Description

Technical Field

[0001] The present invention relates to the technical field of sharps containing technology, and in particular to a sharps containing device that automatically processes sharps. Background Art

[0002] Sharps barrels are often used in hospitals as storage tools for sharps such as syringe needles, infusion tube needles, small glass products, blades, suture needles, etc. However, most existing sharps barrels are manual instruments. When storing sharps, medical staff need to manually operate the sharps barrels, which makes it very easy for medical staff to be cut by sharps. And when cutting sharps, manual cutting is also required, which further increases the burden on medical staff. In the prior art, a one-size-fits-all approach is usually adopted for the accommodation of multiple sharps. Medical staff manually cut sharps of different sizes and lengths and then collect them. This greatly increases the workload of medical staff, and thicker sharps are not easy to be cut. Even if the cutting is completed, the residual waste liquid that may exist in them will cause pollution. The present invention uses priority design to process the sharps in a corresponding manner under multiple priorities, so that the device can be used for a variety of sharps, which is particularly conducive to the comprehensive use of medical staff. The variability of the treatment site determines that the sharps container needs to handle different medical sharps in different occasions. In particular, placing a large number of different medical sharp instruments in the same container, handling different sharp instruments and making full use of the container space are very important technical measures.

[0003] Chinese patent CN108888840B discloses a medical sharps box device, including a sharps box and a support bracket; the sharps box includes an upper box body for storing needles and a lower box body for storing syringes, the upper box body is an inverted cone structure, the upper box body has a hollow inner cavity, a cylindrical sleeve is arranged in the inner cavity of the upper box body, the upper and lower ports of the cylindrical sleeve are respectively arranged on the upper and lower end surfaces of the upper box body, a storage cavity for storing needles is formed between the outer circumferential surface of the cylindrical sleeve and the inner side surface of the upper box body, and a needle delivery port is arranged on the upper end surface of the upper box body; a lower box body is arranged below the upper box body, the lower end of the upper box body extends into the upper port of the lower box body, the lower box body is a hollow columnar structure with an open upper end, and an annular retaining edge is arranged on the edge of the upper port of the lower box body; the support bracket is used to support the sharps box. The sharps box in the patent can be easily moved, and during use, discarded needles and syringes can be placed and collected separately, which can effectively improve the safety of clinical operations. However, the defect of this patent is that the sharp objects are not cut, so that the sharp objects entering therein may have a longer needle end and pierce the device, thereby causing harm to medical personnel during the cleaning process or use.

[0004] Chinese patent CN109592259B discloses a sealing mechanism for a sharps box for general medical use, including a barrel, a barrel cover, a No. 1 sealing rotating plate, a No. 2 sealing rotating plate, and an inner lining plate. The barrel top is provided with a barrel cover, the upper end is provided with a No. 1 sealing rotating plate, the lower end of the barrel cover is provided with a No. 2 sealing rotating plate, the lower end of the No. 2 sealing rotating plate is provided with an inner lining plate, the edges of the inner lining plate are fixedly connected to the inner side of the upper end of the barrel, the inner lining plate and the barrel cover are fixedly connected with a limited block, one end of the limited block is fixedly connected to the inner side of the barrel, one side of the limited block is fixedly connected with multiple groups of clamping blocks, and the inner lining plate is provided with corresponding clamping grooves corresponding to the clamping blocks. This patent has the advantages of simple structure, convenient use, good sealing effect, and sharps are not easy to fall out after sealing. It is mainly used for sealing and processing of medical sharps. However, the defect of this patent is that although multiple sealing plates are used to seal the opening of the sharp tool bucket, the process still needs to be performed by medical personnel, and it is still impossible to avoid cutting the hands of medical personnel. There is also no cutting device, so the practical value of this patent is relatively low.

[0005] Chinese patent CN109663179B discloses a medical intelligent sharps box, comprising a cylinder for holding medical sharps; a cover, the cover is arranged on the upper end of the cylinder, and a first opening is arranged on the cover; a disc, the disc is rotatably arranged on the cover, the disc is coaxial with the cover, a second opening corresponding to the first opening is opened on the disc, and a card is arranged on the disc and on one side of the second opening; a smart cover is detachably arranged on the cover, which automatically opens when medical staff need to throw the sharp into the cylinder and automatically closes after throwing. When medical staff throw the sharp into the sharp box, there is no need to manually rotate the disc to open the opening, so as to avoid the sharp stabbing the medical staff, and improve the safety performance. At the same time, after the medical staff throws the sharp into the sharp box, there is no need to manually rotate the disc to close the opening, which complies with the hospital infection prevention regulations, and it is not easy to make the sharp in the sharp box fall out, which is beneficial to environmental protection. Although the patent uses a smart cover to control the opening and closing, it only uses this method, which makes it impossible to take different treatment measures according to the different types of sharp objects inserted by medical staff. For example, if a long syringe is stuck at the opening and the medical staff leaves the top of the smart cover, the device may be damaged due to failure to close, and there is a lack of heating plate to plastic seal the syringe and a lack of cutting plate for cutting.

