Description

Upper limb fixing device for picc catheterization

Technical Field

The utility model relates to the technical field of medical equipment, in particular to an upper limb fixing device for picc catheter.

Background

PICC (peripheral Inserted Central cstter) refers to a catheter placed into the Central vein via a peripheral vein such as the elbow. The technology provides a safe and effective venous transfusion path for tumors, parenteral nutrition, premature infants, old patients and the like, and the problem of invisible vascular puncture is solved by placing a tube under the guidance of ultrasonic. The PICC is characterized in that a catheter is used for puncturing from a vein of a peripheral arm, the catheter directly reaches a great vein close to the heart, so that the direct contact between chemotherapy drugs and the arm vein is avoided, and the blood flow speed of the great vein is high, so that the chemotherapy drugs can be quickly diluted, and the stimulation of the drugs to blood vessels is prevented and treated, so that the upper limb vein can be effectively protected, the occurrence of phlebitis is reduced, the pain of a patient is relieved, the life quality of the patient is improved, and the PICC is widely applied to clinic at present.

Currently, PICC (peripherally inserted central catheter) catheterization beds used in hospitals are common hospital beds; during operation, the patient takes the supine position, the body moves to the bedside of the other side as much as possible, and the puncture arm extends to the right side of the body and the bedside of the hospital bed as much as possible, so that the venipuncture area is exposed as much as possible.

The above-mentioned current PICC puts a tub operation and has the following problem:

firstly, when the PICC is placed, one or two nurses are additionally required to be equipped besides a tube placing person, the PICC is painful to place, and particularly when repeated puncture is required due to puncture failure, the PICC needs to assist the person to press the limb of the patient hard to ensure normal operation of the tube placing operation, so that the actual working intensity of medical personnel is inevitably increased;

secondly, as the existing PICC puncture does not have a standardized arm supporting structure, the tube placing personnel needs to temporarily search for an arm supporting part such as a pillow and the like during each puncture, so that the tube placing time of each patient is indirectly prolonged, and the tube placing efficiency is low;

thirdly, because PICC puts the pipe process and requires high to patient's posture, need to ensure that patient's arm straightens for a long time, lead to patient's arm can be because of keeping same action for a long time and the condition such as numbness and fatigue shake appears, patient's comfort level is poor when not only putting the pipe, patient probably shakes and appears the arm of independence and move down the action because of arm numbness even when the operation, and then leads to the puncture position to be higher than normal, causes the puncture failure, has brought very big puzzlement for actual puncture work.

SUMMERY OF THE UTILITY MODEL

Detailed Description

Referring to the attached drawings, an upper limb fixing device for a picc placing tube comprises a base 1, wherein a first limiting component 2 and a second limiting component 3 are connected to the base 1 in a sliding manner; the second limiting component 3 has the same structure as the first limiting component 2;

the lower end of the base 1 is provided with an L-shaped fixing plate 10, the L-shaped fixing plate 10 is connected with a clamping bolt 11, the upper surface of the base 1 is provided with a T-shaped slideway 12, and the side wall of the base 1 is provided with a plurality of groups of limiting holes 13;

the first limiting component 2 comprises a sliding plate 20, the sliding plate 20 is connected with a T-shaped slide rail 12 through a sliding rail 21 arranged at the lower end of the sliding plate 20, a sleeve 200 is arranged on the left side of the upper end of the sliding plate 20, a sliding rod 201 is connected in the sleeve 200 in a limiting sliding mode, a first spring 202 is installed between the lower end of the sliding rod 201 and the sleeve 200, the upper end of the sliding rod 201 is connected with the left end of an upper clamping plate 22 through a rotating shaft 203 in a rotating mode, an adjusting rod 27 is fixedly connected to the right end of the lower side of the upper clamping plate 22, a plurality of protrusions 270 are vertically distributed on the adjusting rod 27, a spongy cushion 23 is arranged at the lower end of the upper clamping plate 22, an adjusting cylinder 24 is connected to the right side of the upper end of the sliding plate 20, a plug pin 25 is inserted in the jack, a second spring 26 is installed between the tail end of the plug pin 25 and the outer wall of the adjusting cylinder 24, a lower supporting plate 28 is arranged between the upper end of the sliding plate 20 and the sleeve 200 and the adjusting cylinder 24, the spongy cushion 23 is arranged at the upper end of the lower supporting plate 28, a plurality of fixing holes are formed in the right side of the sliding plate 20, a plurality of fixing holes are formed in the sliding plate, and a plurality of the fixing holes are formed in the limiting bolt 29, and the limiting bolt extends into the fixing hole 13.

The working principle is as follows:

when in use, a medical worker places the base 1 at one side of a sickbed, and fixes the base 1 on a bedstead of the sickbed through the L-shaped fixing plate 10 in cooperation with the clamping bolt 11;

medical personnel adjust the relative distance between the first spacing subassembly 2 of arm length adjustment and the second spacing subassembly 3 according to the patient, and the concrete adjustment is: keeping the second limiting component 3 still, rotating the limiting bolt 29 of the first limiting component 2 to enable the limiting bolt 29 of the first limiting component 2 to be screwed out of the fixed hole, pushing the sliding plate 20 of the first limiting component 2, enabling the sliding plate 20 of the first limiting component 2 to slide in the T-shaped slideway 12 through the sliding rail 21 of the first limiting component 2, rotating the limiting bolt 29 of the first limiting component 2 into the adjusted fixed hole after being adjusted to a proper position, and at the moment, enabling the first limiting component 2 not to move relative to the base 1;

the first limiting component 2 is used for limiting the wrist part of the patient, and the second limiting component 3 is used for limiting the upper arm of the patient;

because the first limiting component 2 and the second limiting component 3 have the same structure and the same using process, the specific using process is only exemplified by the first limiting component 2, and the second limiting component 3 can be used by referring to the first limiting component 2;
