Description

Blood vessel access fixing device for hemodialysis

Technical Field

The invention relates to the technical field of fixing devices, in particular to a blood vessel access fixing device for hemodialysis.

Background

Hemodialysis is one of effective treatment measures for patients with chronic renal failure, and patients with renal insufficiency, particularly renal failure, are subjected to hemodialysis treatment for two to three times every week, wherein each dialysis treatment lasts for about 4 hours. Before hemodialysis is carried out on a patient, a vascular access needs to be established on the forearm of the patient, namely arteriovenous internal fistula, which is called a life line of the hemodialysis patient, and important protection is needed to prevent the blockage of the arteriovenous internal fistula. The problem that often appears in clinical at present has patient's tolerance and compliance poor, if can rock the arm when consciousness, sleep or dysphoria, the relative displacement of arm blood guide needle pipe can make vein pjncture needle point adherence wall or produce and take off the needle, puncture phenomenons such as blood vessel to cause venous pressure to increase, hemodialysis can not normally go on, easily make artery end blood flow not enough moreover, lead to dialysis effect poor, the oozing blood is serious etc. and probably bring very big misery and fear for critical patient, and increased medical personnel's work load. At present, the vascular access is mainly built at the wrist and the elbow, and the hemodialysis upper limb fixing device in the prior art can only fix the wrist and lacks a fixed hemodialysis device which can fix and flexibly adjust the elbow.

Disclosure of Invention

The purpose of the present invention is to provide a blood vessel access fixing device for hemodialysis.

In order to achieve the purpose, the technical solution of the invention is as follows: a blood vessel access fixing device for hemodialysis comprises a base plate, a square base tube, an arm protection pad, a strip, a shaft sleeve hole, a bearing belt, a bearing tube, an extension tube, a first knob, a circular base tube, a shaft sleeve, an adjusting frame, a second knob and a telescopic rod.

The base plate is provided with a protective arm pad, two sides of the base plate are respectively provided with a square base tube, the left part of the square base tube is provided with a strip at the position of the base plate, the middle part of the square base tube is provided with a shaft sleeve hole, the right end of the square base tube is provided with a second knob, one end of a telescopic rod is arranged in the square base tube from a right end opening, front and back hacks of the adjusting frame penetrate through the shaft sleeve hole and the shaft sleeve pipe arranged at the right end of the telescopic rod, two inclined longitudinal hacks of the adjusting frame are both provided with a circular base tube, the circular base tube is arranged on two inclined longitudinal hacks of the adjusting frame, the front and back hacks of the telescopic tube penetrate through the shaft sleeve hole and the shaft sleeve pipe arranged in the base plate, the inclined longitudinal hacks of the telescopic tube are arranged in the circular base tube, one end of the square bearing bracket penetrates through the hacks, the front and back, a bearing belt is arranged between the two oblique longitudinal frame rods.

The working principle of the invention is as follows: when in use, the blood vessel access fixing device for hemodialysis is fixedly arranged at the front lower position of the upper limb of a patient, the length of the telescopic rod extending out of the square base tube and the length of the telescopic tube extending out of the round base tube are adjusted according to requirements, the gradient of the supporting bracket and the vertical height of the supporting tube are further adjusted, the telescopic rod is fixedly locked by the second knob, the telescopic tube is fixedly locked by the first knob, so that the upper limb and the joint of the patient are in the required comfortable position or functional position, the upper arm is bound and fixed on the arm guard pad of the base plate by the strip, the front wall is bound and fixed on the supporting belt of the supporting bracket by the strip, after the hemodialysis treatment is finished, the first knob is loosened to maximally retract the telescopic tube into the round base tube, the second knob is loosened to maximally adjust the length of the telescopic rod extending out of the square base tube, so that the supporting bracket is flatly arranged on the square base tube, and the first knob and the second knob are screwed, so that the size of the device is reduced, and the device is convenient to carry and store.

The beneficial effects of the invention are: the invention adopts the structural mode of combining the split parts, is suitable for fixing the upper arm and the forearm when the blood vessel access is built at the elbow part of the hand, can fix the elbow part of the hand in a natural bending state according to the requirement of a patient, reduces the working difficulty of medical personnel, and has the advantages of convenient operation, time and labor conservation, small volume, convenient carrying, firm fixation of the blood access and high working efficiency.
