Description

Technical Field

[0001] The invention relates to the technical field of infusion needles, and in particular to a pollutant collection and treatment device used for oncology nursing. Background Art

[0002] In the field of medical care, especially in oncology, the treatment of medical waste has always been an important and complex issue; especially syringes, injection needles, etc. If these pollutants are not properly handled, they may not only cause direct harm to medical staff and patients, but also spread diseases through various channels and cause long-term pollution to the environment; needles, as the core instruments for drug injection, play a vital role. Their design and use strictly follow medical standards to ensure that drugs can be delivered to patients accurately and effectively; the safety and hygiene of needles are important considerations in their design, because any slight contamination or improper operation may have a serious impact on the patient's health.

[0003] However, when dealing with discarded injection needles, traditional methods often present many challenges. Common injection needles are usually composed of a metal injection needle and a plastic needle holder. The physical and chemical properties of these two materials are significantly different, making their separation a technical challenge. Metal injection needles are hard and corrosion-resistant, while plastic needle holders are relatively soft and easy to process and shape. It is not easy to separate the two during processing, which is not conducive to resource separation and recycling.

[0004] Traditionally, in order to avoid the safety risks caused by the leakage of the sharp end of the needle, staff usually bend or coil the metal injection needle. Although this method reduces the threat posed by the needle to personnel and the environment to a certain extent, it does not fundamentally solve the technical difficulties in needle separation. Bending or coiling not only increases the complexity of processing, but may also cause the needle to break or fragments to scatter during the processing, thereby increasing processing costs and risks.

[0005] Therefore, in view of this, the inventor proposes a pollutant collection and treatment device for oncology care to solve the above technical problems. Summary of the invention

[0006] The purpose of the present invention is to provide a pollutant collection and treatment device for oncology nursing to solve the problem that traditional metal injection needles and plastic needle seats are difficult to separate and treat.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows: A pollutant collection and treatment device for oncology nursing, comprising: a box body, an upper seat body and a lower seat body fixedly arranged in the box body, a guide rod is arranged between the upper seat body and the lower seat body, and a push seat and a sliding seat are slidably connected to the guide rod; The lower seat body is provided with a driving structure, which is connected to the pushing seat and is used to drive the pushing seat to rise or fall along the length direction of the guide rod; An upward clamping assembly is provided between the upper seat body and the pushing seat, and when the pushing seat moves upward, the metal injection needle can be clamped and driven to move upward; A downward clamping assembly is provided between the sliding seat and the pushing seat, and when the pushing seat moves downward, the metal injection needle can be clamped and driven to move downward; A first elastic member is sleeved on the guide rod, the first elastic member is located between the sliding seat and the lower seat body, and the first elastic member has a tendency to drive the sliding seat to move upward; It also includes a clamp, which is arranged above the box body and is used to clamp or release the plastic needle seat.

[0008] According to the above technical solution, after the device is started, the medical staff first properly places the used syringe or needle in the device box, ensuring that the plastic needle seat part is accurately aligned with the preset position of the seat body. Then, the clamp is activated to tightly clamp the plastic needle seat to ensure that it will not move or fall off during subsequent processing.

[0009] Next, the driving structure starts to work, and through a series of precise mechanical transmissions, it drives the push seat to slowly rise along the guide rod. At the same time, the upward clamping assembly accurately clamps the metal injection needle at the preset position. As the push seat continues to rise, the upward clamping assembly firmly drives the metal injection needle to move upward together. In this process, the downward clamping assembly remains in a non-clamping state, so that the metal injection needle and the plastic needle seat are initially loosened, preparing for the subsequent complete separation. Subsequently, the driving structure changes the direction of movement and drives the push seat to slowly descend along the guide rod. In this process, the upward clamping assembly releases the clamping of the metal injection needle in a timely manner, while the downward clamping assembly quickly and accurately clamps the metal injection needle. As the push seat continues to descend, the downward clamping assembly firmly drives the metal injection needle to move further downward until it is completely separated from the plastic needle seat.

[0010] Further, the upward clamping assembly includes a first mounting seat, a second mounting seat and two first clamping blocks, the two first clamping blocks are arranged between the first mounting seat and the second mounting seat, and the two first clamping blocks are slidably mounted on the second mounting seat; When the first mounting seat and the second mounting seat are close to each other, the two first clamping blocks are close to each other and can clamp the metal injection needle; when the first mounting seat and the second mounting seat are far away from each other, the two first clamping blocks are far away from each other and the two first clamping blocks release the metal injection needle.

