Description
本新型係有關一種輔助裝置,尤其是一種注射輔助裝置。可徒手拆裝該輔助裝置於一次性傳統注射器或筆型注射器(以下簡稱為“注射器”)上,幫助使用者方便、安全的進行皮下注射。更換新的一次性傳統注射器或為筆型注射器更換藥筒時,亦可徒手快速拆卸該輔助裝置,待更換完畢後,再裝上該輔助裝置重複使用。The present invention relates to an auxiliary device, and more particularly to an injection aid device. The auxiliary device can be disassembled and disassembled on a disposable conventional syringe or a pen-type syringe (hereinafter referred to as "syringe") to help the user to perform subcutaneous injection conveniently and safely. When replacing a new disposable conventional syringe or changing the cartridge for a pen-type syringe, the auxiliary device can be quickly disassembled by hand. After the replacement is completed, the auxiliary device is re-installed.
有某些疾病患者須長期居家自行或由家人幫助實施藥物注射,以治療疾病或維持健康。如第 I 型及部分第 II 型糖尿病患者需注射胰導素以維持血糖穩定。其中,部份病患使用比較便宜且提供較多彈性運用的一次性傳統注射器40(圖1),另外;有越來越多的病患使用筆型注射器10(圖1),因其便於攜帶,較不易引起注意且在外時方便注射,而且筆型注射器有預先填裝的胰島素藥筒,不需自行抽取胰島素而省時,並可一次或多次使用。Patients with certain diseases must be treated at home for a long time or with family help to treat the disease or maintain health. For example, type I and some type II diabetes patients need to be injected with trypsin to maintain blood sugar stability. Among them, some patients use disposable traditional syringes 40 (Fig. 1) that are relatively inexpensive and provide more flexibility. In addition, more and more patients use pen-type syringes 10 (Fig. 1) because they are easy to carry. It is less likely to attract attention and is convenient for injection when it is outside, and the pen-type syringe has a pre-filled insulin cartridge, which does not require self-extraction of insulin and saves time, and can be used one or more times.
如圖2所示,無論使用以上何者注射器,針頭套拔掉後,針頭均裸露安裝於注射器之頭端,注射器下壓同時,針頭率先接觸並刺入皮膚。過程中注射角度無法固定,須以目測,注射深度須以手部控制或更換不同長度針頭並使整支針頭沒入皮下方式為之;注射器本身並沒有提供可同時維持注射角度及控制注射深度的機能,尤其針對有肢體動作障礙、有手顫抖問題或注射其他不易施行部位如臀部或手臂上部外側時,更難正確、安全使用這些注射器。一般建議實施皮下注射以垂直注射區域(90度)下壓且深入皮下脂肪層為佳,避免刺入肌肉,實際注射深度因人而異,因為各人胖瘦不一。另外,進行皮下注射時注射位置的選擇很重要,盡可能避免在短期間內施打皮膚上的同一區域位置,造成該區域皮膚容易纖維化;使用前述現有注射器注射時,僅能裸視並憑記憶或利用其他輔助工具如放大鏡或標籤來幫助尋找標示位置,甚不方便。As shown in Fig. 2, no matter which of the above syringes is used, after the needle cover is removed, the needle is barely mounted on the tip end of the syringe, and the syringe is pressed and the needle is first contacted and penetrated into the skin. During the process, the injection angle cannot be fixed. It must be visually observed. The injection depth must be controlled by hand or replaced with different length needles and the whole needle is not subcutaneous. The syringe itself does not provide the ability to maintain the injection angle and control the injection depth. Functionality, especially for those with physical movement disorders, hand tremor problems, or other difficult-to-apply areas such as the buttocks or the upper part of the upper arm, it is more difficult to use these syringes correctly and safely. It is generally recommended to perform subcutaneous injections in a vertical injection area (90 degrees) and deep into the subcutaneous fat layer to avoid penetration into the muscles. The actual injection depth varies from person to person, because each person is fat and thin. In addition, the selection of the injection site when subcutaneous injection is important, as far as possible to avoid the application of the same area on the skin in a short period of time, resulting in easy skin fibrosis in the area; when using the aforementioned syringe injection, only naked and It is not convenient to remember or use other auxiliary tools such as magnifiers or labels to help find the location.