[0006] In addition, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the inventor studied a large number of documents and patents when making the present invention, but due to space limitations, not all details and contents are listed in detail. However, this does not mean that the present invention does not have the characteristics of these prior arts. On the contrary, the present invention already has all the characteristics of the prior art, and the applicant reserves the right to add relevant prior art to the background technology. Summary of the invention

[0007] In view of the shortcomings of the prior art, the technical solution of the present invention is to provide an automatic sharp handling storage device, the device comprising: a storage cover for automatic cutting; an opening for placing sharp objects and sequentially passing through the first chamber, the second chamber and the third chamber into the storage body is provided at the axis of the storage cover, and the storage cover is provided with the first chamber, the second chamber and the third chamber. A first sensor for monitoring the actions of medical personnel is provided on the vertically outer side of the storage cover, the first sensor is of the first priority, when it detects that the medical personnel are approaching, the control terminal controls the motor in the first chamber to open the storage cover and controls the cylinder in the second chamber to preheat, the storage cover is also provided with a second sensor for monitoring the size and needle end of the sharp object in the opening, the second sensor is of the second priority, when it detects that the sharp object enters the opening, the control terminal controls the cylinder in the second chamber to clamp and controls the lifting part in the third chamber to align with the needle end of the sharp object, when the first sensor and the second sensor send signals at the same time, the control terminal uses the second priority as the control instruction to establish the action mode of the storage cover. When the first sensor detects that the medical staff's hand is placed above the receiving cover, it sends a signal to the control terminal, and the control terminal controls the motor to rotate, thereby opening the opening, allowing the medical staff to put the sharp weapon into the receiving cover. The medical staff does not need to manually open the opening of the sharp weapon receiving device, which avoids the problem of the medical staff's hands being cut by the sharp weapon that may be exposed or remain after cutting, causing infection, and improves the safety performance of the sharp weapon receiving device. After the sharp weapon is put in, there is no need to manually close the opening of the sharp weapon receiving device, which further prevents the occurrence of cuts, and ensures that the cut waste in the sharp weapon receiving device will not fall out of the opening.

[0008] According to a preferred embodiment, when the first sensor detects that the medical staff is away, the control terminal controls the motor to close the containing cover, and when the second sensor detects that there is a sharp weapon in the opening, the control terminal controls the motor to keep the containing cover normally open. The motor performs different working modes based on the different priorities of the instructions received. When containing sharp weapons, at least the working mode can be selected according to the size of the placed sharp weapon, including clamping the sharp weapon or directly placing the sharp weapon into the containing body or keeping the opening open or directly closing the opening. The multi-priority control method enables the device to be used for containing a variety of sharp weapons, which is particularly beneficial for the medical staff to use it in all aspects. The variability of the treatment site determines that the sharp weapon containing device needs to handle different medical sharp weapons in different occasions. In particular, it is a very important technical measure to put a large number of different medical sharp weapons into the same containing device, handle different sharp weapons and make full use of the containing space.

[0009] According to a preferred embodiment, the first chamber of the containing cover is provided with a rotating partition for closing the opening, the rotating axis of the rotating partition is not at the axis of the containing cover and can close the opening when rotating around it, the rotation of the rotating partition is controlled by a first sensor and a motor, when medical personnel need to put a sharp object into the containing cover, the first sensor monitors the medical personnel's actions and controls the working state of the motor, rotating the rotating partition to open the opening, and the second chamber is provided with a friction block and a cylinder for pushing or pulling back the friction block.

[0010] According to a preferred embodiment, the friction block is fixedly connected to the pushing end of the cylinder, and at least two friction blocks and two cylinders push the two friction blocks toward the axis of the containing cover in opposite directions on the same straight line. The two cylinders are opened and closed at the same time, and their telescopic states and distances are the same. The two friction blocks are tightly fitted and clamped with the sharp tool to increase the friction force on it, so that during the cutting process, the upper part of the sharp tool will not splash outward due to the torsional force. The friction block is provided with "fish scale"-like patterns, that is, upward arrow-shaped patterns are formed to limit the upward movement of the sharp tool.

[0011] According to a preferred embodiment, the second chamber is provided with a rectangular groove for accommodating the friction block and the cylinder, the two cylinders are respectively arranged on two opposite sides of the rectangular groove, and the midpoint of the rectangular groove is passed through by the opening.

