Description

Technical Field

[0001] The utility model relates to the technical field of nursing care in intensive care units, in particular to an anti-extubation alarm device. Background Art

[0002] The more common operations in the ICU nursing include general nursing operations, such as providing patients with oxygen, suctioning sputum, infusion, blood drawing, and urination and defecation management, etc. The patients also need to be tube-fed with nutrient solution and gastrointestinal decompression, and the patient's 24-hour fluid intake and output must be managed and recorded, and various drainage tubes in the patient's body must be maintained. In the process of tube feeding nutrient solution, gastrointestinal decompression, and maintenance of various drainage tubes, the catheter needs to be fixed in the patient's body for a long time. Forest farms generally use some straps or medical tapes to fix it, and some will also use some alarm devices to monitor the catheter in the patient's body to avoid the catheter falling off after the patient turns over or moves accidentally, and cannot be discovered in time.

[0003] The patent specification with announcement number CN218729323U discloses an anti-extubation alarm, which uses the cooperation of magnetic sensors and magnetic contacts to enable the control module to control the cellular speaker to alarm and prompt the patient's family or medical staff, so that there is no need to restrain the patient with a restraint belt, effectively preventing the patient from accidentally extubating, and solving the discomfort and resistance caused to the patient, thereby meeting the needs of the anti-extubation alarm. The positioning and fixation of the catheter are achieved through the cooperation of a sliding rod, a limit plate and a torsion spring, so that the position of the limit plate changes when the rotating rod rotates, solving the problem that the anti-extubation alarm cannot be adjusted after being fixed, so that the direction can be adjusted in real time according to the patient's movement, thereby increasing the monitoring range of the anti-extubation alarm and greatly increasing the practicality of the alarm.

[0004] However, in the implementation of relevant technologies, it was found that the anti-extubation alarm of the above design has the following problems: it achieves the clamping and fixing effect of the catheter through the limit plate, but in the clamping process, no anti-slip measures are set on the inner side of the limit plate, so when the catheter slides along the structure of the limit plate, the slide bar and the torsion spring will not change, so the magnetic sensor and the magnetic contact point cannot make a corresponding alarm, and even if an alarm is generated subsequently, it may be because the catheter is located in the clamping part of the limit bar and rotates or twists accidentally when the patient turns over or moves, which leads to the inaccurate monitoring structure. In view of this, an anti-extubation alarm device is provided to overcome the above defects. Utility Model Content

The first clamping assembly and the second clamping assembly can achieve a fixing effect on the catheter and the catheter head, and the guide rod and the compression spring are used to adjust the diameter of the catheter clamped by the clamping plate, which also facilitates the clamping of catheters of different diameters, thereby increasing the practicality of the device.

[0011] As a further description of the above technical solution: one end of the compression spring is fixedly mounted on the clamping plate, and the other end is fixedly mounted on the sleeve and the mounting port. The compression spring can continuously press against the clamping plate so that the clamping plate can always maintain a fitting effect with the catheter and the catheter head.

[0028] The monitoring component 4 includes a fixing plate 401, which is fixedly mounted on the outside of the ring 1. The inner surface of the fixing plate 401 is provided with multiple groups of mounting grooves 402. The mounting plate 403 is elastically mounted inside the mounting groove 402. A piezoelectric sensor 404 is fixedly mounted above the mounting plate 403.

[0029] As a further implementation scheme of the above technical scheme: the monitoring component 4 is electrically connected to the alarm speaker 9 through the cable 5. The electrical connection between the monitoring component 4 and the alarm speaker 9 can realize the effect of alarming the patient or medical staff through the alarm speaker 9 after the pressure change occurs in the piezoelectric sensor 404 of the monitoring component 4.

[0030] Embodiment 2

[0031] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0032] The first clamping assembly 3 and the second clamping assembly 8 both include a clamping plate 10, a guide rod 11 is fixedly installed on the outer side of the clamping plate 10, and the inner side of the clamping plate 10 is made of rubber material, and a compression spring 12 is sleeved on the outer side of the guide rod 11. The first clamping assembly 3 and the second clamping assembly 8 can achieve a sleeve fixing effect on the catheter and the catheter head, and the guide rod 11 and the compression spring 12 are used to adjust the diameter of the catheter clamped by the clamping plate 10, which is also convenient for clamping catheters of different diameters, thereby increasing the practicality of the device.

[0033] As a further implementation scheme of the above technical scheme: one end of the compression spring 12 is fixedly mounted on the clamping plate 10, and the other end is fixedly mounted on the sleeve 2 and the mounting port 7. The compression spring 12 can continuously press against the clamping plate 10, so that the clamping plate 10 can always maintain a fitting effect with the catheter and the catheter head.

[0034] As a further implementation scheme of the above technical scheme: sliding grooves 13 matching the guide rod 11 are provided at the connection between the sleeve 2 and the installation opening 7 and the guide rod 11. The sliding grooves 13 are provided on the sleeve 2 and the installation opening 7 to facilitate the sliding of the guide rod 11.

[0035] Embodiment 3

[0036] In addition to all the technical features of the first embodiment, this embodiment also includes:

[0037] As a further implementation scheme of the above technical scheme: the collar 1 and the box 6 are both made of plastic material. The plastic material makes the overall structure light and reduces the downward pressure and falling of the catheter during use.

[0038] As a further implementation scheme of the above technical scheme: a battery cavity 14 is opened on the surface of the kit 6, and a replaceable battery pack 15 is arranged inside the battery cavity 14, and the replaceable battery pack 15 is electrically connected to the cable 5 and the alarm horn 9.

[0039] In the specific implementation, the ring 1 and the sleeve box 6 are respectively sleeved on the catheter and the catheter head. During the sleeve process, the catheter head will first pass through the sleeve box 6 and then pass through the ring 1. During the sleeve process, the catheter and the catheter head will squeeze the clamping plate 10, and the clamping plate 10 will squeeze the guide rod 11 and the compression spring 12, so that the diameter of the catheter clamped by the clamping plate 10 has a certain adjustment space, and it is also convenient to clamp catheters of different diameters. Then the ring 1 and the catheter head can be fixed on the skin surface required by the patient. When the ring 1 is fixed, the monitoring component 4 outside the ring 1 will contact the patient's skin, and then the catheter can be adjusted. During the anti-extubation monitoring, the piezoelectric sensor 404 of the monitoring component 4 will continue to contact the patient's skin. When the catheter head and the ring 1 are separated from the patient's skin, the multiple groups of piezoelectric sensors 404 will use the cable 5 to transmit information to the alarm speaker 9. Then the patient or medical staff will check the catheter. During the monitoring process of the monitoring component 4, when the patient's skin at that place changes, such as wrinkles or turning over, not all of the piezoelectric sensors 404 will be separated from the patient's skin. In this case, the piezoelectric sensors 404 will not directly transmit information to the alarm speaker 9.