皮下注射完畢要拆卸注射針頭回收又是另外一個問題,為了避免使用過的針頭扎到病患本身或幫助實施注射者或無辜的第三方,往往會有先用針頭套進行回套再取下針頭的動作,過程中因為不小心或肢體不協調或視力不良而被刺傷的事情時有所聞,有時更會造成無法彌補的傷害。習用注射器針頭用畢後,以針頭套回套時沒有任何導引機制,由於針頭直接裸露在外,過程中手指很容易被刺傷。It is another problem to disassemble the injection needle after the subcutaneous injection. In order to prevent the used needle from sticking to the patient itself or to help the injecting or innocent third party, it is often necessary to first use the needle cover to remove the needle and then remove the needle. The movements, which are stabbed in the process because of carelessness or disharmony or poor eyesight, sometimes cause irreparable damage. After the syringe needle is used, there is no guiding mechanism when the needle sleeve is used to return the sleeve. Since the needle is directly exposed, the finger is easily stabbed during the process.
另有一種常發生的情況是患者有時須在夜間或戶外燈光微弱或沒有光源的環境下施行注射。某些視力缺損病人或老人家,平日即使在白天施行注射已經深感吃力,更何況在黑暗之中;前述習用之注射器,自體無提供光源之功能,在黑暗中常常無法找到注射位置,有時會扎到靜脈血管,造成出血。 基於以上使用現有注射器進行皮下注射會有的種種問題,包括無法維持垂直注射角度、容易晃動、無法控制注射深度、容易被針頭刺傷、注射區域不易辨識及無自體光源。需要提供一種經濟簡單的解決方案,來幫助病患克服心理障礙並解決這些問題。Another common occurrence is that patients sometimes have to perform an injection at night or in an environment with little or no light. Some patients with visual impairment or the elderly have been struggling even in the daytime, even in the dark; the aforementioned syringes do not provide the function of a light source, and often cannot find the injection position in the dark. Sometimes Will puncture into the veins, causing bleeding. Various problems due to the above-described subcutaneous injection using an existing syringe include the inability to maintain a vertical injection angle, easy to shake, inability to control the depth of the injection, easy to be stabbed by the needle, difficulty in identifying the injection area, and no self-light source. There is a need to provide an economical and simple solution to help patients overcome psychological barriers and solve these problems.
本創作利用的技術手段是提供一種可拆裝式的注射輔助裝置,徒手拆裝於前述習用注射器上重複使用,幫助使用者更方便、安全的進行皮下注射。該注射輔助裝置除了能維持垂直注射角度、降低手部晃動、放大注射區域、預防針頭刺傷及控制注射深度以外,更可提供照明讓使用者能在燈光微弱甚至沒有光源的環境下施行注射。該注射輔助裝置包括有一基座、一夾持機構、一注射導套、一光源模組、一深度調整件及一電力供應單元;The technical means utilized in the present invention is to provide a detachable injection aid device, which can be repeatedly disassembled and used on the conventional syringe to help the user to perform subcutaneous injection more conveniently and safely. In addition to maintaining a vertical injection angle, reducing hand sway, amplifying the injection area, preventing needle stick injuries, and controlling the depth of injection, the injection aid can provide illumination for the user to perform an injection in an environment with little or no light. The injection aid includes a base, a clamping mechanism, an injection guide sleeve, a light source module, a depth adjustment member and a power supply unit;
其中,基座容置該輔助裝置之所有零件,並提供一第一空間給注射器,該第一空間與注射器同軸,第一空間接近注射區域的一端為基座的近端,遠離注射區域的一端為基座的遠端。基座上設有一機制能固定注射導套於一適當位置,讓注射器的針頭安裝部裸露出來方便使用者安裝或更換針頭,使該注射器不會因為該輔助裝置的存在而不易更換針頭。基座遮蔽藥管承載室的部分可為透明或至少設有一開放空間,藉以觀察該注射器藥管內藥劑的剩餘量。Wherein, the susceptor houses all the components of the auxiliary device and provides a first space for the syringe, the first space is coaxial with the syringe, and the first space is close to the injection region and the end of the injection region is the proximal end of the pedestal, away from the end of the injection region. Is the distal end of the base. A mechanism is provided on the base to fix the injection guide sleeve in a proper position, so that the needle mounting portion of the syringe is exposed to facilitate the user to install or replace the needle so that the syringe does not easily change the needle due to the presence of the auxiliary device. The portion of the base shielding cartridge carrying chamber may be transparent or at least provided with an open space for viewing the remaining amount of medicament in the syringe cartridge.
