Description

Technical Field

[0001] This utility model belongs to the field of acupuncture technology, and specifically relates to an acupuncture needle ejection device. Background Technology

[0002] Acupuncture and moxibustion is a discipline guided by Traditional Chinese Medicine (TCM) theory, studying meridians, acupoints, and acupuncture and moxibustion methods to explore the principles of using acupuncture and moxibustion in disease prevention and treatment. It is an important component of TCM, encompassing meridians, acupoints, acupuncture and moxibustion methods, clinical treatment, acupuncture classics and texts, and experimental acupuncture. Acupuncture and moxibustion have advantages such as wide applicability, significant efficacy, convenient operation, and economic safety. The use of acupuncture needles necessitates their application, and the storage of these needles requires acupuncture needle storage devices.

[0003] Most existing acupuncture needle storage devices are simple storage boxes. When acupuncture needles are needed, the storage box lid needs to be opened and one needle needs to be taken out from a pile of needles. This is extremely inconvenient. The lid needs to be opened manually every time acupuncture needle is taken out, and it is easy to cause other acupuncture needles to become dirty when taking out needles.

[0004] For example, an acupuncture needle storage box with patent number CN202021856822.7 discloses "a housing, a sliding insert, and multiple sets of syringes. Medical staff can place a single acupuncture needle in different syringes. When using an acupuncture needle, the medical staff pulls the sliding insert upward, which drives the syringe to slide upward synchronously until the hinge at the bottom of the sliding insert slides out of the housing. At this time, the elastic ring pushes the syringe outward, and the syringe drives the acupuncture needle to rotate outward around the hinge, which makes it convenient for staff to take out a single acupuncture needle at a time." Although the above structure makes it convenient for staff to take out a single acupuncture needle at a time, placing the acupuncture needle into the box requires placing each acupuncture needle in its corresponding syringe, which is extremely time-consuming and laborious and inconvenient to use.

[0005] To address the aforementioned issues, we provide an acupuncture needle ejection device that can quickly insert and remove acupuncture needles at a time. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an acupuncture needle ejection device.

[0007] The purpose of this utility model is achieved as follows: an acupuncture needle ejection device includes a box, a needle storage cylinder is provided inside the box, an inclined block is provided at the bottom of the needle storage cylinder, and the upper surface of the inclined block is inclined to the lower left; a needle outlet hole is opened on the upper left side of the needle storage cylinder, and a capturing clip is provided inside the needle storage cylinder, which is located inside the needle storage cylinder and can move up and down and left and right.

[0008] Furthermore, a strip-shaped guide groove is provided on the left side of the inner side of the needle storage cylinder, and the strip-shaped guide groove is located below the needle outlet.

[0009] Furthermore, a strip-shaped groove is provided on the right side of the syringe, and a connecting rod is fixedly provided at the rear end of the capture clamp. The connecting rod can move through the strip-shaped groove, and the connecting rod drives the capture clamp to move up and down and left and right.

[0010] Furthermore, a guide block is fixedly provided at the right end of the connecting rod, and a strip-shaped limiting groove is provided in the middle of the guide block. A fixing rod is provided in the strip-shaped limiting groove, and the fixing rod is fixedly connected to the box body. The fixing rod and the strip-shaped limiting groove can rotate and move relative to each other.

[0011] Furthermore, a limiting block that can move left and right is provided in the strip-shaped limiting groove, and a spring is provided between the limiting block and the strip-shaped limiting groove. The right side of the limiting block is in contact with the fixing rod.

[0012] Furthermore, a positioning rod is provided on the connecting rod, and a positioning block is provided below the positioning rod. The positioning block is fixedly connected to the housing, and a positioning groove is provided on the upper surface of the positioning block. The positioning rod moves along the positioning groove.

[0013] Furthermore, a pressure rod that can move up and down is provided below the connecting rod, and the pressure rod is located inside the box.

[0014] Furthermore, a second spring is provided between the lower end of the pressure rod and the housing.

[0015] Furthermore, a second pressure rod that can move up and down is provided above the connecting rod, and the second pressure rod is located inside the box.

[0016] Furthermore, a pressing rod is provided at the upper end of the second pressure rod, and the pressing rod can move up and down through the upper surface of the box.

