Description
Technical Field
The invention relates to the technical field of infusion devices, in particular to a portable infusion flow adjusting assembly.
Background
The traditional medical transfusion device consists of a liquid medicine bottle, a needle head, a transfusion tube, a Murphy's dropper, a transfusion tube clamp, a flow regulator and a vein retention needle; during infusion, medical personnel hang the liquid medicine bottle on the support, keep certain difference in height between liquid medicine bottle and the patient, liquid in the liquid medicine bottle gets into patient's vein under the action of gravity, though this kind of infusion mode is simple, but, occupation space is great, only can infuse for patient under static state, lacks the flexibility.
Application No. 2021107754211 discloses a medical portable hanger-free self-priming infusion device, which can adjust the length of an infusion tube according to actual conditions by mounting a take-up box on the infusion tube so as to adapt to the condition that a special patient can carry out infusion simultaneously when going to a toilet or a person for going out, and avoid the condition that the infusion tube is too long and is easy to tear off and easily twine around the body after being fallen down; through set up the peristaltic pump on the transfer line and receive the line box to all install the peristaltic pump and receive the line box in the shell, the shell can be fixed at patient's waist, has changed current adoption completely and has hung the mode of carrying out the infusion, need not to consider infusion bag's height, has avoided the condition of blood refluence, can adapt to the condition and the emergency rescue condition of special patient's activity of going out.
The infusion device which supplies power to the human body by the gravity is often limited by environmental places, is inconvenient to carry and has large application limitation. For example, in some sudden sanitary emergencies such as car accidents, natural disasters, war and the like, the injured place of the sick and wounded is in the field far away from a large-city hospital, and the sick and wounded are usually transported to the hospital by vehicles after on-site treatment, but the traditional infusion device is difficult to smoothly carry out infusion by a short transport tool (such as the transport tool vibrates, the infusion bag supporting tool is easy to topple over due to swinging, the infusion bag falls off and the like); when some infusion devices adopting the peristaltic pumps input different types of liquid medicines, the medical staff for load transfer needs to pay attention to whether the liquid is completely infused or not, so that the peristaltic pumps are prevented from idling, other liquid needs to be replaced, and the rescue of the patient is influenced. There is therefore a need for an infusion device that is more suitable for infusing a patient in an emergency situation as described above.
