Description

Technical Field

[0001] This utility model relates to the field of oral treatment devices, specifically to a structure for indicating injection speed. Background Technology

[0002] In the field of modern oral treatment and restoration, oral material syringes are key tools used to precisely inject fluid materials (such as restorative resins) into the target areas of the oral cavity or teeth, and their operation directly affects the quality of restoration.

[0003] Currently, existing syringes are difficult to effectively assess injection speed. When using manual syringes to inject materials, dentists mainly rely on their own experience and feel to control the injection speed. This method lacks precise quantitative standards, making it difficult to ensure the uniformity and stability of the injection speed throughout the procedure, thus limiting the level of precision in dental prosthetic treatment.

[0004] Taking the restoration of dental caries as an example, when using an existing dental material syringe to inject restorative material, an inappropriate injection speed can easily cause a series of problems: if the injection speed is too fast, air is easily trapped in the material during the filling process, thus forming a hole; if the injection speed is too slow or uneven, the material filling will be less uniform, affecting the shape and structure of the restoration.

[0005] These problems caused by improper injection speed control can not only reduce the aesthetics and functionality of the restoration, but also lead to serious clinical consequences. For example, food debris and bacteria can easily remain in the pores and uneven areas formed during the filling process, leading to complications such as secondary caries and pulpitis, causing long-term harm to the patient's oral health.

[0006] In the existing technology, there are syringes with certain speed measurement functions, but they are special devices. Since syringes are consumable devices, the cost of use is increased. In addition, due to their complex structure, there are problems with the reliability and ease of operation.

[0007] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0008] The purpose of this invention is to provide a structure for indicating injection speed.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] An injection speed indication structure is provided for a syringe, the syringe including a barrel and an injection handle; the injection speed control structure includes:

[0011] A fastener is provided on the cylinder;

[0012] The pressing element is fitted to the injection handle;

[0013] The speed measuring mechanism is at least connected to the pressing element;

[0014] A prompting element is provided on the fixing element and electrically connected to the speed measuring mechanism;

[0015] The injection speed control structure has a speed measurement state:

[0016] In the speed measurement state, the pressing element and the injection handle move synchronously. The speed measuring mechanism detects the moving speed of the pressing element and transmits the speed measurement information to the prompting element. The prompting element prompts the current injection speed based on the speed measurement information.

[0017] When the syringe is in operation, the barrel remains stationary while the injection handle moves to inject the syringe. At this time, the fixing part and the barrel remain relatively stationary, and the pressing part and the injection handle remain relatively stationary.

[0018] In the above scheme, the operator applies force to the pressing component, which drives the injection handle to complete the injection operation. During the injection process, the speed measuring mechanism detects the moving speed of the pressing component to obtain the injection speed of the injection handle. The prompting component prompts the operator with the current injection speed based on the speed measuring information of the speed measuring mechanism. The operator adjusts the force applied to the pressing component in a timely manner according to the prompting component, thereby adjusting the injection speed.

[0019] With the coordination of the speed measuring mechanism and the prompting device, the operator can promptly and clearly know the current injection speed, replacing the traditional method of judging the injection speed by personal perception. This helps to ensure the uniformity and stability of the injection speed, promotes precise injection, and improves the treatment effect and patient experience when the syringe is used for oral treatment.

[0020] The indicator is positioned on a fixed component, close to the speed measuring mechanism, so that operators can receive the indicator information in a timely manner.

[0021] The data transmission method is the existing setting and will not be explained in detail here.

[0022] Current injection rate refers to the injection rate at a specific point in time.

[0023] In some implementations, the prompting device is a prompter, which works as follows: a threshold is preset, and when the injection speed approaches or exceeds the threshold, the speed measuring mechanism sends a signal to the prompter, which then issues a prompt signal (such as flashing red light) to inform the operator that the current injection speed is too fast, thereby achieving reasonable control of the injection speed.

[0024] A further technical solution is provided, wherein the speed measuring mechanism includes:

[0025] A speed measuring rod is provided on the pressing component and has a grating structure;

[0026] A grating speed sensor is mounted on the fixing component and electrically connected to the prompting component;

[0027] In speed measurement mode, the speed measuring rod moves synchronously with the pressing component, and the grating speed sensor detects the moving speed of the pressing component based on the grating structure.

[0028] This embodiment provides a specific speed measurement method, namely, grating speed measurement. During the speed measurement process, the speed measuring rod and grating structure move with the pressing component, while the fixing component supports the grating speed sensor to remain stationary, providing a basis for speed measurement. This embodiment does not change the principle of grating speed measurement.

[0029] This embodiment uses grating velocimetry to measure the moving speed of the pressing component in a timely manner, ensuring that the operator knows the current injection speed in a timely manner, so as to adjust the force applied to the pressing component in a timely manner.

[0030] The grating speed sensor is an existing grating sensor.

