Description

Technical Field

[0001] The invention belongs to the field of medical instruments, and specifically provides a gastrointestinal nutrition tube anti-blockage alarm device. Background Art

[0002] Gastrointestinal feeding tubes, also known as enteral feeding tubes, are mainly used to provide nutritional support for patients who are unable to eat normally or whose digestion and absorption functions are impaired.

[0003] For example, some patients with digestive tract tumors have severe stenosis of the lumen and are unable to place stents. Or patients with gastric cancer, although they can eat, have lost their normal digestive function due to the tumor in the stomach, resulting in repeated vomiting and gradual weight loss. In clinical practice, these patients are generally given nutrition through gastrointestinal nutrition tubes.

[0004] However, due to the limitation of being inserted into the human body, the diameter of the gastrointestinal nutrition tube cannot be made too large, which makes it easy for blockage to occur when delivering nutrient solution, causing nutrient delivery obstacles. If not discovered in time, it will endanger the patient's life.

[0005] Therefore, there is an urgent need for a device that can monitor the status of the gastrointestinal feeding tube and alleviate the blockage in a timely manner. Summary of the invention

[0006] In order to solve the above-mentioned problem of gastrointestinal nutrition tube blockage, the present invention provides a gastrointestinal nutrition tube anti-blockage alarm device, which alleviates the blockage in the gastrointestinal nutrition tube by the reciprocating motion of the steel rope, and monitors the blockage status in the gastrointestinal nutrition tube based on the reciprocating motion displacement change of the steel rope.

[0007] Specifically, a gastrointestinal nutrition tube anti-blocking alarm device includes: a steel rope; a stepping motor for dragging the steel rope to reciprocate; and a tail end fixer for helping the steel rope return to its original position;

[0008] The tail end fixer is provided with a clamping tooth on the outside and an elastic drawstring on the inside. One end of the steel rope is fixedly connected to the rotating shaft of the stepping motor and the other end is connected to the elastic drawstring.

[0009] The gastrointestinal nutrition tube anti-blocking alarm device is also provided with a three-way pipe and a control unit for controlling the reciprocating rotation of a stepper motor. The stepper motor is arranged at the head end of the three-way pipe, and a steel rope passes through the three-way pipe. A position sensor close to the steel rope is arranged in the three-way pipe, and a buzzer is arranged on the top of the three-way pipe. The position sensor and the buzzer are electrically connected to the control unit.

[0010] Furthermore, flexible strips are spirally distributed on the periphery of the steel rope.

[0011] Furthermore, a battery is provided in the three-way pipe.

[0012] Furthermore, the elastic rope head end and the steel rope tail end are provided with mutually cooperating clamping structures;

[0013] Furthermore, the tail end of the steel rope is provided with a clamping part, the inside of which is provided with a circular slot, and a rectangular slot arranged perpendicular to the circular slot, and the rectangular slot penetrates the outer end surface of the steel rope. The end of the elastic pull rope is provided with a clamping block, the outer diameter of which is smaller than the inner diameter of the circular slot, the thickness is smaller than the slot depth of the circular slot, and the width is smaller than the width of the rectangular slot.

[0014] Furthermore, the tail end fixer body is a sleeve, the engaging teeth are "L" shaped and fixedly arranged on both sides of the tail end of the sleeve, and the elastic drawstring is fixedly arranged inside the sleeve.

[0015] Furthermore, a "U"-shaped slot is provided on the engaging tooth.

[0016] Furthermore, a pulley is fixedly provided on the rotating shaft of the stepping motor, a steel rope is fixedly connected to the pulley, and a pull ring is fixedly provided on the stepping motor section of the steel rope.

[0017] The beneficial effects of the present invention are:

[0018] 1. In order to timely detect the blockage of the gastrointestinal nutrition tube, the present invention adopts a motor and an elastic stretching and pulling steel rope to monitor whether the tube is unobstructed; specifically, a displacement sensor is arranged on the outside of the steel rope to monitor the displacement change of the steel rope in real time; in the present invention, the steel rope is placed in the tube, and if the blockage in the tube will increase the movement resistance of the steel rope, the displacement will also change relatively at this time, and the displacement sensor monitors the displacement change and converts it into an electrical signal, and finally the electrical signal is converted into an alarm model, such as a buzzer alarm, under the action of the control system; this facilitates medical staff to monitor the internal blockage of the gastrointestinal nutrition tube in real time, and if blockage occurs, it can be dealt with in time to avoid endangering the life and health of the patient.

[0019] 2. In order to alleviate the blockage state when the gastrointestinal nutrition tube is blocked, the present invention is provided with a reciprocating steel rope, and a spirally distributed flexible strip is provided on the outer periphery of the steel rope; when the steel rope reciprocates, the flexible strip will repeatedly clean the inside of the tube like a brush to avoid blockage caused by excessive residual nutrients, thereby reducing the risk of blockage and alleviating the burden of medical staff's supervision and blockage treatment.

[0020] In summary, the present invention adopts a reciprocating steel rope mode in conjunction with a control system, which can not only monitor the blockage situation in the tube, but also actively clean the residue inside the tube to avoid excessive blockage, thereby reducing the burden on medical staff and improving the quality of gastrointestinal nutrition tube feeding.

DETAILED DESCRIPTION

[0032] In order to solve the problem of gastrointestinal nutrition tube blockage and real-time monitoring of the blockage status, the present invention provides a gastrointestinal nutrition tube anti-blockage alarm device, including: a steel rope 2; a stepper motor 113 for dragging the steel rope 2 to move; and a tail end fixer 3 for returning the steel rope 2; under the action of the stepper motor 113 and the tail end fixer 3, the steel rope 2 reciprocates, and the present invention uses the reciprocating motion status to monitor whether the tube is blocked and clean the nutrients remaining on the inner wall of the tube to avoid excessive blockage of the nutrition tube.

