Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to an auxiliary water delivery device for medical ultrasound endoscopy. Background Technology

[0002] Endoscopic ultrasound (EUS) is a digestive tract examination technique that combines endoscopy and ultrasound. A miniature high-frequency ultrasound probe is placed at the tip of the endoscope. After the endoscope is inserted into the body cavity, while directly observing lesions of the digestive tract mucosa, real-time scanning can be performed using ultrasound under endoscopy. This allows for the acquisition of histological features of the layered structure of the gastrointestinal tract and ultrasound images of surrounding organs, thereby further improving the diagnostic level of endoscopy and ultrasound.

[0003] Current endoscopic auxiliary water delivery devices all require a water pump to generate negative pressure and draw water out, which is then delivered to the endoscope via a flexible tube. However, the pump structure inevitably experiences some amplitude and vibration during operation, leading to overall structural instability and potential leaks at pipe connections. Furthermore, the pipes need to be replaced after a certain period of use to prevent damage. Existing technologies lack convenient installation and disassembly functions for the pipes, affecting work efficiency. To address these issues, this paper provides an auxiliary water delivery device for medical ultrasound endoscopy. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an auxiliary water delivery device for medical ultrasound endoscopy, which aims to improve the existing technology's lack of protection against the amplitude effects generated by the pump structure and the lack of quick disassembly of the pipeline.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an auxiliary water delivery device for medical ultrasound endoscopy, comprising a fixed frame, a shell being provided through the surface of the fixed frame, a U-shaped frame being fixedly installed on the top surface of the fixed frame by external screws, telescopic mechanisms being provided on both sides of the U-shaped frame, a miniature water pump being provided inside the shell, a water inlet being connected to one end of the miniature water pump, and a positioning mechanism being provided through the inside of the water inlet.

[0006] As a further description of the above technical solution:

[0007] The telescopic mechanism includes a knob, the outer surface of which is provided with a threaded locking element, and the knob is abutted and limited by the threaded locking element against the U-shaped frame. The inner side of the knob is connected to a threaded sleeve through the U-shaped frame. The threaded sleeve has a threaded rod that is helically driven inside. The outer surface of the threaded rod is fitted with a rotating shaft, and the threaded rod is connected to a reinforcing mechanism through the rotating shaft.

[0008] As a further description of the above technical solution:

[0009] The reinforcement mechanism includes a base plate, on one side surface of which a buffer spring is fixedly installed. One end of the buffer spring is connected to an arc plate, and the inner side of the arc plate is pressed against the outer shell.

[0010] As a further description of the above technical solution:

[0011] The positioning mechanism includes a sleeve, a spring rod is provided through the surface of the sleeve, a water inlet connecting block is sleeved on one side of the water inlet, an insertion rod is connected to one end of the spring rod that passes through the sleeve, the insertion rod is inserted through the water inlet connecting block, and a leak-proof pad is added at the connection between the insertion rod and the water inlet connecting block.

[0012] As a further description of the above technical solution:

[0013] The water inlet connector is fitted with a water delivery hose inside, and one end of the water delivery hose is connected to a nozzle.

[0014] As a further description of the above technical solution:

[0015] The outer shell has a bottom compartment installed at one end, and a water storage tank is connected to one end of the bottom compartment. The outer shell is made of transparent panel material, and a scale is provided on the surface of the outer shell. The outer surface of the water storage tank is attached to the inner surface of the outer shell.

[0016] This utility model has the following beneficial effects:

[0017] In this utility model, the telescopic mechanism can be used to drive the reinforcement mechanism to adapt and adjust according to the size of different shell structures. The reinforcement mechanism can limit and abut the two sides of the shell under the stable support of the buffer spring and the base plate, thereby effectively reducing the impact of the amplitude sway generated when the water pump is working on the overall equipment. The positioning mechanism can be used to quickly disassemble the water supply hose. The water supply hose is inserted into the water inlet through the water inlet connection block. The insertion rod is inserted through the water inlet connection block by the force provided by the spring rod and extends out of the water inlet. When disassembly is required, the pipe can be quickly disassembled by manually pulling the spring rod. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4 An embodiment of this utility model provides an auxiliary water delivery device for medical ultrasound endoscopy, including a fixed frame 1, a housing 2 extending through the surface of the fixed frame 1, a U-shaped frame 3 fixedly mounted on the top surface of the fixed frame 1 by external screws, telescopic mechanisms 4 provided on both sides of the U-shaped frame 3, a miniature water pump 5 provided inside the housing 2, a water inlet 6 connected to one end of the miniature water pump 5, and a positioning mechanism 7 extending through the inside of the water inlet 6;

