Description

Technical Field

[0001] The invention relates to a drug delivery device, in particular to a drug delivery device convenient for tumor nursing, belonging to the technical field of tumor nursing drug delivery. Background Art

[0002] The Department of Oncology is mainly engaged in the medical treatment of various benign and malignant tumors. The treatment of tumors has entered the era of comprehensive treatment. In the process of a series of treatments in the Department of Oncology, targeted medication is required according to the patient's condition at each stage for auxiliary treatment. Drug delivery devices need to be used frequently. Current drug delivery devices include syringes, intravenous infusion sets, etc.

[0003] A Chinese invention patent with authorization announcement number CN111467602B discloses a drug delivery device for oncology nursing that is convenient and precisely controlled, including a shield, a connecting portion, and a mounting portion for fixing the drug delivery device, wherein the connecting portion is fixedly connected between the shield and the mounting portion, a power device is fixed on the top of the connecting portion, an adjustment mechanism is provided above the middle portion of the shield, and a rotating device is connected between the adjustment mechanism and the power device; the adjustment mechanism consists of a fixed outer sleeve and a movable inner sleeve, wherein: a plurality of first through holes are provided on both sides of the fixed outer sleeve, a second through hole is provided on both sides of the movable inner sleeve, and the first through holes cooperate with the second through holes, and a pushing device is movably installed on the bottom of the movable inner sleeve.

[0004] It can be understood that the above invention can adjust the drug dosage flow rate through a series of linkage structures. However, the way to adjust the flow rate is still achieved with the help of a driving device. The specification also clearly states that the driving device is manual or electric. Although the manual driving method can adjust the drug flow rate, it is very unstable and the drug delivery rate depends entirely on manual labor. Although the electric method is stable, the drug flow rate can only be adjusted by adjusting the motor working mode, which requires a high degree of intelligence for the motor and high production costs. At the same time, the existing tumor care process requires not only drug administration, but also frequent extraction of body fluids and tissue fluids. The above patent does not have this function. At the same time, it is currently impossible to achieve two functions simultaneously through a single drug delivery device on the market. The use of a single device to simultaneously inject drugs and extract body fluids seriously affects the sanitary conditions and may have a negative impact on the patient's body. In view of this, this application is proposed. Summary of the invention

[0005] The purpose of the present invention is to provide a drug delivery device for convenient tumor care in order to solve the above-mentioned problems. The device can control the winding of the flexible connection part by switching winding drums of different diameters to adjust the drug delivery rate. The winding rate depends entirely on the replacement of the winding drum, which can effectively ensure the stability of the lifting and lowering rate of the lifting baffle and will not cause fluctuations in the drug delivery rate. At the same time, both drugs and patient body fluids can be collected and controlled through the device, and the cavities are separated while sharing a driving system, which has stronger functionality and better hygiene.

[0008] The wire reel further comprises a combined wire winding control component, wherein a rotating drive component for driving the combined wire winding control component to rotate and a horizontal push drive component for driving the combined wire winding control component to move horizontally are respectively installed on both sides of the inner wall of the shell near the top. The combined wire winding control component consists of a square cylinder and a plurality of wire reels with different diameters fixedly arranged on the outer wall of the square cylinder, each of which is provided with a threaded wire groove, and the wire reel is detachably connected to the flexible connecting part. In a specific application process, by switching wire reels of different diameters to be connected to the flexible connecting part, the wire reels of different diameters can control the winding of the flexible connecting part, thereby realizing the adjustment of the volume change rate of the first cavity and the second cavity, and further realizing the adjustment of the medium transfer rate in the first cavity and the second cavity.

[0009] Preferably, the square cylinder is provided with longitudinally retractable electric push rods on the upper and lower sides facing the transverse pushing drive member, and the telescopic end of the electric push rod is fixedly connected with a semicircular threaded tube. The upper and lower semicircular threaded tubes are butt-jointed to form a circular threaded tube that can be threadedly connected to the transverse pushing drive member, so that the two semicircular threaded tubes can be selectively connected to the transverse pushing drive member, and the two are controlled to be connected when transverse pushing control is required, otherwise they are disconnected.

[0010] Preferably, the rotating drive component is composed of a first motor fixed on the inner wall of the shell and a square rotating rod connected to the output shaft of the first motor. The rotating rod is sleeved in the square cylinder, and the two are in a state where they can move laterally relative to each other but cannot rotate relative to each other. During actual use, the rotating rod is driven to rotate by turning on the first motor, thereby driving the square cylinder and the winding drum on the square cylinder to rotate, thereby realizing the winding control of the flexible connection part.

