Detailed Description

The following description is only intended to disclose the invention so as to enable any person skilled in the art to practice the invention. The embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art. The principles of the invention, as defined in the following description, may be applied to other embodiments, variations, modifications, equivalents, and other arrangements without departing from the spirit and scope of the invention.

As shown in fig. 1-3, the present invention provides a blood flow detector for automatically searching the detection position on the limb of the patient and detecting the blood flow. The blood flow detector comprises a base plate 10, a mechanical arm 20, a probe 30 and a control device 40.

The base plate 10 is used to mount the robotic arm 20 and to immobilize a patient's limb. In use, the base plate 10 contacts a support surface and the limb of the patient is secured to the base plate 10.

The robot arm 20 is mounted to the base plate 10. The robot arm 20 is a multi-joint robot arm, and can freely move in space, and can freely move in the horizontal and vertical directions, and can also perform movement operations such as rotation that change directions. The robot arm 20 has a pressure sensor built therein.

The probe 30 is mounted to the distal end of the robot arm 20 and moves in accordance with the movement of the robot arm 20. In use, the probe 30 contacts the skin of a patient's limb and is used to find an optimal blood flow detection location.

The mechanical arm 20 and the probe 30 are both connected with the control device 40, and the control device 40 controls the mechanical arm 20 to move so as to drive the probe 30 to search for a detection point of the limb of the patient positioned on the base plate 10.

The control device 40 comprises a detection host 41 and a computer 42, wherein the mechanical arm 20 and the probe 30 are electrically connected with the detection host 41, and the detection host 41 is connected with the computer 42. The detection host 41 is provided with an automatic position finding module and has a display screen. The position auto-search module of the detection host 41 is used to control the probe 30 to perform position modification positioning in case of the patient limb shaking.

When the blood flow detecting instrument works, firstly, limbs of a patient are fixed on a bottom plate 10, the skin surface of the patient to be detected faces upwards, under the control action of software built in a control device 40, a mechanical arm 20 drives a probe 30 to move freely in space, a built-in pressure sensor can enable the mechanical arm to be placed on the skin surface with uniform pressure, so that the probe 30 contacts the skin surface of the limbs of the patient and conducts transverse and longitudinal rapid scanning, the position with the strongest feedback signal of the probe 30 is marked, then the probe 30 reduces the range and detects in the position of the range, the orientation of the probe and the orientation of the skin are changed in the horizontal direction and the vertical direction at the same time, the optimal signal direction is marked, the optimal blood flow detecting point is determined through sampling detection in a short time, and finally the optimal blood flow. The detection process and the detection position can be directly displayed by the computer 42 or the display screen of the detection host 41 for the operator to view. The software of the control device 40 then automatically decides to perform further operations that follow.

When the patient limb shakes, the position automatic searching module in the detection host 41 corrects the detection position of the positioning probe 30 within a preset range. That is, the position auto-search module of the detection host 41 can quickly perform correction within a predetermined range to relocate to an optimal detection position.

Adopt the utility model provides a blood flow detection instrument can realize full-automatic searching detection position, liberates medical personnel's both hands, and medical personnel need not contact the patient and only need carry on simple affirmation measurement operation can. And the blood flow detector has the function of automatically correcting the position, and can effectively prevent the inconvenience of finding the detection position caused by the accidental shaking of the limbs of the patient. The blood flow detector has the advantages of high detection speed and high precision, and reduces the operation and use difficulty and the training cost.