[0011] According to the above technical solution, the upward clamping assembly is composed of a first mounting seat, a second mounting seat and two first clamping blocks. The two first clamping blocks are mounted on the second mounting seat and can slide thereon. When the push seat rises, it drives the first mounting seat to approach the second mounting seat. As the distance between the two is shortened, the two first clamping blocks are squeezed and approach each other, thereby achieving accurate clamping of the metal injection needle. On the contrary, when the push seat descends, the distance between the first mounting seat and the second mounting seat increases, and the two first clamping blocks will move away from each other after losing the squeezing, thereby releasing the clamping of the metal injection needle. This design not only improves the accuracy and stability of clamping, but also ensures the safety during the clamping process. Through the mutual approach and distance between the first mounting seat and the second mounting seat, the reliable clamping and release of the metal injection needle are achieved, making the clamping process more flexible and smooth, and avoiding needle damage or personal injury caused by improper clamping.

[0012] Furthermore, two oblique rods are symmetrically fixedly arranged on the first mounting seat, and the two oblique rods are distributed in an "eight" shape; Each of the first clamping blocks is provided with an oblique groove corresponding to one of the oblique rods, and the oblique rod and the oblique groove are adapted to each other.

[0013] Furthermore, a placement groove is provided on the upper seat body, the top of the first mounting seat extends into the placement groove and can slide in the placement groove, and a plurality of second elastic members are arranged in the placement groove, and the second elastic members have a tendency to drive the first mounting seat to move downward.

[0014] According to the above technical solution, the placement groove design on the upper seat body and the second elastic member therein provide an ingenious mechanism for the initial loosening of the metal injection needle and the plastic needle seat. Specifically, when the first mounting seat moves upward under the action of the driving structure, the portion of its top extending into the placement groove also rises accordingly. Since a number of second elastic members are arranged in the placement groove, these elastic members always exert a downward force on the first mounting seat to keep it stable. However, when the first mounting seat is pushed up, it will overcome the elastic force of these elastic members and move up together with the metal injection needle. This upward movement process not only achieves the clamping of the metal injection needle, but more importantly, it causes the initial loosening between the metal injection needle and the plastic needle seat. This loosening lays the foundation for the subsequent complete separation of the metal injection needle and the plastic needle seat, making the connection between the two more fragile, so that it is easier to achieve complete separation in the subsequent separation step, improving the efficiency and accuracy of the separation of the metal injection needle and the plastic needle seat, and reducing the difficulties that may occur during the separation process. At the same time, it also reduces the risk of medical staff during operation, making the entire treatment process safer and more reliable.

[0015] Further, the downward clamping assembly comprises a third mounting seat and a fourth mounting seat, and two second clamping blocks are symmetrically arranged in the third mounting seat; When the third mounting seat and the fourth mounting seat are close to each other, the two second clamping blocks are close to each other to clamp the metal injection needle; When the third mounting seat and the fourth mounting seat move away from each other, the two second clamping blocks move away from each other, and the two second clamping blocks release the metal injection needle.

[0016] Further, the fourth mounting seat comprises a bottom plate fixed on the sliding seat, and two inclined wedge blocks are symmetrically arranged on the bottom plate; The third mounting seat comprises a top seat and two third elastic members, the two third elastic members are respectively mounted on the two second clamping blocks, and the two third elastic members have a tendency to drive the two second clamping blocks away from each other; the two second clamping blocks are both slidably connected in the top seat; The elastic force of the third elastic member is smaller than the elastic force of the first elastic member.

[0017] According to the above technical solution, when the driving structure drives the push seat to work downward, the push seat slowly descends along the guide rod, and the upward clamping assembly gradually loosens the clamping of the metal injection needle. At the same time, as the third mounting seat and the fourth mounting seat approach each other, the two second clamping blocks also gradually move toward the middle, firmly clamping the metal injection needle; then, as the push seat continues to descend, the downward clamping assembly firmly clamps the metal injection needle and moves downward together. During this process, the connection between the metal injection needle and the plastic needle seat gradually becomes fragile until it is finally completely detached.

