Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide an anti-extravasation chemotherapy drug delivery device for medical oncology to solve the problem of the high degree of extravasation of chemotherapy drug delivery equipment in the medical oncology department, which is easy to flow due to intravenous injection. It is slow and causes blood return and drug liquid extravasation, which is very laborious for adjusting the pressure of the syringe and the care of the vascular rack, and requires high operating degrees for medical workers, and the stress response to drug injection when the tumor patient itself is in pain And the degree of rejection is large, so the blood pressure rises twice, which leads to the problem that the extravasation dosage affects the treatment operation

Embodiment 1

[0035] see Figure 1-Figure 8 , The present invention provides an anti-extravasation chemotherapy drug delivery device for medical oncology. 5. The annular valve dialysis barrel groove 2 is nested on the top of the dosing needle cap groove 3 and communicates with each other, and the gauze flaps 1 are provided with two and are respectively inserted into the left and right sides of the annular valve dialysis barrel groove 2. side, the drug delivery needle tube 5 is inserted under the bottom of the drug delivery needle cap groove 3 and the axis is collinear, the film tape 4 and the drug delivery needle tube 5 are in close contact with each other and are on the same arc surface. The annular valve dialysis barrel tank 2 is provided with a plunger slide frame 2A, an annular valve pressure relief groove 2B, and a wing bar syringe 2C. On both sides, the annular valve pressure relief groove 2B and the wing bar syringe 2C are nested into one body and are on the same vertical plane, and...

Embodiment 2

[0043] see Figure 1-Figure 8 , the present invention provides a kind of anti-extravasation chemotherapy drug delivery device for medical oncology, other aspects are the same as embodiment 1, the difference is:

[0044] see image 3 , the medication needle cap groove 3 is composed of a medication needle core 31 and a short cap groove 32, the medication needle core 31 is installed in the interior of the short cap groove 32, and the medication needle core 31 and the short cap groove 32 Inserted together and the axes are collinear, the drug delivery needle holder is formed in the short cap groove 32 through the drug delivery needle core 31 to receive the conduction effect.

[0045] see Image 6 , the administration needle core 31 is composed of a funnel groove 311 and a middle-through core tube 312, the funnel groove 311 is installed on the top of the middle-through core tube 312, and the funnel groove 311 is nested with the middle-through core tube 312 to form a It is integra...

Abstract

The invention discloses an anti-extravasation chemotherapy drug delivery device for medical oncology. The gauze wing plate is used to cooperate with the annular valve dialysis cylinder groove, and the plunger sliding frame and the annular valve pressure relief groove are used to form squeezed vein extraction to facilitate the operation of needle injection. The operation effect of fixed-release injection and drug delivery on the plate ensures the intravenous injection of chemotherapeutic drugs in medical oncology to avoid rupture of the blood vessel wall, and also improves the safety protection operation effect of slow entry, improves the uniformity of drug delivery and the efficiency of pressure regulation and unloading at the input end, guaranteeing The dosing saturation and quantification of the catheter-guided adjuvant therapy are high, and the patient's stimulation response is reduced to give people comfort.

Description

technical field [0001] The invention relates to an anti-extravasation chemotherapy drug delivery device for medical oncology, which belongs to the medical field. Background technique [0002] To prevent and control the spread of cancer cells in the medical oncology department, it is necessary to adapt the injection of chemotherapy drugs to medical electronic equipment to guide and control the disease, prolong the lifespan, improve the efficiency of patient treatment and the convenience of equipment-assisted drug delivery, and ensure medical care. The labor-saving operation effect of personnel, the shortcomings of the current technology public to be optimized are: [0003] Due to the high degree of extravasation of chemotherapy drug delivery equipment in the department of medical oncology, it is easy to cause blood return and drug solution extravasation due to the slow flow of intravenous injection. In the case of high requirements and the pain of tumor patients themselves, ...
