Description

  The present invention relates to a fixture for an infusion blood vessel or a puncture needle used at home hemodialysis.

  When performing hemodialysis in hospitals and other facilities, nurses, technicians, and other medical professionals prepare the dialysis machine, connect the needle, connect the dialyzer to the blood circuit (intravascular), and remove the needle. ing. Also, if any trouble occurs before or after dialysis or during dialysis, other caregivers in the facility can help.

  On the other hand, when a patient performs hemodialysis at home, the patient's family or helper is the assistant. In that case, there is usually one helper, so when you need to puncture, connect the dialyzer to the blood circuit, and remove the needle, both the helper's hand and the patient's hand (the one that will not pierce the needle) Thus, each operation is performed.

  In this case, when the apparatus is operating smoothly and each operation can be accurately processed as scheduled, the operation can be performed with the helper's both hands and the patient's one hand. However, when some trouble occurs, there is a problem that it is difficult for either the caregiver or the patient to deal with the trouble.

  In particular, if you have a blood circuit connection part in your hand that needs to be kept clean, the connection part will be contaminated if you take your hand off. It was almost impossible to respond.

  In addition, conventional dialysis machines are equipped with various circuit holders. These are used to organize the dialysis machine circuit and hold the circuit in place, and serve as a support for patients and caregivers. There was no mobile thing that could fulfill the requirements.

Furthermore, a drainage tube fixture for fixing the tube and the bucket when the drainage in the blood circuit is transferred to the bucket after completion of dialysis is disclosed (for example, Patent Document 1). However, such a fixture is an instrument for attaching the drainage tube to the bucket by a suction cup and transferring the waste liquid from the tube into the bucket, and cannot be applied to other than the bucket. Since the drainage tube fixed here is discarded after use, there is no problem even if it is slightly deformed or damaged when sandwiched by the fixture, and the drainage tube once fixed Is not envisaged for subsequent use in dialysis.
