Description

Technical Field

[0001] The utility model relates to a detection device, in particular to a detection instrument for preventing needles from being left unplugged. Background Art

[0002] When performing acupuncture, filiform needles need to be inserted into the patient's body at a certain angle, and acupuncture techniques such as twirling and lifting-thrusting are used to stimulate specific parts of the human body to achieve the purpose of treating diseases. When a large number of filiform needles are needed during the treatment process, due to the relatively small structure of the filiform needles, it is difficult to detect and discover, and the phenomenon of missing needles is likely to occur. Sometimes, when a broken needle occurs during the treatment process and the user cannot discover it in time, it is likely to cause medical safety accidents. Therefore, there is an urgent need for a detector that can prevent needles from being left unplugged. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a detection instrument for preventing needles from being left unplugged, so as to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or create conditions.

[0004] The solution of the utility model to solve its technical problems is:

[0005] A detection instrument for preventing needles from being left unplugged, comprising: a detection cylinder; a detection coil, which is arranged around the inner side of the detection cylinder; a power supply assembly, which is arranged in the detection cylinder, and the power supply assembly is electrically connected to the detection coil; an alarm, which is arranged in the detection cylinder, and the alarm is electrically connected to the power supply assembly.

[0006] This technical solution has at least the following beneficial effects: The detection coil is arranged around the inner side of the detection cylinder. During operation, the power supply assembly supplies power to the detection coil and the alarm. When the detection coil is energized, it generates a magnetic field. Use the detection cylinder to approach the acupuncture position of the patient. When there is still a filiform needle at the acupuncture position, the filiform needle will affect the original magnetic field of the detection coil. At this time, the alarm works to give a prompt. In this way, it is convenient for the user to know whether there is a situation of needles being left unplugged, improving the safety during medical operations, and the overall structure is simple, convenient to carry, and has strong practicability.

[0007] As a further improvement of the above technical solution, an annular groove is arranged on the inner side of the detection cylinder, and the detection coil is located in the annular groove. An annular groove for installation and storage is arranged on the inner side of the detection cylinder, and the detection coil is installed in the annular groove, which can better position the wire arrangement of the detection coil, reduce the exposure, thereby protecting the detection coil and improving the overall appearance.

[0008] As a further improvement of the above technical solution, a connecting ring is detachably connected to the notch of the annular groove of the detection cylinder. When it is necessary to install the detection coil, the connecting ring is removed from the detection cylinder to expose the annular groove, and then the connecting ring is reinstalled into the detection cylinder to cover the annular groove, so as to further improve the protection effect on the detection coil and reduce the exposure of the structure.

[0009] As a further improvement of the above technical solution, a partition plate is connected inside the detection cylinder. The partition plate divides the interior of the detection cylinder into a front cavity and a rear cavity in the front-rear direction. The detection coil is connected to the inner side of the rear cavity, and the power supply assembly and the alarm are respectively connected to the front cavity. The partition plate divides the space inside the detection cylinder into a front cavity and a rear cavity in the front-rear direction. At this time, the detection coil mainly used for detecting the acupuncture needle is installed in the rear cavity, and the power supply assembly and the alarm are installed in the front cavity. After dividing the internal space in the front-rear direction in this way, it is convenient to manage the electrical components by zones and improve the rationality of the structure installation.

[0010] As a further improvement of the above technical solution, an end cover is detachably connected to the front end of the detection cylinder. After the electrical components such as the power supply assembly and the alarm are installed in the front cavity, the end cover is then connected to the front end of the detection cylinder to cover and seal the space inside the front cavity, better protecting the electrical components inside the front cavity.

[0011] As a further improvement of the above technical solution, the alarm includes a lamp body connected to the front cavity. A light-transmitting hole is provided on the end cover, and a partition net is provided in the light-transmitting hole. When the detection coil detects an acupuncture needle, the lamp body works and emits light outwards through the light-emitting hole on the end cover, so as to visually remind the user.

[0012] As a further improvement of the above technical solution, the alarm includes a buzzer connected to the front cavity. When the detection coil detects an acupuncture needle, the buzzer works to emit a sound, so as to aurally remind the user and further improve the use experience.

