Description

Technical Field

[0001] The present invention relates to the field of delivery technology, and in particular to a sterile delivery device for small nucleotide drugs. Background Art

[0002] In the context of the rapid development of medical technology, small nucleotide drugs, as the core components of new biological therapies, have shown great potential in the treatment of genetic diseases, tumor immunotherapy and other fields. However, in order to detect whether the efficacy and safety of small nucleotide drugs in manufacturing meet the inspection standards, it is necessary to conduct random inspections on the drugs after manufacturing.

[0003] During the random inspection process, the packaged medicine cans are usually placed into collection bottles for random inspection. During the transportation of the medicine from the storage bottle to the collection bottle, the tube mouth of the collection bottle and the bottle mouth of the storage bottle are easily exposed to the air, making the transportation process a weak link in the entire aseptic process. Especially during frequent random inspections, the risk of microbial contamination is increased during the process of opening and pouring into the collection bottle. During the transportation of the medicine, it is impossible to effectively detect whether the medicine is in a contaminated state, which affects the accuracy of subsequent random inspections.

[0004] In order to ensure that the medicine is always kept in a sterile state after entering the collection bottle and to ensure the quality of the final product, a sterile delivery device for small nucleotide medicines is designed. Summary of the invention

[0005] According to the problems raised in the background technology, the present invention provides a casting device for producing a hydraulic actuator to solve the problems. The present invention will be further explained below.

[0006] A sterile delivery device for small nucleotide drugs comprises a support frame, a delivery hard tube is fixedly connected to the top of the support frame, a transparent glass tube is fixedly connected to the upper part of the delivery hard tube, a bearing frame is fixedly connected to the bottom of the glass tube, a drainage needle is fixedly connected to the middle of the bearing frame in a through-type manner, a storage device is fixedly connected to the delivery hard tube, the storage device is composed of a hollow cylinder, a short tube and a long tube, and the bottom end of the drainage needle is connected to the top of the storage device; a pH and conductivity composite sensor is fixedly connected to the delivery hard tube, and a probe of the pH and conductivity composite sensor penetrates into the storage device; a motor is fixedly connected to the lower part of the delivery hard tube, the pH and conductivity composite sensor is electrically connected to the motor through a control module, the output shaft of the motor passes through the storage device, a rotating plate is rotatably connected to the storage device, an outflow hole is provided on the rotating plate, and the rotating plate is fixedly connected to the output shaft of the motor.

[0007] Preferably, the short tube of the delivery tube is connected to a delivery hose, the bottom of the delivery hose is connected to a collection bottle, and the collection bottle is set on the support frame. When the pH and conductivity of the small nucleotide medicine are normal, the outflow hole is connected to the short tube of the storage device, and the small nucleotide medicine will flow into the delivery hose and be collected by the collection bottle.

[0008] Preferably, the drainage needle is rotatably connected with a valve for adjusting the flow rate of the liquid medicine, and the opening of the flow channel in the drainage needle is controlled by adjusting the valve, thereby adjusting the flow rate of the medicine.

[0009] Preferably, a heating rod is fixedly connected in the delivery hard pipe, which converts electrical energy into thermal energy to accelerate the volatilization of residual cleaning liquid in the flow channel, thereby achieving drying and a certain sterilization and disinfection effect.

[0010] Preferably, the upper inner part of the delivery tube is fixedly connected to a first ultraviolet lamp, the lower inner part of the delivery tube is fixedly connected to a second ultraviolet lamp, and the components constituting the flow channel of the liquid medicine are made of transparent material. The light generated by the first ultraviolet lamp and the second ultraviolet lamp directly irradiates the flow channel to achieve the purpose of disinfection.