[0012] According to a preferred embodiment, the third chamber is provided with a first cutting knife, a second cutting knife and two heating plates, the first cutting knife and the second cutting knife are arranged opposite to each other, the two heating plates are arranged opposite to each other, and the first cutting knife, the second cutting knife and the two heating plates are located on the same horizontal plane.

[0013] According to a preferred embodiment, a lifting platform is provided vertically in the third chamber for driving the first cutting knife, the second cutting knife and the two heating plates to move vertically, and the lifting platform moves to the corresponding position of the needle end based on the size of the sharp object monitored by the second sensor, and the first cutting knife, the second cutting knife and the two heating plates are all provided with a pushing element, and the first cutting knife, the second cutting knife and the two heating plates are provided with a first working mode and a second working mode, and the first working mode and the second working mode are switched based on the choice of the medical staff and / or the size of the sharp object monitored by the second sensor. The first working mode refers to pushing the first cutting knife and the second cutting knife to directly cut the sharp object. The second working mode refers to pushing the two heating plates close to the sharp object for heating and plastic sealing, and then pushing the first cutting knife and the second cutting knife to cut the sharp object after completion.

[0014] According to a preferred embodiment, when the first sensor detects that medical personnel are approaching, it also controls the heating plate in the third chamber to preheat; when the second sensor detects that the sharp weapon is small in size and has no tube body, it controls the heating plate in the third chamber to stop preheating and enter the first working mode.

[0015] According to a preferred embodiment, the first cutting knife is set as a flat blade, and the second cutting knife is set as a cross-shaped blade groove. The blade of the first cutting knife corresponds to the blade groove of the second cutting knife so that when the pushing element pushes the first cutting knife and the second cutting knife, the first cutting knife can fit with the second cutting knife. The sharp tool is affected by the three squeezing points of the first cutting knife and the second cutting knife, and the sharp tool can be easily cut off. This cutting method is more labor-saving than traditional scissors, and the cross-shaped square groove design of the second cutting knife prevents the cut needle from splashing and causing accidental injury to medical staff.

[0016] According to a preferred embodiment, the outer edge of the open end of the container body is provided with an external thread, the container cover is provided with an internal thread portion matched with the external thread, the radius of the container cover is the same as that of the container body, and the inner diameter of the internal thread is the same as the outer diameter of the container body. The container body and the container cover are tightly locked by threads to seal the two, thereby preventing sharp objects from being exposed therefrom, and preventing the ultraviolet sterilization lamp from irradiating the outside of the container body, and preventing the sprayed disinfectant liquid from penetrating out.

[0017] Beneficial technical effects of the present invention:

[0018] (1) The present invention uses priority design to process sharp objects in multiple priority levels, so that the device can be used to accommodate a variety of sharp objects, which is particularly beneficial for medical personnel to use it in all aspects. The variability of treatment sites determines that the sharp object container needs to handle different medical sharp objects in different occasions. In particular, it is a very important technical measure to put a large number of different medical sharp objects into the same container, handle different sharp objects and make full use of the storage space.

[0019] (2) The present invention, through the provision of the first sensor and the motor, enables medical personnel to place the sharps into the containing cover without having to manually open the opening of the sharps containing device, thereby avoiding the problem of the sharps being exposed or remaining after cutting and cutting the hands of the medical personnel, thereby improving the safety performance of the sharps containing device. After the sharps are placed, there is no need to manually close the opening of the sharps containing device, thereby further preventing the occurrence of cuts, and ensuring that the cut waste in the sharps containing device will not fall out of the opening.

[0020] (3) In the present invention, when the medical staff puts in the sharp object, the first sensor, the control terminal and the motor provide the medical staff with the closure and closing of the opening, and at the same time, the internal components that monitor the medical staff's hand behavior need to be preheated. Since the time period required for placing the sharp object and then processing it is very short, if it cannot be processed in a fast manner but waits for the sharp object to enter the sharp object storage device and then starts it separately in series, it is difficult to process the sharp object more efficiently. In the present invention, the cylinder is preheated so that the cylinder does not work in response to sudden instructions, and sudden start-up causes irreversible damage to the cylinder. Preheating means that the cylinder runs slowly, so that the various components of the cylinder are fully active, the wear of the cylinder is reduced, and the instantaneous start of the cylinder is prevented from wearing out the device, resulting in loss of sealing and power. After preheating, the cylinder can respond to the signal sent by the second sensor more quickly, quickly clamp the sharp object, and prevent the cylinder from not clamping in time due to the medical staff throwing it into the sharp object storage device too quickly.

