Description

Technical Field

[0001] This utility model relates to the technical field of water supply pipe connection devices, and in particular to a water supply pipe connection device used in endoscopes. Background Technology

[0002] Endoscopic water injection, also known as saline infusion, involves injecting water or saline solution into the body during endoscopic procedures. This technique improves the field of vision, allowing doctors to better observe the internal structure of organs. Specifically, the purposes and benefits of endoscopic water injection include: **Purpose:** Clearer Vision: During endoscopic examinations, especially in cavities like the gastrointestinal tract and bladder, internal fluids can obstruct the field of vision. Injecting water flushes away these fluids, ensuring the lens clearly sees the target area and aids in accurate diagnosis. **Maintaining Lumen Expansion:** Water injection helps widen the cavities being examined, reducing pressure. Especially during gastrointestinal examinations, the injection of water makes the lumen more open, allowing doctors to better observe details of the intestinal wall. **Reducing Difficulty in Endoscopic Insertion:** During some endoscopic procedures, cavities may constrict due to patient positioning or muscle tension. Injecting water slightly expands the space within the cavities, reducing discomfort and facilitating smoother endoscope insertion. **Removing Blood Clots, Foreign Bodies, or Residue:** Bleeding or residual foreign bodies may occur during some endoscopic procedures. Injecting water helps to cleanse these areas, allowing doctors to better assess bleeding or the location of foreign bodies. Advantages: Improved visualization: Injecting water effectively removes food debris, blood, or secretions from the lumen, ensuring clearer images and enabling doctors to more accurately examine lesions, improving diagnostic accuracy. Reduced difficulty: Injecting water expands the lumen, reducing insertion difficulties or limited visibility caused by lumen contraction. This is especially beneficial for gastrointestinal examinations, as water effectively reduces obstruction from gas and food debris, making the procedure smoother. Reduced patient discomfort: Endoscopic examinations, especially gastrointestinal ones, can cause discomfort or pain. Injecting water helps reduce dryness in the lumen and prevents excessive gas expansion, thus alleviating patient discomfort. Increased examination efficiency: Clearer vision allows doctors to quickly identify and address problems, reducing the time needed for repeated lens adjustments, thereby increasing examination efficiency and shortening patient examination time. Adjunctive treatment: During endoscopy, injecting water helps cleanse lesion areas, aiding in the management of bleeding, ulcers, and other issues. Furthermore, water can be used for the irrigation or guidance of local medications, enhancing treatment effectiveness. Improving patient safety: Continuous water delivery effectively reduces damage caused by tissue dryness or improper operation during endoscopic examinations, thereby improving patient safety. Endoscopic water delivery plays a crucial role in examinations and treatments. It not only improves visibility and reduces operational difficulty but also enhances patient comfort and examination accuracy. With the continuous advancement of endoscopic technology, water delivery has become an indispensable part of an increasing number of endoscopic examinations and treatments.

[0003] During endoscopic procedures, medical staff need to deliver fluids such as water, saline solution, or lubricants into the patient's body as needed. These fluids need to be changed as the procedure progresses to ensure its smooth operation. However, in current technology, when changing the delivered fluid, medical staff simply disconnect the water inlet connector from the pump connected to the water tank and reinsert it into the pump connected to another fluid tank. This operation creates a vacuum period during fluid delivery, which is detrimental to the endoscopic procedure. Furthermore, during this process, the water inlet connector and part of the inner wall of the water inlet connector come into contact with air. This contact with air poses a risk of infection to the water inlet connector and part of the inner wall of the hose, increasing the risk of infection to the patient during the endoscopic procedure and hindering their recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a connecting water supply tube device for endoscopes, which enables the replacement of fluids delivered into the patient's body in a closed and hygienic environment, thereby reducing the risk of infection to the patient during endoscopic procedures.

