Description

[0002] Hematological malignancies are a type of malignant disease originating from the hematopoietic system, and mainly include subtypes such as leukemia, multiple myeloma, and malignant lymphoma. Anti-tumor drugs are the core treatment for such diseases, but there are significant challenges in the clinical use of these drugs: pediatric patients and critically ill patients often need to undergo pulverization to achieve drug dosage form conversion due to limited swallowing function or poor drug compliance. This demand has driven the technological development of tumor-specific drug crushing devices. For example, existing drug crushing devices usually use rotating pounding rollers to crush drugs. However, when the pounding rollers rotate and contact the drugs, the drugs are pushed by the pounding rollers and move.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] The technical terms in the following embodiments are explained:

[0025] An electromagnet is a device that generates a magnetic field through electric current and consists of two parts: a coil and an iron core. Its core characteristics are:

[0026] Controllable magnetism: a magnetic field is generated when power is on, and the magnetism disappears when power is off;

[0027] Adjustable magnetic strength: The magnetic field strength can be adjusted by changing the current or the number of coil turns;

[0028] Variable magnetic pole direction: The magnetic poles are switched by changing the direction of the current (following the right-hand screw rule).

[0029] 2. Working Principle: Magnetic Effect of Current

[0030] Magnetic field generation:

[0031] When current passes through a coil, a magnetic field is generated around the wire according to Oersted's experiment. The magnetic fields of the multiple turns of wire in the coil are superimposed, forming a stronger concentrated magnetic field.

[0032] Strengthening effect of iron core:

[0033] The iron core (usually a soft magnetic material such as soft iron or silicon steel) is magnetized by the external magnetic field, and its internal magnetic domains are arranged in an orderly manner. Superimposed with the magnetic field of the coil, the total magnetic field strength is increased by dozens or even hundreds of times.

[0034] Magnetic field disappears:

[0035] After power is cut off, the iron core quickly demagnetizes (characteristic of soft magnetic materials) and the magnetic field disappears.

[0036] Hydraulic rod: a precision actuator that converts hydraulic energy into mechanical energy

[0037] 1. Definition and Basic Structure

[0038] A hydraulic rod (hydraulic cylinder) is an actuator that converts hydraulic energy into linear reciprocating motion and is widely used in engineering machinery, aerospace, automobile manufacturing and other fields. Its core structure includes:

[0039] Cylinder: bears internal hydraulic pressure and is usually made of high-strength alloy steel or aluminum alloy;

[0040] Piston: A key component that converts hydraulic energy into mechanical energy, with chrome-plated surface to improve wear resistance;

[0041] Piston rod: connects the piston to the external load and needs to have high tensile strength and surface hardness;

[0042] Seal: To prevent hydraulic oil leakage, made of polytetrafluoroethylene (PTFE) or nitrile rubber (NBR);

[0043] End cover and buffer device: fix the piston rod and absorb movement impact to extend service life.

[0044] 2. Working Principle: Engineering Practice of Pascal's Law

[0045] Energy conversion:

[0046] The hydraulic pump converts mechanical energy into the pressure energy of hydraulic oil. The high-pressure oil enters the rodless cavity or rod cavity of the hydraulic rod through the control valve, pushing the piston to move. According to Pascal's law, pressure is evenly transmitted in a closed liquid. The formula is:

[0047] F=P×A

[0048] Among them, F is the output force, P is the system pressure, and A is the effective area of the piston.

[0049] Motion Control:

[0050] Extension: oil enters the rodless chamber and the piston rod moves outward;

[0051] Retraction: oil enters the rod chamber and the piston rod moves inward;

[0052] Floating: Oil flows through both chambers at the same time, and the piston rod can move freely (such as excavator boom buffer).

[0053] Buffering and speed regulation:

[0054] End buffer: When the piston approaches the end of the stroke, the hydraulic oil is depressurized through the throttle hole to avoid hard impact;

[0055] Speed regulating valve: adjusts the piston movement speed by controlling the flow rate (usually 0.01-1m / s).

[0056] 3. Application Fields

[0057] Construction machinery:

[0058] Excavator: Hydraulic rods drive the boom, arm and bucket to achieve digging and loading actions;

[0059] Crane: A multi-stage hydraulic rod combination provides a lifting force of hundreds of tons.

[0060] Aerospace:

[0061] Landing gear retraction and extension: The hydraulic rod withstands the impact of aircraft landing and is required to work reliably in extreme temperatures (-55°C to 125°C);

[0062] Rudder control: High-precision hydraulic levers adjust flight attitude, with a response time of <0.1 seconds.

[0063] auto industry:

[0064] Suspension system: Hydraulic rods buffer road vibrations and improve ride comfort;

[0065] Braking system: Hydraulic lever transmits pedal force to achieve rapid braking.

[0066] Industrial Automation:

[0067] Press: Hydraulic rods provide several meganewtons of pressing force to process metal sheets;

[0068] Robot: Hydraulic rods drive joints to achieve heavy-load handling (loads up to several tons).

