Description

Technical Field

[0001] The invention relates to the technical field of medical injection, in particular to a multi-segment myeloma targeted therapeutic injection device. Background Art

[0002] Multiple myeloma (MM) is a malignant plasma cell disease. Its tumor cells originate from plasma cells in the bone marrow. Plasma cells are cells that develop from B lymphocytes to the final functional stage. Therefore, multiple myeloma can be classified as a type of B lymphocyte lymphoma. Currently, WHO classifies it as a type of B cell lymphoma, called plasma cell myeloma / plasmacytoma. It is characterized by abnormal proliferation of bone marrow plasma cells accompanied by excessive production of monoclonal immunoglobulins or light chains (M proteins). A very small number of patients may have non-secretory MM that does not produce M proteins. Multiple myeloma is often accompanied by multiple osteolytic lesions, hypercalcemia, anemia, and kidney damage. Since the production of normal immunoglobulins is suppressed, various bacterial infections are prone to occur. The incidence rate is estimated to be 2 to 3 / 100,000, with a male-to-female ratio of 1.6:1. Most patients are over 40 years old. Bortezomib can be combined with melphalan and prednisone (MP regimen) for the treatment of patients with multiple myeloma who have not been treated before and are not suitable for high-dose chemotherapy and bone marrow suppression, or used alone to treat patients with multiple myeloma who have relapsed after at least one or more treatments. This product can be used to treat patients with relapsed or refractory mantle cell lymphoma who have received at least one treatment before using this product. The safety and efficacy data for this indication come from a foreign single-arm Phase II clinical study of mantle cell lymphoma that relapsed after previous treatment. There is still a lack of clinical research data for the Chinese population.

[0003] However, the existing targeted treatment device has the problem that when injecting bortezomib, it is difficult to inject the drug solution in segments during the injection process, and the injection volume precision control is poor during manual injection, which affects the treatment effect. Therefore, in order to avoid the above technical problems, it is necessary to provide a targeted treatment device for multiple myeloma to overcome the above defects in the prior art.

[0004] Therefore, a multi-stage myeloma targeted treatment injection device is proposed, so that it can be adjusted according to the needs of injection of liquid medicine, and the absorption of liquid medicine can be accurately controlled through matching auxiliary devices, so as to reduce the burden of personnel in drawing liquid and accurately control the content of drawn liquid, so as to perform multi-stage injection according to needs. Summary of the invention

[0005] The present invention is intended to provide a multi-stage myeloma targeted treatment injection device to solve the problems of existing targeted treatment devices when injecting bortezomib, such as difficulty in injecting the drug solution in stages during the injection process, poor control of the injection volume during manual injection, and poor treatment effect.

[0006] To achieve the above object, the present invention provides the following technical solution: a multi-stage myeloma targeted therapy injection device, including a bracket, an elevating device is fixedly arranged above the bracket, a clamping device is fixedly arranged above the elevating device, a placing device is fixedly arranged below the bracket, a medicine bottle is movably arranged in the placing device, an injection tube is movably arranged between the elevating device and the clamping device, a push rod is movably arranged inside the injection tube, a needle head is clamped and arranged below the injection tube, and an adjusting device is threadedly adapted and arranged inside the push rod;

[0007] Clamping grooves are symmetrically opened above the injection tube;

[0008] A threaded groove is opened inside the push rod, push grooves are symmetrically opened on both sides of the push rod, scales are evenly arranged on the surfaces of both sides of the push rod, and a limiting rod is movably arranged on one side above the push rod;

[0009] The adjusting device includes an adjusting rod threadedly adapted and installed inside the push groove, a friction ring is fixedly arranged above the adjusting rod, an adjusting clamping ring is movably clamped below the adjusting rod, an adjusting plate is fixedly arranged below the adjusting clamping ring, and measuring plates are fixedly arranged at both ends of the adjusting plate.