[0011] Preferably, the top of the conveying rigid tube is rotatably connected to a cover plate, a torsion spring is provided at the rotating connection, a contact switch is fixedly connected to the top of the conveying rigid tube, when the cover plate is closed, the cover plate contacts the contact switch, a fixed frame is fixedly connected to the front side of the conveying rigid tube, the sliding rod is slidably connected to the fixed frame, the cover plate is rotatably connected to a rotating buckle, the rotating buckle is snap-fitted with the sliding rod, a spring is fixedly connected between the cover plate and the rotating buckle, and a card slot is opened on the upper part of the fixed frame; the motor is a dual-axis motor, the top output shaft of which passes through the memory and is connected to the rotating plate, the bottom output shaft is fixedly connected to a space cam, and the sliding rod is slidably connected to the space cam; the control module adopts a dual-signal logic "and" control method to start the heating rod, the first ultraviolet lamp, and the second ultraviolet lamp, the first signal is triggered by the disinfection button, and the second signal is emitted by the contact switch being continuously pressed by the cover plate.

[0012] When the outflow hole is not aligned with the long tube of the storage device, the long tube is isolated from the flow channel to be sterilized. Even if the operator presses the sterilization button and covers the cover, the sliding rod is not in the locked state. At this time, the lower part of the rotating buckle cannot be locked into the slot under the elastic force of the spring. The cover will open and reset under the action of the torsion spring, and the contact switch cannot send the second signal, and the device cannot enter the sterilization mode. This is to ensure that the long tube of the storage device can be processed in the sterilization mode.

[0013] When the outflow hole is aligned with the long tube of the storage device, it indicates that the sliding rod is in a locked position. Even if the operator presses the disinfection button without closing the cover, there is only the first signal and the device cannot enter the disinfection mode. This is to ensure that the cover must be closed in the disinfection mode to prevent the operator from mistakenly using the conveying device in the sterilization state when the device is in the sterilization state.

[0014] When the operator does not press the disinfection button, no matter whether the outflow hole 115 of the device is aligned with the long tube of the storage 107 or whether the cover 201 is closed, the first signal cannot be sent and the device cannot enter the disinfection mode.

[0015] Preferably, the elastic telescopic rods are symmetrically distributed on both sides of the conveying tube, the bottom of the elastic telescopic rods is fixedly connected to the outer wall of the conveying tube, and a bearing plate is fixedly connected between the telescopic ends of the elastic telescopic rods, the bearing plate is used to bear the waste tube, and the bearing plate contacts the bottom of the conveying tube. People do not need to hold the waste tube with their hands all the time, when medicine needs to be loaded, pull down the bearing plate, the elastic telescopic rod is stretched, put the waste tube bottle on the bearing plate, let go, the elastic telescopic rod adaptively rebounds and drives the port of the waste tube to be inserted into the conveying tube; remove the waste tube, the elastic telescopic rod is completely reset and drives the bearing plate to move upward to cover the conveying tube, so that the first ultraviolet lamp and the second ultraviolet lamp are enclosed in the conveying tube for sterilization.

[0016] Beneficial effects: The present invention controls the dual-axis motor to drive the rotating plate to rotate through the detection of the PH and conductivity composite sensor, thereby realizing the automatic conversion and transportation of the medicine in the storage device. When the medicine is found to be contaminated or suspected of being contaminated, the transportation channel will be automatically switched to prevent the contaminated medicine from entering the collection bottle and affecting the subsequent sampling of the medicine. The dual-signal logic "and" control method of the present invention realizes the logic that when the heating rod, the first ultraviolet lamp, and the second ultraviolet lamp are turned on, the outflow hole must be aligned with the long tube of the storage device, and at the same time avoids the situation where the operator mistakenly continues to use the conveying equipment in the sterilization state when the equipment is in the sterilization state.

DETAILED DESCRIPTION

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments, but is not intended to limit the present invention.

