Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and more specifically to an anti-extravasation chemotherapy injector for oncology. Background Art

[0002] Oncology mainly provides conservative treatment for patients with malignant tumors. During the conservative treatment, chemotherapy drugs are accurately injected into the patient's vein through a corresponding injector, so that the drugs can effectively perform conservative chemotherapy on the tumors in the body according to the absorption of the vein. Therefore, the intervention of the injector can improve the injection effect of chemotherapy drugs; In summary, the inventor found that the existing injectors mainly have the following defects: since the current chemotherapy drugs for tumors are irritating, when the injector injects the drugs, extravasation may occur due to the shaking of the patient's body. As a result, when some drugs come into contact with the skin, it will cause skin damage and reduce the comprehensiveness of chemotherapy. Therefore, during drug administration, medical staff need to observe in real time, which will reduce the use intensity of the injector and increase the manual operation intensity. At the same time, after the injector is withdrawn from the patient's injection area, the remaining drugs in the syringe will drip again due to the pulling force during withdrawal. Affected by this phenomenon, the current injector cannot achieve a complete anti-extravasation effect. Summary of the Invention

[0011] As a further improvement of the present invention, the cartridge is provided with a connecting rod. The connecting rod is fixedly connected to three auxiliary discs and penetrates through the center of the cylinder cover at the upper end. The connecting rod carries the auxiliary discs into the mixing chamber of the airtight cylinder and communicates with the output disc below at the same time.

[0012] As a further improvement of the present invention, the connecting rod is fixedly cross-connected with the center of the cylinder cover. At the same time, there is a spacing between the three auxiliary discs carried by it. Thus, the mixing chamber inside the airtight cylinder is set in a vertical orientation, and the output disc is provided with a fixed output groove.

Rectangular sliders are provided on the left and right sides of the collecting module. The collecting groove is in a parallel concave shape and one end communicates with the assembling block. The lower end of the assembling block is provided with a clamping block.

[0018] Compared with the prior art, the present invention has the following beneficial effects: 1. After the administration structure of the present invention is further improved, the syringe needle can be stably positioned at the injection site of the patient through the trapezoidal rubber block and the medical fixing band, thus avoiding the loosening of the syringe needle and the leakage of the drug caused by the shaking of the patient's body. At the same time, the fitting contact of the rubber block can be used to replace the original solid fixing plate, preventing the pain caused by excessive squeezing of the patient's injection site. Furthermore, the rubber covering can effectively improve the stability of drug injection. Finally, after the drug injection is completed, when the syringe needle is withdrawn, the collecting module of the receiving body is inserted obliquely into the side of the rubber block. Therefore, the collecting groove of the collecting module can contact the lower end of the syringe needle. Therefore, when the syringe needle is withdrawn, the residual liquid medicine dripping out for the second time will be collected by the collecting module, completely avoiding the irritation caused by the direct contact of part of the liquid medicine dripping out for the second time with the patient's skin. Therefore, the use effect of the applicator can be further improved.

[0019] 2. After the collecting module of the present invention is further improved, the liquid medicine dripping out for the second time can be absorbed by the liquid absorbing pad installed inside, avoiding the difficult-to-handle situation caused by pooling in one place. At the same time, the liquid absorbing pad can be installed in the fixing block through a simple connecting body. Therefore, the fixing block can be stably embedded in the collecting module for overlapping use. Finally, the fixing block can be ejected from the bottom of the collecting module by the triangular part of the control module at the lower end. Therefore, the effect of non-contact disassembly of the liquid absorbing pad can be achieved, improving the convenience of replacing the liquid absorbing pad and the fixing block.

[0020] 3. After the further improvement of the cartridge of the present invention, various chemotherapy drugs can be gathered together through the mixing chamber inside the airtight cylinder, and then the connecting rod and the auxiliary disc on the cylinder cover are used for manual rotation to promote fusion, so as to improve the mixing uniformity between the drugs. Finally, after the drug injection is completed, the drug remaining on the inner wall of the airtight cylinder can be scraped upward by the edge of the auxiliary disc at the lowest end of the connecting rod, so as to improve the cleaning accuracy of the inner wall of the airtight cylinder and avoid the difficulty in cleaning caused by too small diameter size.

At the same time, the collection groove 554 combines with the assembly block 555 to receive the remaining part of the drug in the injection needle tube 54.

