[0002] Portable medical devices can monitor various physiological parameters in real time, such as body temperature, ECG, heart rate, blood oxygen, blood pressure, blood sugar, and sleep quality, helping users understand their health status and detect potential health risks. The most important aspect of portable medical devices is portability. While ensuring performance, the device needs to be as small as possible. Common portable medical devices on the market are either small with few functions or feature-rich but bulky, making them very inconvenient to use. Secondly, the accessories used with portable medical devices are also crucial. The design of accessories directly affects the user experience. Common portable devices on the market often focus on the device itself, neglecting the design of accessories. Smaller portable devices on the market generally only have one or two functions, which is incomplete. If other parameters need to be measured, the device needs to be switched, which is very time-consuming. Common portable devices on the market often reduce some protective measures due to space constraints, such as omitting defibrillation resistors, narrowing isolation bands, and not adding cushioning to the air pump valves. While this does save space, it affects the overall performance of the device. Utility Model Content

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0031] This utility model provides a parameter connector, please refer to... Figures 1-8 The connector includes a socket 10 and a plug 20. The plug 20 includes an ECG and blood oxygenation plug 210 and a body temperature and blood pressure ...
[0032] Based on the parameter connector in the above embodiments, the plug 20 includes an ECG / oxygenation plug 210 and a body temperature / IBP plug 220. ECG parameters and oxygenation parameters are integrated into the ECG / oxygenation plug 210, while body temperature parameters and IBP parameters are integrated into the body temperature / IBP plug 220. Therefore, the number of corresponding sockets 10 on the portable medical device is reduced from four to two, allowing for a more miniaturized portable medical device and achieving portability.
[0033] In medical devices, IBP usually refers to Invasive Blood Pressure Monitoring. This is a method of directly measuring blood pressure within an artery by inserting a catheter through arterial puncture. An IBP monitoring system includes an electronic system and a fluid-filled catheter system. A catheter is inserted into the artery through punctures at sites such as the radial or femoral artery and connected to a pressure sensor and monitoring device. The sensor is typically positioned at the level of the right atrium to correct for the effects of gravity and ensure accurate measurements.
[0034] In some specific embodiments, the socket 10 and the plug 20 are electrically connected via a pogo pin 230.
[0035] This utility model uses a Pogopin 230 connector. A Pogopin is a precision connector composed of three basic components: a plugger, a tube, and a spring. It is widely used in electronic equipment for transmitting current or signals. Compared to traditional pin terminals, this connector can be made smaller, and the Pogopin 230 technology is mature and reliable.
[0036] In some specific embodiments, the plug 20 includes a frame 240, a pogo pin 230, a cable, an inner shell 250, and an outer shell 260. The pogo pin 230 passes through the frame 240, the inner shell 250 is sealed to the frame 240, the outer shell 260 is fitted over the inner shell 250 and connected to the frame 240, and the cable is bundled in the inner shell 250 and electrically connected to the pogo pin 230 in a one-to-one correspondence.
[0037] In this embodiment, the pogo pin 230 passes through the frame 240 to connect with the socket 10. One end of the pogo pin 230 is electrically connected to the cable, which is then passed through the inner shell 250. The inner shell 250 is generally open at both ends. The cable passes through the inner shell 250, with one end of the inner shell 250 sealed to the frame 240 and the other end sealed to the outer shell 260. The outer shell 260 is finally fitted onto the inner shell 250 and connected to the frame 240. This arrangement ensures the waterproof sealing of the plug 20.
[0038] Generally, the inner shell 250 and outer shell 260 are made by using a die-casting method, which can effectively enhance the waterproof performance and bending performance of the plug 20.
[0039] In some specific embodiments, the ECG pulse oximeter plug 210 also includes an anti-defibrillation resistor 270, with its two ends connected to a pogo pin 230 and a cable, respectively.
[0040] The anti-defibrillation resistor 270 is a special resistive element primarily used in medical devices, especially electrocardiogram (ECG), electroencephalogram (EEG), and defibrillators, to protect the equipment and patients from damage caused by high-energy defibrillation pulses. This is mainly for monitoring the patient's electrocardiographic status in case defibrillation is necessary. However, defibrillators generate high-voltage current, which can travel through cables into portable medical devices, potentially causing damage.
[0041] In existing technologies, the defibrillator 270 is typically mounted on the connecting wire. Mounting the defibrillator 270 on the wire makes the overall appearance of the wire less aesthetically pleasing. Furthermore, the wire frequently needs to be bent, making the defibrillator 270 susceptible to damage. In this embodiment, the defibrillator 270 is integrated into the plug 20. This ensures that the overall cross-sectional diameter of the connecting wire to the plug 20 remains consistent. Additionally, the defibrillator 270 within the plug 20 avoids potential risks such as bending or being stepped on. These features significantly improve the safety of the treatment device.
[0042] In some specific embodiments, the plug 20 further includes a multi-function plug 280, the socket 10 includes a multi-function socket 110, the multi-function plug 280 includes a magnetic element 281 to fix the multi-function plug 280 and the multi-function socket 110 by magnetic attraction, and the multi-function socket 110 integrates a charging interface.
[0043] The multi-function plug 280 integrates various other functions, such as charging and data transmission. When paired with the multi-function socket 110, the multi-function plug 280 can not only power portable medical devices but also export and import information integrated into the portable medical devices for analysis.
[0044] The magnetic element 281 serves as a quick connection device. It can be installed on the multi-function socket 110 or the multi-function plug 280.
