Abstract
The utility model discloses a muscle tension sensor with features of simple structure and easy clinical use, comprising a sensing element and its signal leading-out line; wherein the sensing element is a piezodielectric sensor and encapsulated in a muscle looseness monitoring glove; the muscle looseness monitoring glove is formed by a soft non-conductive material and comprises a thumb cutting sleeve component, a thumb cutting sleeve component and an arc connection part for connecting the thumb cutting sleeve component and the thumb cutting sleeve component; the sensing element is arranged in the arc connection part; a leading-out hole of the signal leading-out line is arranged on the muscle looseness monitoring glove. The muscle looseness monitoring scheme of the muscle tension sensor breaks through the prior acceleration monitoring and pressure power-holding way and collects the myoelectricity reaction of the muscle using the piezoelectricity sensing way and the sensing slice is placed in the soft non-conductive material and deforms along with the action of the glove. In addition, the clinical operation posture has no effect on the use of the muscle tension sensor and it is only necessary to sleeve the sensor on the hand of the patient to monitor.
Description
Technical field
This utility model relates to a kind of physiological measurements pick off, more particularly relates to a kind of muscular tension pick off.
Background technology
The muscular tension pick off is a kind of important devices that is used for degree monitoring of flaccid muscles, can accurately catch the faint action of hand, the deformation of mechanical quantity can be changed into electric weight output.
In clinical general anesthesia operation process, be to have certain requirements to patient's situation of flaccid muscles.The monitoring mode of present independently monitor for muscle relaxation is monitoring acceleration or pressure grip mode: acceleration transducer is that pick off is placed on the thumb, patient's palm must be fixed during use, just can accurately monitor; The grip pressure transducer is that the induction apparatus that volume is bigger is held in the hand, and reuse twines cloth whole handbag is risen, and just can monitor.
Because this dual mode all must be fixed hand just and can accurately monitor in use, just cause in actual clinical is used, can being subjected to a lot of limitations: can select lateral position according to operative site such as a lot of operations, the ventricumbent position, the acceleration mode just can't be used like this.And usually need in the operation patient vital signs is monitored such as blood oxygen etc., also to give patient infusion, injectable drug simultaneously.If hand wrapped, certainly will influence these work, this makes and also has difficult point in the clinical use of grip pressure transducer.
In addition, the operation during these two kinds of sensing mode actual installation patient Yu hands is also cumbersome, and preparation had originally also increased workload with regard to many anaesthetists before this gave art.
The utility model content
The purpose of this utility model, promptly be to provide a kind of simple in structure, clinical easy-to-use, can not be subjected to operation position to influence, do not influence the muscular tension pick off of operation monitoring.
According to the characteristics of neuromuscular monitoring hand motion, this utility model muscular tension pick off is enclosed within hand with inductive means, in order to implement the monitoring action.Concrete technical scheme is as follows:
This muscular tension pick off includes sensing element and signal lead-out wire thereof; Described sensing element is selected piezoelectric transducer for use, and is packaged in the neuromuscular monitoring glove;
Described neuromuscular monitoring glove are made by soft electrically non-conductive material, include thumb ferrule part, forefinger ferrule part, and, the arc coupling part of connection thumb ferrule part and forefinger ferrule part; Described piezoelectric transducer promptly is arranged in this arc coupling part;
Described neuromuscular monitoring glove are provided with the leadout hole of described signal lead-out wire.
Described piezoelectric transducer preferably adopts piezoelectric membrane, especially the PVDF poly meta fluoroethylene piezoelectric film.Principle: PVDF can produce electric charge on two surfaces of thin film after being subjected to deformation, the quantity of electric charge that is produced is directly proportional with the deformation size.
In order to respond to the action with the reflection hand, described soft electrically non-conductive material is recommended to adopt silica gel, plastics or rubber, and its soft durometer is controlled according to material mixture ratio.
Described neuromuscular monitoring glove can be made the integral type parts with soft electrically non-conductive material.
As further improvement to above-mentioned neuromuscular monitoring glove, the cutting ferrule part of described thumb ferrule part and forefinger ferrule part, its inner arc and finger shape adapt, and are incomplete enclosed construction, and its two flank can fixedly encase finger and get final product.
The using method of this muscular tension pick off: described thumb ferrule part and forefinger ferrule part are fastened in respectively on the thumb and forefinger of the same palm of patient; Described arc coupling part, correspondence are positioned at the tiger position of patient's palm.After patient's hand ulnar nerve was subjected to the neuromuscular monitoring stimulus signal, hand had corresponding myoelectricity reflection.The muscular tension pick off captures This move by deformation, and exports the corresponding signal of telecommunication.
Adopt the neuromuscular monitoring scheme of this muscular tension pick off, broken through monitoring acceleration and the pressure grip mode used in the past, adopt the piezoelectric sensing mode to gather the emg response of muscle, sensing chip is placed in silica gel inside, the deformation with the glove action.And it uses can not be subjected to the influence of clinical operation position, only needs sensor sleeve can be monitored at patient's hand.

The specific embodiment
Below in conjunction with accompanying drawing this utility model muscular tension pick off is further described.
Fig. 1 and Fig. 2 are the structural representations of an embodiment of this utility model muscular tension pick off and neuromuscular monitoring glove thereof.As shown in the figure, this utility model muscular tension pick off comprises pick off 4 and signal lead-out wire 5 thereof; Described pick off 4 is packaged in the neuromuscular monitoring glove; The signal lead-out wire 5 of described pick off 4 is drawn from the leadout hole 6 on the neuromuscular monitoring glove.What described pick off adopted is the PVDF poly meta fluoroethylene piezoelectric film.
As Fig. 1, described neuromuscular monitoring glove are mainly by thumb ferrule part 1, forefinger ferrule part 2, and, the arc coupling part 3 of connection thumb ferrule part and forefinger ferrule part totally three parts is formed, available soft electrically non-conductive material (for example silica gel, plastics or rubber etc., but preferably use silica gel) is made the integral type parts; Described piezoelectric transducer 4 can be packaged in (see figure 2) in this arc coupling part 3 by shrinkage pool 9.
