[0002] A portable blood gas and biochemistry analyzer with anti-detachment wiring is an important piece of equipment in the medical testing field, mainly used to quickly and accurately measure parameters such as gases, electrolytes, and metabolites in blood. In emergency rooms, ICUs, and bedside testing scenarios, portable blood gas analyzers need to be frequently moved and used, thus placing high demands on the reliability of the connection, ease of operation, and protective performance. However, traditional wiring connections often suffer from problems such as loosening and detachment, affecting testing efficiency and accuracy, necessitating a more reliable anti-detachment connection structure.

[0003] In existing technologies, the wiring connections of blood gas and biochemistry analyzers typically employ plug-in interfaces or threaded fastening structures. Plug-in interfaces rely on simple plug-in mating for connection, while threaded fastening enhances stability through rotational locking. Some devices also use elastic clips or magnetic structures for additional fixation, but these methods mostly rely on a single mechanical structure or additional auxiliary components, and loosening may still occur during frequent plugging and unplugging or movement.

[0004] However, existing pluggable interfaces are prone to accidental detachment when the device is moved or subjected to external force, leading to detection interruptions or data loss. This instability can affect treatment efficiency, especially in emergency medical scenarios. Therefore, there is an urgent need for a connection structure that can balance quick plugging / unplugging with anti-detachment functionality to improve device reliability and ease of use.

[0008] Furthermore, a fixed column is fixedly connected to the outer wall of the analyzer body, and a rotating rod is rotatably connected to the outer wall of the fixed column. A protective component is provided inside the rotating rod.

[0009] Furthermore, the protective component includes a fixed sleeve, the outer wall of which is fixedly connected to the inside of the rotating rod, a sliding sleeve slidably connected to the inner wall of the fixed sleeve, a threaded rod fixedly connected to the outer wall of the sliding sleeve, and a handle two fixedly connected to one end of the threaded rod.

[0010] Furthermore, the outer wall of the threaded rod is threaded to the inner wall of the fixed sleeve, and the second handle is located below the fixed sleeve.

[0011] Furthermore, the outer wall of the ball is slidably connected to the inner wall of the connector, and the outer wall of the partition is slidably connected to the inner wall of the connector.

[0012] Furthermore, one end of the spring is fixedly connected to the outer wall of the partition, and the other end of the spring is fixedly connected to the inner wall of the connector.

[0013] Furthermore, the handle is disposed on the outer wall of the connector, and the outer wall of the sliding rod is slidably connected to the inner wall of the connector.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-5 The present invention provides an embodiment of a portable blood gas and biochemistry analyzer with anti-detachment circuit, comprising an analyzer body 1, a connector 2 fixedly connected to the upper surface of the analyzer body 1, which serves as a fixed interface and cooperates with a connector 3 to achieve circuit connection, a connector 3 slidably connected to the inner wall of the connector 2, which can be slidably inserted into the connector 2 to achieve quick docking, and a limit component is provided on the inner wall of the connector 3.

[0027] The limiting component includes a retaining ball 6, which mechanically locks the ball in a groove to prevent it from falling off. The outer wall of the retaining ball 6 is slidably connected to the inner wall of the connector 2 3. A partition 7 is fixedly connected to the outer wall of the connector 2 3, which transmits operating force in conjunction with the sliding rod 9. The sliding rod 9 is fixedly connected to the outer wall of the partition 7, which transmits the operating force of the handle 10 to drive the partition 7 to move. One end of the sliding rod 9 is fixedly connected to the handle 10, which provides an external force operation point to realize connection and separation. A spring 8 is sleeved on the outer wall of the sliding rod 9 to provide elastic clamping force to keep the retaining ball 6 in the engaged state. A groove 15 is opened inside the connector 2 to provide a movement guide space for the sliding rod 9.

