Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to a new type of venous puncture bloodletting needle with drainage and blood storage functions. Background Art
[0002] Venous bloodletting is a common treatment method in traditional Chinese medicine, and it belongs to the pricking method of three-edged needle puncture. Venous bloodletting can achieve the effects of dredging meridians, relieving heat and toxins, reducing swelling and relieving pain. It is suitable for various symptoms such as excess syndrome, heat syndrome, blood stasis, and pain. The three-edged needle is a medical needle used for puncturing and bleeding. It is mostly made of stainless steel. The needle handle is cylindrical, and the needle body to the needle tip is triangular cone-shaped. The tip of the blade is sharp. It is divided into large, medium, and small types. The clinical needle model can be appropriately selected according to different symptoms and the patient's physical strength.
[0003] At present, the existing bloodletting needles on the market have the following disadvantages:
[0004] Because the tip of the three-edged needle is relatively thick, and for venous bloodletting, especially deep venous bloodletting (such as Weizhong acupoint), the needle hole of the three-edged needle is relatively thick, causing greater damage to local tissues, which not only aggravates the patient's pain, but also easily leads to local tissue infection. Therefore, in view of the various disadvantages of three-edged needle bloodletting, doctors often use syringe needles with sharper tips and thinner needles, but syringe needle bloodletting has the following hygiene and safety risks:
[0005] (1) Low safety: The syringe needle has no scale, which makes it difficult for the operator to determine the depth of the needle, thus reducing the safety of bloodletting for patients.
[0006] (2) Increased risk of occupational exposure: When medical staff use a syringe needle for bloodletting, the syringe needle handle is directly facing the operator. The pressure of some deep veins is very high (such as popliteal vein bloodletting at the Weizhong point). At the moment of insertion, blood will spray out from the needle handle and can easily spray onto the operator's clothes, skin and mucous membranes. If the patient is a patient with a blood-related infectious disease, it can easily lead to unnecessary occupational exposure.
[0007] (3) Difficult to operate: Because some veins have high pressure, blood can easily spray onto the operator's clothing or skin mucosa. The operator often performs puncture at the patient's side, and the syringe needle handle is short. It is not convenient for the operator to hold the needle handle and apply force during puncture when wearing gloves, which increases the difficulty of operation.
[0008] (4) Not conducive to aseptic operation and increasing the risk of infection: During venous bloodletting, the amount of bleeding is often large and the patient needs to take off clothes. The operator usually asks the patient to stand on a plastic bag, a towel, or a newspaper to prevent blood from spraying (or flowing out) and contaminating clothes or the surrounding environment. Some operators even use trash cans or disposable paper cups to collect blood, which violates aseptic operation and is very likely to cause infection:
[0009] (5) The amount of bloodletting cannot be estimated: The amount of bloodletting depends on the site of bloodletting and the disease to be treated. Sometimes a few drops of bloodletting is enough, and sometimes several milliliters of blood are needed. At present, whether bloodletting is done with a three-edged needle or with a syringe needle instead of a three-edged needle, the amount of bloodletting cannot be accurately measured and can only be estimated by the operator. Therefore, the current bloodletting needle does not have this function. Utility Model Content
[0010] 1. Technical issues to be resolved
[0011] The technical problem solved by the utility model is to provide a new type of venous puncture bloodletting needle with drainage and blood storage functions, which is highly practical and can be simply operated and has a relatively simple structure.

[0012] (II) Technical solution
[0013] To achieve the above objectives, the utility model is implemented through the following technical solutions: a new type of venous puncture bloodletting needle with drainage and blood storage functions, including a needle, which can be designed in three sizes: large, medium and small. The surface of the needle is provided with an A scale line, the top of the needle is fixedly connected to a threaded barrel, and the internal thread of the threaded barrel is connected to a drainage component.
[0014] Optionally, the drainage assembly includes a drainage tube threadedly connected to the inside of the threaded barrel, the top of the drainage tube is connected to a drainage bag, and a B scale line is provided on one side of the drainage bag.

The anti-backflow structure of the drainage bag can prevent blood from flowing back, so that the bloodletting needle can collect the patient's blood and prevent blood from spraying onto the operator's clothes, skin and mucous membranes, reducing the exposure risk of medical staff.
[0022] 2. The new type of venous puncture bloodletting needle with drainage and blood storage functions enables the operator to control the depth of acupuncture through the setting of the A scale line on the needle surface, thereby improving the safety of bloodletting operations on patients.
[0023] 3. The new type of venous puncture bloodletting needle with drainage and blood storage functions, through the setting of the handle, makes it easy for medical staff to hold the needle handle and apply force during puncture, thus reducing the difficulty of operation.
[0024] 4. The new venous puncture bloodletting needle with drainage and blood storage functions achieves the purpose of enabling medical staff to determine the amount of blood to be let out by setting the B scale line on the surface of the drainage bag. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figures 1 to 4 The utility model provides a technical solution: a new type of venous puncture bloodletting needle with drainage and blood storage functions, comprising a needle 1, which can be designed in three sizes: large, medium and small. The surface of the needle 1 is provided with a scale line A. The setting of the scale line A on the surface of the needle 1 enables the operator to grasp the depth of acupuncture, thereby improving the safety of bloodletting for patients. The top of the needle 1 is fixedly connected with a threaded barrel 2, and the internal thread of the threaded barrel 2 is connected with a drainage component 3. Through the setting of the drainage component 3, when medical staff perform venous bloodletting therapy, the medical staff inserts the needle tip into the patient's vein, and the pressure inside the vein can drive the blood into the drainage tube 301 through the through hole inside the needle 1, and finally into the drainage bag 302, and the anti-backflow structure of the drainage bag 302 can prevent blood from backflowing, so that the bloodletting needle can collect the patient's blood, avoid blood spraying onto the operator's clothes, skin and mucous membranes, and reduce the exposure risk of medical staff;
[0032] The drainage assembly 3 includes a drainage tube 301 threadedly connected to the inside of the threaded tube 2, and a drainage bag 302 is connected to the top of the drainage tube 301. A B scale line is set on one side of the drainage bag 302. By setting the B scale line on the surface of the drainage bag 302, the purpose of enabling medical staff to determine the amount of blood let out is achieved;
[0033] The surface of the needle 1 is sleeved with a syringe 4, and the surface of the syringe 4 is fixedly connected with a handle 5. The setting of the handle 5 makes it easier for medical staff to hold the needle handle and apply force during puncture, thereby reducing the difficulty of operation.
[0034] A through hole is formed inside the needle 1, and a threaded tube 2 is connected to the top of the through hole.
[0035] The surface of the handle 5 is provided with a groove, and the surface of the groove is provided with an anti-slip pattern. The provision of the anti-slip pattern achieves the purpose of improving the stability of the medical staff holding the bloodletting needle;
