[0030] Please see Figure 1-4 As shown, this utility model mainly provides a single-J tube constant pressure flushing device to facilitate patients' family members to flush the tubes at home, reduce patients' discomfort, and achieve the purpose of preventing tube blockage and infection. Based on this, the device includes a sleeve 1, a push rod 2, a crossbar 3, and a rotating clamp 4; wherein, the sleeve 1 is fixedly connected to the crossbar 3, the push rod 2 is disposed inside the sleeve 1, and the crossbar 3 is located at the top of the sleeve 1, and its overall appearance is similar to an injection syringe; wherein, the bottom end of the sleeve 1 is tapered, which facilitates the aspiration of the flushing fluid; in this embodiment, a receiving chamber 5 is provided inside the crossbar 3, and the rotating clamp 4 is disposed inside the receiving chamber 5; the rotating clamp 4 is rotatably connected to the crossbar 3; the rotating clamp 4 includes a disc 41 located inside the receiving chamber, a vertical rod 42 located on the disc, and a rotating head 43 disposed at the top of the vertical rod, wherein the disc 41, the vertical rod 42, and the rotating head 43 are integrally connected and are in the shape of an I-beam; a rotating shaft 6 is provided at the connection between the rotating clamp 4 and the crossbar 3, and the rotating shaft 6 is located at the connection between the vertical rod and the crossbar (e.g., Figure 3 As shown in the figure, the rotating head 4 can rotate 360° in the receiving cavity of the crossbar 3 by rotating the rotating shaft. In this embodiment, the rotating shaft 6 is a known technology, and its structural principle will not be described in detail here.
[0031] Refer again Figure 3 As shown, a locking cavity 44 is provided inside the disc 41, and an opening 45 is provided on the locking cavity 44. The push rod 2 enters the locking cavity 44 through the opening 45 and is fixed in the locking cavity 44 under the rotation of the rotating clamping head 4. Specifically, the push rod 2 enters the corresponding opening in a horizontal state, and then the rotating clamping head is rotated clockwise or counterclockwise at 0-90° to make the push rod 2 and the opening 45 form a staggered intersection, thereby fixing the push rod 2 in the locking cavity 44.
[0032] like Figure 4As shown, in this embodiment, the push rod 2 includes a push rod head 21, a push rod body 22, a push-pull rod 23, a constant force spring 24, and a piston 25. The push rod head 21 and the push-pull rod 23 are both mounted on the push rod body, and the constant force spring 24 is fixedly mounted between the push-pull rod 23 and the piston 25. Correspondingly, slots 11 are provided on both sides of the sleeve 1. The push-pull rod is located within the slots 11, and can move within the slots 11 under the traction of external forces, thus moving the push rod 2. After the fixation is released, the push rod 2 will slowly move downwards under negative pressure (two or more pistons can be provided to increase the effect of negative pressure), causing the push-pull rod to move again within the slots until it stops moving at the lowest position of the slot.
[0033] In this embodiment, the size of the push rod head 21 is smaller than the size of the opening on the engaging cavity 44, so that it can enter the engaging cavity 44; and the size of the opening is smaller than the size of the engaging cavity, so that the push rod 2 after entering can be rotated and fixed in the engaging cavity in conjunction with the rotating clamp head.
[0034] In this embodiment, multiple constant force springs 24 are provided and symmetrically arranged on both sides of the push rod body 22. The number of springs can be increased or decreased according to the condition of different patients, so as to meet the optimal speed for single-J tube flushing for different patients.
[0035] In this embodiment, the piston 25 is in contact with the inner wall of the sleeve 1. This arrangement facilitates the formation of negative pressure, thereby making it easier to move the push rod after it has been released from its fixed position.
[0036] In this embodiment, the push-pull rod 23 is also provided with anti-slip texture, which can increase the friction between the fingers and the push-pull rod, increase the stability when pushing and pulling, and reduce unnecessary slippage.
[0037] In this embodiment, the rotating head 43 on the rotating chuck 4 is also provided with a rotation angle, so that the actual rotation angle can be known when it rotates (not clearly marked in the figure for simplicity), thereby facilitating the fixing and release of its push rod and improving the ease of use.
[0038] The method of using this utility model is as follows: When using it, the patient can hold the sleeve with one hand and use the other hand to pull the push-pull rod on the sleeve upwards until it reaches the maximum position of the groove – the top position (at this time, the push rod head has entered the locking cavity inside the disc through the opening, and the height of the push rod head should be higher than the bottom surface of the locking cavity, thus facilitating the rotation of the locking head). Then, rotate the locking head counterclockwise or clockwise 0-90° to stagger the position of the push rod head and the opening, so that both ends of the push rod head can engage in the locking cavity inside the disc (e.g., ...). Figure 3(As shown); When rinsing, simply rotate the rotating clamp to a certain angle again so that the push rod head coincides with the opening. At this time, the liquid in the sleeve will maintain a certain force and slowly move downward under the action of the constant force spring and piston, thereby driving the liquid in the sleeve to perform rinsing work, thereby reducing the discomfort caused to the patient by uneven rinsing force by family members, and improving the comfort and safety of the patient during use.
[0039] It should be noted that this utility model has a simple structure and is easy to operate. The locking mechanism between the rotating clamp and the push rod keeps the push rod fixed after the liquid is drawn in. By rotating the push rod, the liquid inside moves downward with a certain force, allowing the liquid in the sleeve to stably enter the single-J tube, completing the flushing work of the single-J tube. This reduces unnecessary pain and also alleviates the psychological burden on family members when pushing the push rod. At the same time, the entire device can be made of PVC material (except for the piston), which is low in cost and can be mass-produced. During use, it can be used for single purposes, avoiding exogenous infection caused by repeated use of the same needle, which would increase medical expenses and improve the convenience of use.