[0011] Preferably, the transverse push drive component is composed of a second motor fixed on the inner wall of the shell and a screw connected to the output shaft of the second motor, the screw is connected to a circular threaded tube formed by connecting the two semicircular threaded tubes, and the screw is driven to rotate by turning on the second motor. When the two semicircular threaded tubes are connected to form a circular threaded tube, the circular threaded tube and the square cylinder can be pushed to move horizontally synchronously, thereby realizing the position adjustment of the winding drum on the square cylinder. After reaching the specified position, the two semicircular threaded tubes are controlled to separate, and the indirect control of the screw over the square cylinder is released. At this time, the square cylinder can be flexibly rotated under the rotation of the rotating rod.

[0012] Preferably, one end of the screw rod is rotatably connected to a square anti-skid sheet, which is in close contact with the inner wall of the square cylinder. The square cylinder is fixed in a lateral position by the anti-skid sheet to prevent the square cylinder from moving horizontally left or right after the screw rod releases its control over the square cylinder. Although the anti-skid sheet has great friction with the inner wall of the square cylinder, it is still in a movable state when the screw rod pushes the circular threaded tube and the square cylinder to move, and does not affect the operation of the overall structure.

[0013] Preferably, the flexible connection part includes a multi-section electric push rod fixed on the top of the transverse partition, a connecting pin fixed on the top of the multi-section electric push rod, an adsorption sheet fixedly connected to the top of the connecting pin by adsorption, and a connecting rope fixed to the bottom of the adsorption sheet.

[0014] Preferably, an electromagnetic sheet is fixedly provided on the connecting end of the connecting needle and the adsorption sheet, which can adsorb and fix the adsorption sheet after being turned on. A docking hole for inserting the adsorption sheet is provided in the threaded wire groove of each wire reel. A magnet sheet is provided in the docking hole. The magnetic force of the electromagnetic sheet after being turned on is greater than the magnetic force of the magnet sheet, so that the electromagnetic sheet can suck the adsorption sheet out of the docking hole. In actual use, the electromagnetic sheet adsorbs and fixes the adsorption sheet, and the position of the adsorption sheet is controlled by the extension and contraction of the multi-stage electric push rod. After the screw rod rotates to control the winding reel to move to the desired position, the multi-stage electric push rod is extended to control the connecting needle to rise, and then the adsorption sheet is inserted into the docking hole. Then the electromagnetic sheet is closed, and the adsorption sheet and one end of the connecting rope are fixed in the winding reel under the adsorption action of the magnet sheet. Thereafter, the winding reel can be rotated by turning on the first motor to realize the winding function.

[0015] Preferably, the lifting partition is composed of a sealing plate that is close to the inner wall of the shell and the inside of the longitudinal partition frame, and an elastic contraction connecting rod fixed to the inner wall of the bottom of the shell. The top telescopic end of the elastic contraction connecting rod is fixedly connected to the sealing plate. The elastic contraction connecting rod remains in a contracted state under normal circumstances, and the sealing plate is pulled to a low position, which can be used to pull down the sealing plate at a high position to complete the suction work. It can also be automatically reset after use to facilitate the next drug administration work. A longitudinal connecting rod is fixedly provided on the top of the sliding bracket, and the top of the longitudinal connecting rod is fixedly connected to the bottom of the sealing plate through a claw-type bracket. The connection structure is stable and has high strength.

[0016] Preferably, a visual camera is fixed on the top inner wall of the shell for detecting the relative positions of the combined winding control component and the flexible connection part in real time. In actual use, an intelligent controller is provided in the device, and each electrical component is intelligently controlled through the cooperation of the intelligent controller and the visual camera, so that the caregiver only needs to press the corresponding control switch to automatically adjust to the required mode. The visual camera mainly confirms whether the docking hole is aligned with the adsorption sheet, and the connection can be carried out after confirmation of alignment.

