Description

Technical Field

[0001] This invention relates to the field of connecting wires, and particularly to a connecting wire with stable connection. Background Technology

[0002] A pulse oximeter probe, or simply pulse oxygen probe, is an instrument used to measure the oxygen concentration in human blood, i.e., blood oxygen saturation. The sensor consists of two light-emitting diodes (LEDs) and one photoelectric diode. It allows for timely monitoring of blood oxygen levels during surgical procedures or in the care of critically ill patients. The existing patent number CN202021591855.3 describes a disposable pulse oximeter probe connector. While this reduces material waste and allows for reusable probe connectors, the parts in contact with the human body are disposable, meeting clinical requirements and effectively saving material costs. However, the connecting plate used for fixing the probe is prone to accidental contact, making the disposable pulse oximeter probe susceptible to breakage due to external force during use, ultimately affecting its normal operation. Therefore, a more stable connector is needed to solve this problem. Summary of the Invention

[0003] The main objective of this invention is to provide a stable connecting cable that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A stable connection cable includes a first device connection cable and a second device connection cable. A fixing clamp is installed on the second device connection cable, and a connection structure is installed on the first device connection cable. Two push springs are symmetrically installed inside the connection structure. Two connection cable fixing devices are slidably installed inside the connection structure on the rear side of the two push springs. The connection cable fixing device includes a mounting base structure, fixing pins, and a pulling plate structure. There are four fixing pins symmetrically arranged at the rear end of the mounting base structure, and two pulling plate structures symmetrically arranged at the left and right ends of the mounting base structure.

[0006] Preferably, the connecting structure has a device storage cavity, and the tail end of the connecting structure has a wire hole structure that passes through the tail end of the connecting structure and the device storage cavity. The connecting structure has an insertion slot that passes through the upper and lower ends of the connecting structure and the device storage cavity. The connecting structure has a sliding limiting groove that passes through the left and right ends of the connecting structure and the device storage cavity. The first end of the connecting structure has a first wire groove, which is also located at the upper end of the connecting structure and passes through the upper end and the first end of the connecting structure and the device storage cavity. Two mounting guide posts are symmetrically arranged on the front inner wall of the device storage cavity. The two mounting guide posts are symmetrically arranged on the left and right sides of the first wire groove, and the two mounting guide posts have a connecting structure that is integrally formed.

[0007] Preferably, the tail end of the first device connection line is connected to a probe connector, and a mounting plate is sleeved on the first device connection line. The mounting plate is fixedly sleeved on the first device connection line by adhesive, and the mounting plate is located in a device storage cavity opened within the connection structure.

[0008] Preferably, the first end of the connection cable of the second device is connected to the probe body.

[0009] Preferably, the fixing clamp has a mounting through hole that passes through both the front and rear ends of the fixing clamp. The fixing clamp also has four symmetrical fixing holes that pass through both the front and rear ends of the fixing clamp. The four fixing holes are symmetrically located outside the mounting through hole. The fixing clamp is fitted onto the second device connection line through the mounting through hole. The fixing clamp and the second device connection line are fixedly connected by adhesive. The fixing clamp is installed in the insertion slot and device storage cavity on the connecting structure.

[0010] Preferably, both push springs are located within the device receiving cavity opened in the connecting structure, and the two push springs are respectively sleeved on two mounting guide posts symmetrically arranged within the device receiving cavity.