[0018] Further, the driving structure includes a first connecting rod and a second connecting rod symmetrically arranged between the pushing seat and the lower seat body, the first connecting rod is hinged to the second connecting rod, the end of the first connecting rod is hinged to the pushing seat, and the end of the second connecting rod is hinged to the lower seat body; A pushing member is connected between the two second connecting rods; A first cylinder is eccentrically or centrally arranged on the lower seat body, and a piston end of the first cylinder penetrates the lower seat body and is connected with the pushing member.

[0019] According to the above technical solution, the first connecting rod and the second connecting rod are symmetrically arranged between the push seat and the lower seat body, and are connected by a hinged manner to form a movable parallelogram structure. The end of the first connecting rod is hinged to the push seat, and the end of the second connecting rod is hinged to the lower seat body. This design allows the push seat to remain stable when moving up and down. Between the two second connecting rods, there is a pusher connected, which plays a role in transmitting power. A first cylinder is eccentrically or centrally installed on the lower seat body, and its piston end passes through the lower seat body and is connected to the pusher. When the first cylinder is started, its piston end will push the pusher, thereby driving the two second connecting rods and the first connecting rod connected thereto to move. Due to the hinged relationship between the connecting rods, this movement will be converted into the up and down movement of the push seat, and the driving structure can accurately control the lifting and lowering of the push seat, thereby realizing fine regulation of the separation process of the metal injection needle and the plastic needle seat.

[0020] Furthermore, piston parts are formed at both ends of the pusher; Cylinder bodies are symmetrically arranged on both sides of the lower seat body, and each of the piston parts is sealingly and slidably connected in one of the cylinder bodies, and the cylinder body is divided into a first air cavity and a second air cavity. A sealing telescopic plate is arranged on the cylinder body, and the sealing telescopic plate is installed on the cylinder body to seal the second air cavity; The cylinder body is provided with an air inlet and an air outlet connected with the second air cavity. The air inlet and the air outlet are both provided with a one-way valve film, and the air outlet is connected with an air pipe. When the pusher rises, the pusher will drive the two piston parts to rise synchronously. During the rising process of the two piston parts, the volume of the second air cavity increases, and the air flow enters the second air cavity. When the pusher moves downward, the volume of the second air cavity decreases, and the air flow in the second air cavity enters the blowing air channel through the air pipe, and finally blows out from the blowing hole. Since the metal injection needle has been separated from the plastic needle seat at this time, the blowing hole is located at the bottom of the needle seat groove, and the air flow blows the plastic needle seat out of the needle seat groove, which is convenient for the next use. Furthermore, a needle seat groove for accommodating the plastic needle seat is provided on the upper seat body, and a heating tube is provided in the needle seat groove, and the heating tube is used to soften the plastic needle seat; An air blowing hole and an air blowing flow channel are provided at the bottom of the needle seat groove. The air blowing hole is communicated with the air blowing flow channel, and the air blowing flow channel is communicated with the air pipe.

[0021] According to the above technical solution, when the pusher rises, it synchronously drives the two piston parts to slide upward in the cylinder body. As the piston part rises, the volume of the second air chamber gradually increases, forming a negative pressure, thereby allowing the external airflow to enter the second air chamber through the one-way valve membrane at the air inlet; when the pusher moves downward, the piston part also slides down in the cylinder body. This action causes the volume of the second air chamber to decrease rapidly and the internal air pressure to increase. Since a one-way valve membrane is also provided at the air outlet, and the air outlet is connected to the blowing air channel through an air pipe, the high-pressure airflow is forced to enter the blowing air channel through the air pipe. The airflow reaches the end of the blowing air channel and is blown out from the blowing hole provided at the bottom of the needle seat groove. It is worth noting that at this time, the metal injection needle has completed its injection task and is separated from the plastic needle seat. Therefore, the airflow blown out from the blowing hole can directly act on the plastic needle seat and blow it out of the needle seat groove. This design not only simplifies the replacement process of the plastic needle seat, but also greatly improves the use efficiency and convenience of the device.

[0022] Furthermore, an electromagnetic heat pipe is provided in the pushing seat and / or the upward clamping assembly, and the electromagnetic heat pipe is used to sterilize the metal injection needle at high temperature; The clamp comprises two second cylinders, which are symmetrically arranged on the top of the box body, and the two second cylinders are used to clamp or release the plastic needle seat.