[0017] Preferably, the housing is provided with two medium inlet and outlet ports, which are respectively located on one side of the top of the first cavity and the second cavity, the medium inlet and outlet port located on one side of the first cavity is used for drug input and discharge, and the medium inlet and outlet port located on one side of the second cavity is used for body fluid suction and discharge, so as to realize basic drug administration or body fluid suction functions;

[0018] The shell is also embedded with two strip-shaped observation panels made of transparent material that penetrate the shell wall. The two observation panels are respectively located on one side of the first cavity and the second cavity, so as to facilitate observation of the internal conditions of the first cavity and the second cavity;

[0019] A control switch for controlling the volume change of the first cavity and the second cavity and adjusting the change rate is fixedly arranged on the outer wall of the shell, which is convenient for nursing staff to perform intelligent control.

[0020] The beneficial effects of the present invention are:

[0021] 1. The winding of the flexible connection part is controlled by a combined winding control part, and the sliding bracket is lifted up by the lower end of the flexible connection part, thereby pushing the lifting partition up, so as to push the medicine in the first cavity out and realize the drug administration process. The winding speed of the combined winding control part is achieved by replacing winding drums of different diameters. The rotation speed of the motor does not need to be adjusted before and after replacement, and the intelligence level of the motor is relatively low. The winding speed depends entirely on the replacement of the winding drum. This method can effectively ensure the stability of the lifting speed of the lifting partition, and there will be no fluctuation in the drug administration rate, which greatly improves the stability of drug administration in the tumor care process.

[0022] 2. The spatial volume of the first cavity and the second cavity is controlled by the lifting movement of the lifting partition, and the discharge of drugs in the first cavity and the second cavity or the inhalation of external media is controlled by the change of the spatial volume. Both drugs and patient body fluids can be collected and controlled through this application, and the cavities are separated while sharing a driving system. Compared with existing drug delivery devices, it has stronger functionality and better hygiene. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1-Figure 11As shown, a drug delivery device for convenient tumor care includes a mounting back plate 1 for fixing on a wall to provide support and a shell 2 arranged on the mounting back plate 1, a transverse partition 3 is fixed in the inner cavity of the shell 2, a longitudinal partition frame 4 is arranged at the bottom center position of the transverse partition 3 and distributed front and back, a T-shaped structure is formed between the transverse partition 3 and the longitudinal partition frame 4, two separated spaces are provided on both sides of the longitudinal partition frame 4, a lifting partition 5 is arranged between the two sides of the longitudinal partition frame 4 and the inner wall of the shell 2, the lifting partition 5 is normally located relatively below the longitudinal partition frame 4, a first cavity 14 and a second cavity 15 are formed in the inner cavity of the shell 2 by the transverse partition 3, the longitudinal partition frame 4 and the lifting partition 5, the first cavity The first cavity 14 and the second cavity 15 are used for discharging drug storage and sucking body fluid storage, respectively. The spatial volume of the first cavity 14 and the second cavity 15 is controlled by the lifting movement of the lifting partition 5. The drug discharge in the first cavity 14 and the second cavity 15 or the external medium is sucked in by the change of the spatial volume. Two medium inlet and outlet ports 11 are provided on the shell 2. The two medium inlet and outlet ports 11 are respectively located on one side of the top of the first cavity 14 and the second cavity 15. The medium inlet and outlet port 11 located on one side of the first cavity 14 is used for drug input and discharge, and the medium inlet and outlet port 11 located on one side of the second cavity 15 is used for body fluid suction and discharge, so as to realize the basic drug administration or body fluid suction function;

[0037] The shell 2 is also embedded with two strip-shaped observation panels 12 made of transparent material that penetrate the shell wall. The two observation panels 12 are respectively located on one side of the first cavity 14 and the second cavity 15 to facilitate observation of the internal conditions of the first cavity 14 and the second cavity 15.

[0038] In actual use, when medication is required, the lifting baffle 5 is controlled to be at a low position, and then the medicine is injected into the first cavity 14, the injection tool catheter is connected to the first cavity 14, and then the lifting baffle 5 is controlled to rise, and the medicine in the first cavity 14 is sent to the injection tool for medication. When the patient's body fluid needs to be sucked, the lifting baffle 5 is first controlled to rise to a high position, and then one end of the catheter is placed in the part of the patient where the body fluid needs to be extracted, and the other end is connected to the second cavity 15, and then the lifting baffle 5 is controlled to descend, and the space of the second cavity 15 is increased to reduce the air pressure in the cavity, so that the body fluid at one end of the catheter is sucked. Both the medicine and the patient's body fluid can be collected and controlled by the present application, and the cavities are separated while sharing a driving system. Compared with the existing medication device, it has stronger functionality and better hygiene.