[0013] As a further improvement of the above technical solution, a handle is connected to the outside of the detection cylinder. During use, the user can hold the handle, thus facilitating the movement of the detection cylinder and improving the operation convenience.

[0014] As a further improvement of the above technical solution, the handle includes a connecting rod and a connecting sleeve. One end of the connecting rod is connected to the outside of the detection cylinder, and the connecting sleeve is threadedly connected to the other end of the connecting rod. One end of the connecting rod is fixed to the handle, and the other end is threadedly connected with a connecting sleeve. During use, the threaded mating position of the connecting sleeve can be adjusted according to the use needs, so as to form handles of different lengths and flexibly adapt to different use lengths.

[0015] As a further improvement of the above technical solution, a handle is connected to the outside of the detection cylinder. The detection cylinder can be hung on an external structure, such as a wall surface, through the handle, so as to facilitate placement management when not in use. Description of the Drawings

[0024] In the description of the present utility model, unless otherwise clearly defined, words such as "set", "installed", "connected", etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0025] Referring to Figure 1 , a detection device for preventing needle omission, includes a detection cylinder 100, a detection coil, a power supply component and an alarm 200. Among them, the detection coil is disposed around the inner side of the detection cylinder 100, the power supply component is disposed in the detection cylinder 100, the power supply component is electrically connected to the detection coil, the alarm 200 is disposed in the detection cylinder 100, and the alarm 200 is electrically connected to the power supply component.

[0026] As can be seen from the above, the detection coil is disposed around the inner side of the detection cylinder 100. During operation, the power supply component supplies power to the detection coil and the alarm 200. When the detection coil is energized, a magnetic field is generated. Use the detection cylinder 100 to approach the acupuncture position of the patient. When there is still a filiform needle at the acupuncture position, the filiform needle will affect the original magnetic field of the detection coil. At this time, the alarm 200 works to give a prompt. In this way, it is convenient for the user to know whether there is a situation of missed extraction of the filiform needle, improving the safety during medical operations, and the overall structure is simple, convenient to carry, and has strong practicability.

[0027] Naturally, in order to receive signals and send control instructions to the alarm 200, the power supply component further includes a controller. The controller is signal-connected to the detection coil and the alarm 200. When the filiform needle affects the original magnetic field generated by the detection coil, the controller receives the signal and sends an instruction to the alarm 200 to control the opening or closing of the alarm 200.

[0028] When installing the detection coil in the detection cylinder 100, in order to reduce the exposure of the detection coil and better install and position the detection coil, in this embodiment, a circular groove is provided on the inner side of the detection cylinder 100, and the detection coil is located in the circular groove. A circular groove for installation and storage is provided on the inner side of the detection cylinder 100. Installing the detection coil in the circular groove can better position the wire arrangement of the detection coil, reduce the exposure, thereby protecting the detection coil and improving the overall appearance.

[0029] The detection coil is installed into the annular groove. In order to better protect the detection coil and reduce its exposure, in this embodiment, a connecting ring 110 is detachably connected to the notch of the annular groove of the detection cylinder 100. For example, the connecting ring 110 can be pushed axially into the detection cylinder 100 along the axis of the detection cylinder 100 and connected to the detection cylinder 100 through a buckle. Or after the connecting ring 110 is pushed axially into the detection cylinder 100 along the axis of the detection cylinder 100, the connecting ring 110 is further fixed in the detection cylinder 100 by driving in connecting parts such as screws or bolts. When it is necessary to install the detection coil, the connecting ring 110 is removed from the detection cylinder 100 to expose the annular groove, and then the connecting ring 110 is reinstalled into the detection cylinder 100 to cover the annular groove, so as to further improve the protection effect on the detection coil and reduce the exposure of the structure.

