Multifunctional combined syringe needle for underwater application in coral reef areas

Abstract

A multifunctional combined syringe needle for underwater applications in coral reef areas relates to syringes. The syringe needle is provided with a needle body, a rod body, a locking sleeve and a protective sleeve, the needle body is used for directly penetrating a living body for injecting a medicament; the rod body is provided with a scale line, and the rod body is used for contrast measurement, tapping sounding, direction indicating and body securing; the locking sleeve locks the needle body to the tip of the injection gun; the protective sleeve is for receiving and protecting the needle body exposed outside the rod body. The syringe needle can be matched with most types of syringe tips on the market and has strong versatility; the syringe needle is simple in structure and convenient to operate, can be used immediately without professional training, and is conducive to promotion and popularization of coral protection activities from professional divers to amateurs, thereby promoting the coral protection activities; and the needle can be stored, is easy to operate and easy to carry, does not impose an additional burden on diving activities, helps to protect the safety of divers,and helps to efficiently complete a task of injecting Acanthaster planci.

Description

technical field [0001] The invention relates to a syringe, in particular to a multifunctional combined syringe needle used underwater in coral reef areas. Background technique [0002] In recent years, coral reefs in the tropical coastal areas of the Pacific Ocean and Indian Ocean have been severely damaged. In addition to climate change, environmental pollution, and illegal fishing, another extremely important reason is the gnawing of corals by harmful organisms such as crown-of-thorns starfish. The crown-of-thorns starfish is large in size, with an adult radial diameter of 250-350mm, and the maximum is over 700mm. The main food is coral and the food intake is amazing. They eat the coral polyps on the surface of the coral and leave white coral skeletons. On average, a crown-of-thorns starfish can eat a day drop about 2m 2 corals; the crown-of-thorns starfish has a very strong reproductive ability. An adult crown-of-thorns starfish reproduces millions of eggs every year. On...

Problems solved by technology

In the course of diving practice, traditional syringe needles still have the following problems: (1) most of the needles are exposed without protective devices, it is very inconvenient for divers to hold syringes with needles, and there is a risk of hurting themselves or their diving partners; There are sharp thorns on the surface and are often hidden in the depths of coral reefs. The length of the needle generally needs to be greater than 10cm to inject the reagent into the starfish. The needles currently used are thin needles with a thickness of 1-2mm, and the needles are less than 5cm. Long, often not very effective in injecting reagents into starfish

Therefore, the traditional commonly used syringe needles are extremely inconvenient to carry, store, place, and use underwater, and cannot well adapt to the diving environment and the application requirements of removing crown-of-thorns starfish