夾持機構位於基座的遠端並與基座連接,用以徒手拆裝該輔助裝置於注射器上。該夾持機構包含有一夾套及一套筒,夾套為一受力時內徑會收縮的元件,夾套的內徑需略大於注射器被夾持區域的外徑;夾套的內徑可配合注射器的外徑而改變,不同管徑的注射器可配合更換不同內徑的夾套。夾套被夾置於套筒與基座之間,套筒與基座上下相連接並鎖緊的同時會壓迫夾套使其變形內縮,而夾住置於其中的注射器,進而固定注射輔助裝置於該注射器之上。完全不需借用工具,徒手即可利用該夾持機構迅速拆裝該輔助裝置於前述之注射器上。尤其針對可多次使用的筆型注射器,該輔助裝置不需每次注射後拆下,可連續使用直到該筆型注射器上的藥管使用完畢並更換新的藥管為止。即使要更換新的注射器,亦可重複使用原有注射輔助裝置。The clamping mechanism is located at the distal end of the base and connected to the base for dismounting the auxiliary device on the syringe by hand. The clamping mechanism comprises a jacket and a sleeve, wherein the jacket is an element whose inner diameter contracts when the force is applied, and the inner diameter of the jacket needs to be slightly larger than the outer diameter of the clamped region of the syringe; the inner diameter of the jacket can be With the outer diameter of the syringe changed, syringes of different diameters can be used to replace the jackets with different inner diameters. The jacket is sandwiched between the sleeve and the base, and the sleeve is connected to the upper and lower sides of the base and locked, and the sleeve is pressed and deformed and contracted, and the syringe placed therein is clamped, thereby fixing the injection aid. The device is placed above the syringe. The auxiliary mechanism can be quickly disassembled and detached from the aforementioned syringe by using the clamping mechanism without any need of borrowing tools. Especially for pen-type syringes that can be used multiple times, the auxiliary device does not need to be removed after each injection, and can be used continuously until the medicine tube on the pen-type syringe is used and a new medicine tube is replaced. The original injection aid can be reused even if a new syringe is to be replaced.
注射導套與第一空間同軸,且滑動地與基座連接,並包含該注射器於內;有相對的近端和遠端,接近注射區域的一端為近端,遠離注射區域的一端為遠端;注射導套的近端有一導引空間,該導引空間與注射針頭套上的一特徵尺寸配合接觸,當注射完畢時,用以引導針頭套回套,以安全地拆卸使用後的針頭,過程中注射針頭完全封閉在注射導套及針頭套之內,避免使用者被注射針頭扎傷。注射導套的遠端,有一彈性元件置於其後並位於基座之中,因受壓產生一彈力,該彈力持續作用於注射導套上,使其突出於注射器注射針頭的尖端。下壓注射時,注射導套因受到皮膚擠壓,會沿著該注射器以相反於注射方向移動,更進一步壓縮彈性元件;注射完畢時,下壓力量移除,注射導套受其遠端彈性元件的反彈力量作用,會沿著該注射器反向退回。只要使該注射導套近端平面在下壓注射過程中一直與注射區域皮膚貼平,即可保持該注射器與注射位置垂直接觸。該注射導套的功用,乃針對有手顫抖問題的使用者,在針頭接觸並插入皮膚前,提供較大面積之穩定支撐以避免手部晃動以利注射,過程中能幫助注射器保持垂直(90度)之注射角度,直到注射完成。對於有針頭恐懼症的使用者,由於針頭非直接裸露在外,於注射全程皆隱藏於該注射導套之內,故可降低其恐懼之程度,同時可保護施行注射者免於被針頭扎傷。該注射導套需具有透視性及放大功能,目的是為可視並放大注射區位,方便尋找適當注射位置及避免扎到靜脈血管造成出血。The injection guide sleeve is coaxial with the first space and is slidably coupled to the base and includes the syringe therein; has opposite proximal and distal ends, one end near the injection area is proximal, and one end remote from the injection area is distal The proximal end of the injection guide sleeve has a guiding space, and the guiding space is in contact with a characteristic dimension on the injection needle sleeve, and when the injection is completed, the needle sleeve is used to guide the needle sleeve to safely disassemble the used needle. During the process, the injection needle is completely enclosed within the injection guide sleeve and the needle cover to prevent the user from being stabbed by the injection needle. At the distal end of the injection guide sleeve, an elastic member is placed behind it and located in the base, and an elastic force is generated by the pressure, and the elastic force continues to act on the injection guide sleeve so as to protrude from the tip end of the syringe injection needle. When the injection is pressed, the injection guide sleeve is pressed by the skin and moves along the syringe in the opposite direction to the injection direction to further compress the elastic member; when the injection is completed, the amount of depression is removed, and the injection guide sleeve is elasticized by the distal end thereof. The rebounding force of the component will reverse back