Description

Technical Field

[0001] This utility model relates to an anti-pull-out device for medical device wiring harnesses. Background Technology

[0002] Hospitals have a large number of medical devices, and there are many wiring harnesses connecting these devices to patients and to each other, especially in hospital wards where medical equipment monitors patients at their bedsides. Because medical staff, family members, and patients are constantly moving around in the wards, and medical equipment may be moved, if the wiring harnesses are not noticed, it is easy to trip over or pull on them, causing the medical equipment to fall or the harness to be pulled off the patient. Either way, this could lead to a serious accident. Currently, the main solution to this problem is to organize the wiring harnesses to prevent them from being pulled, but this is not foolproof, so certain safety hazards still exist during the daily use of medical equipment.

Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Example

[0021] Reference Figures 1-3 This embodiment provides an anti-pull-out device for medical device wiring harnesses, including a connecting wiring harness 1, an elastic element 2, a fixing element 3, and a warning element 4. The connecting wiring harness 1 is uniformly bent into several contraction sections 11 in an "S" shape. The elastic element 2 is disposed on the contraction section 11, and the fixing element 3 is disposed at both ends of the contraction section 11. The fixing element 3 is connected to both ends of the elastic element 2 and is used to buffer against violent stretching of the medical device wiring harness. The warning element 4 is disposed on the fixing element 3 and is used to warn of violent stretching of the medical device wiring harness.

[0022] The connecting harness 1 is mainly used for the connection between the medical device 5 and the patient, as well as the connection between the medical devices 5. In this embodiment, the connecting harness 1 is evenly bent into several contraction segments 11 in an "S" shape. An elastic element 2 is installed on the top of the contraction segment 11, and a fixing element 3 is installed at both ends of the contraction segment 11. The fixing element 3 is connected to the front and rear ends of the elastic element 2, so that the fixing element 3 and the elastic element 2 cooperate with each other to play a certain buffering role for the connecting harness 1, so as to buffer the violent stretching of the wiring harness of the medical device 5. In this embodiment, a warning element 4 is also installed on the fixing element 3. When the wiring harness of the medical device 5 is violently stretched to a threshold, the warning element 4 will sound an alarm to play a warning role. In this embodiment, the connecting harness 1, the elastic element 2, the fixing element 3 and the warning element 4 cooperate with each other to buffer the connection harness 1 when violently stretched, and to provide a warning when the violent stretching reaches the threshold, thereby avoiding the safety hazards caused by the violent stretching of the wiring harness of the medical device 5.

[0023] Specifically, the fastener 3 includes two fixing shells 31 and several clamping strips 32. The fixing shell 31 is composed of two first half-cylinder shells 311 and second half-cylinder shells 312 that are interlocked with each other. The two fixing shells 31 are respectively fitted onto the two ends of the contraction section 11. The several clamping strips 32 are evenly distributed in a petal shape on the inner outer walls of the first half-cylinder shell 311 and the second half-cylinder shell 312.

[0024] In this embodiment, the fixing member 3 mainly consists of two fixing shells 31 and several clamping strips 32. The fixing shell 31 mainly consists of two interlocking first semi-cylindrical shells 311 and second semi-cylindrical shells 312. During installation, the first semi-cylindrical shells 311 and second semi-cylindrical shells 312 are simply fitted onto the connecting wire harness 1 and interlocked to achieve the installation of the fixing shell 31, so as to realize the quick installation and removal of the fixing shell 31. In this embodiment, a fixing shell 31 is respectively fitted at the front and rear ends of the contraction section 11 on the connecting wire harness 1, and the fixing shell 31 is located inside the first semi-cylindrical shell 311 and second semi-cylindrical shell 312. Multiple clips 32 are evenly distributed in a petal shape on the outer wall (inner outer wall of the fixed shell 31). The clips 32 have a certain elasticity. After the fixed shell 31 is installed, the end of the clip 32 away from the fixed shell 31 contacts the connecting wire harness 1, so that the clip 32 wraps around the connecting wire harness 1 in a petal structure. This gives the clip 32 a unidirectional movement effect, that is, the fixed shell 31 can only slide away from the elastic member 2 under the action of the clip 32. This prevents the fixed shell 31 from sliding towards the connecting wire harness 1 when the elastic member 2 is pulled, thereby achieving a better buffering effect.

[0025] Specifically, the warning component 4 includes a sliding hole 41, a sliding pin 42, a trigger part 43, a limit cap 44, a spring 45, a trigger switch 46, a buzzer 47, and a power supply 48. The sliding hole 41 is opened at the top of the first semi-cylindrical shell 311. The sliding pin 42 passes through the sliding hole 41. One end of the sliding pin 42 is fixedly mounted on the elastic member 2. The trigger part 43 is located at the other end of the sliding pin 42. The limit cap 44 is located at the end of the trigger part 43 away from the sliding pin 42. The spring 45 is sleeved between the limit cap 44 and the outer wall of the sliding hole 41. The trigger switch 46 is located on the inner wall of the sliding hole 41. The buzzer 47 and the power supply 48 are both located on the top outer surface of the first semi-cylindrical shell 311. The trigger switch 46, the buzzer 47, and the power supply 48 are electrically connected through a circuit.