[0039] The inner walls of the housing 2 on both sides near the bottom are symmetrically provided with longitudinally distributed slide grooves, and a sliding bracket 10 is provided between the slide grooves. A flexible connection part 9 is fixedly provided on the top of the transverse partition 3, and one end of the bottom of the flexible connection part 9 passes through the transverse partition 3 and the longitudinal partition frame 4 and is fixedly connected to the center position of the sliding bracket 10;

[0040] The housing 2 further comprises a combined wire winding control member 6. A rotating drive member 7 for driving the combined wire winding control member 6 to rotate and a horizontal push drive member 8 for driving the combined wire winding control member 6 to move horizontally are respectively installed on both sides of the inner wall of the housing 2 near the top. The combined wire winding control member 6 consists of a square cylinder 601 and a plurality of wire winding drums 602 with different diameters fixedly arranged on the outer wall of the square cylinder 601. A threaded wire groove 603 is provided on each wire winding drum 602. The wire winding drum 602 is detachably connected to the flexible connecting portion 9. In specific applications, by switching wire winding drums 602 with different diameters to be connected to the flexible connecting portion 9, the wire winding drums 602 with different diameters can control the winding of the flexible connecting portion 9, so as to adjust the volume change rate of the first cavity 14 and the second cavity 15, thereby adjusting the medium transfer rate in the first cavity 14 and the second cavity 15. The design of the threaded wire groove 603 on the wire winding drum 602 can ensure that no stacking and entanglement occurs between the flexible connecting portions 9, thereby further ensuring the stability of the wire winding operation.

[0041] When the device is actually used, the transverse push drive 8 is used to push the square cylinder 601 to move horizontally relative to the rotary drive 7, thereby adjusting the position of each winding drum 602 on the square cylinder 601 relative to the lower flexible connection part 9, so that the flexible connection part 9 can be inserted into different winding drums 602 after rising to be fixed and then wound up. The rotation rate of the rotary drive 7 is constant, so winding drums 602 of different diameters can achieve different winding rates at the same rotation speed, so as to achieve the adjustment of the volume change rate of the first cavity 14 and the second cavity 15. In summary, the present application controls the winding of the flexible connection part 9 through the combined winding control part 6, and uses the lower end of the flexible connection part 9 to lift and drive the sliding bracket 10 upward The lifting speed of the combined winding control component 6 is achieved by replacing winding drums 602 of different diameters. The rotation speed of the motor does not need to be adjusted before and after the replacement, and the intelligent level of the motor is relatively low. The winding speed completely depends on the replacement of the winding drum 602. This method can effectively ensure the stability of the lifting speed of the lifting baffle 5, and there will be no fluctuation in the drug administration rate. In particular, compared with the prior art by adjusting the working mode of the motor or the hydraulic parts, the drug administration rate is constant because it does not rely on the power change of electrical components, which greatly improves the stability of drug administration in the tumor care process.

[0042] Specific as Figure 7As shown, the square cylinder 601 is provided with longitudinally retractable electric push rods 604 on the upper and lower sides facing the transverse pushing drive member 8, and a semicircular threaded tube 605 is fixedly connected to the retractable end of the electric push rod 604. The upper and lower semicircular threaded tubes 605 are connected to form a circular threaded tube that can be threadedly connected to the transverse pushing drive member 8, so that the two semicircular threaded tubes 605 can be selectively connected to the transverse pushing drive member 8. When transverse pushing control is required, the two are controlled to be connected, otherwise they are disconnected.

[0043] Specific as Figure 6 As shown, the rotating drive member 7 is composed of a first motor 701 fixed on the inner wall of the shell 2 and a square rotating rod 702 connected to the output shaft of the first motor 701. The rotating rod 702 is sleeved in the square cylinder 601, and the two are in a state where they can move laterally relative to each other but cannot rotate relative to each other. In actual use, the rotating rod 702 is driven to rotate by turning on the first motor 701, thereby driving the square cylinder 601 and the winding drum 602 on the square cylinder 601 to rotate, thereby realizing the winding control of the flexible connection part 9.