along the syringe. As long as the proximal plane of the injection guide is level with the skin of the injection area during the compression injection process, the syringe can be kept in vertical contact with the injection site. The function of the injection guide sleeve is for the user with hand tremor problem, providing a large area of stable support before the needle contacts and inserts into the skin to avoid hand shaking for injection, which helps the syringe to remain vertical (90 Injection angle until the injection is completed. For users with needle phobia, because the needle is not directly exposed, it is hidden inside the injection guide sleeve during the whole injection process, so it can reduce the degree of fear and protect the injecting person from needle stick injury. The injection guide sleeve needs to have a perspective and magnification function, in order to visualize and enlarge the injection position, so as to conveniently find the proper injection position and avoid bleeding caused by tying the vein to the vein.
光源模組設置於基座的近端且朝向注射區域,由一個照明光電板及複數個照明元件所構成,該複數個照明元件沿著注射導套的周圍均勻分佈於照明光電板上,經由電性連接方式與電力供應單元連接,在注射時由注射區域上方提供照明;該電力供應單元內設有一開關機制,當使用者需要使用照明時才啟動光源,達到節約用電的目的。藉由該輔助裝置上設置的光源模組提供照明,使用者可在夜間或沒有光源的場所順利進行注射。使用者可利用該光源準備注射所需相關用品、尋找並決定注射位置、調整注射劑量、清潔消毒注射區域後進行注射。注射完畢後方便收拾善後,使用過後的針頭可立即安全的收藏於容器內,避免被針頭刺傷。The light source module is disposed at a proximal end of the base and faces the injection area, and is composed of an illumination photoelectric plate and a plurality of illumination elements. The plurality of illumination elements are evenly distributed on the illumination photoelectric plate along the periphery of the injection guide sleeve, and are electrically connected. The connection mode is connected with the power supply unit, and the illumination is provided above the injection area during the injection; the power supply unit is provided with a switch mechanism to activate the light source when the user needs to use the illumination to save power. By providing illumination by the light source module provided on the auxiliary device, the user can smoothly inject at night or in a place without a light source. The user can use the light source to prepare the relevant articles for injection, find and determine the injection position, adjust the injection dose, and clean and disinfect the injection area for injection. After the injection is completed, it is easy to clean up. After use, the needle can be safely stored in the container immediately to avoid being stabbed by the needle.
深度調整件設置於基座上,沿注射器的方向設置有至少一個定位位置給注射導套,用來阻擋注射導套以控制注射深度,注射深度的選擇視接受注射者身材的胖瘦與注射部位的不同來決定。注射深度是藉由限制注射導套的停泊位置來決定,在下壓注射時,注射導套因為受到皮膚擠壓,會沿著遠離注射區域的一方運動,進而使針頭露出注射導套並朝向注射區域的一方運動而刺入皮膚內,針頭露出多少,皮膚就被刺入多少。深度調整件提供注射深度設定功能,使用者可使用同一規格長度針頭,藉由注射深度調整,進行身體不同部位注射,不需更換不同長短針頭。The depth adjusting member is disposed on the base, and at least one positioning position is provided in the direction of the syringe to the injection guide sleeve for blocking the injection guide sleeve to control the injection depth. The selection of the injection depth depends on the fatness and the injection site of the injecting body. The difference is decided. The depth of injection is determined by limiting the position of the injection guide sleeve. When the injection is pressed, the injection guide sleeve is moved along the side away from the injection area, and the needle is exposed to the injection guide sleeve and toward the injection area. One of the movements penetrates into the skin, how much the needle is exposed, and how much the skin is pierced. The depth adjustment component provides the injection depth setting function. The user can use the same length of the needle to inject different parts of the body by adjusting the injection depth without changing the different lengths of needles.