[0021] (4) The two friction blocks are tightly fitted and clamped with the sharp tool to increase the friction force on it, so that during the cutting process, the upper part of the sharp tool will not splash outward due to the torsional force. The friction pattern is set to be "fish scale" shaped, that is, forming an upward arrow-shaped pattern to limit the upward movement of the sharp tool.

[0022] (5) The flat blade of the first cutting knife and the cross-shaped groove of the second cutting knife make the sharp object be affected by three squeezing points, so that the sharp object can be easily cut off. This cutting method is more labor-saving than traditional scissors, and the cross-shaped square groove design of the second cutting knife prevents the cut needle from splashing and causing accidental injury to medical personnel.

[0027] The following is a detailed description with reference to the accompanying drawings.

[0028] Example 1

[0029] The present application relates to an automatic sharp object handling and storage device, the device comprising: a storage cover 1 for automatic cutting. The storage cover 1 is provided with an opening for placing sharp objects and sequentially passing through the first chamber 3, the second chamber 4 and the third chamber 5 to enter the storage body 2 at the axis center, and the storage cover 1 is provided with the first chamber 3, the second chamber 4 and the third chamber 5. A first sensor for monitoring the actions of medical personnel is provided on the vertically outer side of the storage cover 1. The first sensor is of the first priority. When it detects that the medical personnel are approaching, the control terminal controls the motor 301 in the first chamber 3 to open the storage cover 1 and controls the cylinder 401 in the second chamber 4 to preheat. The storage cover 1 is also provided with a second sensor for monitoring the size and needle end of the sharp object in the opening. The second sensor is of the second priority. When it detects that the sharp object enters the opening, the control terminal controls the cylinder 401 in the second chamber 4 to clamp and controls the lifting part in the third chamber 5 to align with the needle end of the sharp object. When the first sensor and the second sensor send signals at the same time, the control terminal uses the second priority as the control instruction to establish the action mode of the storage cover 1. Preferably, the first sensor may be an infrared sensor. When the first sensor detects that the medical staff's hand is placed above the receiving cover 1, a signal is sent to the control terminal, and the control terminal controls the motor 301 to rotate, thereby opening the opening, so that the medical staff can put the sharp object into the receiving cover 1. The medical staff does not need to manually open the opening of the sharp object receiving device, which can avoid the problem of cutting the hands of the medical staff by the sharp objects that may be exposed or remain after cutting, leading to infection, thereby improving the safety performance of the sharp object receiving device. After the sharp object is put in, there is no need to manually close the opening of the sharp object receiving device, which further prevents the occurrence of cuts, so that the cut waste in the sharp object receiving device will not fall out of the opening.

[0030] The control terminal may be one or more of a computer, a portable mobile terminal, and a smart device. The portable mobile terminal may be, for example, one or more of a portable computer, a smart watch, smart glasses, a smart bracelet, and a tablet computer.

[0031] According to a preferred embodiment, when the first sensor detects that the medical staff is away, the motor 301 is controlled to close the containing cover 1. When the second sensor detects that there is a sharp object in the opening, the motor 301 is controlled to keep the containing cover 1 normally open, and the motor 301 performs different working modes based on the different priorities of the instructions received. The first sensor in the present invention is arranged at the opening. When the medical staff puts a sharp object into the sharp object containing device, his hand will be close to the position of the first sensor. After the first sensor detects the behavior of the medical staff, the monitoring signal is sent to the control terminal, and the control terminal changes the state of the motor 301, and the motor 301 rotates the rotating partition 302 to open the opening. When the medical staff leaves, and the second sensor detects that the sharp object has fallen into the sharp object containing device, the control terminal controls the motor 301 to run in reverse, so that the opening is closed by rotating the rotating partition 302, without the need for the medical staff to manually close the opening.