[0044] Specific as Fig. 9 As shown, the transverse push drive member 8 is composed of a second motor 801 fixed on the inner wall of the housing 2 and a screw rod 802 connected to the output shaft of the second motor 801. The screw rod 802 is connected to a circular threaded tube formed by two semicircular threaded tubes 605 connected together. The screw rod 802 is driven to rotate by turning on the second motor 801. When the two semicircular threaded tubes 605 are connected together to form a circular threaded tube, the circular threaded tube and the square cylinder 601 can be pushed to move horizontally synchronously, thereby adjusting the position of the winding drum 602 on the square cylinder 601. After reaching the specified position, the two semicircular threaded tubes 605 are controlled to separate, and the screw rod 802 is released from the square cylinder 60 1, at this time, the square cylinder 601 can be flexibly rotated under the rotation of the rotating rod 702, and one end of the screw rod 802 is rotatably connected with a square anti-skid sheet 803, and the anti-skid sheet 803 is tightly attached to the inner wall of the square cylinder 601, and the square cylinder 601 is fixed in the lateral position by the anti-skid sheet 803 to prevent the square cylinder 601 from moving horizontally left and right after the screw rod 802 releases the control of the square cylinder 601. Although the anti-skid sheet 803 has a large friction with the inner wall of the square cylinder 601, it is still in a movable state when the screw rod 802 pushes the circular threaded tube and the square cylinder 601 to move, and does not affect the operation of the overall structure.

[0045] Specific as Fig.10 and Fig.11As shown, the flexible connection part 9 includes a multi-section electric push rod 901 fixed on the top of the transverse partition 3, a connecting needle 902 fixed on the top of the multi-section electric push rod 901, an adsorption sheet 903 fixedly connected to the top of the connecting needle 902 by adsorption, and a connecting rope 904 fixed to the bottom of the adsorption sheet 903. One end of the connecting rope 904 passes through the transverse partition 3 and the longitudinal partition frame 4 and is fixedly connected to the center position of the sliding bracket 10. An electromagnetic sheet is fixedly provided on the connecting end of the connecting needle 902 and the adsorption sheet 903, which can adsorb and fix the adsorption sheet 903 after being opened. A docking hole 606 for inserting the adsorption sheet 903 is provided in the threaded wire groove 603 of each wire barrel, and a magnet is provided in the docking hole 606. After the electromagnetic sheet is turned on, the magnetic force of the electromagnetic sheet is greater than the magnetic force of the magnet sheet, so that the electromagnetic sheet can suck the adsorption sheet 903 out of the docking hole 606. In actual use, the electromagnetic sheet adsorbs and fixes the adsorption sheet 903, and controls the position of the adsorption sheet 903 by the extension and retraction of the multi-stage electric push rod 901. After the screw rod 802 rotates to control the winding drum 602 to move to the desired position, the multi-stage electric push rod 901 extends to control the connection needle 902 to rise, and then inserts the adsorption sheet 903 into the docking hole 606. Then the electromagnetic sheet is closed, and the adsorption sheet 903 and one end of the connecting rope 904 are fixed in the winding drum 602 under the adsorption action of the magnet sheet. After that, turning on the first motor 701 can make the winding drum 602 rotate to realize the winding function.

[0046] Specific as Fig.10 As shown, the lifting partition 5 is composed of a sealing plate 501 that is close to the inner wall of the shell 2 and the inside of the longitudinal partition frame 4, and an elastic contraction connecting rod 502 fixed to the inner wall of the bottom of the shell 2. The top telescopic end of the elastic contraction connecting rod 502 is fixedly connected to the sealing plate 501. The elastic contraction connecting rod 502 maintains a contracted state under normal conditions, and pulls the sealing plate 501 to a low position, which can be used to pull down the high sealing plate 501 to complete the suction work, and can also be automatically reset after use, so as to facilitate the next drug administration work. A longitudinal connecting rod 16 is fixedly provided on the top of the sliding bracket 10, and the top of the longitudinal connecting rod 16 is fixedly connected to the bottom of the sealing plate 501 through a claw bracket 17. The connection structure is stable and has high strength.

A control switch 13 for controlling the volume change of the first cavity 14 and the second cavity 15 and adjusting the change rate is fixed on the outer wall of the shell 2, which is convenient for nursing staff to perform intelligent control. In actual use, an intelligent controller is equipped in the device, and each electrical component is intelligently controlled through the cooperation of the intelligent controller and the visual camera 18, so that the nursing staff only needs to press the corresponding control switch 13 to automatically adjust to the required mode. The visual camera 18 mainly confirms whether the docking hole 606 is aligned with the adsorption sheet 903, and connects after confirming the alignment.
