[0024] Embodiments of the present invention will now be described with reference to the accompanying drawings.

[0025] Example

[0026] The specific embodiments of this utility model are as follows: Figure 1-2 As shown, a blood pressure monitoring device capable of collecting blood includes a device body 1, with an infusion tube 12 connected to the device body 1. In this embodiment, half of the infusion tube 12 is located inside the device body 1, and the other half extends to the outside of the device body 1. In use, the infusion tube 12 is connected to the patient's artery via an infusion needle or other medical device, allowing blood from the patient's artery to enter the device body through the infusion tube 12.

[0027] In this device, the main body 1 contains a first cavity 101 and a second cavity 102. The first cavity 101 houses a pressure sensor 11, and its bottom is connected to an infusion tube 12. The pressure sensor 11 has a detection end and can detect the pressure within the first cavity 101, thus enabling blood pressure monitoring. The second cavity 102 has an open top and an electrically controlled valve 16 at its bottom. In this embodiment, the electrically controlled valve 16 is connected to a controller within the main body of the device, and the controller is also connected to the pressure sensor 11. The inlet of the electrically controlled valve 16 is connected to the infusion tube 12, and its outlet is connected to the opening of a storage bottle 13 detachably inserted into the second cavity 102. The controller can control the opening and closing of the electrically controlled valve 16, enabling blood collection in conjunction with the storage bottle 13.

[0028] By incorporating a replaceable storage bottle 13 and an electrically controlled valve 16, the storage bottle 13 can be removed independently after blood collection. The storage bottle 13 can be directly fitted onto the second cavity 102 of the main body 1 as a container for collecting blood, reducing medical consumables and lowering medical costs for patients. Simultaneously, the storage bottle 13, as a container for blood testing, can also be easily applied to other blood parameter testing equipment—such as centrifuges—facilitating the testing of other blood parameters. Furthermore, the detachable and replaceable design of the storage bottle 13 allows for reuse, significantly reducing the use of medical consumables.

[0029] In this device, to enable the detachable installation of the storage bottle 13 within the second cavity 102, a limiting protrusion 131 is provided on the outer wall of the storage bottle 13 around its axis, and a limiting groove 103 corresponding to the limiting protrusion 131 is provided on the inner wall of the second cavity 102. The limiting protrusion 131 and the limiting groove 103 effectively limit the storage bottle 13 from the inner wall of the second cavity 102, thereby preventing the storage bottle 13 from detaching during blood pressure monitoring and blood collection, and thus preventing the storage bottle 13 from contaminating the surgical environment.

[0030] In this embodiment, the limiting protrusion 131 and the limiting groove 103 are in a snap-fit ​​engagement, and the lower part of the outer edge of the limiting protrusion 131 is provided with a guide slope. Providing a limiting protrusion 131 with a guide slope on the outer surface of the storage bottle 13 facilitates the snap-fit ​​installation of the storage bottle 13. Of course, in actual production, the limiting protrusion 131 and the limiting groove 103 can also be connected by a threaded engagement. A threaded engagement can maintain a stable fit between the storage bottle 13 and the second cavity 102. Both installation methods have their advantages.

[0031] In addition, to prevent blood from leaking out of the mouth of the storage bottle 13 during blood collection, a sealing assembly 14 for sealing the mouth of the storage bottle 13 is provided on the inner wall of the second cavity 102. Specifically, the sealing assembly includes two opposing claws 141 disposed on the inner wall of the second cavity 102 and capable of clamping each other, and a sealing ring 15 is fitted over the mouth of the storage bottle 13. By squeezing the two claws 141, the sealing ring 15 can be tightly pressed against the outer edge of the storage bottle 13, thereby preventing blood from flowing out from the connection between the storage bottle 13 and the electrically controlled valve 16. In this embodiment, to drive the claws 141, the sealing assembly also includes two motors 142 corresponding one-to-one with the claws 141, and the power output end of the motors 142 is connected to the claws 141 in a transmission connection. At the same time, to prevent blood from flowing out when the storage bottle 13 is removed, an anti-backflow valve can also be provided inside the mouth of the storage bottle 13.

[0032] The present invention has been described above in conjunction with the preferred embodiments, but the present invention is not limited to the embodiments disclosed above, but should cover various modifications and equivalent combinations made in accordance with the essence of the present invention.