[0030] A sterile delivery device for small nucleotide pharmaceuticals, such as Figure 1-Figure 5As shown, it includes a support frame 101, a delivery tube 102 is fixedly connected to the top of the support frame 101, a transparent glass tube 104 is fixedly connected to the upper part of the delivery tube 102, a carrier frame 105 is fixedly connected to the bottom of the glass tube 104, a drainage needle 106 for draining small nucleotide drugs is fixedly connected in the middle of the carrier frame 105, a storage 107 is fixedly connected in the middle of the delivery tube 102, and the storage 107 is composed of a hollow cylinder, a short tube and a long tube, and the bottom end of the drainage needle 106 is connected to the top of the storage 107; A pH and conductivity composite sensor 110 is fixedly connected to the middle of the hard tube 102, and the probe of the pH and conductivity composite sensor 110 penetrates into the storage 107; a motor 112 is fixedly connected to the lower part of the conveying hard tube 102, and the pH and conductivity composite sensor 110 is electrically connected to the motor 112 through a control module, and the output shaft of the motor 112 passes through the storage 107, and a rotating plate 113 is rotatably connected to the middle part of the storage 107, and the rotating plate 113 is provided with an outflow hole 115, and the rotating plate 113 is fixedly connected to the output shaft of the motor 112.

[0031] The lower part of the delivery tube 102 is connected to a delivery hose 114 for normal aseptic delivery of small nucleotide medicines. The short tube of the storage 107 is connected to the delivery hose 114. The bottom of the delivery hose 114 is connected to a collection bottle 116. The collection bottle 116 is arranged on the upper part of the support frame 101. When the pH and conductivity of the small nucleotide medicine are normal, the outflow hole 115 is connected to the short tube of the storage 107, and the small nucleotide medicine will flow into the delivery hose 114. The long tube of the storage 107 guides the liquid medicine to the bottom outlet of the delivery tube 102 and is collected by the collection bottle 116. When the pH and conductivity of the small nucleotide medicine are abnormal, the rotating plate 113 rotates under the drive of the motor 112, so that the outflow hole 115 is connected to the long tube of the storage 107, and the small nucleotide medicine flows out of the delivery tube 102 and enters the waste pipe.

[0032] When using the present device to transport small nucleotide medicines, first, tear off the protective film on the mouth of the small nucleotide medicine bottle, then insert the waste tube into the lower part of the transport hard tube 102, and insert the small nucleotide medicine bottle upside down into the upper part of the transport hard tube 102, so that the rubber at the mouth of the small nucleotide medicine bottle is aligned with the drainage needle 106, the drainage needle 106 pierces the rubber, and the liquid in the small nucleotide medicine bottle flows along the drainage needle 106 into the storage 107, and the pH and conductivity composite sensor 110 detects the pH value of the liquid in the storage 107. If the pH and conductivity composite sensor 110 detects that the pH value and conductivity of the liquid medicine are normally within the standard range, the pH and conductivity composite sensor 110 controls the output shaft of the motor 112 to rotate through the control module, thereby driving the rotating plate 113 to rotate, so that the outflow hole 115 on the rotating plate 113 is aligned with the short tube of the storage 107, and the liquid medicine in the storage 107 flows into the delivery hose 114 through the short tube, and is finally delivered to the collection bottle 116, and then the medicine is normally delivered; if the pH and conductivity composite sensor 110 detects that the pH value and conductivity of the liquid medicine deviate abnormally from the standard range, the pH and conductivity composite sensor 110 controls the output shaft of the motor 112 to rotate in the opposite direction through the control module, thereby driving the rotating plate 113 to rotate in the opposite direction, so that the outflow hole 115 on the rotating plate 113 is aligned with the long tube of the storage 107, and the liquid medicine in the storage 107 flows into the waste tube through the long tube, so that the liquid medicine in the waste tube can be sent for inspection conveniently, and the suspected contaminated medicine can be further inspected.

[0033] The drainage needle 106 is rotatably connected to a valve 109 for adjusting the flow rate of the liquid medicine. The valve 109 is adjusted to control the opening of the flow channel in the drainage needle 106, thereby adjusting the flow rate of the medicine.

[0034] Before starting to use the delivery device of the present invention and when changing the delivery agent, the delivery device needs to be cleaned, dried and disinfected to prevent the flow channel residue from interfering with the detection structure.

[0035] When cleaning, directly align the rubber of the cleaning bottle mouth with the drainage needle 106. The drainage needle 106 pierces the rubber, and the cleaning liquid inside is generally sterile water, which can flow into the conveying equipment to flush the flow channel. At this time, adjust the valve 109 to the maximum opening to flush the equipment at the maximum flow rate.