[0045] It should be noted that portable medical devices generally have built-in batteries and can be powered by either an external power source or the built-in battery. The multi-functional socket 110 in this embodiment can power the portable medical device and also facilitate data transmission. This makes the portable medical device smaller, more integrated, and easier to carry and use.
[0046] Since the multi-function plug 280 is plugged and unplugged more frequently, the magnetic connection between the multi-function plug 280 and the multi-function socket 110 can improve the user's ease of use.
[0047] In some specific embodiments, the socket 10 includes a board 120, a spring 130, a mounting bracket 140, and an electrical contact 150. The board 120, the spring 130, and the mounting bracket 140 are stacked in sequence, and the electrical contact 150 passes through the board 120, the spring 130, and the mounting bracket 140. The spring 130 is used to engage with the plug 20.
[0048] When plug 20 is inserted into socket 10, plug 20 is electrically connected to electrical contact 150 via pogo pin 230. At this time, spring 130 begins to hold plug 20, thereby strengthening the connection between socket 10 and socket 20.
[0049] The main functions of the board 120 and the mounting bracket 140 are to hold the spring 130 in place, thereby fixing the spring 130. Generally, the board 120, spring 130, and mounting bracket 140 are fixed by screws.
[0050] In some specific embodiments, the outer diameter of the front end of the plug 20 should be larger than the outer diameter of the rear end.
[0051] When the plug 20 is inserted into the socket 10, the front end of the plug 20 can be flush with the outer shell 260 of the portable medical device, thereby increasing the tightness and aesthetics of the connection between the plug 20 and the socket 10.
[0052] In some specific embodiments, the plug 20 has anti-slip texture 291 and guide markings 292.
[0053] In this embodiment, the anti-slip texture 291 increases the friction of the plug 20, thereby facilitating insertion and removal. The guide marks help users identify the insertion direction of the plug 20 and distinguish the front and back of the plug 20.
[0054] The outer shell 260 adopts an ergonomic design with an arc-shaped end, which facilitates plugging and unplugging and enhances the bending performance of the plug 20.
[0055] In some specific embodiments, a connector 30 is also included. The connector 30 includes a base 310, a ball bearing 320, a bracket 330, a flexible sleeve 340, and a connector 350. The bracket 330 is provided with a plurality of mounting holes 3310 smaller than the diameter of the ball bearing 320, and the ball bearing 320 is mounted in the mounting holes 3310. The flexible sleeve 340 is sleeved on the bracket 330, and the base 310 is sleeved on the flexible sleeve 340 and has a spiral groove 3110. The connector 350 has a limiting protrusion 3510, which can be screwed into the spiral groove 3110.
[0056] In this embodiment, connector 30 is primarily an NIBP connector 30. The NIBP connector 30 is a connecting component used in non-invasive blood pressure (NIBP) monitoring devices. Its main function is to connect the blood pressure cuff to the monitor or other measuring devices to achieve blood pressure signal transmission and measurement. The design and quality of the NIBP connector 30 directly affect the accuracy and reliability of blood pressure measurement. A high-quality NIBP connector 30 ensures good airtightness, reduces signal interference, and thus improves the accuracy of monitoring results.
[0057] For blood pressure monitoring, inflation is usually required, thus the sealing of the connector 30 is important. In this embodiment, the ball bearing 320 is generally a steel ball, which protrudes from the bracket 330 and is then tightly wrapped by the flexible sleeve 340. The flexible sleeve 340 is then placed into the base 310, where the steel ball engages with the positioning groove on the base 310, and the tight fit between the base 310 and the bracket 330 is achieved by compressing the surrounding flexible sleeve 340.
[0058] The connector 350 is inserted into the base 310 and abuts against the flexible sleeve 340. Gas passes through the base 310, the flexible sleeve 340, and the connector 350 in sequence. The limiting protrusion 3510 of the connector 350 is screwed into the edge opening of the spiral groove 3110, thereby realizing the connection and fixation between the connector 350 and the base 310 and ensuring the airtightness and tightness of the connection.
[0059] In some specific embodiments, the base 310 is made of metal.
[0060] The base 310 can be made of plastic or metal. If the base 310 is made of metal and has a thinner wall, it can effectively reduce the volume of the connector 30. The connector 30 is assembled without gluing, ultrasonic or other processes, which helps to improve production efficiency.
[0061] Portable medical devices generally consist of a main unit and accessories. The accessories are mainly connected to the corresponding body part of the patient to collect physiological parameters, such as electrocardiogram, body temperature, and blood pressure.
[0062] In this utility model, the socket 10 is fixed on the main unit, while the plug 20 is generally used with accessories to connect the accessories to the main unit.
[0063] For portable medical devices, smaller size is more convenient. The parameter connector in this invention reduces the number of sockets 10 and plugs 20 on the portable medical device, thereby simplifying its size. It also reduces the number of accessories, preventing cables from becoming tangled. Finally, due to the reduced number of plugs 20, users can quickly insert the plugs 20 into the corresponding positions in the sockets 10, reducing trial-and-error time.
[0064] Please refer to Figure 1 and Figure 2 Both socket 10 and connector 30 are located on the same end of the portable medical device. Having socket 10 and connector 30 on one end of the portable medical device, and multi-function socket 110 on the other end, facilitates user connection and prevents accessories from becoming tangled.
[0065] Finally, it should be noted that a rubber ring is provided on the socket 10 or the plug 20 so that the connection between the plug 20 and the socket 10 can achieve a sealing and waterproof effect.
[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0067] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
