[0002] Femoral artery puncture is a commonly used interventional diagnosis and treatment technique in clinical practice, and is widely used in the diagnosis and treatment of cardiovascular diseases and various other medical procedures. However, during the actual operation process, it is difficult to accurately locate the femoral artery and successfully perform the puncture. Traditional femoral artery puncture mainly relies on the doctor's experience and touch, lacking effective real-time monitoring means, which easily leads to complications such as puncture failure, damage to surrounding tissues and blood vessels, increasing the patient's pain and treatment risk. At the same time, during the puncture process, it is difficult for the doctor to obtain the blood oxygen information of the puncture site in real time, and it is impossible to timely judge whether the puncture needle accurately enters the femoral artery, affecting the safety and success rate of the operation. For beginners, it is difficult to judge the position of the femoral artery and it is impossible to effectively practice the puncture.

[0016] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "inner", "outer", "vertical", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0017] In the present invention, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] The following further details a femoral artery puncture device of the present invention with reference to the drawings.

[0019] Combined with the attached Figures 1-4 , the present invention is introduced in detail.

[0020] A femoral artery puncture device includes a transmissive blood oxygen measurement device 1, a display 2, and a puncture needle 3. The display 2 is rotatably connected to the puncture needle 3 through an angle adjustment mechanism. This design enables the doctor to flexibly adjust the angle of the display 2 according to actual needs during the operation, so as to observe the puncture situation more clearly. The transmissive blood oxygen measurement device 1 is arranged at the rear end of the puncture needle 3 and is wirelessly signal-connected to the display 2, and can transmit the measured blood oxygen information to the display 2 in real time, facilitating the doctor to obtain it. The transmissive blood oxygen measurement device 1 includes an LED light-emitting tube 4 and a blood oxygen detector 5. The LED light-emitting tube 4 irradiates towards the blood oxygen detector 5, and the blood oxygen information of the puncture site is measured by detecting the change in the intensity of the light after passing through the tissue.

[0021] Further, the angle adjustment range of the angle adjustment structure is 25 - 35 degrees. Within this angle range, it can not only meet the doctor's requirements for the angle of the display 2 in different operating postures, but also ensure the stability and reliability of the connection between the display 2 and the puncture needle 3.

[0022] Further, several transmissive blood oxygen measurement devices 1 are provided and are circumferentially distributed at the rear end of the puncture needle 3. Multiple transmissive blood oxygen measurement devices 1 can measure the blood oxygen of the puncture site from different angles, obtain more comprehensive and accurate blood oxygen information, and improve the accuracy of judging the position of the puncture needle 3.

[0023] Further, the models of the puncture needle 3 include 5F, 6F, 8F, 10F. Multiple models of the puncture needle 3 can be applicable to different clinical needs and patient conditions, increasing the applicability and flexibility of the device.

[0024] The specific implementation process of a femoral artery puncture device of the present invention is as follows:

[0025] Example 1: Before performing a femoral artery puncture surgery, the doctor selects a puncture needle 3 of a suitable model according to the specific situation of the patient. For example, for a patient of normal build, a 6F model puncture needle 3 is selected. Connect the display 2 to the puncture needle 3 through the angle adjustment mechanism and adjust the angle to a suitable position, generally adjusted to 28 degrees first. Turn on the transmissive blood oxygen measurement device 1 and the display 2 to establish a wireless signal connection between the two. During the puncture process, the LED light-emitting tube 4 irradiates towards the blood oxygen detector 5. After the light passes through the tissue at the puncture site, the blood oxygen detector 5 detects the change in light intensity and converts the data into blood oxygen information and transmits it to the display 2 through a wireless signal. The doctor observes the blood oxygen data displayed on the display 2 in real time. When the blood oxygen data shows the arterial blood oxygen level, it indicates that the puncture needle 3 has accurately entered the femoral artery, and the puncture operation is completed.

[0026] Embodiment 2: For patients with a relatively large body size, it may be necessary to select a puncture needle 3 with a larger model, such as an 8F model. During the puncture operation, due to the physical structure characteristics of the patient, the doctor can adjust the angle of the angle adjustment mechanism to 32 degrees to observe the display 2 more clearly. The plurality of transmissive blood oxygen measurement devices 1 distributed in a circumferential manner obtain blood oxygen information of the puncture site from different angles, and the display 2 comprehensively displays this information. The doctor judges the position of the puncture needle 3 based on the more comprehensive and accurate blood oxygen data, thereby improving the success rate of the puncture.

[0027] The above describes the present invention and its embodiments. Such a description is not restrictive. What is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the present invention, design similar structural forms and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
