Description

Technical Field

[0001] The utility model belongs to the technical field of granulation equipment, and particularly relates to a blood vessel puncture device and a blood vessel puncture system positioned under ultrasound guidance. Background Art

[0002] In recent years, the use of ultrasound to guide vascular puncture and placement of vascular access devices (PICC) by clinical nurses has become increasingly popular. However, a large number of vascular puncture operations, such as rapid establishment of channels in emergency situations, blood collection, blood gas analysis, and placement of short venous catheters, still rely mainly on traditional methods of palpating the blood vessels. In order to improve the success rate of puncture, reduce patient pain, and increase patient satisfaction with nurses and hospitals, the demand for the use of ultrasound visualization technology to guide vascular puncture will also increase in the future.

[0003] At present, ultrasound-guided vascular puncture uses ultrasound scanning to determine the existence and location of the target blood vessel before puncturing the skin, and then performs immediate vascular puncture under ultrasound guidance. In this way, the operator still needs to grasp and adjust the insertion angle, swing, and depth of the puncture needle by himself, so that the "three degrees" can be perfectly combined to accurately complete the vascular puncture. Otherwise, the puncture needle is easy to go out of the scanning range during puncture or the needle "three degrees" must be adjusted repeatedly, thereby increasing the operation time and patient pain, and reducing patient satisfaction. Although one or two superconducting instruments now have positioning devices that can control the insertion angle and swing of the needle, they still have shortcomings and cannot meet the various and large clinical vascular puncture needs. One of them is: a set of The guide needle holder for longitudinal puncture on the probe requires complicated assembly. After puncture, the puncture needle cannot be easily and smoothly separated from the guide needle holder, and the guide needle holder needs to be removed. Moreover, it is not a disposable item and needs to be repeatedly disinfected, which cannot meet the aseptic operation principle of vascular puncture and a large number of vascular puncture work; the second type: a guide needle holder for transverse puncture installed on the probe. This guide needle holder is designed according to the depth of the blood vessel. Different corresponding needle guides must be selected for each blood vessel depth. Sometimes the blood vessel depth changes with the change of patient posture or the first puncture is unsuccessful and the blood vessel puncture needs to be replaced. When the depth of the blood vessel for the second puncture is different, the guide needle holder needs to be replaced again, which is also time-consuming and material-consuming. This puncture is mainly used for blood vessel puncture when placing PI CC vascular channel devices.

[0004] It can be seen that due to the complexity of the two ultrasound-guided positioning puncture operation methods, or the need for some supporting materials, a large number of clinical vascular punctures cannot be performed using ultrasound guidance. Utility Model Content

[0032] The following will be combined with the accompanying drawings to clearly and completely describe the technical solution in the utility model.

[0034] Embodiment 1:

[0035] like Figure 1-4 As shown, the first embodiment provides a device for positioning blood vessel puncture under ultrasound guidance, and the device for positioning blood vessel puncture under ultrasound guidance includes: an ultrasound probe 1 and a locator 2;

[0036] Among them, the ultrasonic probe 1 includes a mounting surface; the locator 2 includes a mounting position and a puncture groove 202 running through the body of the locator 2; and the locator 2 is detachably connected to the mounting surface through the mounting position, and the surface of the ultrasonic probe 1 is provided with a guide line 5 parallel to the detection trajectory.

[0037] Specifically, the utility model proposes an ultrasound-guided vascular puncture positioning device, which integrates an ultrasound probe 1 and a locator 2 including a puncture channel 202 into an integrated structure, so that the ultrasound probe 1 can be used to locate the position and depth of the blood vessel while performing vascular puncture, thereby providing accurate puncture basis for vascular puncture and greatly improving the efficiency of vascular puncture. Furthermore, the skin forms a puncture angle, which is a pre-designed fixed X° angle, which can ensure the puncture of blood vessels at a depth of 0.5-3.5cm under the skin, and can control the swing of the puncture needle so that the puncture needle will not deviate from the image plane area; the puncture needle can be inserted into the needle insertion puncture channel 202, and when the ultrasound probe 1 scans the longitudinal surface of the blood vessel, the puncture needle is pushed along the puncture channel 202 to puncture the blood vessel; the application software function on the ultrasound display screen realizes the simulated puncture image extended along the puncture channel 202, and evaluates the blood vessel conditions at the blood vessel puncture point before puncture (such as: whether there is a venous valve, blood vessel size, structure and adjacent relationship), and if there is a venous valve, the probe can be moved up and down to select the best puncture point for the blood vessel. Longitudinally positioning the blood vessel puncture can obtain the longest blood vessel length consistent with the probe scanning width, and can pre-evaluate the conditions at the blood vessel puncture point. A locator 2 can puncture all blood vessels within the depth range of 0.5-3.5cm. This method of positioning blood vessel puncture can meet the needs of placing vascular channel devices such as PI CC. The transverse positioning blood vessel puncture part is divided into: the application software realizes a positioning central axis reference line in the middle of the displayed transverse scanning ultrasound image, marks a "↓" (guide line 5) puncture line and needle insertion point in the middle of the scanning width on the front of the probe, moves the scanned blood vessel cross section (circular blood vessel) to the central axis reference line of the image plane, so that the blood vessel and the central axis form a "Φ" image, and the puncture needle is inserted from the probe "↓" needle insertion point, and the needle shaft of the puncture needle is kept parallel to the puncture line on the puncture point to puncture the blood vessel. This puncture method is convenient, simple, and fast, suitable for puncturing blood vessels with a depth of about 1 cm, and plays a rapid and positive role in placing short intravenous catheters, blood collection, and quickly establishing vascular channels during emergency treatment. This meets all clinical vascular punctures, enables ultrasound technology to be used more widely, and thus better serves patients.

In this way, the slide groove 301 and the slide rail 201 can be installed and displaced by the cooperation of the slide groove 301 and the slide rail 201.

[0039] In some possible embodiments, the ultrasound-guided positioning vascular puncture device also includes a plurality of sliding members 4, one side of the sliding member 4 is fixedly connected to the slide rail 201, and the other end of the slide rail 201 extends into the slide groove 301 and contacts the inner wall of the slide groove 301, thereby ensuring the stability of the slide rail 201 and the slide groove 301 during the sliding process.

[0040] Furthermore, the sliding member 4 has an arc surface, and the arc surface contacts the inner wall of the slide groove 301, and the friction between the sliding member 4 and the inner wall of the slide groove 301 is reduced by the arc surface;

[0041] In some possible implementations, the ultrasound probe 1 further includes a display screen for displaying ultrasound images.

[0042] In some possible implementations, the ultrasound probe 1 is provided with an adjustment button for adjusting and controlling the instructions of ultrasound detection.

[0043] In some possible implementations, the ultrasound probe 1 has a gripping portion for gripping.

[0044] Furthermore, the cross-section of the gripping portion is wavy, making it easier to bear force when gripping.

[0045] In some possible implementations, the grip portion has an outer layer of silicone.