[0023] According to the above technical solution, the push seat or the upward clamping assembly is embedded with an electromagnetic heat pipe. When the device is started, the electromagnetic heat pipe heats up rapidly to sterilize the metal injection needle passing through it at high temperature to ensure the safety of medical use. At the same time, the clamp part is composed of two second cylinders symmetrically arranged on the top of the box body. They work together to fix the plastic needle seat through precise clamping action to ensure the stability of the injection process.

[0024] Beneficial effects of the present invention: 1. The device of the present application realizes efficient and safe separation of metal injection needles and plastic needle seats through precise mechanical transmission and clamping component design; the coordinated work of the upward clamping component and the downward clamping component ensures the stability and accuracy of the needle during the separation process, avoids needle damage or personal injury caused by improper operation, and greatly improves the separation efficiency and safety.

[0025] 2. The driving structure in the device of the present application is not only responsible for driving the lifting and lowering of the clamping assembly, but also realizes the blowing function of the plastic needle seat through the clever air path design. This multi-purpose design simplifies the operation process, improves the efficiency of the equipment, and also reduces the manufacturing cost. In addition, the plastic needle seat is softened by the heating tube, which further ensures the smooth progress of the separation process.

[0026] 3. The electromagnetic heat pipe installed in the device of this application can sterilize the metal injection needle at high temperature, effectively kill bacteria and viruses on the surface of the needle, and reduce the risk of cross infection. This function can ensure the safety of medical staff and patients in high-risk environments such as oncology care. At the same time, high-temperature sterilization also extends the service life of the needle, reduces the generation of medical waste, and is beneficial to environmental protection.

DETAILED DESCRIPTION

[0030] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0032] This embodiment proposes a pollutant collection and treatment device for oncology nursing, such as Figures 1 to 13As shown, it includes a box body 1, an upper seat body 2 and a lower seat body 3 fixedly arranged in the box body 1, the upper seat body 2 is arranged above the lower seat body 3, a guide rod 4 is arranged between the upper seat body 2 and the lower seat body 3, the number of the guide rods 4 is four, and a pushing seat 5 and a sliding seat 6 are slidably connected to the guide rod 4, and the pushing seat 5 is located above the sliding seat 6.

[0033] A driving structure 11 is provided on the lower seat body 3, and the driving structure 11 passes through the sliding seat 6 and is connected to the pushing seat 5. The driving structure 11 is used to drive the pushing seat 5 to rise or fall along the length direction of the guide rod 4; an upward clamping assembly 7 is provided between the upper seat body 2 and the pushing seat 5. When the pushing seat 5 moves upward, the upward clamping assembly 7 can clamp the metal injection needle 92 and drive the metal injection needle 92 to move upward.

[0034] A downward clamping assembly 8 is provided between the sliding seat 6 and the pushing seat 5 . When the pushing seat 5 moves downward, the metal injection needle 92 can be clamped and driven to move downward.

[0035] A first elastic member 41 is sleeved on the guide rod 4 . The first elastic member 41 is located between the sliding seat 6 and the lower seat body 3 . The first elastic member 41 has a tendency to drive the sliding seat 6 away from the lower seat body 3 .

[0036] It also includes a clamp 10 , which is arranged above the box body 1 , wherein the clamp 10 includes two second cylinders 101 , which are symmetrically arranged on the top of the box body 1 , and the two second cylinders 101 are used to clamp or release the plastic needle seat 91 .

[0037] According to the above technical solution, the medical staff first properly places the used injection needle in the equipment box 1, ensuring that the plastic needle seat 91 is precisely placed at the preset position of the upper seat body 2. Then, the clamp 10 is started to tightly clamp the plastic needle seat 91 to ensure that it will not move or fall off during the subsequent processing; next, the driving structure 11 starts to work, driving the push seat 5 to slowly rise along the length direction of the guide rod 4. At the same time, the upward clamping assembly 7 precisely clamps the metal injection needle 92 at the preset position. As the push seat 5 continues to rise, the upward clamping assembly 7 firmly drives the metal injection needle 92 to move upward together, so that the metal injection needle 92 and the plastic needle seat 91 are initially loosened, preparing for the subsequent complete separation. In this process, the downward clamping assembly 8 remains in a non-clamping state. Subsequently, the driving structure 11 changes the direction of movement, driving the push seat 5 to slowly descend along the length direction of the guide rod 4. During this process, the upward clamping assembly 7 gradually releases the clamping of the metal injection needle 92, while the downward clamping assembly 8 gradually clamps the metal injection needle 92. As the push seat 5 continues to descend, the downward clamping assembly 8 firmly drives the metal injection needle 92 to move further downward until it is completely separated from the plastic needle seat 91, thereby realizing the separation of the metal injection needle 92 and the plastic needle seat 91.

