Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] As Figure 1 shown:

[0024] A kind of catheter slip-off prevention alarm, including catheter main body 1.

[0025] In the present embodiment: the existing device {publication (announcement) number}: CN216855360U discloses a chest lavage drainage catheter and a chest catheter assembly, to solve the technical problems existing in the prior art, as disclosed in the background art above, "the above design, although one pipe is used, the catheter does not need to be frequently replaced, and multiple catheters do not need to be used at the same time, saving operation time, facilitating operation, simplifying the entire operation process and improving efficiency, but if the patient moves a lot, the catheter is pulled, twisted and fixed, the catheter still has the risk of falling off, cannot give a warning when the catheter has the risk of slipping, cannot remind medical staff or patients to take measures, and increases patient anxiety", in combination, this problem is obviously a real problem and is relatively difficult to solve, therefore, to solve this technical problem, a pre-falling prompt assembly 2 is added to the present application file, and the electric power equipment involved in the product is powered by an external power source.

[0026] Further,

[0027] As Figures 1-3 shown:

[0028] The pre-falling prompt assembly 2 is installed on the catheter body 1, the pre-falling prompt assembly 2 includes a mounting seat 203 arranged below the catheter body 1 and two tightening belts 201 and 202 respectively hinged on both sides of the mounting seat 203 through a hinge shaft one, one end of the tightening belt 201 is hinged with a U-shaped bracket 216 through a hinge shaft two, a rectangular slot is formed on one side of the tightening belt 201, and a limiting buckle rod 217 is arranged in the rectangular slot, the limiting buckle rod 217 is hinged with the tightening belt 201 through a hinge shaft three, and a plurality of limiting holes 218 arranged at equal intervals are formed on the surface of the tightening belt 202 and inserted with the limiting buckle rod 217;

[0029] A mounting groove is formed on the surface of the mounting seat 203, and a limiting rod 204 arranged in symmetry is arranged in the mounting groove, an activity seat 206 is slidably connected between the two limiting rods 204, the activity seat 206 is provided with a clamping seat 210, and the clamping seat 210 is arranged on the surface of the catheter body 1;

[0030] A pressure sensor 205 corresponding to the activity seat 206 is arranged in the mounting groove, an alarm body 209 is fixedly installed on the upper surface of the mounting seat 203 through bolts, a storage battery is arranged in the mounting groove of the mounting seat 203, the pressure sensor 205 is fixedly installed on the mounting seat 203 through bolts, and the two limiting rods 204 are fixedly connected with the mounting seat 203.

[0031] In the embodiment: the catheter slip-off alarm, in use, first fix the catheter body 1 at the patient's catheter site, then pass the tightening belt 201 and the tightening belt 202 around the patient's chest, and pass the tightening belt 202 through the U-shaped bracket 216, and insert the limiting buckle rod 217 into the limiting hole 218 of the tightening belt 202, which can fix the structure on the patient's skin. When the catheter body 1 is pulled, the clamping seat 210 is moved, the movable seat 206 is driven to slide on the limiting rod 204 by the clamping seat 210, and the movable seat 206 is pressed against the pressure sensor 205. When the pressure sensor 205 is pressed, and when the pulling force on the catheter exceeds the preset safety threshold of the pressure sensor 205, the pressure sensor 205 will immediately control the alarm body 209 to send an alarm signal, reminding the operator to take appropriate measures. Through this operation, when the patient moves a lot and pulls, twists the catheter and is not firmly fixed, there is a risk of catheter falling off, the alarm body 209 can be used for early warning to remind medical staff or patients to take measures, reduce patient anxiety, and improve the use effect of the device.

[0032] It should be noted that when the catheter body 1 is pulled, the clamping seat 210 is pressed against the pressure sensor 205, and the sensitive element (such as piezoelectric material, strain gauge, etc.) inside the pressure sensor 205 senses the pressure change caused by the pressing. The sensed pressure change is converted by the pressure sensor 205 into an electrical signal, usually a voltage or current signal, the size of which is proportional to the pressure received. The converted electrical signal usually needs to be processed by a signal conditioning circuit to improve the quality and accuracy of the signal. The conditioned signal is sent to a microcontroller or processor for analysis. The algorithm inside the system will evaluate whether the signal size exceeds the preset threshold to determine whether the alarm body 209 needs to be started. If the analysis result shows that the pressure value exceeds the standard, the processor will send a control signal to the alarm body 209, which instructs the alarm body 209 to start and issue a predetermined alarm prompt.

[0033] It should be noted that the specific connection method is that the battery supplies power to the entire system, with the positive and negative poles connected to the power supply ends of each device. The output end of the pressure sensor 205 is first connected to the input end of the signal amplifier, and after signal amplification, it is connected to the corresponding input pin of the microcontroller. The microcontroller analyzes and processes the amplified pressure signal, and when it judges that the alarm condition is met, the output pin of the microcontroller is connected to the control end of the alarm body 209, thereby triggering the alarm body 209 to issue an alarm prompt.

[0034] It should be noted that the battery is used to power the pressure sensor 205 and the alarm body 209;

[0035] Need to explain: when the device is fixed on the skin, the catheter body 1 at the patient's diversion site is in a tight state, and the clamping seat 210 on the catheter body 1 is close to the pressure sensor 205.

Through the arrangement of the guide rod 208, the clamping seat 210 can be limited, so that the movement of the clamping seat 210 is more stable. By driving the two groups of clamping seats 210, the flexible clamping of the catheter body 1 is realized. The structure can be separated from the catheter body 1, so that the structure can be recycled, saving the manufacturing cost.

[0039] Since the side of the two groups of clamping seats 210 close to each other is in an arc-shaped structure, the contact area with the catheter body 1 can be increased. At the same time, through the arrangement of the plurality of arc-shaped silica gels 211, the friction between the clamping seat 210 and the catheter body 1 can be increased, further improving the fixing effect.
