Abstract
Description
本發明係關於一種醫療器材,特別是指一種翼型針具保護套。The invention relates to a medical device, in particular to a wing-shaped needle protective cover.
醫療上經常使用各種具有兩個翼片的針具來進行抽血或輸液等作業,例如俗稱蝴蝶針或頭皮針的靜脈注射針、留置針、採血針等等,由於這兩個翼片能夠以拇指和食指捏持,讓護理人員在施打針具的時候,能夠更輕易的控制針頭的位置,因此特別適合使用在一些較細、不易注射、淺層的血管和施打部位。Medically, a variety of needles with two wings are often used for blood or infusion operations, such as intravenous needles, indwelling needles, and blood sampling needles commonly known as butterfly needles or scalp needles. The thumb and index finger pinch, so that the nursing staff can more easily control the position of the needle when applying the needle, so it is especially suitable for use in some thin, difficult to inject, shallow blood vessels and injection sites.
翼型針具使用完之後,護理人員必需要將原本的針蓋蓋上,使得沾有體液的針尖不會露出,才能將翼型針具丟棄,避免這些使用後的針具在廢棄物丟棄和處理的過程中扎到處理人員,造成疾病的傳染和處理人員的傷害。After the wing-shaped needle is used up, the nursing staff must cover the original needle cover so that the needle tip with body fluids will not be exposed before discarding the wing-shaped needle, so as to prevent these used needles from being discarded and discarded. In the process of treatment, the treatment personnel are stuck, causing the infection of the disease and the damage of the treatment personnel.
針蓋蓋上的時候,由於針蓋開口小,護理人員都必須要特別專注和謹慎,才能順利的蓋上針蓋。但是,醫療現場往往非常的忙碌,一旦護理人員分心或不注意,就很容易在蓋上針蓋的時候被針頭刺到,如此不僅造成護理人員的困擾,也會有疾病傳染的風險。When the needle cover is closed, due to the small opening of the needle cover, nursing staff must be particularly attentive and cautious to successfully cover the needle cover. However, the medical field is often very busy. Once the nursing staff is distracted or not paying attention, it is easy to be stabbed by the needle when the needle cover is covered. This will not only cause trouble for the nursing staff, but also risk of disease transmission.
有鑑於此,本發明提供一種翼型針具保護套,可以讓使用者以十分便利的方式將翼型針具收納在保護套當中。In view of this, the present invention provides a wing-shaped needle protective cover, which allows users to store the wing-shaped needle in the protective cover in a very convenient manner.

本發明藉由各個不同長度延伸部的落差,以及延伸部上主導斜邊的導引,讓翼型針具的翼片能夠順暢地被導引到容置槽中,進而將針頭收入翼型針具保護套內。The invention uses the drop of each extension part of different lengths and the guiding of the leading bevel on the extension part, so that the wings of the wing-shaped needle can be smoothly guided into the accommodating groove, and then the needle is received in the wing-shaped needle With a protective cover.
