Description

Technical Field

[0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional radial artery puncture auxiliary device. Background Art

[0002] Arterial puncture is widely used in various treatments, examinations and tests. It is an indispensable clinical operation. The radial artery has a thinner diameter and is one of the most spasmodic muscular blood vessels in the human body. Therefore, radial artery puncture is very likely to fail due to failure to puncture the blood vessel and repeated stimulation causing arterial spasm. Before puncture, find out the course of the radial artery and choose a location where the radial artery has a strong and straight pulse. Generally, the closer to the wrist crease, the stronger the radial artery pulse and the easier it is to touch. However, the radial artery here is sometimes tortuous and has many small branches, making it more difficult to puncture. Conventional means use the index finger to touch, while moving up and down to feel the most obvious pulse position, move toward the proximal end to determine the puncture direction, and then insert the needle just above the artery.

[0003] For example, a radial artery puncture assistant disclosed in the invention with the authorization announcement number CN109907803B includes a support plate; a rack guide plate is provided on the support plate at one side of the bracket, and a guide block is sleeved on the rack guide plate, and a ratchet part and a pawl part are arranged inside the guide block; a cantilever plate is horizontally extended on the guide block plate surface, and a pressure plate is arranged at the cantilever end of the cantilever plate; when the patient's wrist is placed on the bracket, the pressure plate is located directly above the radial artery of the patient's wrist; two groups of through holes are sequentially arranged on the pressure plate along the length direction of the bracket groove, and the two groups of through holes respectively constitute inspection holes for the operator's index finger and middle finger to press in order to detect the pulse of the radial artery, and the area between the two groups of through holes is arranged with a needle hole for the puncture needle to pass through. The assistant can quickly and efficiently achieve the purpose of puncturing the patient's radial artery, and has the advantages of high convenience of operation and one-handed operation, which is conducive to clinical use.

[0004] However, the above scheme has the following problems: since the limb circumference of each patient is different during the limb bearing process, it is impossible to automatically adjust the support area according to the patient's limb circumference, which is inconvenient for patients to use. At the same time, since the height and angle of the patient's limb cannot be adjusted during radial artery puncture, the radial artery cannot be fully displayed, affecting the accuracy of puncture. For this reason, we propose a multifunctional radial artery puncture auxiliary device. Summary of the invention

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Embodiment 1

[0032] See also Figure 1-Figure 3The present invention provides a technical solution: a multifunctional radial artery puncture auxiliary device, comprising a limb support pad 3 and a bearing plate 2, the limb support pad 3 is arranged on the bearing plate 2, and an auxiliary bearing mechanism 1 is automatically unfolded symmetrically on both sides of the limb support pad 3;

[0033] The auxiliary supporting mechanism 1 includes a bidirectional ball screw 102, which is rotatably arranged in the groove body 101, and the bidirectional ball screw 102 is connected to the driving shaft of the first motor 107 located on the supporting plate 2. The groove body 101 is arranged on the supporting plate 2, and the arc-shaped support pad 103 is symmetrically and movably arranged on both sides of the limb support pad 3. An auxiliary support seat 106 is arranged at one end of the arc-shaped support pad 103, and an auxiliary pad body 104 is arranged on the auxiliary support seat 106. A pressure sensor 105 is arranged in the auxiliary pad body 104. Specifically, the pressure sensor 105 is connected to the built-in controller, the built-in controller is connected to the first motor 107, and the arc-shaped support pad 103 is connected to the bidirectional ball screw 102 through a guide assembly.

[0034] The guide assembly includes an arc-shaped slider 108, which is arranged at the bottom of the arc-shaped support pad 103. The arc-shaped slider 108 is slidably arranged in an arc-shaped guide groove 110, and the arc-shaped guide groove 110 is arranged on an arc-shaped bracket 109. The arc-shaped bracket 109 is arranged on one side of the limb support pad 3. By moving the arc-shaped slider 108 in the arc-shaped guide groove 110, the arc-shaped support pad 103 can be moved along an arc angle.

[0035] A longitudinal adjustment rod 112 is also provided on the arc-shaped slider 108. The longitudinal adjustment rod 112 is movably arranged in an adjustment port 111. The adjustment port 111 is arranged at the bottom of the arc-shaped guide groove 110. The longitudinal adjustment rod 112 is movably arranged in a guide sleeve 113. During the movement of the arc-shaped slider 108, the longitudinal adjustment rod 112 can move in the guide sleeve 113, so that the arc-shaped slider 108 can move smoothly along the arc-shaped slide groove. The guide sleeve 113 is arranged on a transverse nut 114. The transverse nut 114 is arranged on one side of the bidirectional ball screw 102. The guide sleeve 113 can be driven to move by moving the transverse nut 114, and the arc-shaped slider 108 can be driven to move by the longitudinal adjustment rod 112.

[0036] During use, when the patient's limbs are placed on the arc support pad 103, if the pressure sensor 105 does not detect pressure information, it means that the arc support pad 103 can fully support the patient's limbs. If the pressure sensor 105 detects pressure information on the auxiliary pad body 104, it means that the circumference of the limb exceeds the width of the arc support pad 103. At this time, the built-in control controls the first motor 107 to operate, and the first motor 107 drives the bidirectional ball screw 102 to rotate. The two sets of transverse nuts 114 move in opposite directions at the same time. The opposite movements of the transverse nuts 114 respectively drive the guide sleeves 113 to move, and the guide sleeves 113 drive the arc slider 108 along the arc through the longitudinal adjustment rod 112. The arc slide groove moves, and the arc slider 108 can make the longitudinal adjustment rod 112 move longitudinally in the guide sleeve 113 during the movement. The movement of the arc slider 108 drives the arc support pad 103 to move, and the movement of the arc support pad 103 drives the auxiliary support seat 106 to move, and the movement of the auxiliary support seat 106 drives the auxiliary pad body 104 to move. When the pressure sensor 105 in the auxiliary pad body 104 cannot detect the pressure, the first motor 107 stops running, and the synchronous arc trajectory of the two groups of arc support pads 103 is unfolded, which can automatically adjust the load-bearing range to meet the use of limbs of different circumferences. At the same time, the arc trajectory is unfolded to position the limbs and improve the stability of the limbs when they are placed.

[0037] Furthermore, a linear slider 115 is also provided on the transverse nut 114. The linear slider 115 is slidably provided in a linear slide groove 116. The linear slide groove 116 is provided at the bottom of the groove body 101. When the transverse nut 114 moves, it can drive the linear slider 115 to move in the linear slide groove 116, thereby improving the guiding performance of the transverse nut 114 when moving.

[0038] Furthermore, a limit slider is also provided on the longitudinal adjustment rod 112, and the limit slider is slidably set in the limit slide groove, and the limit slide groove is set on the inner wall of the guide sleeve 113. When the longitudinal adjustment rod 112 moves, it drives the limit slider to move in the limit slide groove, so that the moving position of the longitudinal adjustment rod 112 can be positioned.