[0038] As a preferred embodiment, Figure 1 , Figure 2 and Fig.10 As shown, the upward clamping assembly 7 includes a first mounting seat 71, a second mounting seat 72 and two first clamping blocks 73, the two first clamping blocks 73 are arranged between the first mounting seat 71 and the second mounting seat 72, and the two first clamping blocks 73 are slidably mounted on the second mounting seat 72; two oblique rods 711 are symmetrically fixedly arranged on the first mounting seat 71, and the two oblique rods 711 are distributed in an "eight" shape; each first clamping block 73 is provided with an oblique groove 731 corresponding to one of the oblique rods 711, and the oblique rods 711 and the oblique grooves 731 are adapted to each other.

[0039] When the first mounting seat 71 and the second mounting seat 72 are close to each other, the two first clamping blocks 73 are close to each other and can clamp the metal injection needle 92; when the first mounting seat 71 and the second mounting seat 72 are away from each other, the two first clamping blocks 73 are away from each other and the two first clamping blocks 73 release the metal injection needle 92.

[0040] According to the above technical solution, the two first clamping blocks 73 are installed on the second mounting seat 72 and can slide thereon; when the push seat 5 rises, it drives the second mounting seat 72 to approach the first mounting seat 71. As the distance between the two is shortened, under the action of the two oblique rods 711, the two first clamping blocks 73 are guided by the oblique rods 711 and approach each other, thereby clamping the metal injection needle 92 between the two first clamping blocks 73. On the contrary, when the push seat 5 descends, it drives the second mounting seat 72 away from the first mounting seat 71, the distance between the second mounting seat 72 and the first mounting seat 71 increases, and the two first clamping blocks 73 are guided by the oblique rods 711 and move away from each other, thereby gradually releasing the clamping of the metal injection needle 92. Through the mutual approach and distance between the first mounting seat 71 and the second mounting seat 72, the reliable clamping and release of the metal injection needle 92 is achieved, making the clamping process more flexible and smooth, and avoiding needle damage or personal injury caused by improper clamping.

[0041] As a preferred embodiment, Fig.10 As shown, a placement groove 21 is provided on the upper seat body 2, and the top of the first mounting seat 71 extends into the placement groove 21 and can slide in the placement groove 21. A plurality of second elastic members 22 are arranged in the placement groove 21, and the second elastic members 22 have a tendency to drive the first mounting seat 71 to move downward.

[0042] According to the above technical solution, the design of the placement groove 21 on the upper seat body 2 and the second elastic member 22 therein provide an ingenious mechanism for the initial loosening of the metal injection needle 92 and the plastic needle seat 91. Specifically, when the first mounting seat 71 moves upward under the action of the driving structure 11, the top portion thereof extending into the placement groove 21 also rises accordingly. Since a plurality of second elastic members 22 are arranged in the placement groove 21, these elastic members always exert a downward force on the first mounting seat 71 to keep it stable. However, when the first mounting seat 71 is pushed upward, it will overcome the elastic force of these elastic members and move upward together with the metal injection needle 92. This upward movement process not only realizes the clamping of the metal injection needle 92, but more importantly, since the plastic needle seat 91 is fixed by the clamp 10, the metal injection needle 92 is clamped by the upward clamping assembly 7 and driven to move upward at the same time, so that the metal injection needle 92 and the plastic needle seat 91 are initially loosened. This looseness lays the foundation for the subsequent complete separation of the metal injection needle 92 and the plastic needle holder 91, making the connection between the two more fragile, making it easier to achieve complete separation in the subsequent separation step, improving the efficiency and accuracy of the separation of the metal injection needle 92 and the plastic needle holder 91, and reducing the difficulties that may occur during the separation process. At the same time, it also reduces the risk of medical staff during operation, making the entire treatment process safer and more reliable.