[0032] The signals sent by the second sensor in the present invention are all of the second priority, that is, the second sensor is the main control sensor. The purpose of such design is that when the sharp object storage device handles sharp objects, it is necessary to handle sharp objects of different specifications and types. For example, short syringes, long syringes, glass, needles, etc., sharp objects of different sizes and lengths. When handling such sharp objects, different processing methods are required. When a long syringe is handled, because the tube body is too long, when storing, if the long syringe is directly put into the storage space, it will greatly waste the storage space, and even the longer syringe will pierce the sharp object container. In this regard, the present invention clamps the syringe and cuts it. During the cutting process, the friction block 402 remains in a clamped state so that the upper part of the syringe will not fly out toward the outside due to the torsional force. After the cutting is completed, the second sensor detects that the needle end has fallen into the storage body 2 under the action of gravity, thereby sending a signal, and the medical staff can choose to take away the remaining part of the syringe or put it into the storage body 2, and the opening is closed accordingly. Preferably, the second sensor can use a visual sensor or a laser sensor or an ultrasonic sensor to measure the size of the sharp object and the end of the needle entering the sharp object receiving device. The signal of the first sensor is the first priority, which is only used to control the forward and reverse rotation of the motor 301 by monitoring the hand behavior of the medical staff. When the second sensor also sends a signal for the motor 301, the second priority control signal of the second sensor is used to control the motor 301. That is, when the second sensor detects that the size of the sharp object placed is too large, a signal is sent to delay the closing of the opening to prevent the sharp object from not completely entering the sharp object receiving device when the opening is closed, causing damage to the device. When the sharp object placed in the sharp object receiving device is a small piece of glass or a needle, because of its small size, the second sensor does not send a signal to delay the closing of the opening. When the first sensor detects that the medical staff has no hand behavior (i.e., no more sharp objects are placed), a signal is sent to close the opening. At this time, the second sensor does not send a signal, and the first sensor of the first priority works, the opening is closed, and the sharp object is sealed in the sharp object receiving device.

[0033] Through these preferred schemes of the present invention, when accommodating sharp objects, at least the working mode can be selected according to the size of the sharp objects placed, including clamping the sharp objects or placing the sharp objects in the containing body or keeping the opening open or closing the opening. When the sharp object is detected by the first sensor and the second sensor before, during and after being placed in the sharp object containing device, the control terminal uses a multi-priority control method to enable the device to be used for accommodating a variety of sharp objects, which is particularly beneficial for medical personnel to use it in an all-round way. The variability of the treatment site determines that the sharp object containing device needs to handle different medical sharp objects in different occasions. In particular, it is a very important technical measure to place a large number of different medical sharp objects in the same containing device, handle different sharp objects and make full use of the containing space.

[0034] In addition, in the present invention, when the medical staff puts in the sharp object, the first sensor, the control terminal and the motor 301 provide the medical staff with the closing and closing of the opening, and at the same time, the internal components that monitor the medical staff's hand behavior need to be preheated. Since the time period required for placing the sharp object and then processing it is very short, if it cannot be processed in a fast manner but waits for the sharp object to enter the sharp object containing device and then starts separately in series, it is difficult to process the sharp object more efficiently. Utilizing the above-mentioned design scheme of the present invention, after the first sensor monitors the hand movement of the medical staff, in addition to sending a signal to make the motor 301 rotate forward or reverse, it also sends a signal to preheat the cylinder 401 in the second chamber 4. This signal is also used as the first priority. For example, when the second sensor detects the entry of the sharp object, it will send a signal to make the cylinder 401 act or not act. The signal of the second sensor is the second priority, and the preheating signal does not respond at this time. For this reason, the present invention is set to control the cylinder 401 not to act when the size of the sharp object cannot complete the clamping operation (for example, a needle or a small piece of glass) to reduce the load. When the second sensor detects that the size of the sharp object can complete the clamping operation (for example, a syringe), the cylinder 401 is controlled to clamp. Since the control judgment of the motor 301 is also being carried out, for the second sensor, what it monitors is the size of the sharp object, and it can use the same order of magnitude scale to judge the sharp object to reduce the amount of calculation. Preferably, the second sensor can use a visual sensor, a laser sensor, or an ultrasonic sensor to measure the size of the sharp object and the needle end entering the sharp object holding device. When the second sensor monitors the sharp object through optics, lasers, or ultrasound, the transition time between the second sensor and the sharp object is measured by the surface reflection of the sharp object, and then the transition time can be used as a measure of the size of the sharp object. In theory, all sensors that can measure distance can measure the size and size of the sharp object (for example, sensors based on the principles of grating, magnetic grating, capacitance, resistance, etc.), but in the current situation where fast and accurate measurement is required, the present invention selects the above-mentioned visual sensor, laser sensor, or ultrasonic sensor as the second sensor for monitoring, so that the scale standard used for the control of the motor 301 and the control of the cylinder 401 is of the same order of magnitude, thereby maximally limiting the reduction of system load.

[0035] It should be noted that the cylinder 401 is preheated in the present invention so that the cylinder 401 does not work due to a sudden command, and the sudden start-up is prevented from causing irreversible damage to the cylinder 401. Preheating means that the cylinder 401 is allowed to run slowly, so that the various components of the cylinder 401 are fully active, the wear of the cylinder 401 is reduced, and the instantaneous start-up of the cylinder 401 is prevented from wearing out the device, resulting in loss of sealing and disappearance of power. After preheating, the cylinder 401 can respond to the signal sent by the second sensor more quickly, and quickly clamp the sharp weapon, so as to prevent the situation where the medical staff throws the sharp weapon into the sharp weapon holding device too quickly, and the cylinder 401 is not clamped in time.