[0036] After cleaning, the residual cleaning liquid is dried. Specifically, a heating rod 111 is fixedly connected to the conveying hard tube 102. The heating rod 111 converts electrical energy into thermal energy, which is gradually transmitted to the flow channel of the conveying equipment through radiation, contact and convection, thereby accelerating the volatilization rate of the residual cleaning liquid in the flow channel, thereby achieving drying and a certain sterilization and disinfection effect.

[0037] After the drying treatment, the flow channel is disinfected. Specifically, a first ultraviolet lamp 103 is fixedly connected to the upper inner portion of the conveying rigid tube 102, and at least one second ultraviolet lamp 108 is fixedly connected to the lower inner portion of the conveying rigid tube 102. The components constituting the flow channel, such as the carrier frame 105, etc., are made of transparent materials such as acrylic. The light generated by the first ultraviolet lamp 103 and the second ultraviolet lamp 108 directly irradiates the flow channel to achieve the purpose of disinfection.

[0038] According to common sense, if the pH and conductivity composite sensor 110 detects that the pH value and conductivity of the liquid medicine deviate abnormally from the standard range, it means that the current liquid medicine is contaminated, and the medicine will flow out of the long tube of the storage 107, causing the flow channel formed by the long tube to be contaminated and must be cleaned and disinfected. In this embodiment, the conveying device includes two normal and abnormal states: in the normal state, the outflow hole 115 on the rotating plate 113 is aligned with the short tube of the storage 107, and the heating rod 111, the first ultraviolet lamp 103, and the second ultraviolet lamp 108 are not started to avoid ultraviolet rays and high temperature from interfering with the detection of the medicine; in the abnormal state, the outflow hole 115 on the rotating plate 113 is aligned with the long tube of the storage 107, and only in the abnormal state can the device be started to enter the disinfection mode, that is, when the heating rod 111, the first ultraviolet lamp 103, and the second ultraviolet lamp 108 are started, the outflow hole 115 must be aligned with the long tube of the storage 107.

[0039] In order to realize the logic that the outlet hole 115 must be aligned with the long tube of the storage 107 when the heating rod 111, the first ultraviolet lamp 103 and the second ultraviolet lamp 108 are started, and at the same time, in order to avoid the situation where the operator mistakenly continues to use the conveying equipment in a sterilization state when the equipment is in a sterilization state, the present invention adopts a dual-signal logic "and" control method to achieve it.

[0040] Specifically: it also includes a cover plate 201, which is rotatably connected to the top of the conveying rigid tube 102, and a torsion spring (built-in, not shown) is arranged at the rotating connection, a contact switch 202 is fixedly connected to the top of the conveying rigid tube 102, and when the cover plate 201 is closed, the cover plate 201 contacts the contact switch 202; a fixed frame 301 is fixedly connected to the front side of the conveying rigid tube 102, a sliding rod 302 is slidably connected to the fixed frame 301, the motor 112 is a double-axis motor, a top output shaft thereof passes through the storage 107 and is connected to the rotating plate 113, a bottom output shaft is fixedly connected to a space cam 303, the sliding rod 302 is slidably connected to the space cam 303, the cover plate 201 is rotatably connected to a rotating buckle 304, the rotating buckle 304 is snap-fitted with the sliding rod 302, a spring 305 is fixedly connected between the cover plate 201 and the rotating buckle 304, and a card slot 306 is opened on the upper part of the fixed frame 301.

[0041] When the pH and conductivity composite sensor 110 detects that the pH value and conductivity of the medicinal solution are normally within the standard range, the motor 112 drives the rotating plate 113 to rotate on the one hand, so that the outflow hole 115 is aligned with the short tube of the storage 107, and on the other hand, it also drives the space cam 303 to rotate. Due to the influence of the guide groove of the space cam 303, the sliding rod 302 does not move; when the pH and conductivity composite sensor 110 detects that the pH value of the medicinal solution deviates abnormally from the standard range, the motor 112 drives the rotating plate 113 to rotate on the one hand, so that the outflow hole 115 is aligned with the long tube of the storage 107, and on the other hand, it drives the space cam 303 to rotate. Due to the influence of the guide groove of the space cam 303, the motor 112 drives the sliding rod 302 to rise through the space cam 303.

