Description

Technical Field

[0001] This application relates to the field of heart failure detection equipment technology, and more specifically, to an ultrasonic probe for heart failure detection. Background Technology

[0002] An ultrasound probe is a key component of ultrasound diagnostic equipment. It utilizes the physical properties of ultrasound waves to detect the internal structure and functional state of the human body by emitting and receiving these waves. In heart failure detection, an ultrasound probe can assess the size, shape, valvular function, and hemodynamic parameters of the heart in real time and non-invasively, providing accurate scientific evidence for medical diagnosis.

[0003] The existing ultrasonic probes use an integrated connection structure between the detection end, interface end and signal transmission line. This causes the signal transmission line to be subjected to torsional torque transmitted from the detection end and interface end during operation, resulting in the signal transmission line being twisted. Long-term twisting may cause fatigue and damage to the external protective structure of the signal line, thereby exposing the internal circuitry. Furthermore, excessive twisting may physically compress the internal circuitry of the signal transmission line, leading to internal circuitry breakage or reduced signal transmission efficiency.

[0004] Therefore, we propose an ultrasound probe for heart failure detection to address the existing problems. Utility Model Content

[0031] like Figures 1 to 7 As shown, an ultrasound probe for heart failure detection includes a signal line 1. One end of the signal line 1 has a first connector 11, and the other end has a second connector 14. A first connecting ring 2 is rotatably mounted on the first connector 11, and a sleeve 3 is rotatably mounted on the outer periphery of the first connecting ring 2. A contact 4 is provided on the sleeve 3. A second connecting ring 6 is rotatably mounted on the second connector 14. The second connector 14 is movably connected to the heart failure detection device body via the second connecting ring 6. In use, the first connector 11 and the second connector 14 are respectively located at both ends of the signal line 1. The first connecting ring 2 is rotatably mounted on the first connector 11, and the sleeve 3 is rotatably mounted on the first connecting ring 2. The sleeve 3 has a contact 4, such that the contact... 4 can rotate freely relative to the first connector 11 with the sleeve 3, more flexibly adapting to different detection angles, allowing the contact 4 to be flexibly adjusted at multiple angles during heart failure detection. At the same time, it ensures that the connection end between the signal line 1 and the connector will not be subjected to excessive force and twisting, causing fatigue and damage to the outer shell. The second connector 14 is rotatably mounted with the second connecting ring 6. The second connector 14 is movably inserted into the heart failure detection device body through the second connecting ring 6. When the second connector 14 is inserted into the interface of the heart failure detection device body, the second connector 14 can rotate freely relative to the interface of the heart failure detection device body through the second connecting ring 6, so that the connection end between the signal line 1 and the second connector 14 will not be subjected to excessive force and twisting, causing damage.

[0032] Furthermore, the outer periphery of the first connecting ring 2 is provided with at least one annular groove 21, and the annular groove 21 is provided with a plurality of first mounting holes 22 penetrating the side wall of the first connecting ring 2. The first mounting holes 22 are provided with first balls 23. The outer periphery of the first connector 11 is provided with at least one first rolling groove 112 corresponding to the position of the annular groove 21. The first balls 23 are rolled in connection with the first rolling groove 112. In use, the outer periphery of the first connecting ring 2 is provided with an annular groove 21 and first mounting holes 22, and the mounting holes are provided with first balls 23. The outer periphery of the first connector 11 is provided with a first rolling groove 112 corresponding to the annular groove 21. The first balls 23 roll in the first rolling groove 112 to realize the rotational connection of the first connecting ring 2 relative to the first connector 11. The first balls 23 are provided so that the frictional resistance is smaller and the rotation is smoother during the rotation of the first connecting ring 2 relative to the first connector 11.