本創作乃集合遮蔽針頭、區域放大可視、垂直穩定注射、注射深度設定、夜間照明等功能於一身,且可徒手拆裝於現有注射器上重複使用的注射輔助裝置,不僅可以解決目前使用習用注射器進行皮下注射的所有前述問題,並提供了更多的實用機能,使用者勿須更換注射器或使用其他任何的輔助工具,不論白天、夜晚、室內或戶外,皆可安全、正確、方便地進行皮下注射。The creation is a combination of a needle, a magnified area, a vertical stable injection, an injection depth setting, a nighttime illumination, etc., and can be easily disassembled and used on an existing syringe to re-use the injection aid, which can not only solve the current use of a conventional syringe. All the aforementioned problems of subcutaneous injection, and provide more practical functions, users do not need to change the syringe or use any other auxiliary tools, whether it is day, night, indoor or outdoor, safe, correct and convenient subcutaneous injection .
為能詳細瞭解本新型的技術特徵及實用功效,並可依照說明書的內容來實現,玆進一步以如圖式所示的較佳實施例,詳細說明如后:本創作係提供一種可拆裝式的注射輔助裝置,可重複使用於目前一般的一次性傳統注射器或筆型注射器等皮下注射裝置上。於本實施例中,該皮下注射裝置係為筆型注射器。In order to understand the technical features and practical effects of the present invention in detail, and in accordance with the contents of the specification, the following further describes the preferred embodiment as illustrated in the following: the present invention provides a detachable type. The injection aid can be reused on a subcutaneous injection device such as a conventional disposable conventional syringe or a pen-type syringe. In the present embodiment, the hypodermic injection device is a pen type syringe.
如圖3所示,該注射輔助裝置包括有一基座100、一夾持機構200、一注射導套300、一光源模組400、一深度調整件500及一電力供應單元600。如圖4與圖6所示,夾持機構200由一套筒210、一夾套220與基座100接合而組成;其中,基座100的遠端有螺紋部100h,與套筒210的螺紋部210c連接,夾套220藉由圓錐面220a、220b分別與套筒210的圓錐面210a及基座100的圓錐面100a貼合而夾置於他們之間;夾套220有一開槽220c,可提供變形空間,當基座100的螺紋部100h與套筒210的螺紋部210c接合並沿著筆型注射器10的軸向鎖緊時,基座100與套筒210的圓錐面會沿軸向,面對面的逼近夾套220之兩個圓錐面220a、220b且同時擠壓夾套220迫使其沿徑向變形收縮,該注射輔助裝置因而被束緊在筆型注射器上。藉由這個夾持機制,使用者不需藉由工具,可迅速的拆裝該注射輔助裝置於注射器上並重複使用。基座100上設有一開槽100c,除了提供引導及固定注射導套300的機制外,亦可用以觀察基座100內的筆型注射器10,檢查其藥管承載室10c內的藥管10d是否還有藥劑。As shown in FIG. 3, the injection assisting device includes a base 100, a clamping mechanism 200, an injection guide sleeve 300, a light source module 400, a depth adjustment member 500, and a power supply unit 600. As shown in FIG. 4 and FIG. 6, the clamping mechanism 200 is composed of a sleeve 210 and a jacket 220 engaged with the base 100. The distal end of the base 100 has a threaded portion 100h and a thread of the sleeve 210. The portion 210c is connected, and the jacket 220 is sandwiched between the conical surface 210a of the sleeve 210 and the conical surface 100a of the base 100 by the conical surfaces 220a and 220b, respectively; the jacket 220 has a slot 220c. A deformation space is provided. When the threaded portion 100h of the base 100 engages with the threaded portion 210c of the sleeve 210 and is locked along the axial direction of the pen injector 10, the conical surfaces of the base 100 and the sleeve 210 are axially facing each other. Approaching the two conical faces 220a, 220b of the jacket 220 and simultaneously squeezing the collet 220 forces it to contract in the radial direction, the injection aid is thus tightened onto the pen injector. With this clamping mechanism, the user can quickly disassemble the injection aid on the syringe and reuse it without using a tool. The base 100 is provided with a slot 100c. In addition to providing a mechanism for guiding and fixing the injection guide sleeve 300, it can also be used to observe the pen type syringe 10 in the base 100, and check whether the medicine tube 10d in the medicine tube carrying chamber 10c is There are also potions.
