READ MORESide hole needle is a special injection needle with a hole on the side of the needle body. This design helps to reduce the pain during injection, improve the success rate of puncture, and quickly see the blood return, thereby improving the accuracy of puncture. The needle tip of the side hole needle is usually conical or pyramidal. It has the advantages of small wound and easy healing. It does not produce debris to the body tissue during injection, reduces complications, relieves the patient's pain, and does not block the needle when used for drug preparation or puncture, reducing pollution.
Side hole needles are mainly used for subcutaneous injection, intramuscular injection and intravascular injection. Its advantages are small wound and no wound epithelial debris will be brought into the body; the needle tip is conical or pyramidal, mainly used for drug preparation and puncture, and its advantages are sharp needle tip, and no bottle cork debris will be brought into the drug solution, no clogging of the needle and contamination of the drug. Compared with the existing bevel needle, the utility model has the advantages of small wound, easy healing, no debris on the body tissue during injection, can reduce complications, can relieve the pain of patients, and will not block the needle when used for preparing medicine or puncture, reducing pollution.
The working principle of the side hole needle is: the side hole is located on the side of the needle stem, which can effectively reduce the generation of debris when puncturing the bottle stopper, and prevent the particles that fall into the drug solution from entering the infusion channel along the drug solution.

READ MORESide hole needles are a common type of medical needle designed with one or more openings located on the side of the needle shaft near the tip. This structural feature distinguishes them from typical end-hole needles and serves specific clinical purposes. The side hole allows fluids, medications, or samples to flow through the needle while less trauma to tissues. This design can reduce the risk of clogging during procedures such as injections or fluid aspiration.
The side hole configuration provides an advantage in delivering medications or drawing fluids in delicate areas where direct end penetration might cause damage or discomfort. Additionally, side hole needles are often utilized in applications requiring a more controlled and dispersed flow of liquids. For example, in intravenous therapy or certain types of biopsies, the side hole needle can facilitate smoother fluid dynamics.
Materials used in side hole needles typically include stainless steel to ensure durability and maintain sharpness, while coatings may be applied to reduce friction for easier insertion. These needles vary in gauge size and length, catering to different clinical needs from veterinary use to human medicine. The manufacturing process ensures precision in the placement and size of side holes, which directly influences the needle’s performance.
The lateral hole needle shares similarities with the side hole needle but often refers to needles with holes positioned laterally along the shaft, sometimes multiple holes, rather than a single opening near the tip. This lateral hole arrangement allows for an even distribution of fluid flow across a broader area, which can be beneficial in specific medical or industrial applications.
Lateral hole needles are frequently used in procedures where a more diffuse delivery or extraction of fluids is required. For instance, in certain injection therapies or aspiration procedures, the lateral holes help prevent clogging and reduce pressure buildup by providing multiple pathways for fluid movement. This can also help in reducing tissue damage since the fluid pressure is dispersed over several openings instead of concentrated at a single point.
These needles are manufactured with strict quality control to ensure the size and placement of lateral holes meet the requirements for consistent performance. The needle’s gauge and length can be customized according to the intended use, allowing flexibility in various medical fields. In some specialized cases, lateral hole needles may be designed for veterinary use, allowing efficient treatment of animals with small discomfort.
Materials for lateral hole needles are typically selected to balance sharpness, strength, and corrosion resistance. Stainless steel remains a common choice due to its compatibility with medical standards. Additionally, surface treatments or coatings can be applied to improve needle insertion smoothness and reduce patient discomfort.
Vent hole needles are designed with small openings called vent holes, which are usually located near the needle tip or along the shaft. These vent holes serve to equalize pressure during fluid injection or aspiration processes, helping to prevent air locks or vacuum formation that could interfere with fluid flow.
One of the main purposes of vent hole needles is to facilitate smoother fluid dynamics in applications such as anesthesia, blood sampling, or certain diagnostic procedures. The vent hole allows air or fluid to enter or exit alongside the main fluid pathway, balancing pressure differences and preventing sudden surges or blockages.
Vent hole needles are particularly useful in scenarios where maintaining a continuous and controlled flow is critical. For example, in intravenous or intra-arterial procedures, vent holes can help reduce resistance when fluids are injected or withdrawn, thereby improving the overall safety and comfort of the process.
The design and placement of vent holes are carefully controlled during manufacturing to ensure they function correctly without compromising the needle’s structural integrity or sharpness. These needles come in various sizes and configurations to suit different medical requirements. The materials used typically provide a combination of strength and biocompatibility, such as stainless steel with smooth finishes.
In addition to medical uses, vent hole needles can sometimes be found in industrial or laboratory settings where precise fluid control is necessary. Their ability to balance pressure makes them useful for tasks requiring delicate handling of liquids or gases.