[0042] After the disinfection button is pressed to send out the first signal, the cover 201 must be manually turned downward, and the cover 201 drives the rotating buckle 304 and the spring 305 to move downward together until the lower part of the rotating buckle 304 is stuck in the slot 306. In this way, during sterilization, the cover 201 can be locked, and the contact switch 202 is touched at this time to send out the second signal. Only after both signals are accepted by the control module will the heating rod 111, the first ultraviolet lamp 103, and the second ultraviolet lamp 108 be started, and the equipment enters the disinfection mode.

[0043] When the outflow hole 115 is not aligned with the long tube of the storage 107, the long tube is isolated from the flow channel to be sterilized. Even if the operator presses the sterilization button and covers the cover 201, because the sliding rod 302 is not in the locked state, the lower part of the rotating buckle 304 cannot be locked into the slot 306 under the elastic force of the spring 305, and the cover 201 will open and reset under the action of the torsion spring, and the contact switch 202 cannot send the second signal, and the device cannot enter the sterilization mode. This is to ensure that the long tube of the storage 107 can be processed in the sterilization mode.

[0044] When the outflow hole 115 is aligned with the long tube of the storage 107, it indicates that the sliding rod 302 is in a locked state. Even if the operator presses the disinfection button without closing the cover plate 201, there is only the first signal and the device cannot enter the disinfection mode. This is to ensure that the cover plate 201 must be in the closed state in the disinfection mode to prevent the operator from mistakenly using the delivery device in the sterilization state when the device is in the sterilization state.

[0045] When the operator does not press the disinfection button, no matter whether the outflow hole 115 of the device is aligned with the long tube of the storage 107 or whether the cover 201 is closed, the first signal cannot be sent and the device cannot enter the disinfection mode.

[0046] After the disinfection time of the cover 201 reaches the preset time, the contact switch 202 controls the motor 112 through the control module to drive the sliding rod 302 to descend through the space cam 303, so that the sliding rod 302 no longer blocks the upper part of the rotating buckle 304. At this time, the spring 305 is reset, so that the rotating buckle 304 can swing in the opposite direction until the lower part of the rotating buckle 304 is disengaged from the slot 306, and the cover 201 will be opened and reset under the action of the torsion spring. In this way, when the sterilization is completed, the cover 201 can be automatically opened to remind the operator that the sterilization is completed.

[0047] In summary, the spatial cam 303 drives the sliding rod 302 to rise and fall, thereby locking the rotating buckle 304, avoiding the staff from using the equipment without knowing it during the disinfection of the delivery tube 102 and the storage device 107, thereby causing secondary contamination of the medicines and equipment that need to be sampled.

[0048] like Fig.11 As shown, it also includes elastic telescopic rods 401 symmetrically distributed along the front and rear sides of the conveying rigid tube 102. The bottom of the elastic telescopic rods 401 is fixedly connected to the outer wall of the conveying rigid tube 102. A bearing plate 402 is fixedly connected between the telescopic ends of the elastic telescopic rods 401. The bearing plate 402 is used to support the waste tube, and the bearing plate 402 is in contact with the bottom of the conveying rigid tube 102.

[0049] People do not need to hold the waste tube with their hands all the time. When loading medicine, pull down the supporting plate 402, the elastic telescopic rod 401 is stretched, and the waste tube bottle is placed on the supporting plate 402. Let go, and the elastic telescopic rod 401 adaptively rebounds to drive the port of the waste tube to be inserted into the delivery tube 102. When suspected contamination occurs, the medicine flows into the waste tube. Then, remove the waste tube, and the elastic telescopic rod 401 is completely reset to drive the supporting plate 402 to move upward to cover the delivery tube 102, so that the first ultraviolet lamp 103 and the second ultraviolet lamp 108 are enclosed in the delivery tube 102 for sterilization.

[0050] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
