Description

PICC puts that tub patient changes dressings and leans on comfortable seat

Technical Field

The invention relates to the technical field of medical instruments, in particular to a comfortable seat for dressing change of a PICC catheterized patient.

Background

The PICC is called as a central venous catheter implanted in a peripheral vein, and is used for central venous catheterization through peripheral venipuncture, the catheter is used for puncturing veins of a peripheral arm, the catheter directly reaches a large vein close to the heart, so that chemotherapy drugs are prevented from being in direct contact with the veins of the arm, and the blood flow speed of the large vein is high, so that the chemotherapy drugs can be quickly diluted, and the stimulation of the drugs to blood vessels is prevented. Therefore, the upper limb vein can be effectively protected, the occurrence of phlebitis is reduced, the pain of the patient is relieved, and the life quality of the patient is improved.

When a patient needs to change the medicine, medical staff firstly need to disinfect hands, then open a PICC medicine changing package, take out a treatment towel in an aseptic mode, fill up the treatment towel below the side limb of the patient, then assist the patient in lying in a flat position and need to stretch out the arms, measure the arm circumference ten centimeters above the elbow transverse striation by using a tape, then disinfect the hands, remove skin and catheter glue marks by using seventy-five percent alcohol cotton swabs, disinfect the hands, wear cleaning gloves, tear the outer package of the alcohol cotton swabs to be mouth-shaped, remove an old connector by using one hand above the connector of the hand-held catheter, remove the puncture catheter cross section and the outer wall by using the alcohol cotton swab to disinfect the catheter, wipe for fifteen seconds in all directions to be dried, connect a new connector and a catheter flusher, draw blood back to the infusion connector or an injector, then flush the catheter is flushed by using a positive pressure to seal the puncture catheter, adjust the puncture point by using a light pressure point, draw the transparent dressing along the zero point of the thumb to fix the left hand and fix the catheter, pull the transparent dressing in parallel to the middle point, and fix the catheter by using three percent alcohol cotton swabs, and place the sterile dressing, and press the transparent catheter for a transparent dressing for a fifteen percent sterile catheter, and fix the middle dressing by using ethanol, and pull the iodine dressing, and pull the middle dressing, and pull the iodine dressing, and pull the dressing for removing the dressing for fixing catheter from the dressing for two times, and pull the dressing for three times, and pull the dressing for fixing the dressing for three times, the PICC dressing changing device is characterized in that after placement, shaping is carried out firstly, then the whole transparent dressing is pressed, the paper frame is removed while the whole transparent dressing is pressed, the butterfly-shaped cross of the first fixing adhesive tape is arranged on the lower edge of the fixing device, and the dressing changing of the PICC can be completed after the second adhesive tape is fixed above the butterfly-shaped cross.

Whole operation is comparatively loaded down with trivial details, consequently generally when changing dressings to PICC patient, generally be that medical personnel change dressings to patient's sick bed position, but along with PICC patient's increase, some PICC patient has been discharged from the hospital, generally go to outpatient service PICC room when these patients change dressings and change dressings, patient all sits when changing dressings and changes dressings, do not have special support frame, patient mostly is just the arm, then slightly lifts up, make things convenient for the nurse to disinfect, it is of a specified duration to lift up, patient can produce uncomfortable sense, thereby make the arm take place to rock, increase the difficulty of changing dressings.

The Chinese patent with the patent number of CN113768737A discloses a PICC dedicated seat for drug exchange, which belongs to the technical field of medical instruments and comprises a seat body, wherein two support plates are symmetrically arranged on handrails of the seat body, a placing groove is formed in each support plate, a rotating block is arranged on the inner wall of each placing groove through a rotating shaft, a support mechanism is arranged at the top end of each rotating block, a telescopic door is arranged at an opening of each placing groove, two lock catches are arranged on each telescopic door, and a lock hole matched with each lock catch is further formed in each support plate; the arm extension device is simple in structure, the arms of a patient can be supported through the supporting mechanism arranged on the seat, the arm of the patient is prevented from shaking, a nurse can change the medicine conveniently, the supporting mechanism can be adjusted properly according to the body type of the patient, the applicability of the device is improved, the arm extension device can be extended through the extension mechanism, the supporting range of the patient is enlarged, the comfort of the patient is improved, and meanwhile, the supporting mechanism and the extension mechanism can be stored when not used, do not occupy space and are convenient to use.

But still there is certain not enough when actually changing dressings, for example the handrail angle of chair of changing dressings can not be adjusted, when changing dressings, patient can only take the arm on the handrail, and the angle value undersize between arm and the health, can't make patient's arm abduction, it is located the one side that is close to patient's health to change dressings the kneck, when changing dressings, lead to medical personnel to change dressings inconveniently on the one hand, on the other hand patient need cooperate medical personnel's the operation of changing dressings, outwards expand the department of changing dressings on the arm, great reduction patient's travelling comfort when changing dressings.
