Description

TECHNICAL FIELD

[0001] The utility model relates to wrist nerve treatment field, especially wrist nerve position measurement and matching electrode type ruler. BACKGROUND

[0002] Electrical energy can be delivered transcutaneously via electrodes on the skin surface with a neurostimulation system to stimulate peripheral nerves, such as, by way of non-limiting example, the median, radial, and / or ulnar nerves in the upper extremity.

[0003] Electrical stimulation of these nerves has been shown to provide therapeutic benefits for a variety of conditions, including, but not limited to, movement disorders (including, but not limited to, essential tremor, Parkinsonian tremor, postural tremor, and multiple sclerosis), urological conditions, gastrointestinal conditions, cardiac conditions, and inflammatory conditions, among others.

[0004] Transcutaneous electrical nerve stimulation belongs to peripheral nerve electrical stimulation treatment technology. Since transcutaneous electrical nerve stimulation has the advantages of non-invasiveness, non-invasiveness, easy operation, good tolerance, short-acting, no side effects, low price and the like, it has become a hot spot of clinical application research and is widely used.

[0005] The wrist nerve stimulator is a small wearable transcutaneous electrical stimulation device that is worn on the wrist. By using the electrode patch closely around the wrist, the median nerve, radial nerve, and / or ulnar nerve distributed around the wrist are stimulated according to certain parameters and rules to achieve the purpose of treatment.

[0006] The relative distances between the radial nerve, median nerve, ulnar nerve, and center of the back of the wrist distributed at the wrist may vary due to individual differences (such as body type, fat content, muscle development, skeletal structure, etc.). If multiple separate electrode patches are used for treatment, matching needs to be performed before each treatment, which is very cumbersome to operate, and each operation will have some deviation, affecting the treatment effect.

[0007] Patent CN202310595835.5 provides a wrist nerve stimulator and its use method. A plurality of hydrogel electrode pieces are arranged on a long strip-shaped non-woven fabric to form a wet electrode strip. A large amount of data is collected for analysis, and multiple electrode models are configured. Each model defines the relative distance between the radial nerve, median nerve, ulnar nerve, and center of the back of the wrist, which can meet the precise matching of most patients at the wrist nerve.

[0008] The existing electrode matching method is that a doctor finds the nearest position of the nerve in the wrist on the surface of the wrist according to the instruction of wrist nerve anatomy, such as the median nerve, radial nerve, ulnar nerve, center of the back of the wrist, marks the skin surface with a marker pen after finding it, measures the distance with a common flexible ruler, records the distance between the median nerve, radial nerve, ulnar nerve and the center of the back of the wrist with a pen, compares the recorded data with the data of each model of the electrode wrist strap, and finds the appropriate electrode model for matching.

[0009] However, in the actual use process, this distance measurement method has great disadvantages:

[0010] 1. The data measurement is artificial recording, and this recording method relying on memory is prone to omissions, for example, under long-time work, the probability of recording error data is relatively large due to fatigue problems, and the efficiency is low;

[0011] 2. The comparison method is not only cumbersome and not intuitive, but also prone to errors: the recorded data are compared with the electrode wrist strap model one by one, which leads to a high frequency of checking and cannot select the corresponding electrode wrist strap in time; in addition, this artificial frequent checking method is also prone to misjudgment, which makes the accuracy rate of model selection be in a relatively low situation;

[0012] 3. The difference between the models is that the distances between the nerves are not the same, but the distances between the nerves of some patients can meet the requirements of multiple models, and obviously, it is not intuitive to see which model is the best choice for the current patient by using the existing flexible ruler;

[0013] 4. The existing flexible ruler is opaque, and the flexible ruler is easy to block the position of the nerve when measuring the distance between the nerves, so it is necessary to adjust the flexible ruler again when the position of the nerve is not determined, which is quite inconvenient for artificial measurement;

[0014] 5. The scale in the flexible ruler is not used for measuring the distance between the nerves, and it is necessary to measure multiple times in order to obtain the correct reading value, which is inconvenient to operate and low in efficiency. Practical new type content

[0015] To solve the above problems, the utility model provides a wrist nerve position measurement and electrode model pairing ruler, which does not need artificial recording of the current measurement value, and reduces the artificial recording steps.

[0016] The utility model provides a wrist nerve position measurement and electrode model pairing ruler, which does not need to compare the recorded data with the model one by one, and can select the corresponding electrode wrist strap in time on the ruler.

[0017] The utility model provides a wrist nerve position measurement and the ruler of matching electrode model, the scale value on the ruler records has corresponding model, can intuitively see optimal model, makes the selection to model fast.

[0018] The utility model provides a wrist nerve position measurement and the ruler of matching electrode model, the soft ruler is made of transparent material, can intuitively see nerve position, reduces the number of readjusting soft ruler.

[0019] The utility model provides a wrist nerve position measurement and the ruler of matching electrode model, the measurement times of the distance between nerves are few, and a large amount of measurement time is saved.

[0020] In order to realize the above-mentioned purpose, the utility model adopts technical scheme, a wrist nerve position measurement and the ruler of matching electrode model contain the ruler body, its characterized in that, the ruler body is divided into wrist dorsal center measurement area, radial nerve measurement area, median nerve measurement area, ulnar nerve measurement area in proper order, the first number pattern of zero is equipped in median nerve measurement area, and the first number pattern and the second number pattern that the first number pattern and the second number pattern of wrist dorsal center measurement area, radial nerve measurement area, ulnar nerve measurement area are equipped with respectively constitute number scale value, the ruler body still is equipped with multiple sets of identification patterns on each area, and the identification pattern is partially corresponding between identification patterns, and is distributed in the periphery of number scale value, still with number scale value, the identification pattern is composed of symmetrical indicator.

[0021] Further, the back of the ruler body is provided with double-sided adhesive tape.

[0022] Further, the double-sided adhesive tape is provided with a layer of hand-tearable adhesive.

[0023] Further, the ruler body is made of PVC or PET material.

[0024] Further, the ruler body is attached with a surface treatment agent.

[0025] The utility model has the advantages of:

[0026] 1. The ruler body is divided into multiple measurement areas, each area is separately provided with a number pattern, when measuring the distance between nerves, the corresponding electrode wristband model can be quickly known according to the number scale value and the identification pattern, manual recording means is saved, and the possibility of error is reduced.

[0027] 2. Meanwhile, the number pattern and the identification pattern are used together, without the need of screening the model, the process of measuring data and signal matching is saved, the whole wearing process is optimized, and the wearing efficiency is improved.

[0028] 3. Setting multiple sets of identification patterns can reflect which type of electrode wristband model the current measured nerve position can match, and the indicator extends along the length direction of the ruler body, according to the degree of correspondence between the nerve position and the identification pattern, it can be quickly judged which type is the most suitable for use.

[0029] 4. The ruler itself adopts a transparent material, which is beneficial to see the position of the nerve, ensures the accuracy of measurement, and reduces the number of times of adjusting the flexible ruler.

[0030] 5. The wrist back center measurement area, radial nerve measurement area, median nerve measurement area and ulnar nerve measurement area are sequentially arranged, and in the median nerve measurement area, a first indicating pattern as a zero position is arranged, and such design for specific use environment can see their measurement distance in time without the need of calculation.