[0036] The first sensor can be placed on the surface of the containing cover 1 to ensure accurate monitoring of the medical staff's hand behavior, and the second sensor can be placed between the partition between the third chamber 5 and the second chamber 4, so that after the sharp weapon falls into the opening, its size, dimensions and needle end can be monitored after passing through the second chamber 4.

[0037] According to a preferred embodiment, the first chamber 3 of the containing cover 1 is provided with a rotating partition 302 for closing the opening. The rotating axis of the rotating partition 302 is not at the axis of the containing cover 1 and can close the opening when rotating around it. The rotation of the rotating partition 302 is controlled by the first sensor and the motor 301. When the medical staff needs to put the sharp object into the containing cover 1, the first sensor monitors the action of the medical staff and controls the working state of the motor 301 to rotate the rotating partition 302 to open the opening. The second chamber 4 is provided with a friction block 402 and a cylinder 401 for pushing or pulling back the friction block 402.

[0038] According to a preferred embodiment, the friction block 402 is fixedly connected to the pushing end of the cylinder 401, and at least two friction blocks 402 and two cylinders 401 push the two friction blocks 402 toward the axis of the containing cover 1 in opposite directions on the same straight line, and the two cylinders 401 are opened and closed at the same time, and their telescopic states and distances are the same. Preferably, the friction block 402 may be provided with a friction outer pattern. The two friction blocks 402 are tightly fitted and clamped with the sharp tool to increase the friction thereon, so that during the cutting process, the upper part of the sharp tool will not splash outward due to the torsional force. The friction pattern is set to be "fish scale" shaped, that is, an upward arrow-shaped pattern is formed to limit the upward movement of the sharp tool.

[0039] According to a preferred embodiment, the second chamber 4 is provided with a rectangular groove for accommodating the friction block 402 and the cylinder 401. The two cylinders 401 are respectively arranged on opposite sides of the rectangular groove. The midpoint of the rectangular groove is passed through by an opening.

[0040] According to a preferred embodiment, the third chamber 5 is provided with a first cutting knife 501, a second cutting knife 502 and two heating plates. The first cutting knife 501 and the second cutting knife 502 are arranged opposite to each other, and the two heating plates are arranged opposite to each other. The first cutting knife 501, the second cutting knife 502 and the two heating plates are located on the same horizontal plane. The first cutting knife 501, the second cutting knife 502 and the two heating plates are respectively located at the tips of the cross and can be pushed inward in sequence.

[0041] According to a preferred embodiment, a lifting platform 503 is provided vertically in the third chamber 5 for driving the first cutting knife 501, the second cutting knife 502 and the two heating plates to move vertically. The lifting platform 503 moves to the corresponding position of the needle end based on the size of the sharp object monitored by the second sensor. The first cutting knife 501, the second cutting knife 502 and the two heating plates are all provided with a pushing element. The first cutting knife 501, the second cutting knife 502 and the two heating plates are provided with a first working mode and a second working mode, and the first working mode and the second working mode are switched based on the selection of the medical staff and / or the size of the sharp object monitored by the second sensor. The first working mode refers to pushing the first cutting knife 501 and the second cutting knife 502 to directly cut the sharp object. The second working mode refers to pushing the two heating plates close to the sharp object for heating and plastic sealing, and then pushing the first cutting knife 501 and the second cutting knife 502 to cut the sharp object after completion. After the second sensor monitors the size of the sharp object placed in, it sends a signal, and the control terminal controls the lifting platform 503 to align with the needle end of the sharp object to cut it. The switching between the first working mode and the second working mode enables the device to further handle syringe-like sharp tools. The present invention heats the syringe tube body by a heating plate, thereby melting and pressing the syringe tube body together, and cutting is performed from the pressed side by the first cutting knife 501 and the second cutting knife 502, which facilitates the cutting of the cutting knife while keeping the syringe tube body as a closed mouth, thereby reducing the wear on the cutting knife blade. It should be noted that in the case of the second working mode, when the two heating plates are completely received in the third chamber 5 by the pushing assembly, the first cutting knife 501 and the second cutting knife 502 start to move, so as to prevent the heating plate from blocking the movement of the first cutting knife 501 and the second cutting knife 502. Preferably, the lifting platform 503 can be adjusted up and down by multiple cylinders.