[0026] The warning device 4 in this embodiment mainly consists of a sliding hole 41, a sliding pin 42, a trigger part 43, a limit cap 44, a spring 45, a trigger switch 46, a buzzer 47, and a power supply 48. A sliding hole 41 is provided at the top of the first semi-cylindrical shell 311. A sliding pin 42 is fixedly installed at the end of the elastic element 2, penetrating the entire sliding hole 41, allowing the sliding pin 42 to move freely within the sliding hole 41. A trigger part 43 is fixedly installed at the end of the sliding pin 42 away from the elastic element 2, and a limit cap 44 is fixedly installed at the end of the trigger part 43 away from the sliding pin 42, providing a certain limiting effect. A spring 45 is fitted between the limit cap 44 and the outer wall of the sliding hole 41. The force exerted on the spring 45 by the connecting wire harness 1 is greatly reduced. A safety threshold is set, and a trigger switch 46 is installed on the inner wall of the sliding hole 41. A buzzer 47 and a power supply 48 are fixedly installed on the top outer surface of the first semi-cylindrical shell 311. The trigger switch 46, buzzer 47 and power supply 48 are electrically connected through a circuit. When the connecting wire harness 1 is pulled violently, the fixed shell 31 slides away from the elastic member 2. The elastic member 2 pulls the trigger part 43 towards the sliding hole 41 through the sliding pin 42. The limit cap 44 compresses the spring 45 until the set safety threshold is reached. Then, the trigger part 43 on the sliding pin 42 contacts the trigger switch 46 in the sliding hole 41 and compresses the trigger switch 46. The trigger switch 46 activates the buzzer 47 to sound an alarm, thereby achieving the function of early warning.

[0027] Furthermore, the elastic element 2 has an overall spiral structure.

[0028] In this embodiment, the elastic element 2 has an overall spiral structure, so that the elastic element 2 has a larger elongation margin. It should be noted that the elastic element 2 in this embodiment has a certain elasticity and can be made of any elastic material. In this embodiment, the elastic element 2 is made of rubber.

[0029] Furthermore, the elastic element 2 has evenly distributed hanging points 21, and the connecting wire harness 1 is fixedly connected to the elastic element 2 through the hanging points 21.

[0030] In this embodiment, hanging points 21 are evenly installed at the bottom of the elastic member 2. The contraction section 11 of the “S”-shaped connecting wire harness 1 can be directly tied to the hanging points 21 by rope, so as to store the connecting wire harness 1 more neatly.

[0031] Furthermore, the trigger part 43 has a conical structure, and the end of the sliding hole 41 near the spring 45 has a conical hole structure. The sliding hole 41 cooperates with the trigger part 43, and the trigger switch 46 is disposed on the inner wall of the conical hole of the sliding hole 41.

[0032] In this embodiment, the trigger part 43 is designed as a conical structure, and the end of the sliding hole 41 near the spring 45 is also designed as a conical hole structure. The conical hole structure of the sliding hole 41 matches the conical structure of the trigger part 43. The trigger switch 46 is fixedly installed on the inner wall of the conical hole of the sliding hole 41 to avoid jamming between the trigger part 43 and the sliding hole 41. This allows the trigger part 43 to quickly squeeze the trigger switch 46 and issue an alarm when the connecting wire harness 1 is pulled to the threshold.

[0033] Furthermore, power supply 48 uses a button cell battery.

[0034] In this embodiment, the power supply 48 uses a button battery. Button batteries are small in size, low in cost, and can well meet the warning effect of the buzzer 47.

[0035] When medical staff, family members, or patients accidentally trip over or pull on the connecting harness 1 of the medical device 5 while walking around, the connecting harness 1 is violently pulled. The connecting harness 1, through the fixed shell 31, pulls the elastic element 2 to extend in the direction of the pull, which plays a certain role in buffering and avoiding the safety hazards caused by the violent pulling of the medical device 5 wiring harness. During this process, the elastic element 2 pulls the trigger part 43 through the sliding pin 42 to move continuously into the sliding hole 41. The limit cap 44 squeezes the spring 45, and the trigger part 43 on the sliding pin 42 gradually enters into the sliding hole 41. When the squeezing force on the spring 45 reaches the set safety threshold, the trigger part 43 contacts the trigger switch 46 in the sliding hole 41 and squeezes the trigger switch 46. The trigger switch 46 activates the buzzer 47 to sound an alarm, thereby achieving the effect of early warning and further avoiding the safety hazards caused by the violent pulling of the medical device 5 wiring harness.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
