Description
本發明關於使用後之注射針之安全保護裝置，更詳而言之，是一種專用於蝴蝶針的安全保護裝置，該安全保護裝置在蝴蝶針使用後將針體完全遮蔽，以免針體裸露。 The invention relates to a safety protection device for an injection needle after use, and more particularly to a safety protection device dedicated to a butterfly needle, which completely shields the needle body after the butterfly needle is used, so as to prevent the needle body from being exposed.
傳統的蝴蝶針，如第一圖，大致包括一針體1、與該針體1末端結合之針座2、以及設於該針座2上的蝶翼3。未使用的蝴蝶針通過一套設在針座2且完全遮蔽針體1的筒狀塑料蓋5使針體1保持無菌狀態。這種型式的蝴蝶針使用後，醫事人員通常會試圖將塑料蓋4套回該針座2上，以便遮蔽用過的針體1，然而，因為塑料蓋5的筒狀口徑小，筒狀口徑不容易對準針體1，以致於在套回的過程中發生針體1戳傷人手的問題。 The conventional butterfly needle, as shown in the first figure, generally comprises a needle body 1, a needle holder 2 coupled to the end of the needle body 1, and a butterfly wing 3 provided on the needle holder 2. The unused butterfly needle maintains the needle body 1 sterile by a set of cylindrical plastic covers 5 provided on the needle hub 2 and completely shielding the needle body 1. After the butterfly needle of this type is used, the medical staff usually tries to put the plastic cover 4 back on the needle holder 2 to shield the used needle body 1. However, because the cylindrical shape of the plastic cover 5 is small, the cylindrical diameter is small. It is not easy to align the needle body 1 so that the problem that the needle body 1 punctures the human hand occurs during the nesting process.
一些相關專利文獻提出解決上述問題的方案，例如中華民國專利M257833、M274966、M431708、M489646、M496494，這些專利文獻提供了套體、盒體、或蓋子等結構來遮蔽使用後之蝴蝶針的針體。M257833、M274966、M431708等案在套體的一側設一直通前端的長形開口，蝴蝶針的單翼或雙蝶翼對折後可通過該長形開口，將針體1收於該套體中。M489646提供了一個有蓋的盒體，盒體承置針體，蓋子將盒體封閉。這一類型的安全裝置體積稍微龐大，而且是穿套在與蝴蝶針相連的輸液管上，滑動和晃 動的問題會影響蝴蝶針的使用。M496494提供了一個蓋子套合在針座上，將蓋子往下壓則可以遮蔽整個針體，針體未使用前，蓋子是往上掀開的。然而，往上掀開的蓋子會遮蔽醫事人員使用蝴蝶針的視線並且對蝴蝶針的使用造成阻礙，而往下壓遮蔽針體的蓋子仍然可能受外力之影響而再度往外掀開，以致喪失了保護功能。 Some related patent documents propose solutions to the above problems, such as the Republic of China patents M257833, M274966, M431708, M489646, M496494, which provide a sleeve, a box, or a cover to shield the needle of the butterfly needle after use. . The M257833, M274966, M431708, etc. are provided with an elongated opening at the front end of the sleeve body, and the single or double butterfly wing of the butterfly needle can be folded into the sleeve body through the elongated opening, and the needle body 1 is received in the sleeve body. . M489646 provides a covered box that houses the needle body and the lid closes the box. This type of safety device is slightly bulky and is placed over the infusion tube connected to the butterfly needle, sliding and swaying. Moving problems can affect the use of butterfly needles. The M496494 provides a cover that fits over the needle holder. Pressing the cover down will shield the entire needle. The lid is opened upwards before the needle is used. However, the lid that is opened upwards will obscure the sight of the medical staff using the butterfly needle and hinder the use of the butterfly needle, and the cover that presses down the needle body may still be opened again by the external force, resulting in loss of Protective function.
本發明之目的是在提供一種蝴蝶針安全保護裝置，該安全保護裝置在蝴蝶針使用後將針體完全遮蔽，以免針體裸露。 It is an object of the present invention to provide a butterfly needle safety protection device that completely shields the needle body after use of the butterfly needle to prevent the needle body from being exposed.