[0042] According to a preferred embodiment, when the first sensor detects that medical personnel are approaching, it also controls the heating plate in the third chamber 5 to preheat. When the second sensor detects that the size of the sharp object is within the needle threshold and does not have a tube body, it controls the heating plate in the third chamber 5 to stop preheating and enter the first working mode. It should be noted that within the needle threshold in the present invention means that the size of the sharp object is within the range of a normally used needle, that is, between 0.45mm-1.6mm. Not having a tube body means that medical personnel may need to handle sharp objects such as suture needles that do not have an injection part, which only have a needle, that is, there is no part exceeding 1.6mm. The above-mentioned sizes are all the outer diameters of the needle.

[0043] According to a preferred embodiment, the first cutting knife 501 is set as a straight blade, and the second cutting knife 502 is set as a cross blade groove. The blade of the first cutting knife 501 corresponds to the blade groove of the second cutting knife 502 so that when the pushing element pushes the first cutting knife 501 and the second cutting knife 502, the first cutting knife 501 can fit with the second cutting knife 502. The second cutting knife 502 is set as a cross square groove. The vertical groove can be set as a slightly shallow placement groove with a certain width, and the horizontal groove is a deeper and sharp cutting groove. When the sharp tool is inserted therein, as the first cutting knife 501 and the second cutting knife 502 approach each other, the sharp tool is squeezed to the placement groove position and gradually clamped, and the first cutting knife 501 continues to penetrate into the fixed knife groove. Until the first cutting knife 501 completely penetrates into the horizontal groove, the sharp tool is affected by the three squeezing points and can be easily cut off. This cutting method is more labor-saving than traditional scissors, and the cross-shaped square groove design of the second cutting knife 502 prevents the cut needle from splashing and causing accidental injury to medical personnel.

[0044] According to a preferred embodiment, the outer edge of the open end of the containing body 2 is provided with an external thread, the containing cover 1 is provided with an internal thread portion that matches the external thread, the radius of the containing cover 1 is the same as that of the containing body 2, and the inner diameter of the internal thread is the same as the outer diameter of the containing body 2. Preferably, an ultraviolet lamp and / or a disinfectant spray nozzle may be provided in the containing body 2. The containing body 2 and the containing cover 1 are sealed by thread locking to prevent sharp objects from being exposed therefrom, and the ultraviolet sterilization lamp will not irradiate the outside of the containing body 2, and the sprayed disinfectant liquid will not penetrate out. When a failure occurs during the operation of the device, the internal and external thread structures of the containing body 2 and the containing cover 1 allow medical personnel to manually open the device, thereby avoiding the problem that the containing body 2 cannot continue to be used after a failure occurs.

[0045] Example 2

[0046] This embodiment is a further improvement on the above-mentioned embodiment, and the repeated contents will not be repeated here.

[0047] According to a preferred embodiment, the heating plate of the present invention can be connected to a control terminal. The device is also provided with a third sensor for obtaining the wall thickness scale related to the sharp object when the sharp object is placed in the heating plate area. The control terminal is used to obtain the degree of completion of the heat plastic sealing based on the wall thickness scale collected by the third sensor to adjust the push-pull degree of the pushing element. The second sensor can be a visual sensor, a laser sensor, or an ultrasonic sensor to measure the size and needle end of the sharp object placed in the heating plate area. When the second sensor monitors the sharp object through optics, lasers, or ultrasound, the transition time between the second sensor and the sharp object is measured by the surface reflection of the sharp object, and the transition time can be used as a measure of the size of the sharp object. The present invention selects the above-mentioned visual sensor, laser sensor, or ultrasonic sensor as the second sensor for monitoring. The size and wall thickness scale monitored by the second sensor and the third sensor are of the same scale, so that the two can be compared and calculated with each other. The third sensor can adopt Precitec's CHRocodile, which is an online monitoring device for high-speed wall thickness measurement. The third sensor can monitor the wall thickness of the tube into which the sharp object is placed, and combine it with the size of the sharp object monitored by the second sensor to obtain the degree of completion of the thermal plastic sealing.

[0048] The control terminal may be one or more of a computer, a portable mobile terminal, and a smart device. The portable mobile terminal may be, for example, one or more of a portable computer, a smart watch, smart glasses, a smart bracelet, and a tablet computer.

