[0041] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] In the description of the embodiments of the present utility model, it should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the embodiments of the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0043] Combine the following Figure 1 to Figure 2 The output pipe internal pressure monitoring device provided by the embodiment of the utility model is described.

[0044] like Figure 1 and Figure 2 As shown, an output pipe internal pressure monitoring device provided by an embodiment of the utility model includes a pipe body 1, a piston 2, a pipe head 3, an inner shell 4 and an outer shell 5.

[0045] Among them, the inside of the tube body 1 is slidably connected with a piston 2, and one end of the tube body 1 is connected with a tube head 3, which is used to connect the output tube; and the diameter of the tube head 3 is smaller than the tube body 1; the sterile water is transported to the output tube through the tube body 1 and the tube head 3, and then transported to the human body through the output tube. The inner shell 4 at least covers the bottom side and the head side of the tube body 1, and under the movement of the piston 2, the tube body 1 and the inner shell 4 move relative to each other along the first direction; wherein the first direction is the axial direction of the tube body 1. When the piston 2 moves, the tube body 1 will drive the inner shell 4 to move together under the action of friction. The outer shell 5 is stationary, and as the tube body 1 moves, the outer shell 5 and the inner shell 4 have a contact surface and fit together; the contact surface is perpendicular to the first direction; the pressure sensor 6 is located between the inner shell 4 and the outer shell 5 to detect the force on the contact surface.

[0046] In the output pipe monitoring device provided by the embodiment of the utility model, the piston 2 moves, and through the thrust transmission, the pipe body 1 first fits with the inner shell 4, and the inner shell 4 then contacts the pressure sensor 6 to generate pressure. When the output pipe is unobstructed, the pressure transmitted to the pressure sensor 6 is consistent; when the output pipe is blocked, a greater force is required to push the piston 2, thereby increasing the sensor pressure, that is, whether the output pipe is unobstructed is determined by the pressure sensor 6. The pressure sensor 6 is located on the outside of the output pipe, and no waterproof treatment is required, which simplifies the process and reduces the cost.

[0047] It should be understood that the utility model determines whether the channel in the output pipe is unobstructed by conducting external thrust and sensing the pressure sensor 6 to determine the pressure change in the output pipe.

[0048] In one embodiment of the utility model, a thrust mechanism 7 is further included, which is connected to the piston 2 and is used to provide power for the movement of the piston 2. The thrust mechanism 7 can be designed and adjusted according to different application requirements to meet different pressure and flow requirements.

[0049] In one embodiment of the present invention, the thrust mechanism 7 is fixedly connected to the housing 5. It can be understood that the mounting base of the thrust mechanism 7 is fixedly connected to the housing 5 so that the housing 5 is fixed and remains stationary, making the thrust mechanism 7 more stable and being able to more accurately control the position of the piston 2, thereby achieving accurate regulation of the pressure in the output pipe. The thrust mechanism 7 can generate thrust as needed to control the position of the piston 2 in the pipe body 1.

[0050] In one embodiment of the present invention, the inner shell 4 includes a first horizontal portion 41 and a first vertical portion 42, wherein the first horizontal portion 41 is arranged at the bottom side of the tube body 1 along the first direction, and the first horizontal portion 41 is slidably connected to the tube body 1; the first vertical portion 42 is arranged perpendicular to the first horizontal portion 41, and the first vertical portion 42 is located at the head side of the tube body 1. The shape of the first horizontal portion 41 is generally semi-cylindrical, which matches the shape of the tube body 1.

[0051] The shell 5 includes a second horizontal portion 51 and a second vertical portion 52, and the second horizontal portion 51 is arranged on the bottom side of the first horizontal portion 41 along the first direction; the second horizontal portion 51 and the first horizontal portion 41 are slidably connected; the second vertical portion 52 is vertically arranged to the second horizontal portion 51, and a contact surface is formed between the second vertical portion 52 and the first vertical portion 42; the pressure sensor 6 is located at the contact surface, and the pressure sensor 6 can be fixed on the second vertical portion 52.

[0052] The pressure sensor 6 may be a thin film pressure sensor.

[0053] When the thrust mechanism 7 pushes the piston 2 to move, the tube body 1 first fits with the inner shell 4 through thrust transmission, and the inner shell 4 and the pressure sensor 6 fixed on the outer shell 5 generate pressure. When the output pipe is unobstructed, the pressure transmitted to the pressure sensor 6 is consistent; when the output pipe is blocked, the thrust mechanism 7 pushes to increase the pressure of the pressure sensor 6, and the pressure sensor 6 can be used to sense the pressure to determine whether the pipe is unobstructed.

[0054] In one embodiment of the present invention, the pressure sensor 6 comprises a thin film pressure sensor. By using the thin film pressure sensor, it is more convenient to install and use.

[0055] In an embodiment of the present invention, a first through hole is defined in the second horizontal portion 51 , and the pressure sensor 6 passes through the first through hole and extends to the outside of the second horizontal portion 51 .

[0056] like Figure 2 As shown, in one embodiment of the utility model, the inner shell 4 includes a first horizontal portion 41, a first vertical portion 42 and a limiting portion 43, the first horizontal portion 41 is arranged on the bottom side of the tube body 1 along the first direction, and the first horizontal portion 41 is slidably connected to the tube body 1; the first vertical portion 42 is perpendicularly arranged to the first horizontal portion 41, and the first vertical portion 42 is located on the head side of the tube body 1; the limiting portion 43 is perpendicularly and integrally arranged to the first horizontal portion 41, and extends to the side away from the tube body 1.

[0057] The shell 5 includes a second horizontal portion 51 and a second vertical portion 52. The second horizontal portion 51 is arranged on the bottom side of the first horizontal portion 41 along the first direction. A second through hole is opened on the second horizontal portion 51, and the limiting portion 43 passes through the second through hole. The second vertical portion 52 is vertically arranged to the second horizontal portion 51. The pressure sensor 6 is arranged on the second horizontal portion 51, and the pressure sensor 6 abuts against the limiting portion 43 to form a contact surface.

[0058] When the piston 2 moves, the thrust is transmitted, and the first horizontal portion 41 slides with the tube body 1 until the first vertical portion 42 fits with the tube body 1. The first vertical portion 42 contacts the pressure sensor 6 to generate pressure. When the output pipe is unobstructed, the pressure transmitted to the pressure sensor 6 is consistent. When the output pipe is blocked, the thrust mechanism 7 pushes to increase the pressure of the pressure sensor 6. The pressure sensor 6 can sense the pressure to determine whether the pipe is unobstructed.

[0059] In the above embodiments, the pressure sensor 6 includes a micro pressure sensor. The pressure sensor may also be in other structural forms as long as it can achieve pressure monitoring.

[0060] Therefore, the utility model realizes monitoring the internal pressure of the output pipe through a simple detection device.