[0043] As a preferred embodiment, Figure 1 , Fig. 9 and Fig.11 As shown, the downward clamping assembly 8 includes a third mounting seat 81 and a fourth mounting seat 82, and two second clamping blocks 83 are symmetrically arranged in the third mounting seat 81; when the third mounting seat 81 and the fourth mounting seat 82 are close to each other, the two second clamping blocks 83 are close to each other and are used to clamp the metal injection needle 92; when the third mounting seat 81 and the fourth mounting seat 82 are away from each other, the two second clamping blocks 83 are away from each other, and the two second clamping blocks 83 release the metal injection needle 92.

[0044] The fourth mounting seat 82 includes a bottom plate 821 fixed on the sliding seat 6, and two inclined wedge blocks are symmetrically fixed on the bottom plate 821; the third mounting seat 81 includes a top seat 811 and two third elastic members 812, the elastic force of the third elastic member 812 is smaller than the elastic force of the first elastic member 41, and the two third elastic members 812 are respectively installed on the two second clamping blocks 83, and the two third elastic members 812 have a tendency to drive the two second clamping blocks 83 away from each other; the two second clamping blocks 83 are both slidably connected in the top seat 811.

[0045] According to the above technical solution, when the driving structure 11 drives the pushing seat 5 to work downward, the pushing seat 5 slowly descends along the guide rod 4, and the upward clamping assembly 7 gradually loosens the clamping of the metal injection needle 92. At the same time, as the third mounting seat 81 and the fourth mounting seat 82 approach each other, the two second clamping blocks 83 contact with the corresponding inclined wedge blocks, and the two second clamping blocks 83 also gradually move toward the middle to firmly clamp the metal injection needle 92; then, as the pushing seat 5 continues to descend, the downward clamping assembly 8 firmly clamps the metal injection needle 92 and moves downward together. During this process, the connection between the metal injection needle 92 and the plastic needle seat 91 gradually becomes fragile until it is finally completely detached.

[0046] As a preferred embodiment, Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the driving structure 11 includes a first connecting rod 111 and a second connecting rod 112 symmetrically arranged between the push seat 5 and the lower seat body 3, the first connecting rod 111 and the second connecting rod 112 are hinged, the end of the first connecting rod 111 is hinged to the push seat 5, and the end of the second connecting rod 112 is hinged to the lower seat body 3; a pusher 113 is connected between the two second connecting rods 112; a first cylinder 31 is eccentrically or centrally arranged on the lower seat body 3, and the piston end of the first cylinder 31 penetrates the lower seat body 3 and is connected to the pusher 113. When the first cylinder 31 is eccentrically installed on the lower seat body 3, a hole corresponding to the metal injection needle 92 can be opened on the lower seat body 3 to facilitate the discharge of the metal injection needle 92; of course, the first cylinder 31 can also be installed at the center of the lower seat body 3, and an air pump (not shown) can be installed inside the box body 1 to blow the metal injection needle 92 out from the side.

[0047] According to the above technical solution, the first connecting rod 111 and the second connecting rod 112 are symmetrically arranged between the pushing seat 5 and the lower seat body 3, and are connected by a hinge to form a movable parallelogram structure. The end of the first connecting rod 111 is hinged to the pushing seat 5, and the end of the second connecting rod 112 is hinged to the lower seat body 3. This design enables the pushing seat 5 to remain stable when moving up and down.

[0048] When the first cylinder 31 is started, its piston end will push the pusher 113, thereby driving the two second connecting rods 112 and the first connecting rod 111 connected thereto to move. Due to the hinged relationship between the connecting rods, this movement will be converted into the up and down movement of the push seat 5. The driving structure 11 can accurately control the lifting and lowering of the push seat 5, thereby achieving fine regulation of the separation process of the metal injection needle 92 and the plastic needle seat 91.