[0033] Furthermore, a collapsible ring 24 is also installed on the outer periphery of the annular groove 21. The inner ring of the collapsible ring 24 is in rolling connection with the first ball 23, and the outer periphery of the collapsible ring 24 is in an interference fit with the inner wall of the sleeve 3. In use, the interference fit between the collapsible ring 24 and the sleeve 3 can prevent the sleeve 3 from slipping. The collapsible ring 24 deforms when subjected to abnormal torque to provide overload protection. When disassembling the sleeve 3 and the first connecting ring 2, the sleeve 3 and the first connecting ring 2 are pulled outward as a whole, so that when the first ball 23 is disengaged from the first rolling groove 112, it is subjected to a reverse force applied by the first rolling groove 112, and reverses its movement. Force is transmitted through the first ball 23 to the collapsible ring 24, causing the collapsible ring 24 to be compressed, thereby allowing the first ball 23 to disengage from the first rolling groove, and thus causing the sleeve 3, the first connecting ring 2, and the first connector 11 to separate. After the sleeve 3, the first connecting ring 2, and the first connector 11 are separated, one end of the first ball 23 loses the support of the first rolling groove 112 and can move freely in the first mounting hole 22, allowing the collapsible ring 24 to contract relative to the end in contact with the first ball 23, causing the interference fit between the first connecting ring 2 and the sleeve 3 to fail, and thus the first connecting ring 2 and the sleeve 3 can be separated.

[0034] Furthermore, the first connector 11 has a slot 111 at its axial front end, and the sleeve 3 has an electrode 31 inside that is inserted into and connected to the slot 111. The other end of the electrode 31 is electrically connected to the contact 4. In use, the axial insertion between the slot 111 and the electrode 31 can achieve rolling contact, and signal transmission can continue even when rotating.

[0035] Furthermore, the contact 4 is fixedly installed on the outer end of the sleeve 3. A suction cup 5 is also provided around the outer periphery of the connection end between the contact 4 and the sleeve 3. The diameter of the suction cup 5 gradually expands from the root of the connection end between the contact 4 and the sleeve 3 to the other end. When in use, the suction cup 5 is made of medical silicone material and is adsorbed onto human skin by negative pressure to perform heart failure detection.

[0036] Furthermore, a first limiting ring 12 is provided between the first connector 11 and the connection end of the signal line 1. In use, it is used to limit the connection position between the first connecting ring 2 and the first connector 11 and prevent the first connecting ring 2 from sliding axially relative to the signal line 1.

[0037] Furthermore, the second connector 14 is provided with at least one second rolling groove 141 that can engage with the second connecting ring 6, and an expansion ring 142 is installed on the outer periphery of the second rolling groove 141.

[0038] Furthermore, the second connecting ring 6 is provided with at least one second mounting hole 61 corresponding to the second rolling groove 141. A second ball bearing 62 is provided in the second mounting hole 61. One end of the second ball bearing 62 passes through the second mounting hole 61 and is rolled between it and the expansion ring 142. In use, the second ball bearing 62 rolls on the expansion ring 142, allowing the second connecting ring 6 to rotate freely relative to the second connector 14. The second expansion ring 142 provides radial outward support to the second ball bearing 62, so that when the second connector 14 is connected to the heart failure detection device body through the second connecting ring 6, the other end of the second ball bearing 62 abuts against the inner wall of the interface of the heart failure detection device body, thereby forming a more stable connection structure. This also allows the second connecting ring 6 to rotate freely relative to the second connector 14 and the heart failure detection device body, preventing the signal line 1 from twisting due to the torsional torque at the connection end between the signal line 1 and the second connector 14.

[0039] Furthermore, the second connector 14 has a contact 15 at its axial front end. The contact 15 makes contact with the heart failure detection device body and conducts electricity. In use, the contact 15 is plated with a gold-nickel alloy and is connected to the contact sensing circuit in the interface of the heart failure detection device body to conduct electricity and realize signal transmission.

[0040] Furthermore, a second limiting ring 13 is provided between the second connector 14 and the signal line 1 to limit the installation position of the second connecting ring 6 and prevent the second connecting ring 6 from sliding axially relative to the signal line 1.

[0041] The above-described specific embodiments are merely preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above-described specific embodiments.