[0010] The technical solution provided by the present invention is:

[0011] Through the mutual cooperation of the above structures, it is satisfied that the adjustment can be made according to the content of the liquid medicine to be aspirated, so as to perform multi-stage injection. When in use, rotate the push rod to make the measuring plate fit with the clamping groove, so that the measuring plate moves out of the inner wall of the injection tube. Rotate the adjusting rod to make the adjusting rod perform threaded rotation according to the threaded groove, so that the adjusting rod drives the adjusting clamping ring movably connected below to move up and down during the up and down movement, so that the movement of the adjusting clamping ring drives the adjusting plate and the measuring plate to move up and down. The adjusting plate moves up and down according to the push groove, and at the same time, the liquid medicine to be aspirated is accurately controlled according to the measuring plate and the scale. When the position of the measuring plate is adjusted, rotate the limiting rod to limit the position of the adjusting rod to prevent the adjusting rod from moving. Push the push rod to make the measuring plate enter the injection tube through the clamping groove, and then rotate the push rod body to make the measuring plate misaligned with the clamping groove to limit the highest extraction position of the push rod. When the measuring plate is at the top of the push rod, the liquid extraction amount is the smallest, and when the measuring plate is at the bottom of the push rod, the liquid extraction amount is the largest.

[0012] Further, the adjusting plate is movably adapted to the push groove, the measuring plate is movably in contact with the outer wall of the push rod, and the measuring plate is of the same size as the clamping groove.

One side of the lifting sliding plate is fixedly provided with a lifting positioning rod. The surface of the lifting positioning rod is threaded with a lifting bolt. The surface of the lifting bolt is movably provided with a lifting clamping rod.

[0016] Further, the clamping device includes a clamping plate fixedly installed above the lifting device. One side of the clamping plate is fixedly provided with a clamping groove. Above the clamping groove, a clamping telescopic rod is fixedly provided. Below the clamping telescopic rod, a clamping block is fixedly provided. The clamping block is movably adapted to the clamping groove. One side of the clamping block is fixedly provided with a first clamping rod.

One end of the placing telescopic rod is fixedly provided with a placing clamping plate. Above the support plate, a placing ring is fixedly provided. The placing clamping plate is movably adapted to the inner wall of the placing ring.

[0018] Further, a control device is fixedly installed above the clamping device.

[0019] The beneficial effects of this technical solution are as follows:

[0020] (1) In order to meet the requirement of accurately controlling the extraction of liquid according to needs, an adjusting device is threadedly and movably arranged on the inner wall of the push rod, so as to meet the adjustment and limit the push rod.

[0021] (2) In order to assist the syringe tube in extracting liquid and reduce the burden of manual liquid extraction, a lifting device is provided above the bracket, a clamping device is fixedly installed above the lifting device, and a placing device is fixedly installed below the bracket, so as to meet the need of assisting in the liquid extraction work;

[0022] During use, place the adjusted syringe in the middle of the lifting positioning rod and the lifting clamping rod. At the same time, place the upper part of the push rod between the first clamping rod and the second clamping rod. Rotate the lifting bolt to fix the lifting positioning rod and the lifting clamping rod, fix the syringe in the lifting device, and make the first clamping rod and the second clamping rod clamp and fix the upper part of the push rod. Then place the medicine bottle in the placement ring, use the control device to control the telescopic movement of the placement telescopic rod, make the placement telescopic rod push the placement clamping plate to move, and make the placement clamping plate clamp and fix the medicine bottle. Subsequently, use the control device to control the operation of the lifting motor, make the operation of the lifting motor drive the rotation of the lifting threaded rod, make the rotation of the lifting threaded rod drive the up and down movement of the lifting sliding plate, thereby driving the up and down movement of the syringe. During the movement of the syringe, the clamping telescopic rod operates simultaneously, making the clamping telescopic rod push the clamping block to move, making the clamping block push the first clamping rod and the second clamping rod to drive the push rod to move, making the push rod move to the lowest position inside the inner wall of the syringe, inserting the needle below the syringe into the medicine bottle.