如第1、2圖所示,本發明所提供的翼型針具保護套10主要包含有一基部20、一第一延伸部30、一第二延伸部40以及一第三延伸部50。As shown in FIGS. 1 and 2, the winged needle
如第2圖至第5圖所示,基部20的整體結構形狀大致上如同環圈,其具有一環壁21以及由環壁21環繞圍構而成的一穿孔22,環壁21上設置有複數條凸肋23。第一延伸部30自環壁21延伸而出,其具有連接環壁21的一第一近端31以及遠離第一近端31的一第一遠端32,第一遠端32具有一第一主導斜邊33。第二延伸部40自環壁與第一延伸部30的同側朝第一延伸部30同向延伸而出,其具有連接環壁21的一第二近端41以及遠離第二近端41的一第二遠端42,該第二遠端42具有一第二主導斜邊43,且第一近端31與第二近端41之間形成一第一容置槽34。第三延伸部50自環壁21與第一延伸部30的同側朝第一延伸部30同向延伸而出,其具有連接環壁21的一第三近端51以及遠離第三近端51的一第三遠端52,該第三遠端52具有一第三主導斜邊53,且第二近端41與第三近端51之間形成一第二容置槽44,第三近端51與第一近端31之間形成一第三容置槽54。As shown in Figures 2 to 5, the overall structural shape of the
如第1圖至第5圖所示,於本發明的第一實施例中,第一延伸部30的長度大於第二延伸部40的長度,且第二延伸部40的長度大於第三延伸部50的長度。又第一主導斜邊33與第二主導斜邊43的傾斜方向相同,同時第二主導斜邊43與第三主導斜邊53的傾斜方向相同。說明中所描述的傾斜方向相同,是指因為長度逐漸減少而一同朝順時針或者逆時針產生斜面的方向與對比導斜邊相同。As shown in FIGS. 1 to 5, in the first embodiment of the present invention, the length of the
藉此,當翼形針具,例如蝴蝶針,要收入翼型針具保護套10內的時候,會有以下幾種情況。In this way, when a wing-shaped needle, such as a butterfly needle, is to be housed in the wing-shaped needle
首先,第一種情況如第6圖至第8圖所示,由於第一延伸部30最長,所以翼型針具上左、右翼片LW、RW中的右翼片RW先抵頂到第一主導斜邊33上,此時左翼片LW由於第三延伸部50較短而懸空,右翼片RW便順著第一主導斜邊33被導引到第一延伸部30與第二延伸部40之間,使得翼型針具產生轉動的狀況,同時右翼片RW則被帶動到第二延伸部40與第三延伸部50之間,最後左、右翼片LW、RW分別收入第二容置槽44和第一容置槽34當中。第二種情況是,針具上的左、右翼片LW、RW恰好閃過第一延伸部30,而使得右翼片RW會先抵頂到第二主導斜邊43上,此時左翼片LW仍然因為第三延伸部50較短而懸空,然後右翼片RW便會順著第二主導斜邊43被導引至第二延伸部40與第三延伸部50之間,同時左翼片LW則被導引到第三延伸部50與第一延伸部30之間,最後左、右翼片LW、RW分別收入第三容置槽54和第二容置槽44當中。第三種情況則是右翼片RW會先抵頂到第一主導斜邊33上,此時則是左翼片LW因為第三延伸部50較短而懸空,接著右翼片RW順著第一主導斜邊33被導引至第一延伸部30與第二延伸部40之間,此時左翼片LW則被導引到第三延伸部50與第一延伸部30之間,最後左、右翼片LW、RW分別收入第三容置槽54和第一容置槽34當中。First of all, the first case is as shown in Figs. 6 to 8. Since the
第四種情況則是左翼片LW會先抵頂到第一主導斜邊33上,此時右翼片RW由於第三延伸部50較短而懸空,繼續收針時左翼片LW便順著第一主導斜邊33被導引到第一延伸部30與第二延伸部40之間,同時右翼片RW則被帶動到第三延伸部50與第一延伸部30之間,最後左、右翼片LW、RW分別收入第一容置槽34和第三容置槽54當中。第五種情況是,針具上的左翼片LW抵頂到第二主導斜邊43之前,右翼片RW會先抵頂到第一主導斜邊33上,此時右翼片RW會被第一主導斜邊33導引到第一延伸部30與第二延伸部40之間,導引的過程中,左翼片LW會再接著被第二主導斜邊43導引至第二延伸部40與第三延伸部50之間,最後左、右翼片LW、RW分別收入第二容置槽44和第一容置槽34當中。第六種情況則是類同第五種狀況,左翼片LW抵頂到第三主導斜邊53之前,右翼片RW會先抵頂到第二主導斜邊43上,此時右翼片RW會被第二主導斜邊43導引到第二延伸部40與第三延伸部50之間,導引的過程中,左翼片LW會再接著被第三主導斜邊53導引至第二延伸部40與第三延伸部50之間,最後左、右翼片LW、RW會分別收入第三容置槽54和第二容置槽44當中。In the fourth case, the left wing piece LW will first hit the first
透過上述說明,本發明利用不同長度的第一延伸部30、第二延伸部40以及第三延伸部50所造成的落差,讓翼型針具的左、右翼片LW、RW能夠在第一主導斜邊33、第二主導斜邊43和第三主導斜邊53的導引下將翼片收入第一容置槽34、第二容置槽44或第三容置槽54中,進而將使用過的針頭收入翼型針具保護套10中。並且,不論是上述哪一個收真的情況下,以第8圖為例,針具的左、右翼片LW、RW恰好呈現約120度角,針具背面BS只有一個第二延伸部40,針具腹面AS則是有第一延伸部30和第三延伸部50的包圍,使得具有凸出管路的針具腹面AS被妥善的收在翼形針具10內,而不會造成針具腹面AS只有一個延伸部包圍使左、右翼片LW、RW撐開、撐壞延伸部的情況發生。在醫療現場使用時,本發明所提供的翼型針具保護套10只要拉動翼型針具下方的管線,便可以順暢的收入針具,不僅便利醫護人員操作,也能有效避免在忙碌的情況下,因為分心或不注意而無法妥善收針,進而造成醫護人員被針尖刺傷而感染的情況。Through the above description, the present invention utilizes the drop caused by the
