively reducing the risk of sputum sample contamination and improving the convenience of operation for nurses.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] As described in the background section, bronchoscopy is an extremely common procedure in respiratory clinical practice. Traditionally, bronchoscopy is mainly used repeatedly in clinical practice. However, due to the complex internal structure and high degree of system integration, traditional bronchoscopy is difficult to sterilize after use. Moreover, related studies have found that reusable bronchoscopy still poses a risk of contamination after cleaning. Therefore, disposable bronchoscopy products have emerged to meet the bronchoscopy needs of patients with infectious diseases, such as hepatitis B patients.
[0029] In related technologies, some disposable fiberoptic bronchoscopes do not have an administration port. In actual clinical practice, for patients with a history of hepatitis B who have a lot of sputum, a disposable fiberoptic bronchoscope is used for examination and sampling. During this process, if the patient has a strong airway reaction or airway bleeding, the doctor will usually instruct the nurse to administer medication into the airway. In this case, the current procedure is to disconnect the tubing connected to the operating channel before administering the medication. Disconnecting the device multiple times increases the risk of sputum sample contamination and is also cumbersome for nurses.
[0030] Based on this, this application proposes an auxiliary accessory for a disposable bronchoscope without a drug delivery port. The application of this auxiliary accessory in various scenarios reduces the risk of sputum sample contamination and facilitates the actual operation of nurses.
[0031] like Figure 1 As shown, in one embodiment, the auxiliary accessory proposed in this application includes a sputum collector 10, which includes a collector bottle 11 and a bottle sealing cap 12. The bottle sealing cap 12 is provided with a negative pressure suction tube 20 and a suction tube 30 that communicate with the inside of the collector bottle.
[0032] It also includes a three-way valve assembly 40. The first port of the three-way valve assembly 40 is used to connect to the operating port of the bronchoscope. For example, it can be connected to the operating port of the bronchoscope via a main connecting tube 50. That is, it also includes a main connecting tube 50 for connecting the first port to the operating port of the bronchoscope. The second port of the three-way valve assembly is connected to the end of the suction catheter away from the collector bottle 11. The third port of the three-way valve assembly is used as a drug delivery port. Figure 1 The upward-facing port of the three-way valve assembly is used as the drug delivery port.
[0033] In practical applications, the auxiliary accessories described above are configured such that the first port of the three-way valve assembly connects to the operating channel of the bronchoscope, the negative pressure suction tube connects to the negative pressure, and the on / off state of the three-way valve assembly is adjusted to connect the first port to the second port for sputum suction. When medication is required, the on / off state of the three-way valve assembly is adjusted to connect the first port to the third port, and medication is administered through the third port. Thus, when using a disposable bronchoscope without a medication port for relevant testing and sampling, compared to existing technologies, this auxiliary accessory eliminates the need to disconnect the bronchoscope during medication administration; simply switching the flow path via the three-way valve assembly effectively reduces the risk of sputum sample contamination and improves operational convenience for nurses.
[0034] It should be noted that the three-way valve assembly here can adopt a structure similar to existing medical three-way valves. As is known to those skilled in the art, a medical three-way valve structure includes a valve housing and a valve core. The valve housing has three cavity interfaces that communicate with the outside, making the valve housing T-shaped. The valve core is cylindrical and has three through holes that communicate with the valve housing, and these three through holes are T-shaped. The valve core also has a valve handle that can drive the valve core to rotate. The valve handle has three pointing rods that correspond one-to-one with the three through holes on the valve core (e.g., ...). Figure 2 , Figure 3 (See the arrow illustration in the diagram). When using a medical three-way valve, the switching of the conductive branch can be achieved by adjusting the rotation angle of the valve handle.
[0035] In the technical scenario of this application, if the second port and the third port are connected when switching the conduction branch, it is easy to cause contamination of the sputum sample. Therefore, if the existing medical three-way valve structure is used to implement the three-way valve component in this application, the relevant operators need to pay attention to the operation when using the auxiliary accessories to avoid switching errors.
[0036] Therefore, further, to prevent switching errors caused by operator negligence, such as Figure 2 As shown, in a preferred embodiment, the three-way valve assembly 40 in this application is based on a medical three-way valve, that is, the three-way valve assembly 40 also includes a valve housing 41 and a valve handle 42. On this basis, the valve housing 40 of the three-way valve assembly is provided with a blocking structure 43 for limiting the rotation angle of the valve handle 42, so as to prevent the valve handle 43 from rotating to the angle that connects the second port and the third port.
[0037] Furthermore, considerations regarding implementation costs arise, as a specific implementation method, such as Figure 2 As shown, the blocking structure 43 consists of limiting posts located near the second and third ports, respectively. The axial directions of the two limiting posts are perpendicular to the virtual plane determined by the guide rod of the valve handle, and the height of the limiting posts is higher than this virtual plane, meaning the limiting posts extend beyond the virtual plane. A three-way valve assembly with this structure can only achieve... Figure 2 and Figure 3 The connected state shown can prevent the occurrence of a second port ( Figure 2 (middle left side) and the third side ( Figure 2 The occurrence of the connection between the upper and middle sides means that, in actual implementation, the limiting post here can be manufactured by integrally molding it with the valve shell.
[0038] Based on the above embodiments, in some embodiments, to prevent the third port from being contaminated when not in use, a removable protective cap is also provided on the third port of the three-way valve assembly 40, which is not shown in the figure.
[0039] Based on the above embodiments, in some embodiments, in actual scenarios, drug administration is carried out through a drug delivery syringe with a helical interface. Accordingly, the third port of the three-way valve assembly 40 is also provided with an internal thread that mates with the helical interface of the drug delivery syringe.
[0040] Based on the above embodiments, in some embodiments, such as Figure 1 As shown, in order to facilitate the connection of negative pressure during use, a connecting connector 21 is provided at the end of the negative pressure suction tube 20 away from the collector bottle 11. The connecting connector 21 and the negative pressure suction tube 20 are either integrally connected or detachably connected.
[0041] Based on the above embodiments, in some embodiments, the suction tube 30 and the second port are detachably connected to facilitate flexible application in practice. In this case, when the auxiliary accessories are used, the connection and assembly of the accessories themselves may be incorrect.
[0042] Therefore, the first, second, and third ports of the three-way valve assembly are designed with different diameters, and the corresponding pipelines also use corresponding matching pipe diameters to avoid connection and assembly errors.
[0043] Based on the above embodiments, in some embodiments, for ease of practical use, similar to existing related products, the auxiliary accessories also include a fixing support device for fixing the sputum collector, which is not shown in the figure.
[0044] Based on the above description of the embodiments, it is obvious that the auxiliary accessory of this application has the following advantages: when applied in the scenarios in the background art and similar implementation scenarios, the risk of sputum contamination caused by repeated disconnection from the bronchoscope can be effectively reduced, and the workload of nurses can also be significantly reduced.
[0045] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
