Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a liquid perfusion device for a soft digestive endoscope. Background Art

[0002] Colonoscopy is the gold standard for detecting early intestinal cancer, and more and more people are beginning to pay attention to colonoscopy. Our large intestine has many folds, which hide feces and intestinal mucus. Usually, when operating a colonoscopy, it is necessary to inflate or inject water into the intestine while inserting the scope, so as to stretch the intestine and facilitate the insertion of the scope and observation. Water injection can also significantly reduce the degree of abdominal pain, especially the pain level of constipated patients during the examination, improve the satisfaction rate, and significantly reduce the probability of auxiliary body position changes and abdominal compression during the examination. At present, the water injection process is achieved by connecting the water injection port of the colonoscope to an external perfusion tube and then connecting to sterile water for injection. However, there is currently no dedicated external perfusion tube in clinical practice, which needs to be connected through multiple pipes. The flow rate cannot be adjusted and it is easy to cause leakage of sterile water, which is not convenient for clinical use. Utility Model Content

The following is a description of the embodiments of the present invention based on its overall structure.

[0022] Example 1

[0023] As shown in the figure, a liquid perfusion device for a digestive soft endoscope includes a colonoscope connecting end, a hose section, a flow regulator, a perfusion tube and a sterile water connecting end; a hose section and a flow regulator are arranged in the middle of the perfusion tube; one end of the perfusion tube is a colonoscope connecting end, and the other end is a sterile water connecting end.

[0024] Next, the working principle of the embodiment is described in detail to enable those skilled in the art to better understand the present invention:

[0025] The enteroscope connection end is connected to the enteroscope to ensure that the liquid can be directly delivered to the lens part of the enteroscope. The hose section and the flow regulator are located in the middle of the perfusion tube. The hose section is connected to the water pump system of the enteroscope. Medical staff can control the liquid flow rate and pressure by turning the regulator wheel on the flow regulator. Through the flow regulator, the amount of perfusion liquid can be accurately controlled to avoid discomfort to the patient. The sterile water connection end is used to connect to a sterile water bottle.

[0026] Example 2

[0027] The difference between this embodiment and embodiment 1 is that the colonoscope connection end is cylindrical. The colonoscope connection end is designed to be cylindrical, which can better fit the interface of the colonoscope and ensure the stability and sealing of the connection.

[0028] The working principle of this embodiment is the same as that of Embodiment 1.

[0029] Example 3

[0030] The difference between this embodiment and embodiment 2 is that the diameter of the hose section matches the pressure pump commonly used in the gastroenteroscope host. The diameter of the hose section matches the pressure pump commonly used in the gastroenteroscope host, so that the perfusion tube can be directly connected to the pumping system of the gastroenteroscope host without the need for other external pipes.

[0031] Example 4

[0032] The difference between this embodiment and embodiment 3 is that the sterile water connection end includes a tee and a sterile water connection assembly; one end of the tee is connected to the perfusion tube, and the other two ends are respectively connected to a sterile water connection assembly.

[0033] The sterile water connection end is provided with a three-way connection so that two sterile water sources can be connected at the same time. When performing sterile water perfusion, medical staff can connect another bottle of sterile water before one bottle of sterile water is exhausted, thereby realizing air-free switching perfusion and improving the safety and comfort of perfusion.

[0034] The working principle of this embodiment is the same as that of Embodiment 1.

[0035] Example 5

[0036] This embodiment is different from Embodiment 4 in that the sterile water connection assembly includes a drip bucket, a bottle insertion needle and a sheath; one end of the drip bucket is connected to a tee, and the other end is equipped with a bottle insertion needle; the outer portion of the bottle insertion needle is covered with a sheath.

[0037] The drip funnel is used to observe and control the inflow of sterile water, the bottle insertion needle is used to insert the sterile water bottle, and the sheath is used to protect the bottle insertion needle and maintain a sterile state.

[0038] The working principle of this embodiment is the same as that of Embodiment 1.

[0039] Example 6

[0040] This embodiment differs from Embodiment 5 in that it further includes a one-way valve; a one-way valve is arranged between the drip bucket and the three-way connection. The one-way valve is arranged between the drip bucket and the three-way connection to ensure that the liquid can only flow in one direction. On the one hand, it can prevent the liquid or gas in the colonoscope from flowing back into the sterile water container, and on the other hand, it can prevent the air from entering the perfusion tube when the sterile water bottle is replaced.

[0041] The working principle of this embodiment is the same as that of Embodiment 1.

[0042] Example 7

[0043] The difference between this embodiment and embodiment 6 is that the length of the tube body of the perfusion tube between the colonoscope connection end and the hose section is greater than 1m. The length of the tube body of the perfusion tube between the colonoscope connection end and the hose section is greater than 1m, which is convenient for the staff to operate the colonoscope and improves the convenience of use.

[0044] The working principle of this embodiment is the same as that of Embodiment 1.

[0045] Example 8

[0046] This embodiment differs from Embodiment 7 in that it further comprises a heating device, which is arranged between the sterile water connection end and the flow regulator. The heating device is a constant temperature water bath, and the perfusion tube is located between the sterile water connection end and the flow regulator, which can be placed in the constant temperature water bath to heat the sterile water and provide a more comfortable colonoscopy process for the patient.

[0047] The working principle of this embodiment is the same as that of Embodiment 1.

[0048] In summary, the utility model arranges a hose section and a flow regulator in the middle of the perfusion tube, so that the perfusion tube is easy to connect with the water pumping system of the colonoscope, and the perfusion flow rate can be adjusted according to the progress of the colonoscopy; in addition, a colonoscope connecting end and a sterile water connecting end are respectively arranged at both ends of the perfusion tube, so that the colonoscope end, the water pumping system and the sterile water connecting part are designed as a whole, which can be used clinically for one-time use and is more in line with infection control requirements.