[0030] In the above embodiment, the power supply assembly and electrical components such as the alarm 200 can be installed inside the detection cylinder 100, or directly installed outside the detection cylinder 100. In order to better arrange the structures such as electrical components reasonably, in this embodiment, as Figure 3 shown, a partition 120 is connected inside the detection cylinder 100. The partition 120 divides the interior of the detection cylinder 100 into a front cavity and a rear cavity in the front-back direction. The detection coil is connected to the inner side of the rear cavity, and the power supply assembly and the alarm 200 are respectively connected to the front cavity. In practical applications, if it is necessary to connect the wire of the detection coil to the power supply assembly, a hole can be opened in the partition 120, and then the wire is passed forward through the opening position into the front cavity to realize electrical connection with the power supply assembly. The partition 120 divides the space inside the detection cylinder 100 into a front cavity and a rear cavity in the front-back direction. At this time, the detection coil mainly used to detect the filiform needle is installed in the rear cavity, and the power supply assembly and the alarm 200 are installed in the front cavity. After the internal space is divided in the front-back direction in this way, it is convenient to manage the electrical components in zones and improve the rationality of the structure installation.

[0031] As Figure 2 shown, further, a end cap 300 is detachably connected to the front end of the detection cylinder 100. For example, the end cap 300 can be connected to the front end of the detection cylinder 100 through a buckle, or the end cap 300 can be connected to the front end of the detection cylinder 100 through a thread. After the power supply assembly and electrical components such as the alarm 200 are installed in the front cavity, the end cap 300 is connected to the front end of the detection cylinder 100, which can cover and seal the space inside the front cavity and better protect the electrical components inside the front cavity.

[0032] The alarm 200 is mainly used to give an alarm signal and can change its appearance to give a warning. Specifically, the alarm 200 includes a lamp body connected to the front cavity. At this time, the lamp body is also signal-connected to the controller. A light-transmitting hole is provided on the end cap 300, and a separator net 310 is provided in the light-transmitting hole. When the detection coil detects a fine needle, the lamp body works and emits light outwards from the light-emitting hole on the end cap 300, so as to visually remind the user. In practical applications, the shape of the lamp body can be various. For example, it is arranged around the inner side of the front cavity to form a ring-shaped light belt, and the light emitted by the lamp body can be emitted outwards through the light-transmitting hole. In order to improve the user experience, the entire detection cylinder 100 can be made of a light-transmitting material, and it is easier to observe its changes when the lamp body works; in addition, when the lamp body is a block, the lamp body can be directly arranged at a position facing the light-transmitting hole, so as to increase the brightness of the light emitted outwards through the light-transmitting hole and more easily remind the user.

[0033] In some embodiments, the alarm 200 can emit a sound for warning. Specifically, the alarm 200 includes a buzzer connected to the front cavity. Similarly, the buzzer is also signal-connected to the controller. When the detection coil detects a fine needle, the buzzer works to emit a sound, so as to remind the user audibly and further improve the user experience.

[0034] In the above embodiments, when it is necessary to move the detection cylinder 100, the user can directly hold the detection cylinder 100 for moving operation. In order to move the detection cylinder 100 more conveniently, in this embodiment, a handle is connected to the outside of the detection cylinder 100. When in use, the user can hold the handle, so as to conveniently move the detection cylinder 100 and improve the convenience of operation.

[0035] The handle can directly be a rod connected to the outside of the detection cylinder 100. In order to conveniently adjust the length of the handle during use, in this embodiment, the handle includes a connecting rod 410 and a connecting sleeve 420. One end of the connecting rod 410 is connected to the outside of the detection cylinder 100, and the connecting sleeve 420 is threadedly connected to the other end of the connecting rod 410. One end of the connecting rod 410 is fixed to the handle, and the other end is threadedly connected with a connecting sleeve 420. When in use, the threaded mating position of the connecting sleeve 420 can be adjusted according to the use needs, so as to form handles of different lengths and be flexibly applicable to different use lengths.

[0036] In some embodiments, a handle 500 is connected to the outside of the detection cylinder 100. The handle 500 is connected to a position on the outside of the detection cylinder 100 away from the handle. Through the handle 500, the entire detection cylinder 100 can be hung on an external structure, such as a wall surface, so as to facilitate placement management when not in use.

[0037] The above has specifically described the preferred embodiments of the present utility model. However, the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model. These equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
