Local anaesthesia range measuring apparatus

Abstract

The invention relates to a local anaesthesia range measuring apparatus. According to the invention, monitoring probes are connected with a switcher by extension tubes; the switcher is connected with a syringe; a plurality of monitoring probes are provided; water bags are arranged in the monitoring probes and are communicated with the extension tubes; the extension tubes are respectively communicated with a plurality of peripheral connectors on the switcher and correspond to the peripheral connectors one by one; a joint of the syringe is communicated with a central connector of the switcher. The local anaesthesia range measuring apparatus overcomes the respective defects of existing needle-punching method and electroporation method. According to the invention, use of the switcher can ensure that a connector of the syringe is only selectively communicated with one path without being communicated with other paths each time, i.e. only the skin at one position is stimulated each time; accuracy of a measurement result is ensured; the local anaesthesia range measuring apparatus is safe and noninvasive and has no damage; possibilities of burn, difficulty in breathing, muscle twitches and cardiac arrest which are caused by the electroporation method are avoided; an anesthesia level is continuously monitored; both ice and heat sensation stimulations can be implemented; the local anaesthesia range measuring apparatus can be applied on the aspect of measurement on the algesia level in the orthopedics department and the neurology and neurosurgery departments.

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