[0031] In some embodiments, the length direction of the speed measuring rod is parallel to the length direction of the injection handle.

[0032] In a further technical solution, the pressing component is provided with a groove, and the speed measuring rod is positioned and assembled with the pressing component through the groove.

[0033] In this embodiment, the speed measuring rod and the pressing component are actually connected by a snap-fit ​​assembly, which makes the connection between the two stable and allows for quick connection and separation, making it easy to replace the speed measuring rod to ensure speed measurement accuracy and speed.

[0034] In some implementations, the speed measuring rod has an L-shaped structure.

[0035] In a further technical solution, the grating speed sensor is located inside the fixing component;

[0036] The fixing component is provided with a through hole for the speed measuring rod to pass through.

[0037] The grating speed sensor is located inside the fixture, which protects the grating speed sensor while reducing the space required for this application.

[0038] The speed measuring rod can be inserted into the perforation, which reduces the space required for this application. On the other hand, this plug-in connection allows for indirect connection between the fixing component and the pressing component during the non-injection stage, facilitating the placement of the injection speed control structure.

[0039] In some embodiments, the speed measuring rod is slidably mounted on a fixed component.

[0040] The speed measuring rod is supported by a fixing component, which in turn supports the pressing component, avoiding the need for the pressing component to be fixed to the injection handle, thereby achieving rapid separation of the pressing component and the injection handle.

[0041] In a further technical solution, the fastener includes an elastic fitting portion, which is fastened and assembled with the cylindrical body.

[0042] The close-fitting part can be a ring structure or an arc structure.

[0043] The snap-fit ​​assembly not only achieves stable assembly of the fastener and the cylinder, but also facilitates separation of the two, thereby making it easy to remove the injection speed control structure from the cylinder. This allows the present invention to be used in combination with different syringes according to usage requirements, thereby reducing usage costs. In addition, the injection speed control structure can also be stored separately, extending its service life.

[0044] The flexible setting can be achieved using elastic materials such as rubber.

[0045] In a further technical solution, the fixing member is provided with a fixing groove for fixing the prompting member.

[0046] In this embodiment, the fastener can be used to fix both the speed measuring mechanism and the prompting component, thereby improving the utilization of the fastener.

[0047] When the indicator is placed in the fixed slot, no additional structure is needed to achieve the purpose of the indicator being close to the speed measuring mechanism, which reduces structural costs and makes it easier for operators to receive the indicator information in a timely manner.

[0049] The terms "connection" or "positioning" as used in this article can refer to two or more components or devices making direct physical contact with each other, or making indirect physical contact with each other, or to two or more components or devices operating or moving with each other.

[0050] The terms “include,” “including,” and “have” used in this article are all open-ended, meaning they include but are not limited to.

[0051] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.

[0053] The working principle and advantages of this utility model are as follows:

[0054] When the syringe is in operation, the barrel remains stationary while the injection handle moves to inject the syringe. At this time, the fixing part and the barrel remain relatively stationary, and the pressing part and the injection handle remain relatively stationary.

[0055] In this application, the operator applies force to the pressing component, which drives the injection handle to complete the injection operation. During the injection process, the speed measuring mechanism detects the moving speed of the pressing component to obtain the injection speed of the injection handle. The prompting component prompts the operator with the current injection speed based on the speed measuring information of the speed measuring mechanism. The operator adjusts the force applied to the pressing component in a timely manner according to the prompting component, thereby adjusting the injection speed.

[0056] With the coordination of the speed measuring mechanism and the prompting device, the operator can promptly and clearly know the current injection speed, replacing the traditional method of judging the injection speed by personal perception. This helps to ensure the uniformity and stability of the injection speed, promotes precise injection, and improves the treatment effect and patient experience when the syringe is used for oral treatment.

[0057] When this application is used for the restoration of dental caries, the controlled injection speed can prevent the formation of pores due to air entrapment during the filling process, and can also prevent the shape and structure of the restoration from being affected by poor uniformity of material filling. This ensures the aesthetics and functionality of the restoration while avoiding subsequent clinical consequences.

[0058] This application allows for direct mounting on existing syringes and is compatible with different syringes. It can also be stored separately, thereby reducing usage costs and extending service life. The application features a simple structure, improving reliability and ease of operation.

[0059] The indicator is positioned on a fixed component, close to the speed measuring mechanism, so that operators can receive the indicator information in a timely manner. Attached Figure Description

[0063] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0064] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.

[0066] See Figures 1-2 An injection speed indication structure is provided for a syringe 1, the syringe 1 including a barrel 11 and an injection handle 12; the injection speed control structure includes:

[0067] Fixing member 2 is provided on the cylinder 11;

[0068] The pressing element 3 is attached to the injection handle 12;

[0069] The speed measuring mechanism 4 is at least connected to the pressing member 3;

[0070] The prompting component 5 is disposed on the fixing component 2 and electrically connected to the speed measuring mechanism 4;

[0071] The injection speed control structure has a speed measurement state:

[0072] In the speed measurement state, the pressing element 3 moves synchronously with the injection handle 12. The speed measuring mechanism 4 detects the moving speed of the pressing element 3 and transmits the speed measurement information to the prompting element 5. The prompting element 5 prompts the current injection speed based on the speed measurement information.

