Automatic liquid stopping type intravenous infusion unit

Abstract

The invention discloses an automatic liquid-stopping intravenous infusion device, which comprises a cork puncturer, an infusion hose, a drip pot, a flow regulator, and an intravenous infusion needle. The drip pot is composed of an upper drip pot and a lower drip pot, and the lower drip pot has a cover Connected to the lower end of the upper dripping pot; the cavity of the upper dripping pot is in the shape of an inverted cone; the upper end of the upper dripping pot is provided with a liquid inlet, and a floating body is arranged in the cavity of the upper dripping pot, and the floating body is a spherical structure; between the upper dripping pot and the lower There is a spherical structure with an upward opening between the dripping pots. The diameter of the spherical structure is equal to the length of the narrow opening at the lower end of the cavity. There is a liquid outlet at the bottom of the spherical structure; The upper end is provided with an air filter tube, and the outer end of the air filter tube is provided with a switch. The structure of this design is simple, which not only greatly improves the reliability of stopping the liquid, but also can manually control the liquid medicine placed in the infusion set to continue to be injected into the human body, which can effectively guarantee the therapeutic effect, help to enhance the trust of patients in nurses, and promote the development of nurses and nurses. harmonious.

Description

technical field [0001] The invention relates to an intravenous transfusion device, in particular to an automatic liquid-stopping intravenous transfusion device. Background technique [0002] Traditional intravenous infusion sets are generally composed of intravenous infusion needles, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, cork puncturers, and air filters for intake pipes. If it is not timely, the medicine liquid will easily lead to blood backflow or even air input into the human body, which will affect the patient's health; at the same time, it will also increase the intensity of the nursing work of the medical staff, which will easily lead to doctor-patient disputes. With the continuous development of infusion technology and the increasing clinical requirements, people expect a better product that is safer and more effective. The automatic stop liquid infusion set is a new type of intravenous infusion set that replaces the traditional infu...

Problems solved by technology

However, this design has the following disadvantages: the first is that when the float is located at the lower end of the drip pot and cuts off the liquid outlet path of the drip pot, the liquid will stop automatically at this time, and the liquid medicine of tens of milliliters blocked in the infusion set below the float cannot continue to be injected into the human body. , resulting in a waste of liquid medicine

The second is to use the lower end of the float to block the liquid outlet of the drip pot. The lower end of the float must be precisely connected to the liquid outlet of the drip pot. The extrusion of the intravenous infusion set during transportation and other links will easily deform the drip pot and the float, resulting in low sealing reliability. , low security

The disadvantage of this design is that it is difficult for patients to perceive and understand this design, which leads to unnecessary tension for patients.