[0069] Reference Figures 1 to 3 As shown, the present invention provides a device for crushing blood tumor medicine, including a box body 1, in which a crushing mechanism, an air cooling mechanism, a grinding mechanism and a collection plate 2 are arranged in sequence from top to bottom; the grinding mechanism includes a rotating rod 26 rotatably connected to the top wall of the box body 1, the top of the rotating rod 26 is connected to the output shaft of the driving motor 14, the bottom end of the rotating rod 26 is connected to the grinding head 25, the bottom end of the grinding head 25 is in friction contact with the grinding plate 22, the grinding plate 22 is connected to a reciprocating assembly, the grinding plate 22 reciprocates through the reciprocating assembly, a discharge hole 24 is opened on the grinding plate 22, a gate valve assembly is provided on the discharge hole 24, and a screening assembly is provided below the discharge hole 24.

[0070] The crushing mechanism completes the initial granulation of the drug, and the dynamic friction between the grinding head 25 and the reciprocating grinding disc 22 in the grinding mechanism achieves fine grinding, significantly improving the uniformity of the drug pulverization. The air cooling mechanism cools the rotating rod 26 and the grinding head 25 to prevent drug decomposition at high temperatures. The screening component, combined with the intermittent opening strategy of the feed hole gate valve, can achieve precise control of drug particles to meet the particle size requirements of the drug administration route.

[0071] Furthermore, the crushing mechanism includes a conical bucket 9 fixedly connected to the inside of the box body 1, the rotating rod 26 is coaxially arranged with the conical bucket 9, and the rotating rod 26 passes through the discharge port of the conical bucket 9. The sliding sleeve on the rotating rod 26 is provided with a cone 11, and the outer wall of the cone 11 is connected to a plurality of triangular cones 10. The cone 11 is arranged above the conical bucket 9, and a telescopic component is provided on the rotating rod 26. The telescopic component is used to drive the cone 11 to move along the rotating rod 26 and press toward the conical bucket 9. A plurality of feed pipes 15 are circumferentially arranged on the outer wall of the box body 1, and the feed pipes 15 are located between the cone 11 and the conical bucket 9.

[0072] The telescopic assembly drives the cone 11 to press against the inner wall of the conical bucket 9, and pierces the medicine through the multiple triangular pyramids 10, so that the medicine is broken into small pieces.

[0073] Furthermore, the telescopic assembly includes a support plate 13 fixedly connected to the rotating rod 26 , a plurality of hydraulic rods 12 are circumferentially connected to the bottom end of the support plate 13 , and the output ends of the hydraulic rods 12 are connected to the top end of the frustum 11 .

[0074] By controlling the synchronous extension of multiple hydraulic rods 12, the frustum 11 and the triangular pyramid 10 are driven to pierce the medicine. During this process, the drive motor 14 can also be started to drive the rotating rod 26 and the frustum 11 to rotate, thereby further improving the crushing effect.

[0075] Furthermore, the reciprocating assembly includes a rack 2 6 and a rack 1 3 that pass through the side wall of the box body 1. A motor 5 is installed on the outer wall of the box body 1. The output end of the motor 5 is connected to a half gear 4. The half gear 4 is alternately engaged with the rack 1 3 and the rack 2 6. The ends of the rack 2 6 and the rack 1 3 away from the motor 5 are connected to the abrasive disc 22. The end of the abrasive disc 22 away from the rack 1 3 is connected to one end of the slide rod 19. The other end of the slide rod 19 is slidably connected to the side wall of the box body 1.

[0076] The motor 5 drives the half gear 4 to rotate. When the half gear 4 is engaged with the rack 2 6 for transmission, the rack 2 6 drives the abrasive disc 22 to move forward in the horizontal direction. As the half gear 4 separates from the rack 2 6, the half gear 4 establishes an engaged transmission relationship with the rack 1 3. At this time, the rack 1 3 drives the abrasive disc 22 to move backward in the horizontal direction, thereby realizing the reciprocating motion of the abrasive disc 22 and improving the grinding effect.

[0077] Furthermore, the gate valve assembly includes a sealing plate 27, a slide groove 33 is opened on one side of the abrasive disc 22, the discharge hole 24 passes through the slide groove 33 longitudinally, the sealing plate 27 is slidably connected in the slide groove 33, and one end of the spring 23 is fixedly connected to the side wall of one end of the slide groove 33, and the other end of the spring 23 is connected to the sealing plate 27. A through hole 28 is opened on the end of the sealing plate 27 away from the spring 23, and the aperture of the through hole 28 is not smaller than the discharge hole 24, and is arranged corresponding to the discharge hole 24. The end of the sealing plate 27 away from the spring 23 is connected to a magnet block 29, and an electromagnet 30 is arranged on the side wall of the slide groove 33 opposite to the magnet block 29, and the magnetic pole of the magnet block 29 is opposite to the magnetic pole of the magnet block 29.

[0078] In the initial state, the closing plate 27, under the action of the spring 23, makes the magnet block 29 fit with the electromagnet 30. At this time, the electromagnet 30 is in a power-off state, and the through hole 28 is in the slide groove 33, thereby achieving the blocking of the discharge hole 24. When discharge is required, the electromagnet 30 is powered on to generate magnetic poles that are opposite to the magnetic poles of the magnet block 29, causing repulsion. The magnet block 29 drives the closing plate 27 to compress the spring 23 so that the through hole 28 and the discharge hole 24 coincide with each other to achieve discharge.

