Description

A protection support device for hemodialysis puncture position

Technical Field

The invention relates to the technical field of medical instruments, in particular to a protective bracket device for a hemodialysis puncture part.

Background

Hemodialysis patients increase year by year, and patients who receive internal fistula operations are increasingly, wherein the internal fistula puncture needle used for three times per week and four hours each time is a 16G steel needle, the needle is hard and thick, and the skin at the internal fistula is repeatedly punctured, so that scar tissue is formed on the skin at the internal fistula puncture site for a long period of time, the bleeding or the slippage is easy, particularly, the blood swelling is caused by the fact that the needle head slides out of the blood tube due to the involuntary movement of limbs when the patients sleep well, or the blood dialysis treatment is stopped by sliding out of the body, and the life of the patients can be endangered if the patients are not found in time. The inquiry of documents about the currently used internal fistula protecting bracket is that 1996 authors develop a simple protecting bracket which is separated from a puncture part and a quilt and is used up to now. However, the internal fistula protective bracket has more defects, is not beneficial to observation of medical personnel, can not fix limbs well due to involuntary movement, and has more damage to bed sheets due to the use of the towel holding forceps. The involuntary movements of the limbs and the observation and damage to the bed unit by the medical staff are not well protected when the patient is asleep.

The internal fistula protecting bracket is only separated from the puncture part and the cover, so that the patient can not be well fixed by the involuntary movement of the limbs when sleeping, and once the needle head slips, the patient can be endangered by local hematoma or massive hemorrhage; moreover, medical staff can observe the condition of the internal fistula puncture of the patient only by opening the cover, and the damage to the bed sheet is increased by using the tissue holding forceps to fix the blood path tube every time, so that a large amount of financial resources, material resources and manpower are needed to be spent for a long time.

The Chinese patent application: CN204364527U discloses a protective bracket used in medical treatment, in particular to a hemodialysis internal fistula protective bracket. The protective bracket comprises at least two arched brackets which are arranged side by side at a certain interval, and a plurality of connecting brackets are arranged between the arched brackets; the width of the arch support is 15-20cm, and the height of the arch support is 12-18 cm. Although the device can avoid the patient to be covered by the tractive pjncture needle when moving out, prevents to cause the danger of heavy bleeding, but the device does not set up the device that can fix the pipeline, consequently the pipeline of not fixing in the concrete implementation can cause to hold the fixed damage to the sheet of towel forceps, and the bottom also does not have the device that can supply the patient to carry out the bracketing in addition, and the blood stain or the liquid that patient's wound exuded pollute the bedquilt easily, and then increase medical personnel's work burden.

The Chinese patent application: CN205885757U discloses an internal fistulization double-track support for an ulnar artery and basilic vein, which comprises a fixed frame and a fixed plate, wherein the fixed frame comprises two slide rails and two telescopic rods; the two slide rails are arranged in parallel opposite to each other up and down and are connected through a telescopic rod; the telescopic rods are perpendicular to the sliding rail, and the two telescopic rods are respectively arranged at the edge positions of the two ends of the sliding rail; the device can prevent that the oppression operation position is put down to the hand when patient sleeps, influences the success and the maturity of internal fistula, though stop the puncture position in the effect directly and the bed surface contact to avoid oppressing the puncture position, but the device is whole to be made for a simple metal frame, can cause uncomfortable sense for the patient using, all be the fretwork setting around the device moreover, hit the wound of patient internal fistula department very easily by some factors in the external world, cause the secondary injury to patient internal fistula department.

Therefore, in view of the above, there is a need for a protection support device suitable for a hemodialysis puncture site, which can stably fix an internal fistula side limb of a patient, avoid an external object from being in close contact with the puncture site of the patient, reduce damage to a bed sheet caused by a tissue holding forceps, and improve the comfort level of the patient, but no report is found about the novel protection support device for the hemodialysis puncture site.