如圖5所示,注射導套300的遠端附近固定有一插銷310,插銷310受力作用會沿著基座100上之溝槽100c的軌跡,在起始點100d與終止點100f之間移動,同時也限制了注射導套300的移動。 如圖4所示,注射導套300的遠端有一階梯承接部300a用來承接一彈性元件320,並使該彈性元件320與注射導套300保持同軸心;彈性元件320的另一端由一固定環330來承接,固定環330亦與注射導套300同軸心;固定環330的背面330a與基座100內部之一肩部100e緊密貼合,注射導套300之階梯承接部300a與固定環330形成的容置空間比彈性元件320的自由長度為小,因此壓縮了彈性元件320使其產生彈力,該彈力在注射下壓前後會持續作用在注射導套300之上。 (圖4、5)注射下壓前,彈性元件320之彈力作用於注射導套300上使其沿注射方向A移動,直到位於其上之插銷310被擋在起始點100d而停止,此時,注射導套300的近端平面300b會突出於注射器注射針頭30a的尖端,可保護使用者免於被針頭刺傷;注射下壓時,注射導套300會比注射針頭30a先接觸皮膚並提供一較大面積(300b)之穩定支撐;繼續下壓時,注射導套300因受到皮膚擠壓,會沿著相反於注射方向A的方向移動,同時插銷310也會跟著移動,進而壓縮彈性元件320而產生更大的彈力,該彈力會作用於注射導套300上使其近端平面300b貼緊皮膚,以支撐手部避免其晃動;當注射導套300退縮使注射針頭30a尖端突出於注射導套300近端平面300b時,注射針頭30a開始刺入皮膚。如圖9所示,要安裝注射針頭組30時,以手指撥動插銷310帶動注射導套300沿著基座100上溝槽100c往後縮,直到最後,溝槽100c的末端軌跡會由軸向改為徑向,插銷310最後會停泊在終止點100f,目的是為了使注射導套300保持在這個高度位置,此時注射器近端的針頭安裝部10a會完全裸露出來,方便病患安裝注射針頭組30,安裝完成後,再撥動插銷310使其歸位回到起始點100d。 如圖10所示,注射導套300的近端有一導引空間300c,該導引空間300c與注射針頭套30b上的一特徵尺寸30c配合接觸,當注射完畢時,用以引導針頭套30b回套,以拆卸針頭30a,過程中注射針頭30a完全封閉在注射導套300及針頭套30b之內,避免使用者被注射針頭30a扎傷。另外,該注射導套300具有透視性及放大功能,目的是為可視並放大注射區位,避免扎到血管造成出血。As shown in FIG. 5, a pin 310 is fixed near the distal end of the injection guide sleeve 300, and the force of the pin 310 is moved along the trajectory of the groove 100c on the base 100 to move between the starting point 100d and the end point 100f. At the same time, the movement of the injection guide sleeve 300 is also limited. As shown in FIG. 4, the distal end of the injection guide sleeve 300 has a step receiving portion 300a for receiving an elastic member 320, and the elastic member 320 is kept concentric with the injection guide sleeve 300; the other end of the elastic member 320 is fixed by a fixing. The ring 330 is received by the ring 330. The fixing ring 330 is also concentric with the injection guide sleeve 300. The back surface 330a of the fixing ring 330 is in close contact with one of the shoulders 100e of the base 100. The step receiving portion 300a and the fixing ring 330 of the injection guide sleeve 300 are closely attached. The accommodating space formed is smaller than the free length of the elastic member 320, and thus the elastic member 320 is compressed to generate an elastic force which continues to act on the injection guide sleeve 300 before and after the injection depression. (Fig. 4, 5) Before the injection is pressed, the elastic force of the elastic member 320 acts on the injection guide sleeve 300 to move in the injection direction A until the latch 310 located thereon is stopped at the starting point 100d, at this time. The proximal plane 300b of the injection guide sleeve 300 protrudes from the tip end of the syringe injection needle 30a to protect the user from being stabbed by the needle; when the injection is pressed, the injection guide sleeve 300 contacts the skin of the injection needle 30a first and provides a A stable support of a large area (300b); when the pressing is continued, the injection guide sleeve 300 is pressed by the skin and moves in a direction opposite to the injection direction A, and the latch 310 is also moved to compress the elastic member 320. The greater the elasticity is generated, the elastic force acts on the injection guide sleeve 300 so that the proximal plane 300b is in close contact with the skin to support the hand to avoid its shaking; when the injection guide sleeve 300 is retracted, the tip of the injection needle 30a protrudes from the injection guide. When the sleeve 300 is at the proximal end plane 300b, the injection needle 30a begins to penetrate the skin. As shown in FIG. 9, when the injection needle set 30 is to be mounted, the needle 310 is pushed