[0049] As a preferred embodiment, Figure 5 , Figure 7 and Figure 8 As shown, piston parts 114 are formed at both ends of the pusher 113; cylinder bodies 32 are symmetrically arranged on both sides of the lower seat body 3, and each piston part 114 is sealingly and slidably connected in one of the corresponding cylinder bodies 32, and the cylinder body 32 is divided into a first air cavity and a second air cavity 321. A sealing telescopic plate 33 is arranged on the cylinder body 32, and the sealing telescopic plate 33 is installed on the cylinder body 32 to seal the second air cavity 321. The sealing telescopic plate 33 can be an elastic rubber plate that can be telescopic, and its function is to seal the second air cavity 321; As a preferred embodiment, Fig.12As shown, the upper seat body 2 is provided with a needle seat groove 23 for accommodating the plastic needle seat 91, and a heating tube 12 is arranged in the needle seat groove 23, and the heating tube 12 is used to soften the plastic needle seat 91; the bottom of the needle seat groove 23 is provided with a blowing hole 211 and a blowing flow channel 212, and the blowing hole 211 is connected with the blowing flow channel 212, and the blowing flow channel 212 is connected with the air pipe 325. The cylinder body 32 is provided with an air inlet 322 and an air outlet 323 connected with the second air cavity 321, and a one-way valve film 324 is arranged at the air inlet 322 and the air outlet 323, and the air outlet 323 is connected with the air pipe 325. When the pusher 113 rises, the two pistons 114 are synchronously driven to slide upward in the cylinder body 32. As the pistons 114 rise, the volume of the second air chamber 321 gradually increases, forming a negative pressure, thereby allowing external air to enter the second air chamber 321 through the one-way valve film 324 at the air inlet 322; when the pusher 113 moves downward, the piston 114 also slides down in the cylinder body 32. This action causes the volume of the second air chamber 321 to decrease rapidly, and the internal air pressure increases. Since the one-way valve film 324 is also provided at the air outlet 323, and the air outlet 323 is connected to the air blowing channel 212 through the air pipe 325, the air outlet 323 is connected to the air blowing channel 212 through the air pipe 325. The airflow reaches the end of the blowing channel 212 and is blown out from the blowing hole 211 provided at the bottom of the needle seat groove 23. It is worth noting that at this time, the metal injection needle 92 has completed its injection task and is separated from the plastic needle seat 91. Therefore, the airflow blown out from the blowing hole 211 can directly act on the plastic needle seat 91 and blow it out of the needle seat groove 23. This design not only simplifies the replacement process of the plastic needle seat 91, but also greatly improves the use efficiency and convenience of the device, that is, one power source (the first cylinder 31) realizes multiple functions.

[0050] As a preferred embodiment, an electromagnetic heat pipe 13 is provided in the pushing seat 5 and / or the upward clamping assembly 7, and the electromagnetic heat pipe 13 can generate high temperature for high-temperature sterilization of the metal injection needle 92; in this embodiment, the electromagnetic heat pipe 13 is provided in both the pushing seat 5 and the upward clamping assembly 7; it should be noted that the electromagnetic heat pipe 13 adopts the electronic heating components in the prior art.

[0051] The specific implementation method of the present application is as follows: First, the medical staff properly places the used injection needle in the equipment box 1, ensuring that the plastic needle seat 91 is precisely placed in the preset position of the upper seat 2, that is, in the needle seat groove 23. At this time, the heating tube 12 in the needle seat groove 23 starts to work, softening the plastic needle seat 91 to prepare for the subsequent separation step. Next, the clamp 10 is started, and the two second cylinders 101 are symmetrically arranged on the top of the box 1, tightly clamping the plastic needle seat 91 to ensure that it will not move or fall off during the subsequent processing. This step is the key to ensure the smooth progress of the separation process. Then, the drive structure 11 starts to work. The first cylinder 31 is started, and its piston end pushes the pusher 113, thereby driving the two second connecting rods 112 and the first connecting rod 111 connected thereto to move. Due to the hinged relationship between the connecting rods, this movement will be converted into the up and down movement of the push seat 5. When the push seat 5 rises, it drives the upward clamping assembly 7 to slowly rise along the length direction of the guide rod 4. During this process, the first mounting seat 71 and the second mounting seat 72 approach each other, and the two first clamping blocks 73 approach each other under the guidance of the oblique rod 711, tightly clamping the metal injection needle 92. As the push seat 5 continues to rise, initial looseness occurs between the metal injection needle 92 and the plastic needle seat 91.

[0052] Subsequently, the clamp 10 releases the plastic needle seat 91, and the driving structure 11 changes the direction of movement, driving the push seat 5 to slowly descend along the length direction of the guide rod 4. In this process, the upward clamping assembly 7 gradually releases the clamping of the metal injection needle 92, and the downward clamping assembly 8 works synchronously, the third mounting seat 81 and the fourth mounting seat 82 approach each other, and the two second clamping blocks 83 also approach each other under the action of the inclined wedge block, firmly clamping the metal injection needle 92. As the push seat 5 continues to descend, the downward clamping assembly 8 firmly drives the metal injection needle 92 to move further downward until it is completely separated from the plastic needle seat 91.