[0017] When using this utility model, an acupuncture needle is placed inside the needle storage cylinder. The top of the needle storage cylinder can be opened to hold the needle storage cylinder. The specific technical solution will not be described in detail. As long as the top can be opened and closed to hold the acupuncture needle, it is sufficient. Since the bottom of the needle storage cylinder has a sloping structure, the bottom of most acupuncture needles is located at the bottom of the sloping surface of the needle storage cylinder. When the acupuncture needle cylinder needs to be removed, press down on the pressing rod. The pressing rod drives the second pressing rod to move downward. The lower end of the second pressing rod and the upper end of the first pressing rod have an arc-shaped structure to reduce the friction between the second pressing rod, the first pressing rod and the connecting rod. The downward movement of the second pressing rod causes the connecting rod to rotate downward. At this time, the first pressing rod moves downward, and the second spring is compressed. While the connecting rod rotates downward, the first spring returns to its original position and, together with the fixing rod, drives the limiting block to move to the right, thereby driving the guide block to move to the left. This ensures that the capture clamp at the left end of the connecting rod is always in contact with the left side of the inner wall of the needle cylinder. When the fixing rod is in contact with the right end of the strip-shaped limiting groove, if the connecting rod continues to rotate, the capture clamp will disengage from the inner wall of the needle cylinder. At this time, the positioning rod contacts the positioning block. Due to the interaction force between the positioning rod and the positioning groove on the positioning block, the connecting rod moves to the right, causing the left end of the connecting rod to rotate downward and move to the right. At this time, the guide block moves to the right, the limiting block is compressed, and the first spring is compressed again. At this point, the capture clamp is located at the bottom of the needle reservoir, near the center. Releasing the pressing rod causes the connecting rod to move to the left due to the elastic force of spring one and the fixing rod. Simultaneously, the elastic force of spring two, combined with the fixing rod, causes the connecting rod to rotate upwards. This allows the capture clamp to rotate upwards and move to the left within the needle reservoir, thus placing one of the acupuncture needles at the bottom of the reservoir. Under the action of the capture clamp, the acupuncture needle is pressed into the strip-shaped guide groove. Before the connecting rod rotates to a horizontal position, the capture clamp, in conjunction with the strip-shaped guide groove, presses and positions the acupuncture needle. When the connecting rod continues to rotate upwards due to the elastic force of spring two (i.e., spring two drives pressing rod one, which in turn drives the connecting rod upwards), the capture clamp at the left end of the connecting rod experiences a rightward force from the acupuncture needle. This causes the guide block at the right end of the connecting rod to move to the right, compressing spring one. The capture clamp continues to rotate upwards, causing the acupuncture needle to move upwards along the strip-shaped groove, allowing its upper end to pass through the needle outlet hole, thus ejecting the acupuncture needle. (In the above structure, before the connecting rod rotates to the horizontal position, the pressure rod one, under the elastic force of the spring two, can completely rotate the connecting rod to the horizontal position, or, as needed, limit the maximum upward movement distance of the pressure rod two to ensure that the connecting rod can only rotate upward to the maximum angle to the horizontal position. Specific technical solutions are not subject to technical limitations; the specific elastic forces of the spring two and spring one can be set as needed, without further technical details, as long as the above functions are achieved.) Furthermore, the friction between the capturing clamp and the acupuncture needle cylinder is much greater than the friction between the acupuncture needle cylinder and the inner surface of the needle storage cylinder, enabling the acupuncture needle cylinder to move upward under the action of the capturing clamp. The material of the contact surface between the capturing clamp and the acupuncture needle cylinder can be selected as needed, without specific technical limitations.This application applies to acupuncture needles located inside a tube (acupuncture syringe). The acupuncture syringe has a cylindrical structure. There are many brands of tube needles on the market (with a cylindrical outer packaging), which will not be described in detail.

[0018] Beneficial effects: This application can realize the upward ejection of acupuncture needles, and the setting of pressure rod one and pressure rod two can realize the rotation of the connecting rod. The structure is simple. There are only connecting rods and capture clips in the needle storage cylinder. This structure can increase the number of acupuncture needles that can be placed in the needle storage cylinder. In addition, the setting of spring one, fixing rod, limiting block and guide block can realize the rotation and left and right movement of the connecting rod. The structure is concentrated and reduces the space occupied, which can reduce the overall size of the device and make it easy to carry. Attached Figure Description

[0027] Example 1, such as Figure 1 As shown in Figure 6, the purpose of this utility model is achieved as follows: An acupuncture needle ejection device includes a housing 1, a needle storage cylinder 3 is provided inside the housing 1, an inclined block 11 is provided at the bottom of the needle storage cylinder 3, and the upper surface of the inclined block 11 is inclined to the lower left; a needle outlet hole 2 is opened on the upper left side of the needle storage cylinder 3, and a capturing clip 13 is provided inside the needle storage cylinder 3, which is movable up and down and left and right within the needle storage cylinder 3. A strip-shaped guide groove 8 is opened on the left side of the inner side of the needle storage cylinder 3, and the strip-shaped guide groove 8 is located below the needle outlet hole 2.

[0028] The syringe 3 has a strip groove 15 on its right side. A connecting rod 12 is fixedly installed at the rear end of the capture clamp 13. The connecting rod 12 can move through the strip groove 15 and drives the capture clamp 13 to move up and down and left and right.

[0029] A guide block 1611 is fixedly installed at the right end of the connecting rod 12. A strip-shaped limiting groove is opened in the middle of the guide block 1611. A fixing rod 9 is installed in the strip-shaped limiting groove. The fixing rod 9 is fixedly connected to the housing 1. The fixing rod 9 and the strip-shaped limiting groove can rotate and move relative to each other. A limiting block 17 that can move left and right is installed in the strip-shaped limiting groove. A spring 18 is installed between the limiting block 17 and the strip-shaped limiting groove. The right side of the limiting block 17 is in contact with the fixing rod 9.

