Description

Technical Field

[0001] The present invention mainly relates to the field of medical devices, and in particular to a novel grip pain assessor. Background Art

[0002] According to incomplete statistics of the survey results, 50% of patients have varying degrees of pain. With the development of my country's medical industry and the World Health Organization's attention to disease pain, my country's medical and health institutions have now listed pain as the fifth vital sign, and some institutions have begun routine evaluation and trials in clinical practice.

[0003] The existing pain assessment instrument measures the patient's grip strength by having the patient hold the grip handle tightly, thereby assisting in assessing the pain value. Medical staff assess the patient's pain value based on experience and combined with the measured grip strength value. The existing grip handle is an "eight"-shaped handle, which is not easy for people with small hands to hold and apply force accurately, resulting in inaccurate grip strength measurement. In addition, the grip strength of a child can generally reach 30 pounds, and the grip strength of an adult can reach 110 pounds. There is a huge difference between the extreme values ​​of children and adults. A child's grip strength of 30 pounds is already very painful, while an adult at this time does not feel any pain. The same value does not reflect the same pain value. Medical staff cannot easily distinguish the patient's pain level through the grip strength assessment instrument, and incorrect assessment brings great risks to subsequent treatment.

[0004] In summary, existing pain assessment instruments are difficult to test pain, and it is difficult to meet a measurement standard for each patient, and the accuracy of the measurement for each patient cannot be guaranteed. Summary of the invention

[0083] The novel grip pain assessor of the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments of the present invention.

[0084] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0085] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0086] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0087] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0088] like Figure 1-Figure 8 As shown, the novel grip pain assessor comprises: a housing 1, an elastic grip piece 2 driven by the grip force of the patient for convenient gripping and measurement by the patient, and a pain indicator 3 for expressing the patient's pain index through the grip force value of the elastic grip piece 2. The elastic grip piece 2 and the pain indicator 3 are connected inside the housing 1 respectively.

[0089] In order to facilitate the patient to hold and form a stroke through gripping force, and then drive the pain indication device 3. The elastic gripping member 2 includes: a finger gripping part 21 for the patient to hold with his fingers, a palm gripping part 22 for the palm of the hand, an elastic member 23 that provides elastic thrust for holding, and a support member 24 that connects the elastic member 23 to ensure the gripping force. An elastic member 23 and a support member 24 are provided between the finger gripping part 21 and the palm gripping part 22 to ensure the reverse thrust of holding. In order to use it for different patients, different patients have different gripping forces, and there is enough gripping stroke to ensure the accuracy of measurement. The number of the support members 24 is set to be multiple, and the support members 24 are retractable members. Through the telescopic number of the support members 24, the set number of support members 24 are extended and connected to the elastic member 23 to support; ensure that different numbers of support members 24 and elastic members 23 provide reaction force to the gripping force. This satisfies the requirement that people with less gripping power are provided with fewer elastic members 23 and patients with greater gripping power are provided with a greater number of elastic members 23, thereby ensuring that all patients are within the set travel range, thereby improving measurement accuracy.

[0090] In order to facilitate the pain test, a measurement standard can be met for each patient, and the accuracy of the measurement can be guaranteed for each patient. The pain indicator device 3 includes: a connector 31 connected to the elastic grip member 2, a grip indicator 32 for measuring the patient's maximum grip value, and a pain indicator 33 for indicating the patient's pain level relative to the maximum grip value. One end of the connector 31 is connected to the elastic grip member 2, and the other end of the connector 31 is detachably connected to the grip indicator 32 and the pain indicator 33, respectively, so that the connector 31 pushes the grip indicator 32 or the pain indicator 33 to slide. That is: in the first case, the connector 31 is connected to the grip indicator 32, and the connector 31 is separated from the pain indicator 33 to measure the patient's maximum grip value. In the second case, the connector 31 is connected to the pain indicator 33 to measure the patient's pain value.

[0091] In order to facilitate the patient's finger gripping and ensure sufficient pushing force, the finger gripping part 21 comprises: a pressure piece 211 supporting the finger; and a support piece 24 fixedly connected to the lower side of the pressure piece 211.

[0092] For convenience, the number of supporting effects of the support member 24 can be adjusted. The support member 24 is an electric telescopic member. Further, in order to improve the fixing strength of the electric telescopic member, the requirement for the number of supports can be adjusted. The telescopic cylinder 241 of the electric telescopic member is fixedly connected to the lower side of the pressure member 211, and the telescopic rod 242 of the electric telescopic member is extended, and the end of the telescopic rod 242 is detachably supported and connected with the elastic member 23. By extending and retracting the electric telescopic rod, the number of effects between the electric telescopic rod and the elastic member 23 is adjusted, and then the number of elastic members 23 is adjusted to meet the requirements of patients with different gripping forces.