[0049] The second sensor monitors the width of the sharp tool (the gap between the two heating plates) during the melting and pressing process, and sends it to the control terminal for comparison and calculation with the wall thickness scale (the wall thickness of the sharp tool tube body) monitored by the third sensor when the sharp tool is just placed in the heating plate area, so as to obtain the degree of completion of the heat plastic sealing, which is used to control the pushing component. The specific process of obtaining the degree of completion of the heat plastic sealing is: the wall thickness scale is divided by the real-time size information, multiplied by a constant 2 and multiplied by 100%. When the degree of completion of the heat plastic sealing is greater than the threshold, the heat plastic sealing is completed, and when the degree of completion of the heat plastic sealing is less than or equal to the threshold, the heat plastic sealing is not completed. It should be noted that the threshold is unit one. The degree of completion of the heat plastic sealing is converted into a percentage to obtain its specific progress. When the degree of completion of the heat plastic sealing is greater than 100%, the heat plastic sealing is completed, and vice versa.

[0050] In the present invention, the degree of completion of heat plastic sealing refers to the index of the change in the thickness of the tube body of the sharp instrument when the sharp instrument is heat-sealed by the heating plate. The purpose of such design is to avoid the traditional control of the effect of heat plastic sealing, which can only rely on experiments and experience, and cannot determine the degree of heat plastic sealing. The seal may not be sealed, resulting in the internal residue in the medical sharp instrument flowing out, polluting the surrounding environment or infecting medical staff. Appropriate heat plastic sealing can save losses and extend the service life of the device. Usually, the sharp instrument that needs to be heat-sealed is a used syringe. If it is not heat-sealed, the residual liquid in the syringe may flow out. After the syringe tube body is melted and pressed together, the difficulty of cutting by the blade will be reduced, and both ports can remain closed after disconnection. When the sharp instrument is heat-sealed, at least the sharp instrument placed in the heating plate area can be automatically heat-sealed according to its size, wall thickness and needle end position. The control terminal is placed in the area of ​​the heating plate when the sharp weapon is sharp, and the process of heat sealing is automatically controlled by comparing and calculating the information monitored by the first sensor and the second sensor in real time, so that the present invention can be used in the heat sealing of sharp weapons of different sizes and different wall thicknesses. This processing method makes it no longer necessary for medical personnel to rely on experiments and experience to perform heat sealing, which can greatly improve the effect of heat sealing of the tube body and ensure that it forms two closed parts. This is also beneficial for the blade to cut off the tube body and reduce the loss of the blade. Automatically and quickly handling sharp weapons requires that the sharp weapon handling device has the ability to judge and control heat sealing, especially for heat sealing of sharp weapons of different sizes and different wall thicknesses, which is a very important technical measure.

[0051] According to a preferred embodiment, the push-pull element changes the push-pull degree in response to the thermoplastic sealing completion degree of the inserted sharp object, so that the thermoplastic sealing completion degree is greater than a threshold value, and the heating plate regulates the temperature based on the change of the thermoplastic sealing completion degree and the time period to reduce the thermoplastic sealing time. Preferably, since different sharp objects may have different materials and their melting point temperatures are different, it is difficult to control the heating plate to melt at the temperature just by collecting information in advance. If the current temperature of the heating plate is not enough to melt the sharp object tube body, excessive pressing will damage the push-pull element. In this regard, the present invention adjusts the heating temperature of the heating plate accordingly by controlling the thermoplastic sealing completion degree collected by the terminal and combining the time change. The push-pull element is a linear element, and the formula of the thermoplastic sealing completion degree is a linear formula. During the working process of the push-pull element, the thermoplastic sealing completion degree formed by it should show a linear growth. However, due to the different materials of the sharp objects, the heating plate cannot guarantee that the temperature can make the melting of the sharp objects also show a linear growth. Therefore, the slope formed by the thermoplastic sealing completion degree and time reflects the melting condition of the sharp object material. When the degree of completion of thermoplastic sealing shows a linear growth, the melting temperature of the sharp tool material is the current temperature of the heating plate, and there is no need to control the terminal to adjust its temperature. When the degree of completion of thermoplastic sealing shows a nonlinear growth (the growth of the degree of completion of thermoplastic sealing slows down, and due to the movement of the push-pull element, the degree of completion of thermoplastic sealing will not increase faster), it means that the current temperature of the heating plate is not enough to melt the sharp tool, and the temperature of the heating plate needs to be increased to complete the thermoplastic sealing. The factors affecting the degree of completion of thermoplastic sealing include not only the material of the sharp tool, but also the wall thickness, usage time, and residual liquid inside the sharp tool, but they can all be based on the relationship between the degree of completion of thermoplastic sealing and time, and the temperature of the heating plate can be adjusted by the control terminal. The present invention uses the degree of completion of thermoplastic sealing as a key condition for controlling the temperature of the heating plate, and solves various problems when the sharp tool is melted from the aspect of real-time dimensional information, including the influence of the wall thickness, usage time, and residual liquid inside the sharp tool, so as to achieve complete thermoplastic sealing of the sharp tool.