by the finger to drive the injection guide sleeve 300 back along the groove 100c of the base 100, until finally, the end track of the groove 100c is axially Instead of radial, the latch 310 will eventually be parked at the end point 100f in order to maintain the injection guide sleeve 300 at this height position, at which point the needle mounting portion 10a at the proximal end of the syringe will be completely exposed, facilitating the patient to install the injection needle. After the assembly 30 is completed, the latch 310 is again dialed to return to the starting point 100d. As shown in FIG. 10, the proximal end of the injection guide sleeve 300 has a guiding space 300c which is in mating contact with a feature size 30c on the injection needle sleeve 30b. When the injection is completed, the needle sleeve 30b is guided back. The sleeve is used to disassemble the needle 30a. During the process, the injection needle 30a is completely enclosed within the injection guide sleeve 300 and the needle cover 30b to prevent the user from being injured by the injection needle 30a. In addition, the injection guide sleeve 300 has a perspective and magnification function, in order to visualize and enlarge the injection site to avoid bleeding from the blood vessel.
如圖4、6所示,該基座100的近端有一凸緣100b,內部空間裝置有一光源模組400,該光源模組400由1個照明光電板410及複數個照明元件420所組成,該光源模組400經由電力傳輸導線610連接至電力單元電路板620,再經由導電體A 630、供電元件640、導電體B 650、電力單元蓋660、電力單元盒670及電力單元電路板620所構成的導電通路而取得電力,供應照明元件420發光。當電力單元蓋660的螺紋部660a與基座100側面電力單元盒670之螺紋部670a鎖緊時,則通路上所有元件受壓彼此互相連接,迫使該電路導通,鬆開時則形成斷路,無法供電;其中,電力單元蓋660及電力單元盒670皆具有可導電性,絕緣環690用來隔絕供電元件640之正負極,避免短路,密封環680被用來隔絕水氣及避免電力單元蓋660因長期旋轉鬆動而無法與電力單元盒670有效連接。僅利用旋轉電力單元蓋660即可控制電路的導通與不導通,這是本新型較佳實施例的開關機制。相對於習用注射器沒有自體光源需借用其他照明設備,本創作更能幫助病患不受環境與時間的限制按時進行注射,不會延誤有效注射的時機。As shown in FIG. 4 and FIG. 6 , the base 100 has a flange 100b. The internal space device has a light source module 400. The light source module 400 is composed of an illumination photoelectric plate 410 and a plurality of illumination elements 420. The light source module 400 is connected to the power unit circuit board 620 via the power transmission line 610, and then via the conductor A 630, the power supply element 640, the conductor B 650, the power unit cover 660, the power unit box 670, and the power unit circuit board 620. The conductive path is formed to obtain electric power, and the illumination element 420 is supplied to emit light. When the threaded portion 660a of the power unit cover 660 is locked with the threaded portion 670a of the side power unit box 670 of the base 100, all the components on the passage are pressed and connected to each other, forcing the circuit to be turned on, and when the loosening is formed, an open circuit is formed. Power supply; wherein the power unit cover 660 and the power unit box 670 are both electrically conductive, the insulating ring 690 is used to isolate the positive and negative poles of the power supply component 640, to avoid short circuit, and the sealing ring 680 is used to isolate moisture and avoid the power unit cover 660. The power unit box 670 cannot be effectively connected due to long-term rotation loosening. The conduction and non-conduction of the circuit can be controlled by only using the rotating power unit cover 660, which is the switching mechanism of the preferred embodiment of the present invention. Compared with conventional syringes, there is no need for other lighting equipment to use self-light source. This creation can help patients to inject on time without environmental and time constraints, without delaying the timing of effective injection.