另請參照第9圖至第11圖所示,於本發明的第二實施例中,該翼型針具保護套60的第一延伸部70的第一遠端72具有第一主導斜邊73和一第一次導斜邊75,第一次導斜邊75與第一主導斜邊73的傾斜方向相反,且第一主導斜邊73的長度等於第一次導斜邊75的長度,第一主導斜邊73與第一次導斜邊75交界處形成一第一圓角76。第二延伸部80的第二遠端82具有第二主導斜邊83和一第二次導斜邊85,第二次導斜邊85與第二主導斜邊83的傾斜方向相反,且第二主導斜邊83的長度等於第二次導斜邊85的長度,第二主導斜邊83與第二次導斜邊85交界處形成一第二圓角86。又第三延伸部90的第三遠端92具有第三主導斜邊93和一第三次導斜邊95,第三次導斜邊95與第三主導斜邊93的傾斜方向相反,且第三主導斜邊93的長度等於第三次導斜邊95的長度,第三主導斜邊93與第三次導斜邊95交界處形成一第三圓角96。說明中所描述的傾斜方向相反,是指因為長度逐漸減少而一同朝順時針或者逆時針產生斜面的方向與對比導斜邊不同。藉此,透過相對的主導斜邊和次導斜邊,第一延伸部70、第二延伸部80和第三延伸部90的遠端形成了對稱的凸尖構造,並且在主導斜邊與後一延伸部的次導斜邊之間(例如第一主導斜邊73與第二次導斜邊85之間)形成一個V形的凹口,使得翼型針具的左、右翼片LW、RW能夠更順利的收入翼型針具保護套60當中。Please also refer to FIGS. 9-11. In the second embodiment of the present invention, the first
然而,不同延伸部也可以混和單具有主導斜邊和兼具有主導斜邊和次導斜邊的構造。例如第12圖至第14圖所示,於本發明的第三實施例中,該翼型針具保護套100的第一延伸部110如同第一實施例,其第一遠端112僅具有第一主導斜邊113,但在第二延伸部120的第二遠端122具有第二主導斜邊123和與第二主導斜邊123傾斜方向相反的第二次導斜邊125,且第二主導斜邊123的長度大於第二次導斜邊125的長度,又第三延伸部130的第三遠端132具有第三主導斜邊133和第三次導斜邊135,第三次導斜邊135與第三主導斜邊133的傾斜方向相反,且第三主導斜邊133的長度大於第三次導斜邊135的長度。藉此,第一延伸部110具有單一導引斜邊,而第二延伸部120和第三延伸部130的遠端具有了不對稱的凸尖構造,這樣使得翼型針具能夠順利的收入翼型針具保護套100當中。However, different extensions can also be mixed with a structure having a leading hypotenuse and both a leading hypotenuse and a secondary hypotenuse. For example, as shown in Figures 12 to 14, in the third embodiment of the present invention, the
再請參照第15圖至第17圖所示,於本發明的第四實施例中,該翼型針具保護套140的第一延伸部150的第一遠端152具有第一主導斜邊153和第一次導斜邊155,第一主導斜邊153的長度大於第一次導斜邊155的長度。第二延伸部160的第二遠端162具有第二主導斜邊163和第二次導斜邊165,第二主導斜邊163的長度大於第二次導斜邊165的長度。又第三延伸部170的第三遠端172具有第三主導斜邊173和第三次導斜邊175,第三主導斜邊173的長度大於第三次導斜邊175的長度。其中,第一延伸部150的長度等於第二延伸部160的長度 ,且第二延伸部160的長度大於第三延伸部170的長度。藉此,第一延伸部150、第二延伸部160和第三延伸部170都有不對稱的凸尖結構,再加上長度相同的第一延伸部150和第二延伸部160,這樣使得翼型針具能夠順利的收入翼型針具保護套140當中。Please refer to FIGS. 15-17 again. In the fourth embodiment of the present invention, the first
除了上述三個延伸部之外,本發明也可以設計成四個延伸部的結構。例如第18圖與第19圖所示,於本發明的第五實施例中,該翼型針具保護套180具有第一延伸部190、第二延伸部200、第三延伸部210以及第四延伸部220,各延伸部均具有不對稱的凸尖結構。其中,第三近端211與第四近端221之間形成第三容置槽214,且第四近端221與第一近端191之間形成第四容置槽224;又第一延伸部190的長度大於第二延伸部200的長度,第三延伸部210的長度大於第四延伸部220的長度。In addition to the above three extensions, the present invention can also be designed into a structure of four extensions. For example, as shown in Figures 18 and 19, in the fifth embodiment of the present invention, the wing-shaped needle
