Description

Technical Field

[0001] The invention relates to the technical field of alarm devices, in particular to an anti-blocking alarm device for a gastrointestinal nutrient tube. Background Art

[0002] A gastrointestinal feeding tube is a tube that helps deliver necessary water and food to patients who cannot swallow under special circumstances, so as to provide the patient with necessary nutrition and ensure the energy required for the patient to maintain vital signs. However, there are certain problems in the actual use of gastrointestinal feeding tubes. In order to ensure that the gastrointestinal feeding tubes can be smoothly plugged in, the diameter of the gastrointestinal feeding tubes is relatively thin. Therefore, when delivering food, the gastrointestinal feeding tubes are often blocked. Since there are many patients in the hospital, it is impossible for medical staff to pay attention to every patient at all times. Therefore, when the gastrointestinal feeding tube is blocked, it cannot be discovered in time, and the blockage cannot be dealt with in time, resulting in certain adverse consequences.

[0034] A matching gear 7 is installed on the alarm bearing sleeve 2, and the matching gear 7 is meshed with the matching rack 37, and a first mounting column 71 is fixedly provided on the lower end of the matching gear 7, and a bearing matching block 72 is fixedly provided on the first mounting column 71, and a matching through hole 73 is opened on the bearing matching block 72, and a rotation locking rod 74 is inserted in the matching through hole 73, and a support plate 75 is fixedly provided on the rotation locking rod 74, and a second spring 76 is sleeved on the rotation locking rod 74, and the two ends of the second spring 76 are respectively fixed on the bearing matching block 72 and the support plate 75, and the rotation locking rod 74 is inserted in the rotation locking hole 271 to realize the relative fixation between the contact matching plate 33 and the alarm bearing sleeve 2.

[0035] The lower end of the first mounting column 71 is sleeved with a first bearing 77, which is installed in the first mounting hole 281, and the lower end of the first mounting column 71 is fixedly provided with a connecting rod 78, on which a limiting insert strip 79 is symmetrically fixed, and the connecting rod 78 is connected to the second mounting column 8.

[0036] The second mounting column 8 is provided with a connecting socket 81, in which a connecting rod 78 is inserted, and limit sockets 82 are symmetrically provided on both sides of the connecting socket 81, in which a limit strip 79 is inserted, and a second bearing 83 is sleeved at the lower end of the second mounting column 8, and the second bearing 83 is installed in the second mounting hole 391, and the diameter of the connecting socket 81 is equal to the diameter of the connecting rod 78, and the limit strip 79 contacts the inner wall of the limit socket 82.

[0037] A load-bearing matching rod 84 is fixedly provided at the lower end of the second mounting column 8 , and a rotating protective plate 85 is fixedly provided on the load-bearing matching rod 84 .

[0038] A movable bearing plate 9 is also installed on the alarm bearing sleeve 2, and a matching plug rod 91 is fixedly provided at one end of the movable bearing plate 9, and the matching plug rod 91 is inserted in the rotation locking hole 271, and a matching sleeve hole 92 is opened on the end of the movable bearing plate 9 away from the matching plug rod 91, and a supporting column 292 is inserted in the matching sleeve hole 92, and the diameter of the matching sleeve hole 92 is equal to the diameter of the supporting column 292.

[0039] An iron ring 93 is embedded and installed on the movable bearing plate 9 outside the matching sleeve hole 92, and a protruding strip 94 is fixedly provided on the end of the movable bearing plate 9 close to the matching sleeve hole 92, and a locking pin 95 is fixedly provided on the protruding strip 94. The locking pin 95 is inserted into the locking matching hole 15 when it plays a fixing role for the alarm bearing sleeve 2. The magnet ring 291 has an adsorption effect on the iron ring 93, which can play a certain fixing role on the movable bearing plate 9, and the second spring 76 can overcome the magnetic force of the magnet ring 291 to push the movable bearing plate 9.

[0040] When the alarm bearing sleeve 2 is in use, the contact matching plate 33 is brought into contact with the injection connector 11 so that the guide matching rod 24 is inserted into the guide matching hole 13, and then the alarm bearing sleeve 2 is pushed toward the injection connector 11 to reduce the distance between the alarm bearing sleeve 2 and the contact matching plate 33, thereby reducing the distance between the alarm bearing sleeve 2 and the gastrointestinal nutrition tube body 1. In this way, the supporting movable plate 3 will be pushed downward under the action of the matching hinge rod 32 to protrude from the outside of the alarm bearing sleeve 2. Before the alarm bearing sleeve 2 is not used, the supporting movable plate 3 is inside the alarm bearing sleeve 2, so that the controller 4, the infrared detector 5 and the alarm 6 are all inside the alarm bearing sleeve 2, which can provide good protection for the three. , to avoid damage during transportation and storage. When the infrared detector 5 is moved out of the alarm carrying sleeve 2, it is facing the gastrointestinal nutrition tube body 1, and can monitor the gastrointestinal nutrition tube body 1 at all times. When it detects that the fluid inside the gastrointestinal nutrition tube body 1 is no longer flowing, the gastrointestinal nutrition tube body 1 is in a blocked state. In this way, the infrared detector 5 transmits the detection result to the controller 4, and the controller 4 controls the alarm 6 to sound an alarm. During the movement, the alarm carrying sleeve 2 will drive the matching gear 7 to rotate under the action of the matching rack 37. As the matching gear 7 rotates, the second mounting column 8 will also be driven to rotate. Since the second mounting column 8 is connected to the matching gear 7 by the connecting rod 78 and the limiting strip 79, The second mounting post 8 can rotate while moving downward with the supporting movable plate 3, thereby making the rotating guard plate 85 rotate 90 degrees so that the gastrointestinal nutrition tube body 1 is between the rotating guard plate 85 and the matching guard plate 38, so that the controller 4, the infrared detector 5 and the alarm 6 can be protected to a certain extent under the action of the rotating guard plate 85 and the matching guard plate 38, and at the same time, the external environment can be prevented from affecting the detection of the infrared detector 5 under the joint action of the rotating guard plate 85 and the matching guard plate 38, thereby ensuring the accuracy of its detection. In addition, the matching gear 7 will also drive the rotating locking rod 74 to rotate during the rotation process, and the rotating locking rod 74 will conflict with the first supporting carrier plate 27 during the rotation process, so that the first supporting The locking lever 77 is in the state of being pressed against the locking cam 74, and the locking cam 75 is in the state of being pressed against the locking cam 74. When the locking lever 77 is in the state of being pressed against the locking cam 74, the locking cam 75 is in the state of being pressed against the locking cam 74.It is very convenient to use. After use, push the movable bearing plate 9 so that the locking pin 95 exits the locking matching hole 15 to put the alarm bearing sleeve 2 in an unlocked state. It can be removed from the injection connector 11 for recycling. At the same time, under the action of the matching plug 91, the rotating locking rod 74 is pushed out of the rotating locking hole 271 to reset it. In addition, when the controller 4, infrared detector 5, and alarm 6 are damaged or fail, the contact matching plate 33 can also be pushed to make the rotating locking rod 74 plugged into the rotating locking hole 271. In this way, the controller 4, infrared detector 5, and alarm 6 can be placed outside the alarm bearing sleeve 2, which is convenient for replacement or maintenance.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