[0033] Among them, the collection module 552 is provided with a simple connection body 5522. The simple connection body 5522 is embedded in the surface part of a fixing block 5523, and the fixing block 5523 is fixedly connected to the lower end of a liquid absorption pad 5521 through the simple connection body 5522. At the same time, the liquid absorption pad 5521 and the fixing block 5523 overlap each other. The lower layer of the simple connection body 5522 communicates with a triangular part 5524, and a control module 5525 is fixed at the lower end of the triangular part 5524.

[0034] Among them, the simple connection body 5522 is arranged parallel to the upper end of the fixing block 5523, and the fixing block 5523 and the liquid absorption pad 5521 are both in the shape of "L".

[0035] Among them, the simple connector 5522 is provided with an insertion block 5221. The upper end of the insertion block 5221 is fixedly connected to the center of the lower end of the splicing ring 5222. A threaded groove 5223 is provided inside the splicing ring 5222 and is threadedly connected to a threaded block 5224. The upper end of the threaded block 5224 is welded with a puncture block 5225, and the liquid absorption pad 5521 is punctured and fixed by the puncture block 5225.

[0036] Among them, the insertion block 5221 is perpendicular to the splicing ring 5222. The diameter of the threaded groove 5223 of the splicing ring 5222 is adapted to the diameter of the threaded block 5224. The puncture block 5225 is in a solid form and in a triangular sharp form.

[0037] Among them, the medicine cartridge 1 is arranged vertically at the center of the upper end of the suspension block 2, and a rubber clamping ring is provided at the connection part between the lower end of the suspension block 2 and the guiding module 3. At the same time, the guiding module 3 is perpendicular to the hose 4.

[0038] Among them, the inner wall of the airtight tube 51 is provided with a rubber threaded wall. Furthermore, the rubber block 52 is trapezoidal in shape and is used in combination with a medical fixing band. The receiving body 55 is arranged obliquely on the side of the rubber block 52 and covers the lower end of the syringe needle 54 after being completely inserted.

[0039] Among them, a groove is provided at the center of the pulling block 551. Rectangular sliders 553 are provided on both the left and right sides of the collection module 552. The collection groove 554 is in a parallel concave form and one end communicates with the assembly block 555. A clamping block is provided at the lower end of the assembly block 555.

[0040] The specific functions and operation procedures of this embodiment: In the present invention, after adding the corresponding chemotherapeutic drug into the cartridge 1 of the anti-extravasation chemotherapy drug delivery device in the oncology department, it can be positioned in a specific pharmacy area through the hanging block 2. Then, the guiding module 3 at the lower end of the hanging block 2 can drain the drug to the drug delivery structure 5 through the hose 3, so that the drug delivery structure 5 can inject the drug into the patient's vein area through the syringe needle 54. When the syringe needle 54 is inserted into the patient's vein, it can improve the contact stability and injection airtightness through the contact layer 53 of the rubber block 52, and then use a medical fixing band to fix it in the injection site, so as to avoid the drug extravasation caused by the detachment of the syringe needle 54 due to the shaking of the patient's body. At the same time, the syringe needle 54 can be connected to the hose 4 through the rubber thread wall on the inner wall of the airtight tube 51, preventing the permeation waste generated when the liquid medicine flows, improving the stability of the liquid medicine circulation. Furthermore, after the liquid medicine injection is completed, the syringe needle 54 is withdrawn from the vein area, and the pull block 551 of the receiver 55 is immediately controlled, so that the collection module 552 can penetrate the side of the rubber block 52 in an inclined direction through the pull block 551. During the process, the slider 553 on the edge of the collection module 552 can play an auxiliary role. Then, the collection groove 554 can be located below the syringe needle 54. Subsequently, the assembly block 555 is inserted into the other end of the collection module 552, so as to seal the other end of the collection groove 554. Therefore, when the syringe needle 54 is withdrawn, the secondary dripping of the residual liquid medicine under the influence of force will fall into the collection groove 554, so that the residual part of the liquid medicine can be collected, avoiding the adverse reactions caused by the secondary dripping of part of the liquid medicine and contacting the patient's skin. Therefore, the use intensity of the drug delivery device can be effectively improved. Subsequently, the liquid absorption pad 5521 installed inside the collection module 552 can be attached to the fixing block 5523 through the simple connection body 5522, so that it can be stably installed in the collection groove 554 in the same "L" shape as the fixing block 5523 and matched with the assembly block 555. Therefore, the cooperation of the liquid absorption pad 5521 can absorb and process the liquid medicine, avoiding the outflow from the collection groove 554 area after the assembly block 555 is opened and affecting the subsequent processing stability. Finally, when the liquid absorption pad 5521 needs to be disassembled and replaced, the control module 5525 can drive the triangular part 5524 to eject the fixing block 5523 from the bottom of the collection module 552, so that the fixing block 5523 can be separated from the collection groove 554 area together with the liquid absorption pad 5521, achieving the process of avoiding hand contact for disassembly. Then, the simple connection body 5522 can be vertically installed on the fixing block 5523 through the insertion block 5221 of the splicing ring 5222, and then the splicing with the threaded block 5224 is completed through the threaded groove 5223. Subsequently, the triangular solid puncture block 5225 on the threaded block 5224 can puncture and fix the liquid absorption pad 5521, so as to achieve the effect of rapid disassembly and assembly, improving the efficiency of subsequent precise separation.

