local anesthesia range tester

Abstract

The invention relates to a local anesthesia range measuring device. In the present invention, the monitoring probe is connected to the switcher through the extension tube, and the switcher is connected to the syringe; there are multiple monitoring probes, and water bladders are connected to the extension tube; the extension tubes are respectively connected to a plurality of peripheral interfaces on the switcher and one One correspondence; the connector of the syringe communicates with the central interface of the switch. The invention overcomes the respective defects in the existing acupuncture method and electric shock method. The use of the switcher of the present invention can ensure that the interface of the syringe is only selectively connected to one path and blocked from other paths each time, that is, only one part of the skin is selectively stimulated each time, ensuring accurate measurement results, safe, non-invasive, and harmless, avoiding It eliminates burns, dyspnea, muscle twitching, and cardiac arrest caused by electric shock methods. Continuous monitoring of the anesthesia level can be implemented with ice and heat stimulation. It can be used in the measurement of pain levels in orthopedics and neurosurgery.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a local anesthesia range measuring device. Background technique [0002] Before the present invention was made, the existing methods for judging the level of anesthesia after intraspinal anesthesia or nerve block anesthesia mainly included: acupuncture and electric shock. The former often uses sharp needles to test the patient's skin. The disadvantages are: 1. There is a risk of puncturing the skin of doctors and patients, which establishes a transmission channel for blood-borne diseases, and especially increases the panic between doctors and patients about diseases such as hepatitis C and AIDS; 2. Acupuncture patients increase the psychological fear burden of patients, and this contradiction is especially obvious for people with sharp instrument phobia; 3. It is not easy to grasp the strength of the implementer, the stimulation intensity cannot be quantified, and the anesthesi...

The former often uses sharp needles to test the patient's skin. The disadvantages are: 1. There is a risk of puncturing the skin of doctors and patients, which establishes a transmission channel for blood-borne diseases, and especially increases the panic between doctors and patients about diseases such as hepatitis C and AIDS; 2. Acupuncture patients increase the psychological fear burden of patients, and this contradiction is especially obvious for people with sharp instrument phobia; 3. It is difficult to grasp the strength of the implementer, the stimulation intensity cannot be quantified, and the anesthesia range cannot be compared objectively; Release "safe" current to stimulate the skin. The intensity of the current passed by the human body during the electric shock determines whether it will cause damage to the body. Generally, when the current with a frequency of 50-60 Hz passes through the human body, the current intensity is 1mA and there is tingling pain. sense

However, more than 20mA can cause muscle contraction, local burns, breathing difficulties, and even cardiac arrest

Years of clinical observation have found that there is a lack of scientific and effective intraoperative monitoring of the anesthesia plane. The usual practice is that the anesthetist lifts the surgical sterile towel and pinches the patient's skin with his bare hands. This will undoubtedly hinder the operation of the operator and violate the principle of asepsis. There is an increased risk of postoperative infection, and there are not a few cases of clinically causing postoperative infection
