Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a drug delivery device for oncology. Background Art

[0002] Tumor is a genetic disease, but it is not hereditary. It refers to the situation where, under the influence of carcinogenic factors, the genes of cells change and the normal regulation of their growth is lost, leading to the abnormal proliferation of monoclonality and the formation of neoplasms. This neoplasm often forms a local mass, hence the name. Oncology is a secondary discipline in clinical medicine, which is divided into medical oncology, radiotherapy and surgical oncology. Medical oncology mainly engages in the medical treatment of various benign and malignant tumors.

[0003] When performing chemotherapy in the oncology department, the drug needs to be injected directly into the patient's body with the help of a syringe. Sometimes the injection is performed slowly and for a long time. After a long period of injection, the medical staff may not be able to continue to hold the syringe more steadily, causing the needle to tilt inside the needle eye, thereby causing drug extravasation and affecting the patient's treatment. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an oncology medication device in response to the above-mentioned defects, which can not only support the syringe when medical staff perform long-term injections, thereby reducing the workload of medical staff, but also is easy to install and disassemble, and has good adaptability.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a drug delivery device for oncology, including a syringe, the syringe including an injection tube and a push-pull rod movably connected to the injection tube, a support assembly being detachably connected to the outer wall of the injection tube, the support assembly including an elastic connecting block which is laterally sleeved on the injection tube and a support foot arranged on the lower side of the connecting block.

[0006] Compared with the existing technology, the beneficial effects of this solution are: before using the syringe for injection, the connecting block is first put onto the syringe laterally, and the syringe is supported by the support legs during injection, so as to avoid the situation where medical staff may not be able to hold the syringe more stably after a long period of injection; the connecting block is elastic and can adapt to syringes of different sizes, with a wide range of adaptability; and the support assembly is installed laterally on the syringe, which is convenient for removing it from the syringe after use for recycling, saving costs.

[0007] As a preferred embodiment of the present invention, both ends of the lower side of the connecting block are respectively provided with sliding grooves, each sliding groove is slidably fitted with a support leg, a first connecting hole is provided on the side wall of each sliding groove, and each support leg is provided with a plurality of second connecting holes spaced apart along its length direction, connecting belts are provided on the left and right sides of the connecting block, and a clamping block for clamping with the first connecting hole and the second connecting hole is provided on the inner side of the connecting belt.

[0008] The beneficial effects of this solution are as follows: before using the syringe for injection, first put the connecting block onto the injection tube, then determine the angle of the needle puncture, and then adjust the length of the support leg extending from the slide groove according to the angle that the syringe needs to maintain, so that when the support leg is attached to the patient's skin, the syringe located above the support leg remains in an inclined state. At this time, the inclination angle of the syringe is the same as the angle required for needle puncture, and can adapt to puncture angles of different requirements.

[0009] As a preferred embodiment of the present invention, a concave arc-shaped plate is provided at the lower portion of the two legs on the side away from each other.

[0010] Beneficial effects of this program:

[0011] (1) When the support leg is attached to the patient's skin, the curved plate provided on its lower side contacts the patient. Compared with setting the lower side of the support leg as a flat surface, the curved plate provided on the lower side of the support leg as a concave surface contacts the patient, which can make the support leg fit the patient's skin more closely, ensure the stability of the inclined placement of the syringe, and avoid causing discomfort to the patient.

[0012] (2) When the support leg is stored in the chute, the arc plate provided on the lower side of the support leg is located outside the chute. When the support leg is moved outward along the chute, the support leg can be moved outward by holding the arc plate, which is convenient to operate.

[0013] As a preferred embodiment of the present invention, a through hole is opened in the middle of the connecting block along its axial direction, and an opening connected to the through hole is provided on the upper side of the connecting block along its axial direction. The connecting block is laterally sleeved onto the injection tube through the opening.

[0014] The beneficial effects of this solution are as follows: when the connecting block is put on the injection tube, the connecting block is opened by holding the two curved plates, and then the injection tube is passed through the opening and inserted into the through hole, so that the connecting block can be put on the injection tube. By putting the connecting block on the injection tube laterally, it can not only adapt to injection tubes of different sizes and has a wide range of applications, but also facilitates the removal of the connecting block from the injection tube, facilitates the recycling of the connecting block, and saves costs.

[0015] As a preferred embodiment of the present invention, the connecting block is provided with a fixing portion for connecting to the injection tube, and the fixing portion includes connecting plates arranged on both sides of the upper surface of the connecting block in the vertical direction and a fixing block arranged on the top of each connecting plate. A flange is provided at the opening at the upper end of the injection tube, and a slot for engaging with the flange is provided on the side where the two fixing blocks are close to each other.

[0016] The beneficial effects of this solution are: after the connecting block is laterally sleeved onto the injection tube, the slot provided on the inner side of the fixing block is engaged with the flange provided on the upper end of the injection tube, and two fixing blocks are provided, which can ensure that the support assembly and the injection tube are more stably connected.

[0017] As a preferred embodiment of the present invention, the fixing block is located outside the connecting plate.

[0018] The beneficial effects of this solution are as follows: when using a syringe to inject liquid medicine into a patient's body, the medical staff's index finger and middle finger are respectively located on the lower side of the flange and abut against it, and the thumb is located on the upper side of the push-pull rod and abuts against it, and the push-pull rod is pushed downward by the thumb to inject the liquid medicine into the patient's body. The fixed block is set on the outside of the connecting plate. When performing the injection, the medical staff can place their index finger and middle finger respectively on the lower side of the two fixed blocks for leverage to avoid affecting the injection operation.