[0041] Example 2: Figures 6 to 7 As shown in: The present invention provides an anti-extravasation chemotherapy drug dispenser for oncology, The structure thereof includes that a connecting rod 15 is provided on the medicine cylinder 1. The connecting rod 15 is fixedly connected with three auxiliary discs 14 and penetrates through the center of the cylinder cover 16 at the upper end. The connecting rod 15 carries the auxiliary discs 14 into the mixing chamber 13 of the airtight cylinder 12 and is communicated with the output disc 11 at the lower end.

[0042] Among them, the connecting rod 15 is fixedly crossed with the center of the cylinder cover 16. At the same time, there is a spacing between the three auxiliary discs 14 carried by it. Thus, the mixing chamber 13 inside the airtight cylinder 12 is set in a vertical orientation, and the output disc 11 is provided with a fixed output groove.

[0043] Among them, the connecting rod 15 is provided with a restraint block 151. The restraint block 151 falls on the surface edge of the solid disc 152, and a rod body 153 is fixed in the center area of the solid disc 152. At the same time, three connecting layers 154 are set on the edge of the rod body 153. The rod body 153 completes the detachable connection with the three auxiliary discs 4 through the three connecting layers 154. The solid disc 152 is embedded in the surface part of the cylinder cover 16 through the restraint block 151.

[0044] Among them, four restraint blocks 151 are provided on the solid disc 152 in total, and the solid disc 152 and the rod body 153 form a "T" shape. Thus, the three connecting layers 154 of the rod body 153 are set in the upper, middle and lower three positions to adapt to the positions of the auxiliary discs 14.

[0045] The specific functions and operation procedures of this embodiment: In the present invention, the airtight cylinder 12 of the cartridge 1 can vertically output the liquid medicine in the mixing chamber 13 to the guiding module 3 through the output disc 11. Then, the mixing chamber 13 of the airtight cylinder 12 can collect a variety of chemotherapy drugs. Subsequently, when the cover cylinder 16 is embedded in the top of the airtight cylinder 12, the connecting rod 15 will vertically insert into the center of the mixing chamber 13. Furthermore, the three groups of auxiliary discs 14 carried thereon can perform fixed-point rotation inside the mixing chamber 13 through the rotation effect of the cover cylinder 16 on the airtight cylinder 12. Therefore, through the cooperation of the auxiliary discs 14, the uniform fusion effect of various drugs inside can be promoted. Then, the auxiliary discs 14 are provided with multiple holes, enabling the liquid medicine to flow stably downward. Finally, after the administration is completed, some liquid medicine will remain on the inner wall of the airtight cylinder 12. Therefore, when the cover cylinder 16 is separated from the top of the airtight cylinder 12, it can carry the connecting rod 15 and rise together. Subsequently, the auxiliary disc 14 at the bottom of the connecting rod 15 will scrape the inner wall of the airtight cylinder 12 using the circular shape of its edge, so that the substances remaining on the inner wall of the airtight cylinder 12 will be scraped upward and taken out, improving the cleaning accuracy of the airtight cylinder 12 and avoiding the difficult-to-clean situation caused by the small diameter. Subsequently, the solid disc 152 of the connecting rod 15 can be parallelly embedded in the upper layer of the cover cylinder 16 through the restraint block 151 to achieve the effect of mutual overlap. Then, using the vertical solid form of the rod body 153, the three threaded connection layers 154 can be set at the upper, middle, and lower positions, enabling the three threaded connection layers 154 to load the three auxiliary discs 14 one by one in parallel, so as to achieve the effect of easy disassembly and improve the mutual parallel effect of the three solid discs 152.