[0079] Furthermore, the screening assembly includes a screen plate 20 hinged to the bottom end of the abrasive disc 22 , and one end of the screen plate 20 away from the hinged end is elastically connected to the bottom end of the abrasive disc 22 via a spring 21 .

[0080] Furthermore, one end of a cross bar 31 is horizontally connected to the inner wall of the box body 1 , and the other end of the cross bar 31 is connected to a wedge block 32 . The wedge block 32 is in sliding contact with the sieve plate 20 , and the wedge block 32 forces the sieve plate 20 to rotate.

[0081] When the abrasive disc 22 makes reciprocating motion, the sieve plate 20 is forced to contact with the wedge block 32. Under the action of the wedge block 32, the sieve plate 20 is compressed by the spring and rotates. When the abrasive disc 22 moves in the opposite direction, the sieve plate 20 is separated from the wedge block 32 and the sieve plate 20 is reset under the action of the spring 21. During this process, the sieve plate 20 swings up and down, further improving the screening effect.

[0082] Furthermore, in order to ensure that the crushed medicine can fall smoothly onto the abrasive disc 22, a discharge pipe 16 is connected to the discharge port of the conical bucket 9. The discharge pipe 16 is coaxially sleeved outside the rotating rod 26. A spiral leaf 18 is fixedly wound on the outer wall of the rotating rod 26 in the interval section of the discharge pipe 16, and the spiral leaf 18 is in friction contact with the inner wall of the discharge pipe 16.

[0083] Furthermore, the air cooling mechanism includes air ducts 7 arranged at equal intervals along the circumferential direction of the inner wall of the box body 1, the air ducts 7 are arranged horizontally, and a fan 8 is provided at one end of the air duct 7 close to the discharge pipe 16. A plurality of fins 17 are connected circumferentially on the outer wall of the discharge pipe 16, and two water channels 35 are opened inside the rotating rod 26. Both water channels 35 are connected to the water storage chamber provided in the abrasive head 25. A circulating water pump 34 is provided in the rotating rod 26, and the circulating water pump 34 is located in the interval section of the discharge pipe 16, wherein the other end of one water channel 35 is connected to the water inlet end of the circulating water pump 34, and the other end of the other water channel 35 is connected to the water outlet end of the circulating water pump 34.

[0084] The air ducts 7 arranged at equal intervals around the inner wall of the box body 1 form an annular air flow channel, which cooperates with the fan 8 to force convection, cools the discharge pipe 16, and exchanges heat with the spiral blades 18 and the rotating rod 26 to cool the grinding head 25. Specifically, the circulating water pump 34 establishes heat exchange between the water storage chamber set in the grinding head 25 and the spiral blades 18, thereby realizing all-round heat exchange between the drug particles and the grinding parts, effectively preventing the degradation of the active ingredients of the drug due to local overheating.

[0085] Furthermore, in order to prevent the drug from spreading everywhere, a cover 36 is connected to the bottom end of the feed pipe 16 . The cover 36 is arranged outside the abrasive head 25 , and the bottom end of the cover 36 is in friction contact with the abrasive disc 22 .

[0086] The device for crushing blood tumor medicine provided by the present invention has the following working principles: when in use, medicine is added into the conical bucket 9 through the feeding pipe 15, and then the telescopic component is started, which drives the cone 11 to press against the inner wall of the conical bucket 9 and pierces the medicine through multiple triangular pyramids 10, so that the medicine is broken into small pieces, and the telescopic component is controlled to shrink so that the cone 11 reciprocates and intermittently presses against the medicine, and then the driving motor 14 is started, and the driving motor 14 drives the rotating rod 26 and the cone 11 to rotate, further improving the crushing effect, and at the same time, the rotating rod 26 drives the spiral blade 18 to push the medicine that slides into the discharge pipe 16 into the cover body 36 to prevent it from spreading everywhere, and then the motor 5 is started, and the motor 5 drives the half gear 4 to rotate. When the half gear 4 is meshed with the rack 2 6 for transmission, Rack 26 drives the abrasive disc 22 to move forward in the horizontal direction. As the half gear 4 separates from the rack 26, the half gear 4 establishes a meshing transmission relationship with the rack 1 3. At this time, the rack 1 3 drives the abrasive disc 22 to move backward in the horizontal direction, thereby realizing the reciprocating motion of the abrasive disc 22 and improving the grinding effect. At the same time, the air cooling mechanism is started to cool the abrasive head 25. When discharge is required, the electromagnet 30 starts to power on, and the magnetic poles generated by the electromagnet 30 are opposite to the magnetic poles of the magnet block 29, causing repulsion. The magnet block 29 drives the sealing plate 27 to compress the spring 23 so that the through hole 28 coincides with the discharge hole 24 to realize discharge. The ground medicine falls smoothly onto the sieve plate assembly through the discharge hole 24 for screening, and the qualified medicine falls onto the collection plate 2 through the sieve hole for collection.
