Problems solved by technology

At present, in clinical practice, the monitoring of inhaled anesthetics during anesthesia mainly focuses on the changes in the patient's physical signs, and because there are existing calculation methods for the dosage of various anesthetics, few people monitor patients during anesthesia. Research on the absorption of inhalation anesthetics and the discharge after anesthesia is over

Embodiment 1

[0024] Such as figure 1 As shown, the quantitative measurement system for the intake of anesthetic agents based on inhalation anesthesia in this embodiment includes: a two-way breathing mask 100, an anesthesia machine 200, an oxygen supply device 300, an air supply branch 400, an exhaust branch 500, an exhaust gas Recovery facility 600 , exhaust gas component measuring device 700 , and control system 800 .

[0025] The two-way breathing mask 100 includes a mask body, an air inlet, and an exhaust port. The mask body adopts a common breathing mask, which matches the outer contour of the mouth and nose of the human body. The inner edge of the mask body has a pad that contacts the patient's skin. Used to keep airtight. The air inlet communicates with one end of the gas supply branch 400, and the other end of the gas supply branch 400 is connected to the anesthesia machine 200, which has an anesthetic evaporation chamber and a gas mixing chamber 201 (which can be arranged in the a...

Embodiment 2

[0035] Such as figure 2 and 3 As shown, the main structure of the system for quantitatively measuring the intake of anesthetic agents based on inhalation anesthesia in this embodiment is similar to that of Embodiment 1, including: a two-way breathing mask 100, an anesthesia machine 200, an oxygen supply device 300, and an air supply branch 400 , exhaust branch 500 , exhaust gas recovery equipment 600 , exhaust gas component measuring device 700 , and control system 800 .

[0036] The two-way breathing mask 100 includes a mask body, an air inlet, and an exhaust port. The mask body adopts a common breathing mask, which matches the outer contour of the mouth and nose of the human body. The inner edge of the mask body has a pad that contacts the patient's skin. Used to keep airtight. The air inlet is in communication with one end of the gas supply branch 400, and the gas supply branch is connected to the anesthesia machine 200. The anesthesia machine 200 has an anesthesia evapo...

Embodiment 3

[0048] Aiming at the problems in Embodiment 2, the inventors of the present application made further improvements on the basis of Embodiment 2 and proposed another improvement. The applicant proposed a ventilator with a real-time monitoring function of anesthetic drug absorption without repeated calibration.

[0049] The main structure of the ventilator of this embodiment is similar to that of Embodiment 2, including: a two-way breathing mask 100, anesthesia machine 200, oxygen supply equipment 300, air supply branch 400, exhaust branch 500, waste gas recovery equipment 600, exhaust Gas component measuring device 700 and control system 800 .

[0050] There is a parallel measurement section for the intake branch and the exhaust branch, and at this measurement section, the intake branch and the exhaust branch are arranged in parallel, and both the intake branch and the exhaust branch have At least two transparent windows, at least one incident light window and at least one scat...

Abstract

The invention discloses a ventilator with functions of anesthesia and quantitative measurement. The ventilator comprises: a two-way breathing mask (100), an anesthesia machine (200), an oxygen supply device (300), and an air supply branch (400) , an exhaust branch (500), an exhaust gas recovery device (600), an exhaust gas component measuring device (700), and a control system (800), wherein the exhaust gas component measuring device (700) is used to measure the exhaust gas in real time The concentration of the anesthetic agent discharged in the gas branch, the control system (800) performs an integral calculation based on the concentration curve of the anesthetic agent discharged by the exhaust gas component measuring device (700), to obtain the amount of the eliminated agent.

Description

technical field [0001] The invention relates to the medical field, in particular to a ventilator with anesthesia function. Background technique [0002] In modern clinical medicine, the ventilator, as an effective means of artificially replacing the spontaneous ventilation function, has been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation. It occupies a very important position in the field of modern medicine. [0003] Anesthesia is a necessary clinical step for various operations and examinations. Inhalation anesthesia refers to the anesthesia produced by inhalation of anesthetics in a vapor or gaseous state through the respiratory tract. It is called inhalation anesthesia, and isoflurane is commonly used as an anesthetic. [0004] Another commonly used anesthetic is sevoflurane, which is most suitable for the induction of anesthesia in children. ...