[0033] The following is combined with Figure 1-9 Provide detailed application examples.

[0034] Example 1

[0035] In this embodiment, the tail end fixer 3 is preferably provided with a snap-on tooth 32 on the outside, and an elastic pull rope 33 is preferably provided on the inside. One end of the steel rope 2 is fixedly connected to the rotating shaft of the stepping motor 113, and the other end is connected to the elastic pull rope 33. When the stepping motor 113 pulls up the steel rope 2, the steel rope 2 will be pulled back downward under the elastic action of the elastic pull rope 33; when the stepping motor 113 is activated again, the steel rope 2 is pulled up again, thereby preventing the reciprocating motion of the steel rope 2. It should be noted that in this embodiment, the torque generated by the stepping motor 113 is greater than the pull rope torque of the elastic pull rope 33, so as to ensure that the stepping motor 113 overcomes the pulling force of the elastic pull rope 33 to do work and pull the steel rope 2 to move.

[0036] In order to complete the control of the stepper motor 113 and realize the blocking monitoring, in the present embodiment, the main body of the device is also provided with a three-way pipe 12 and a control unit 111 for controlling the reciprocating rotation of the stepper motor 113. The stepper motor 113 is arranged at the head end of the three-way pipe 12, and the steel rope 2 passes through the three-way pipe 12; a position sensor and a battery 112 close to the steel rope 2 are arranged in the three-way pipe 12, and a buzzer 13 is arranged on the top of the three-way pipe 12; the position sensor and the buzzer 13 are electrically connected to the control unit 111.

[0037] Specifically, the control unit 111 controls the stepper motor 113 to rotate intermittently, thereby driving the steel rope 2 to be pulled intermittently. During this process, the position sensor is close to the steel rope 2 to monitor the displacement distance of the steel rope 2 in real time. If the displacement is less than the standard displacement, the control unit 111 controls the buzzer 13 to alarm, and it is determined that the pipe is blocked, thereby realizing blockage monitoring.

[0038] In this embodiment, it should be noted that the standard displacement is the distance that the stepper motor 113 pulls when the steel rope 2 is not subject to external friction resistance.

[0039] Example 2

[0040] Based on the above-mentioned embodiment 1, in this embodiment, flexible strips 21 are spirally distributed on the outer circumference of the steel rope 2; when the steel rope 2 reciprocates, the flexible strips 21 also reciprocate with the steel rope 2 to clean the residual substances attached to the inside of the pipe to avoid excessive accumulation thereof causing blockage inside the pipe.

[0041] Example 3

[0042] Based on the above-mentioned embodiment 1, this embodiment provides a preferred embodiment form of the clamping connection between the elastic rope and the steel rope 2.

[0043] In this embodiment, the tail end fixer 3 is fixed to the tail end of the gastrointestinal nutrition tube, but for the sake of stability, refer to the attached Figure 6The outer diameter of the tail end fixer 3 is larger than the inner diameter of the gastrointestinal nutrition tube, so the tail end fixer 3 cannot pass directly through the tube and can only be assembled in a detachable manner, that is, a mutually cooperating clamping structure is set at the head end of the elastic rope and the tail end of the steel rope 2.

[0044] Specifically, in this embodiment, a clamping portion 22 is provided at the tail end of the steel rope 2 , a circular hollow groove is provided inside the clamping portion 22 , and a rectangular groove is provided perpendicular to the circular hollow groove, and the rectangular groove penetrates to the outer end surface of the steel rope 2 .

[0045] In this embodiment, the end of the elastic pull rope 33 is provided with a clamping block 34, the outer diameter of which is smaller than the inner diameter of the circular slot, the thickness is smaller than the slot depth of the circular slot, and the width is smaller than the width of the rectangular slot. In actual use of this embodiment, the clamping block 34 is inserted from the rectangular slot into the circular slot, and then rotated 90 degrees to complete the docking; when disassembly is required, the clamping block 34 is rotated 90 degrees in the opposite direction to be taken out through the rectangular slot.

[0046] Example 4

[0047] Based on the above-mentioned embodiment 3, this embodiment provides a preferred fixing form of the tail end fixer 3 and the gastrointestinal nutrition tube.

[0048] See attached Figure 6 In this embodiment, the main body of the tail end fixer 3 is a sleeve 31, the engaging teeth 32 are “L” shaped and fixedly arranged on both sides of the tail end of the sleeve 31, and the elastic pull rope 33 is fixedly arranged inside the sleeve 31.

[0049] Specifically, a "U"-shaped slot is provided on the engaging teeth 32, and the tail end fixer 3 is engaged with the side wall of the gastrointestinal nutrition tube through the slot.

[0050] Example 5

[0051] In this embodiment, a pulley 114 is fixedly provided on the rotating shaft of the stepper motor 113, and the steel rope 2 is fixedly connected to the pulley 114, which can amplify the pulling torque of the stepper motor 113 and facilitate the stable fixing of the steel rope 2, thereby improving the stability of the operation of the steel rope 2.

[0052] Example 6

[0053] In this embodiment, a pull ring 23 is fixedly provided at one end of the stepper motor 113 of the steel rope 2. When the blockage is serious and the stepper motor 113 can no longer pull the steel rope 2, the pull ring 23 can be used to manually pull the steel rope 2 to alleviate or clear the blockage in the pipe.

[0054] In summary, the reciprocating motion of the steel rope 2 provided by the present invention and the structure cooperating with the movement of the gastrointestinal nutrition tube can not only monitor the blockage in the tube, but also clear the blockage in the tube, thereby reducing the burden on doctors and patients and improving the quality of gastrointestinal nutrition tube feeding.
