Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a disposable medical syringe. Background Art

[0002] A syringe is a common medical device. Its common structure generally includes an injection push-pull component, a syringe barrel, a needle, etc. This type of syringe is simple to make and easy to use. The syringe barrel can be made of plastic or glass, and usually has a scale indicating the volume of liquid in the syringe. Generally, 2 ml, 5 ml, 10 ml or 20 ml syringes are used, and 50 ml or 100 ml are occasionally used. A 1 ml syringe is used for intradermal injection.

[0003] When using the existing syringe, it is easy to cause the needle tube to stay on the patient's skin when injecting the patient, and the needle tube is loose, thereby causing great harm to the patient and psychological pressure. At the same time, when the existing syringe pushes the piston, it is more laborious, which may cause the needle tube to pierce deeper, thereby causing a certain degree of damage to the patient, which is more difficult to handle. Therefore, those skilled in the art provide a medical disposable syringe to solve the problems raised in the above background technology. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art, and to propose a medical disposable syringe. Compared with the existing syringes, the medical disposable syringe can stably fix the needle tube on the tube body through the internal thread and the external thread, so as to prevent the needle tube from staying on the patient's skin when the patient is injected to a certain extent, and can also prevent the needle tube from being loose when the staff unpacks the syringe, thereby causing the needle tube to fall, thereby increasing the cost consumption. At the same time, the syringe can be provided with a first connecting plate and a second connecting plate, so that when the staff inputs the drug solution into the patient, the connecting plate can fully exert force, thereby preventing the staff from causing the needle tube to be inserted too deep when exerting force, thereby causing a certain degree of damage to the patient.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A medical disposable syringe comprises a tube body, a first connecting column being threadedly connected to one side wall of the tube body, a first external thread being fixedly provided on the outer wall of the first connecting column, a fixing column being fixedly connected to a side of the first connecting column away from the tube body, a connecting rod being threadedly connected to a side of the fixing column away from the first connecting column, and a needle being fixedly connected to a side of the connecting rod away from the first fixing column.

[0007] Through the above technical solution, the device can prime the needle through the first external thread, thereby preventing the needle from staying on the skin when the staff is performing an infusion on the patient, thereby causing a certain degree of damage to the patient.

[0008] Further, both ends of the tube body away from the first connecting column are fixedly connected to the second connecting plates, one side of the two second connecting plates is slidably connected to the first connecting plate, one side of the two second connecting plates is fixedly provided with an illuminating lamp, and the outer wall of the tube body is provided with a scale;

[0009] Through the above technical solution, the first connecting plate and the second connecting plate can provide more force points for the staff to a certain extent, thereby preventing the needle from being inserted deeper and causing greater harm to the patient due to the use of greater force when performing infusion on the patient.

[0010] Furthermore, a groove is formed on a side of the tube body away from the first connecting column;

[0011] Through the above technical solution, the push rod can be easily inserted through the groove, so that the internal liquid can be output and input.

[0012] Furthermore, a first sealing block is slidably disposed inside the tube body, a piston is fixedly connected to one side wall of the first sealing block, second sealing blocks are fixedly connected to both sides of the piston, and a push rod is fixedly connected to one side of the piston away from the first sealing block;

[0013] Through the above technical solution, the first sealing block and the second sealing block arranged inside can prevent the internal liquid from stagnating when the patient is given an infusion, thereby causing more liquid medicine to be wasted and dripped, thereby increasing the cost of the liquid medicine.

[0014] Furthermore, a push plate is threadedly connected to one side of the push rod away from the piston, and a side wall of the push plate is paved with an anti-slip layer;

[0015] Through the above technical solution, the anti-slip layer can prevent the staff from slipping when performing infusion to a certain extent, which may cause the needle to be inserted deeper and cause greater harm to the patient.

[0016] Furthermore, a second connecting column is fixedly connected to a side of the push rod away from the piston, and a second external thread is provided on an outer wall of the second connecting column;

[0017] The above technical solution makes it easy to connect the push plate, thus preventing the push plate from becoming loose when placed for a long time, thereby preventing the syringe from being used normally.

[0018] Furthermore, an internal thread is provided on a side of the push plate away from the anti-slip layer;

[0019] Through the above technical solution, the push plate can be fixed by the set internal thread, thereby preventing the push plate from loosening and being damaged to a certain extent. When the push plate is damaged, it can be replaced, thereby reducing the cost consumption to a certain extent.

[0020] Furthermore, a through opening is formed on a side of the connecting rod away from the needle;

[0021] The above technical solution facilitates the delivery of the internal medicine liquid through the opening, thus preventing the phenomenon that the medicine liquid cannot be delivered.

[0022] The utility model has the following beneficial effects:

[0023] 1. Compared with the existing syringes, the medical disposable syringe proposed by the utility model can prevent the staff from leaving the needle on the patient's skin after the infusion is completed by the first external thread and the internal thread, thereby causing greater damage to the patient and causing more serious psychological harm to the patient, thereby causing more serious consequences.

[0024] 2. Compared with the existing syringes, the medical disposable syringe proposed by the utility model can increase the force points of the staff during infusion by setting the first connecting plate and the second connecting plate, thereby reducing the physical exertion of the staff, and at the same time can also prevent the needle from being inserted deeper due to greater force to a certain extent, thereby causing secondary damage to the patient.

[0025] 3. The medical disposable syringe proposed by the utility model has a simple structure and low operating difficulty. It can also reduce secondary damage to patients and has a high practical effect. BRIEF DESCRIPTION OF THE DRAWINGS
