Problems solved by technology

[0004] However, the time required for puncture is usually longer. When the patient does not cooperate or the puncture fails due to other reasons and the puncture is re-punctured, the puncture time may even reach several hours. It is difficult for medical personnel to compress and fix patients, so a fixation device that can be used for venipuncture or arterial puncture is needed

Embodiment 1

[0041] A multi-point fixation device suitable for PICC catheterization and arterial puncture catheterization, such as figure 1 with figure 2As shown, it includes a main body 1 and a fixed block 3. The rear side wall of the main body 1 is attached to the patient's back, and the cross section of the rear side wall of the main body 1 is arc-shaped, which can better fit the patient's back; the main body 1 Two first laces are fixed on the rear side wall of the main body 1 through pin shafts, and the two first laces are respectively located at the left and right ends of the main body 1. In actual implementation, the ends of the two first laces away from the main body 1 are fixed by needle and thread There is Velcro, the two first straps are connected by Velcro. Two arc-shaped plates 12 are welded on the top of the main body 1, and the vertical projections of the two arc-shaped plates 12 are respectively located at the left and right ends of the main body 1, and the longitudinal se...

Embodiment 2

[0052] On the basis of Example 1, such as Figure 4 As shown, the left end of the first rod body 2 in this embodiment is welded with the installation block 14 , and the connection position between the first rod body 2 and the installation block 14 is located at the lower end of the installation block 14 . The mounting block 14 is vertically provided with a second passage, and the lower end of the rotating shaft 4 passes through the mounting block 14; the upper end of the mounting block 14 is provided with a first passage, such as Figure 5 As shown, after the mounting block 14 is rotated by 90°, the bottom of the rotating shaft 4 passes through the first channel to position the mounting block 14, and at this time, a limiting space is formed between the first rod body 2 and the first channel.

[0053] The right side of mounting block 14 is provided with U-shaped block 6, combines Image 6 As shown, the end of the U-shaped block 6 is integrally formed with a block 61, and the w...

Embodiment 3

[0056] On the basis of embodiment 1 or embodiment 2, such as Figure 7 As shown, the main body 1 in this embodiment includes a left half body and a right half body. The right wall of the left half body and the left wall of the right half body are integrally formed with a plurality of sawtooth blocks, and the vertical gaps of the plurality of sawtooth blocks are distributed. , and the sawtooth blocks on the left half and the right half mesh with each other, the shaft 4 passes through the aligned sawtooth blocks vertically and is screwed with the bottom sawtooth block, and the left half and the right half are connected through the shaft 4 . In actual implementation, multiple rotating shafts 4 are provided to improve the fixing effect on the sawtooth portion.

[0057] Such as Figure 8 As shown, the thickness of the sawtooth part on the left half body gradually decreases from left to right, and the thickness of the sawtooth part on the right half body gradually increases from l...

Abstract

The invention relates to the field of medical assistance, and particularly discloses a multi-point fixing device suitable for PICC catheterization and arteriopuncture catheterization. The multi-point fixing device comprises a main body and a fixing block, wherein arc-shaped plates are fixed to the top of the main body, first tying belts are fixed to the two ends of the main body, and two third tying belts are fixed to the tops of the two arc-shaped plates; a supporting rod is hinged to the side wall of the main body; a supporting groove with an opening facing the main body is formed in the fixing block, the supporting groove and the fixing block are horizontal, the end, away from the main body, of the supporting rod transversely extends into the supporting groove, and the supporting rod is slidably connected with the supporting groove; and an arc-shaped through groove with an upward opening is formed in the top of the fixing block, and a plurality of second tying belts are sequentially distributed in the length direction at intervals. The multi-point fixing device suitable for venipuncture and arteriopuncture can support and fix the arm of a patient, so the fixing difficulty of medical staff is reduced, and meanwhile, puncture failure caused by the fact that the patient does not cooperate is avoided.

Description

technical field [0001] The invention relates to the field of medical assistance, in particular to a multi-point fixing device suitable for PICC catheterization and arterial puncture catheterization. Background technique [0002] When a patient needs to perform PICC catheterization or arterial puncture catheterization, in order to facilitate the puncture and improve the success rate of catheterization, it is usually necessary to make the patient's arm and the longitudinal axis of the body form a 90° angle with the palm facing upward. In addition, during the puncture, the medical personnel cannot directly observe the position of the puncture needle, but need to observe through the ultrasonic probe. Therefore, the medical personnel performing the puncture need to hold the ultrasonic probe in one hand and the puncture needle in the other hand, which makes it difficult to position the patient and makes the patient Maintain a fixed posture. [0003] Since the puncture needle is u...