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-3 This utility model discloses a water supply pipe connection device for an endoscope, comprising a chamber 1, an inlet pipe 2 fixedly connected to the front of the chamber 1, locking blocks 3 fixedly connected to the four corners inside the inlet pipe 2, a first outlet pipe 4 fixedly connected to the left side of the chamber 1, locking blocks 3 fixedly connected to the four corners inside the first outlet pipe 4, a second outlet pipe 5 fixedly connected to the right side of the chamber 1, the second outlet pipe 5 having an internal thread 6, damping blocks 7 fixedly connected to the four corners inside the chamber 1, the damping blocks 7 corresponding to slots 9, the damping blocks 7 tightly fitting with a water supply block 8, the water supply block 8 fitting against the inner wall of the chamber 1, the water supply block 8 rotatably connected inside the chamber 1, slots 9 being formed at the four lower corners of the water supply block 8, a fixing ring 10 fixedly connected to the front of the water supply block 8, and fixing rings 1 on the left and right sides of the water supply block 8. 0. The fixing ring 10 corresponds to the water inlet pipe 2. The outer diameter of the fixing ring 10 is the same as the inner diameter of the rear end of the water inlet pipe 2. The fixing ring 10 corresponds to the first water outlet pipe 4. The outer diameter of the fixing ring 10 is the same as the inner diameter of the right end of the first water outlet pipe 4. The fixing ring 10 corresponds to the second water outlet pipe 5. The outer diameter of the fixing ring 10 is the same as the inner diameter of the left end of the second water outlet pipe 5. A three-way pipe 11 is opened inside the water delivery block 8. A connecting ring 12 is fixedly connected to the upper middle part of the water delivery block 8. A connecting block 13 is fixedly connected to the front of the connecting ring 12. Connecting blocks 13 are fixedly connected to the left and right sides of the connecting ring 12. An indicator arrow 14 is fixedly connected to the top of the connecting block 13. A top cover 15 is fixedly connected to the top of the chamber 1. The top cover 15 is located above the water delivery block 8 and fits tightly with the water delivery block 8.

[0023] The above structure, by providing a water inlet pipe 2 and fixing locking blocks 3 at the four corners of the water inlet pipe 2, allows medical staff to insert one end of the water delivery hose into the interior of the water inlet pipe 2. The locking blocks 3 abut against the water delivery hose, and the tight contact between the locking blocks 3 and the water delivery hose makes it difficult for the water delivery hose to fall off after it is installed inside the water inlet pipe 2.

[0024] By providing a first water outlet pipe 4, and fixing locking blocks 3 at the four corners of the inside of the first water outlet pipe 4, medical staff can insert the hose connected to the output end of the water pump into the inside of the first water outlet pipe 4.

[0025] By providing a second water outlet pipe 5 with an internal thread 6, medical staff can insert the hose connected to the output end of the pump that supplies other liquids into the second water outlet pipe 5, ensuring a tight connection between the second water outlet pipe 5 and the hose connected to the output end of the pump that supplies other liquids, effectively preventing the second water outlet pipe 5 from becoming detached from the hose connected to the output end of the pump that supplies other liquids.

[0026] By setting a damping block 7, which is an elastic soft block, the operator can rotate the water delivery block 8. After the operator rotates the water delivery block 8, the damping block 7 enters the interior of the slot 9 in another position, thereby achieving the positioning of the water delivery block 8 after rotation.

[0027] By ensuring that the outer diameter of the retaining ring 10 is the same as the inner diameter of the rear end of the water inlet pipe 2, a portion of the front end of the retaining ring 10 enters the rear end of the water inlet pipe 2 when the device is stationary and the damping block 7 is inserted into the slot 9, preventing water leakage during water delivery. Furthermore, the retaining ring 10 is an elastic soft ring, preventing it from locking the water delivery block 8 during rotation due to the front end of the retaining ring 10 entering the water inlet pipe 2, and the damping block 7 also does not lock the rotation of the retaining ring 10.

[0028] The water supply block 8 has a three-way pipe 11 inside, which allows the operator to control the connection between the water inlet pipe 2 and the first water outlet pipe 4 or the water inlet pipe 2 and the second water outlet pipe 5 by rotating the connecting block 13.

[0029] The presence of an indicator arrow 14 allows operators to visually observe whether the inlet pipe 2 is connected to the first outlet pipe 4 or whether the inlet pipe 2 is connected to the second outlet pipe 5.

[0030] Working principle: The water supply tube connection device used in this type of endoscope first inserts the water supply hose into the inlet pipe 2, then inserts the hose connected to the output end of the water pump into the first outlet pipe 4, and inserts the hose connected to the output end of the pump that supplies other liquids into the second outlet pipe 5. At this time, the connecting block 13 is rotated according to the needs of the endoscope operation to connect the inlet pipe 2 with the first outlet pipe 4 or the inlet pipe 2 with the second outlet pipe 5. This allows the liquid to be switched in a closed environment without disconnecting the water supply hose, effectively avoiding the risk of infection of the water supply hose connector and part of the inner wall, thereby reducing the risk of infection to the patient during the endoscopy operation.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