[0028] Specifically, firstly, align connector 2 (3) with the interface of connector 1 (2). The sliding contact between the two enables a quick connection. During the connection process, the limiting component plays a crucial role in ensuring a stable connection. Specifically, when connector 2 (3) is fully inserted into connector 1 (2), the retaining ball (6) slides under the guidance of the inner wall of connector 2 (3), eventually locking into the corresponding groove inside connector 1 (2), forming a reliable mechanical locking structure. This effectively prevents accidental dislodgement due to equipment movement or external forces. The partition 7 and the sliding rod 9 form a linkage mechanism. Under the elastic clamping force provided by the spring 8, the retaining ball 6 remains in a stable locked state. When disassembly is required, the operator simply pulls the handle 10 outwards, causing the sliding rod 9 and partition 7 to move, compressing the spring 8, thus disengaging the retaining ball 6 from the groove and achieving quick separation of connector 2 (3).

[0029] Reference Figures 1-5 The analyzer body 1 has a fixed column 4 fixedly connected to its outer wall, supporting a rotating rod 5 to achieve rotation. The rotating rod 5 is rotatably connected to the outer wall of the fixed column 4, allowing for rotatable storage to save space. A protective component is installed inside the rotating rod 5, including a fixed sleeve 12, which provides an installation base for a sliding sleeve 11. The outer wall of the fixed sleeve 12 is fixedly connected to the inside of the rotating rod 5, and the sliding sleeve 11 is slidably connected to the inner wall of the fixed sleeve 12, covering and protecting the connector 2 through telescopic movement. A threaded rod 13 is fixedly connected to the outer wall of the sliding sleeve 11, allowing adjustment of the position of the sliding sleeve 11 through threaded transmission. One end of the threaded rod 13 is fixedly connected to a hand... Handle 2 14 provides a rotary operating point to control the movement of the threaded rod 13. The outer wall of the threaded rod 13 is threadedly connected to the inner wall of the fixed sleeve 12. Handle 2 14 is located below the fixed sleeve 12. The outer wall of the ball 6 is slidably connected to the inner wall of the connector 1 2. The outer wall of the partition 7 is slidably connected to the inner wall of the connector 1 2. One end of the spring 8 is fixedly connected to the outer wall of the partition 7, and the other end of the spring 8 is fixedly connected to the inner wall of the connector 1 2. Handle 1 10 is located on the outer wall of the connector 1 2. The outer wall of the sliding rod 9 is slidably connected to the inner wall of the connector 1 2. The rotating rod 5 is attached to the outer wall of the analyzer body 1. Connector 2 3 is located above the analyzer body 1.

[0030] Specifically, the sliding sleeve 11 forms a threaded connection structure with the fixed sleeve 12 through the threaded rod 13. The operator can precisely adjust the extension length of the sliding sleeve 11 by rotating the handle 14, so that when the equipment is not in use, the sliding sleeve 11 can completely cover the connector 2, effectively preventing dust from entering or mechanical damage. The rotating rod 5 adopts a rotatable design, which can be completely attached to the outer wall of the analyzer body 1 for storage when not in use, saving space and making it easy for users to carry. While ensuring the reliability of the connection, the portability and protection of the equipment are fully considered, making it particularly suitable for medical testing scenarios that require frequent movement.

[0031] Working principle: When using the portable blood gas and biochemistry analyzer with anti-detachment circuit, firstly, the circuit is quickly connected by the sliding engagement of connector 1 2 and connector 2 3. The limiting component ensures a stable connection. When connector 2 3 is inserted into connector 1 2, the retaining ball 6 slides on the inner wall of connector 2 3 and locks into the corresponding groove of connector 1 2, forming a mechanical lock to prevent accidental detachment. The partition 7 and the sliding rod 9 are linked, and the spring 8 provides elastic clamping force to keep the retaining ball 6 in a stable locked state. If disassembly is required, the sliding rod 9 is pulled by the handle 1 10, which drives the partition 7 to compress the spring 8, causing the retaining ball 6 to disengage from the groove, thus separating connector 2 3 and achieving quick disassembly and assembly.

[0032] In addition, the sliding sleeve 11 is threadedly connected to the fixed sleeve 12 via the threaded rod 13. The extension and retraction length of the sliding sleeve 11 can be adjusted by rotating the handle 14, thereby protecting the connector 2 when the device is not in use. The rotating rod 5 can be stored close to the outer wall of the analyzer body 1 for easy carrying by the user, taking into account both convenience and protection.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