[0030] A positioning rod 19 is provided on the connecting rod 12, and a positioning block 10 is provided below the positioning rod 19. The positioning block 10 is fixedly connected to the housing 1. A positioning groove is opened on the upper surface of the positioning block 10, and the positioning rod 19 moves along the positioning groove. A vertically movable pressure rod 6 is provided below the connecting rod 12, and the vertically movable pressure rod 6 is located inside the housing 1. A spring 5 is provided between the lower end of the pressure rod 6 and the housing 1. A vertically movable pressure rod 7 is provided above the connecting rod 12, and the vertically movable pressure rod 7 is located inside the housing 1. A pressing rod 4 is provided at the upper end of the pressure rod 7, and the pressing rod 4 can move vertically and penetrates the upper surface of the housing 1.

[0031] In use, an acupuncture needle 14 is placed inside the needle storage cylinder 3. The top of the needle storage cylinder 3 can be opened to accommodate the needle storage cylinder 3. Specific technical details are omitted; the key is to allow the top to open and close for accommodating the acupuncture needle 14. Since the upper surface of the inclined block at the bottom of the needle storage cylinder 3 is inclined, most acupuncture needles 14 are located at the bottom of the inclined surface of the needle storage cylinder 3. When it is necessary to remove the acupuncture needle 14, the pressing rod 4 is pressed down. The pressing rod 4 causes the second pressing rod 7 to move downwards. The lower end of the second pressing rod 7 and the upper end of the first pressing rod 6 have an arc-shaped structure, which reduces friction between the second pressing rod 7, the first pressing rod 6, and the connecting rod 12. The downward movement of the second pressing rod 7 causes the connecting rod 12 to rotate downwards. At this time, the first pressing rod 6 moves downwards, and the second spring 5 is compressed. Simultaneously with the downward rotation of the connecting rod 12, the first spring 18 resets and, in conjunction with the fixing rod 9, causes the limiting block 17 to move to the right, thereby causing the guide block 11 to move to the left, thus allowing the connecting rod 14 to rotate downwards. 2. The capture clip 13 at the left end is always in contact with the left side of the inner wall of the syringe 3. When the fixing rod 9 is in contact with the right end of the strip-shaped limiting groove, the capture clip 13 will disengage from the inner wall of the syringe 3 if the connecting rod 12 continues to rotate. At this time, the positioning rod 19 contacts the positioning block 10. Due to the interaction force between the positioning rod 19 and the positioning groove on the positioning block 10, the connecting rod 12 is driven to move to the right, so that the left end of the connecting rod 12 rotates downward and moves to the right at the same time. At this time, the guide block 1611 moves to the right, the limiting block 17 is pressed, and the spring 18 is compressed again. At this time, the capturing clamp 13 is located at the bottom of the needle storage cylinder 3, near the middle. Releasing the pressing rod 4 causes the connecting rod 12 to move to the left due to the elastic force of spring 18 and the fixing rod 9. Simultaneously, the elastic force of spring 5, combined with the fixing rod 9, causes the connecting rod 12 to rotate upwards. This allows the capturing clamp 13 to rotate upwards and move to the left within the needle storage cylinder 3. Consequently, the capturing clamp 13 places one of the acupuncture needle cylinders 14 at the bottom of the needle storage cylinder 3, pressing the acupuncture needle cylinder 14 into the strip-shaped guide groove 8. Before the connecting rod rotates to the horizontal position... Before positioning, the capture clamp 13, in conjunction with the strip guide groove 8, squeezes and positions the acupuncture needle cylinder 14. When the connecting rod is subjected to the elastic force of the second spring 5 (i.e., the second spring 5 drives the first pressure rod 6, and the first pressure rod 6 drives the connecting rod to rotate upward), the capture clamp 13 at the left end of the connecting rod is subjected to the force of the acupuncture needle cylinder 14 to the right, thereby causing the guide block 11 at the right end of the connecting rod 12 to move to the right, the first spring 18 is compressed, and the capture clamp 13 continues to rotate upward, causing the acupuncture needle cylinder 14 to move upward along the strip groove 15 so that its upper end passes through the needle outlet hole 2, thereby popping out the acupuncture needle cylinder 14.(In the above structure, before the connecting rod 12 rotates to the horizontal position, the pressure rod 6, under the elastic force of the spring 5, can completely rotate the connecting rod to the horizontal position, or, as needed, limit the maximum upward movement distance of the pressure rod 7 to ensure that the connecting rod can only rotate upward to the horizontal position at the maximum angle. No specific technical restrictions are imposed on the specific technical solution. The specific elastic force of the spring 5 and the spring 18 can be set as needed, without further technical details, as long as the above functions can be achieved.) Furthermore, the friction between the capturing clamp 13 and the acupuncture needle cylinder 14 is much greater than the friction between the acupuncture needle cylinder 14 and the inner surface of the needle storage cylinder 3, so that the acupuncture needle cylinder 14 can move upward under the action of the capturing clamp 13. The material of the contact surface between the capturing clamp 13 and the acupuncture needle cylinder 14 can be selected as needed, without specific technical restrictions.