[0093] In order to ensure the smooth working process of the pressure piece 211 and the stability of the entire measurement, guide grooves 11 are provided on both sides of the inner wall of the housing 1, and the two ends of the pressure piece 211 extend into the guide grooves 11 and slide along the guide grooves 11; the guide grooves 11 limit the position of the pressure piece 211 to ensure the stability of the sliding of the pressure piece 211.

[0094] In order to avoid deformation of the pressure piece 211 during use, which affects the measurement accuracy, and also reduces the tightness of the connection between the pressure piece 211 and the housing 1. The pressure piece 211 includes: a pressure plate 2111 that provides pressure support and a rigid support bow 2112 that provides stable strength support for the pressure plate 2111. The two ends of the pressure plate 2111 are fixedly connected to the two ends of the support bow 2112 respectively. In order to pull the connecting piece 31, the middle part of the support bow 2112 is fixedly connected to the connecting piece 31.

[0095] In order to ensure the closedness of the internal structure and prevent external dirt from entering the shell 1 to affect the hygiene level and avoid the possibility of cross contamination, a flexible sealing cloth 15 is provided between the pressure piece 211 and the palm force part 22 to isolate the support piece 24 and the elastic piece 23 inside the shell 1.

[0096] In order to protect the patient from scratches during use and improve the comfort and gripping force of the patient during the gripping process, the finger gripping part 21 also includes: a gripping pad layer 212 for supporting the gripping fingers and a protective layer 213 for wrapping the support arch 2112. The gripping pad layer 212 is arranged on the surface of the pressure plate 2111, and the protective layer 213 is arranged on one side of the inner part of the support arch 2112. A finger extension cavity 214 is reserved between the protective layer 213 and the gripping pad layer 212 to meet the patient's finger insertion and gripping function.

[0097] In order to further improve the patient's comfort and ensure that sufficient gripping force is exerted during the gripping process, four arc-shaped finger grooves 2121 are provided on the surface of the gripping pad layer 212 .

[0098] In order to offset the effect of the gripping force and ensure the rationality of the structure of the elastic member 23, the fixed connection of the structure of the elastic member 23 is facilitated. The elastic member 23 includes: a compression spring body 231 that mainly provides support force, a pressure head 232 that cooperates with the support member 24, and a connection seat 233 that fixes the compression spring body 231. The connection seat 233 is fixedly connected to the palm force part 22, the upper side of the connection seat 233 is fixedly connected to the compression spring body 231, and the pressure head 232 is fixedly connected to the upper end of the compression spring body 231.

[0099] In order to correspond to the number of the support members 24, a plurality of pressure receiving heads 232 are provided. Further, in order to avoid interference between the working pressure receiving heads 232 and the non-working pressure receiving heads 232, arc-shaped structures are provided between adjacent pressure receiving heads 232 so that they can be smoothly staggered with each other.

[0100] In order to ensure the stability of the pressure-bearing structure, it is ensured that part of the pressure-bearing structure is always connected, thereby ensuring the compactness of the structure. The pressure-bearing head 232 is divided into: a main pressure-bearing head 2321 that is always in a working state and a secondary pressure-bearing head 2322 that can be in a non-working state. The main pressure-bearing head 2321 is fixedly connected to the pressure piece 211 through a pressure block 243 (non-retractable), and a plurality of compression spring bodies 231 are arranged between the main pressure-bearing head 2321 and the palm force part 22 for support and fixation (preferably fixed connection to ensure the stability of the structural connection). A plurality of secondary pressure-bearing heads 2322 are respectively arranged on both sides of the main pressure-bearing head 2321 (preferably the same number is arranged on both sides), the lower end of the secondary pressure-bearing head 2322 is fixedly connected to the compression spring body 231, and the upper end of the secondary pressure-bearing head 2322 is detachably supported from the lower end of the electric telescopic member; through the secondary pressure-bearing head 2322 in the working state, adjustment is achieved to meet the requirements of patients with different gripping forces.

[0101] In order to facilitate the cooperation with the auxiliary pressure head 2322. The end of the telescopic rod 242 of the electric telescopic member is fixedly connected with a pressure head 244, the size of the pressure head 244 is smaller than the size of the auxiliary pressure head 2322, and the contact surface between the pressure head 244 and the auxiliary pressure head 2322 is a flat structure. On the premise of avoiding interference with other auxiliary pressure heads 2322 in non-working states, it can closely cooperate with the auxiliary pressure head 2322 in working state to ensure sufficient restoring force.

[0102] In order to facilitate the gripping of the patient's palm, the palm force part 22 includes: a cushioning layer 221 for cushioning support, and a connecting support layer 222 for supporting and fixing the shell 1. Since the connecting support layer 222 is made of a material with relatively high hardness, it can ensure a tight connection with the shell 1, and further, it can also be stably connected with the connecting seat 233, thereby ensuring the support stability of the elastic member 23. The inner wall of the connecting support layer 222 is fixedly connected to the connecting seat 233, and both ends of the connecting support layer 222 are fixedly connected to the shell 1, and the outer wall of the connecting support layer 222 is wrapped with the cushioning layer 221.