[0073] When the syringe 1 is working, the barrel 11 remains stationary while the injection handle 12 moves to perform the injection operation. At this time, the fixing member 2 and the barrel 11 remain relatively stationary, and the pressing member 3 and the injection handle 12 remain relatively stationary.

[0074] In the above scheme, the operator applies force to the pressing part 3, and the pressing part 3 drives the injection handle 12 to complete the injection operation. During the injection process, the speed measuring mechanism 4 obtains the injection speed of the injection handle 12 by detecting the moving speed of the pressing part 3. The prompting part 5 prompts the operator with the current injection speed based on the speed measuring information of the speed measuring mechanism 4. The operator adjusts the force applied to the pressing part 3 in time according to the prompting part 5, thereby adjusting the injection speed.

[0075] With the cooperation of the speed measuring mechanism 4 and the prompting component 5, the operator can promptly and clearly know the current injection speed, replacing the traditional method of judging the injection speed by personal perception. This helps to ensure the uniformity and stability of the injection speed, promotes precise injection, and improves the treatment effect and patient experience when the syringe 1 is used for oral treatment.

[0076] When this application is used for the restoration of dental caries, the controlled injection speed can prevent the formation of pores due to air entrapment during the filling process, and can also prevent the shape and structure of the restoration from being affected by poor uniformity of material filling. This ensures the aesthetics and functionality of the restoration while avoiding subsequent clinical consequences.

[0077] This application allows for direct mounting on existing syringes and is compatible with different syringes. It can also be stored separately, thereby reducing usage costs and extending service life. The application features a simple structure, improving reliability and ease of operation.

[0078] The prompting element 5 is located on the fixing element 2 so that it is close to the speed measuring mechanism 4, making it convenient for the operator to receive the prompting information from the prompting element 5 in a timely manner.

[0079] The data transmission method is the existing setting and will not be explained in detail here.

[0080] Speed ​​measurement information can be transmitted in real time or selectively.

[0082] In some embodiments, the prompting element 5 is a prompter, which operates as follows: a threshold is preset, and when the injection speed approaches or exceeds the threshold, the speed measuring mechanism 4 sends a signal to the prompter, which then emits a prompt signal (such as flashing red light) to inform the operator that the current injection speed is too fast, thereby achieving reasonable control of the injection speed. The prompting element 5 can be selected according to actual needs, such as a prompter with an indicator light.

[0083] In some embodiments, the prompting element 5 is an audible or / and visual prompting element (such as a buzzer, LED light, etc.).

[0084] In this embodiment, the speed measuring mechanism 4 includes:

[0085] Speed ​​measuring rod 41 is provided on the pressing member 3 and is provided with grating structure 42;

[0086] A grating speed sensor 43 is disposed on the fixing member 2 and electrically connected to the prompting member 5;

[0087] In the speed measurement state, the speed measuring rod 41 moves synchronously with the pressing member 3, and the grating speed sensor 43 detects the moving speed of the pressing member 3 according to the grating structure 42.

During the speed measurement process, the speed measuring rod 41 and the grating structure 42 move with the pressing member 3, while the fixing member 2 supports the grating speed sensor 43 to remain stationary, providing a basis for speed measurement. This embodiment does not change the principle of grating speed measurement.

[0090] In this embodiment, the moving speed of the pressing component 3 is measured in a timely manner using a grating velocimetry method, so that the operator can know the current injection speed in a timely manner and thus adjust the force applied to the pressing component 3 in a timely manner.

[0099] The speed measuring rod 41 can be inserted into the perforation 21, which reduces the space required for this application. On the other hand, this plug-in connection allows for indirect connection between the fixing member 2 and the pressing member 3 during the non-injection stage, facilitating the placement of the injection speed control structure.

[0100] In some embodiments, the speed measuring rod 41 is slidably mounted on the fixing member 2.

[0101] The speed measuring rod 41 is supported by the fixing part 2, which in turn supports the pressing part 3, avoiding the need for the pressing part 3 to be fixed to the injection handle 12, thereby achieving rapid separation of the pressing part 3 and the injection handle 12.

[0102] In this embodiment, the fastener 2 includes an elastic fastening part 22, which is fastened and assembled with the cylinder 11.

[0103] The close-fitting part 22 can be a ring structure or an arc structure.

[0104] The snap-fit ​​assembly not only achieves stable assembly of the fixing part 2 and the cylinder 11, but also facilitates separation of the two, thereby making it easy to remove the injection speed control structure from the cylinder 11.