[0011] Preferably, the connecting wire fixing device is installed in the device receiving cavity opened within the connecting structure. The upper end of the mounting base structure has a second wire groove. The mounting base structure has two symmetrically opened guide post insertion holes, which pass through the front and rear ends of the mounting base structure. The two guide post insertion holes are symmetrically opened on the left and right sides of the second wire groove. The mounting base structure is slidably installed on the mounting guide posts through the two symmetrically opened guide post insertion holes. The two pulling plate structures are respectively located in two symmetrically opened sliding limiting grooves at the left and right ends of the connecting structure. The outer ends of the two pulling plate structures each have a finger slot. The two pulling plate structures can slide within the two sliding limiting grooves. The four fixing pins are respectively inserted into four symmetrically opened fixing pin holes on the fixing plate. The mounting base structure, the pulling plate structure, and the fixing pins are integrally formed.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] By setting up a connection structure, the connection point between the No. 1 and No. 2 device connection lines, as well as the connection line fixing device used to secure the No. 2 device connection line, can be protected. This prevents the connection line fixing device from being moved by external force, and ultimately prevents the No. 1 and No. 2 device connection lines from becoming disconnected during use of the disposable pulse oximeter probe. By setting up the connection line fixing device and fixing clamp, they can cooperate with each other to facilitate the quick fixing and disassembly of the No. 2 device connection line. By setting up a push spring, the connection line fixing device can be easily fixed, thus preventing the connection line fixing device from being easily moved by external force when it is not needed.

The first wire groove 16 connects the upper end and the first end of the connecting structure 4 to the device storage cavity 12. Two mounting guide posts 17 are symmetrically arranged on the front inner wall of the device storage cavity 12, symmetrically positioned on the left and right sides of the first wire groove 16. The two mounting guide posts 17 and the connecting structure 4 are integrally formed. A probe connector 7 is connected to the tail end of the first device connecting line 1. A mounting plate 8 is sleeved on the first device connecting line 1, and the mounting plate 8 is fixedly fitted onto the first device connecting line 1 with adhesive. The mounting plate 8 is located inside the device storage cavity 12 within the connecting structure 4. The second device... The first end of the connecting cable 2 is connected to the probe body 9. To facilitate the quick fixing and disassembly of the connecting cable 2, a connecting cable fixing device 6 and a fixing clamp 3 are provided. The fixing clamp 3 has a mounting through hole 10 that passes through both the front and rear ends of the fixing clamp 3. The fixing clamp 3 has four symmetrical fixing holes 11 that pass through both the front and rear ends of the fixing clamp 3.

Both push springs 5 ​​are located in the device storage cavity 12 opened within the connecting structure 4, and the two push springs 5 ​​are respectively sleeved on two symmetrically arranged mounting guide pins 17 within the device storage cavity 12.

[0022] It should be noted that this invention is a stable connecting cable. In use, connecting cable 1 (device number 1) and connecting cable 2 (device number 2) can be connected together. The method is as follows: First, pull the pull plate structure 22 on the connecting cable fixing device 6 forward, causing the connecting cable fixing device 6 to move forward. During the forward movement of the connecting cable fixing device 6, the mounting base structure 18 compresses the push spring 5. After the connecting cable fixing device 6 has moved a certain distance forward, the fixing clamp 3 installed on the connecting cable 2 is placed into the insertion slot 14 opened on the connecting structure 4. At this time, a portion of the connecting cable 2 will be within the device receiving cavity 12, the first cable slot 16, and the second cable slot 19. Then, the pull plate structure 22 on the connecting cable fixing device 6 is released, and under the push of the push spring 5, the connection... The wire fixing device 6 will move backward, and the fixing pin 21 on the wire fixing device 6 will eventually slide into the fixing hole 11 on the fixing clamp 3, thus completing the connection between the first device connection line 1 and the second device connection line 2. After the device is used up, the probe body 9, the second device connection line 2, and the fixing clamp 3 can be removed and discarded. The method is to pull the pull plate structure 22 on the wire fixing device 6 forward, so that the wire fixing device 6 moves forward. During the forward movement of the wire fixing device 6, the mounting base structure 18 will compress the push spring 5. After the wire fixing device 6 moves forward a certain distance, the fixing pin 21 will disengage from the fixing hole 11 on the fixing clamp 3. At this time, the fixing clamp 3 can be removed from the slot 14 on the connecting structure 4.