[0026] The telescopic mechanism 4 includes a knob 401. A threaded locking element is provided through the outer surface of the knob 401, and the knob 401 abuts against and limits the U-shaped frame 3 through the threaded locking element. A threaded sleeve 402 is connected through the U-shaped frame 3 to the inner side of the knob 401. A threaded rod 403 is screwed inside the threaded sleeve 402. A rotating shaft is sleeved on the outer surface of the threaded rod 403, and a reinforcing mechanism 8 is connected to the threaded rod 403 through the rotating shaft 403.

[0027] The reinforcement mechanism 8 includes a base plate 801. A buffer spring 802 is fixedly installed on one side surface of the base plate 801. One end of the buffer spring 802 is connected to an arc plate 803. The inner side of the arc plate 803 is pressed and connected to the outer shell 2.

[0028] The positioning mechanism 7 includes a sleeve 701, with a spring rod 702 extending through its surface. A water inlet connecting block 10 is fitted onto one side of the water inlet 6. One end of the spring rod 702, which extends through the sleeve 701, is connected to an insertion rod 703. The insertion rod 703 is inserted into the water inlet connecting block 10. A leak-proof pad is added at the connection between the insertion rod 703 and the water inlet connecting block 10. By connecting the water inlet connecting block 10 to the water inlet hose 11, the water inlet connecting block 10 drives the water inlet hose 11 to be inserted into the water inlet 6. Previously, the extension and contraction tension of the spring rod 702 drove the insertion rod 703 to rise. After the water inlet connecting block 10 is inserted into the water inlet 6, the spring rod 702 is released, which drives the insertion rod 703 to be inserted through, thus completing the fixed installation.

[0029] The water inlet connector 10 is fitted with a water delivery hose 11. One end of the water delivery hose 11 is connected to a nozzle 12. The water delivery to the endoscope is completed through the water delivery hose 11, and the water is sprayed out through the nozzle 12.

[0030] The inner end of the outer shell 2 is equipped with a bottom compartment 13, and one end of the bottom compartment 13 is connected to a water storage tank 14. The outer shell 2 is made of transparent panel material, and a scale is provided on the surface of the outer shell 2. The outer surface of the water storage tank 14 is attached to the inner surface of the outer shell 2. The bottom compartment 13 serves as the connection part between the water storage tank 14 and the external water source. The bottom compartment 13 can be disassembled inside the bottom of the outer shell 2 and taken out for cleaning.

[0031] Working principle: During use, water is supplied to the water storage tank 14 via an external water inlet device connected to the bottom compartment 13 for pre-storage. After inserting the water delivery hose 11 into the water inlet connector 10, the water inlet connector 10 is inserted into the water inlet 6. Previously, the insertion rod 703 was lifted by manually holding the spring rod 702. After the water inlet connector 10 is fully inserted into the water inlet 6, the spring rod 702 is released. The spring tension causes the insertion rod 703 to align with the bottom of the water inlet connector 10 and pass through the water inlet 6. The outer casing 2 features a transparent panel design, allowing for easy monitoring of the required water volume using a scale to ensure a normal water level inside the water storage tank 14. One end of the water delivery hose 11 is connected to the endoscope. The miniature water pump 5 is connected at one end to the water storage tank 14. The miniature water pump 5 transfers water from the water storage tank 14 to the water delivery hose 11 to deliver water to the patient. The vibration generated by the miniature water pump 5 during operation is absorbed by the arc plate 803 and the buffer spring 802. The material properties of the buffer spring 802 reduce the vibration amplitude of the outer shell 2 structure, thereby achieving an overall buffering effect. After use, manually hold the top handle of the spring rod 702 and lift it upwards. The spring rod 702 drives the insertion rod 703 to be pulled out of the water inlet connection block 10. Then, the water inlet connection block 10 can be pulled out of the water inlet 6, completing the convenient replacement of the water delivery hose 11.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