如圖5、6所示,深度調整件500內緣一環狀區域500a與基座100外圍溝槽100g結合且可沿基座100的徑向做若干角度的旋轉。深度調整件500有一軸向開槽500b,以軸向開槽500b為中心,左右各有一組不同高低的圓弧缺口500c,500d,該二組缺口尺寸、形狀完全相同且左右對稱。(圖9)當使用者要安裝或更換注射器之針頭時,軸向開槽500b必須旋轉至與基座100之溝槽100c同心,以便注射導套300上之插銷310可沿著基座100之溝槽100c向上移動到終止點100f處,而中途不被深度調整件500擋下,在該位置時,注射導套300完全縮入基座100的近端而針頭安裝部10a會裸露出來;(圖8)當使用者要施行注射時,可旋轉深度調整件500,使圓弧缺口500c或500d移至基座100之溝槽100c之中心線上,便可擋下插銷310於圓弧缺口中,進而阻止注射導套300繼續向上移動,此時,針頭伸出注射導套300的長度即是針頭插入皮膚的注射深度D。藉由旋轉深度調整件500以選擇不同高低圓弧缺口500c或500d即可預先設定有效注射深度,注射時只需下壓注射器,到達設定深度時注射導套300自然會停止,完全不需擔心注射深度不夠或注射太深。有時注射的深淺確實會影響注射的效果,以胰島素注射為例,注射深度不夠,胰島素會進入皮膚,因而影響胰島素的起效時間和作用時間;注射深度太深,胰島素會進入肌肉而於此處更快速吸收,但是作用時間無法持續太久,此外,注射肌肉會使疼痛感加重。As shown in FIGS. 5 and 6, an annular region 500a of the inner edge of the depth adjusting member 500 is coupled to the peripheral groove 100g of the base 100 and is rotatable at several angles in the radial direction of the base 100. The depth adjusting member 500 has an axial slot 500b centered on the axial slot 500b, and each of the left and right sides has a set of different height arc notches 500c, 500d. The two sets of gaps have the same size and shape and are bilaterally symmetrical. (Fig. 9) When the user wants to install or replace the needle of the syringe, the axial slot 500b must be rotated concentric with the groove 100c of the base 100 so that the latch 310 on the injection guide sleeve 300 can be along the base 100. The groove 100c is moved upward to the end point 100f, and is not blocked by the depth adjusting member 500 in the middle, in which the injection guide sleeve 300 is completely retracted into the proximal end of the base 100 and the needle mounting portion 10a is exposed; 8) When the user wants to perform the injection, the depth adjusting member 500 can be rotated to move the arc notch 500c or 500d to the center line of the groove 100c of the base 100, so that the pin 310 can be blocked in the arc gap. Further, the injection guide sleeve 300 is prevented from continuing to move upward. At this time, the length of the needle extending beyond the injection guide sleeve 300 is the injection depth D at which the needle is inserted into the skin. The effective injection depth can be preset by rotating the depth adjusting member 500 to select different high and low arc notches 500c or 500d. Only the syringe is pressed down during the injection, and the injection guide sleeve 300 naturally stops when the set depth is reached, and there is no need to worry about the injection. Not deep enough or too deep for injection. Sometimes the depth of the injection does affect the effect of the injection. In the case of insulin injection, the injection depth is not enough, insulin will enter the skin, thus affecting the onset time and duration of action of the insulin; the injection depth is too deep, and insulin will enter the muscles. It absorbs more quickly, but the duration of action does not last long. In addition, the injection of muscles can increase the pain.
當注射完畢移除針頭時,為了保持筆型注射器10針頭安裝部10a不被環境污染,塞頭20可塞入注射導套300的近端導引空間300c,避免灰塵、異物等侵入。要開始注射時,拔除塞頭20並將它塞入電力單元蓋660之尾端,以免遺失(圖7)。When the needle is removed after the injection is completed, in order to keep the needle-type syringe 10 of the pen-type syringe 10 from being contaminated by the environment, the plug 20 can be inserted into the proximal guide space 300c of the injection guide sleeve 300 to prevent intrusion of dust, foreign matter, and the like. To begin the injection, the plug 20 is removed and inserted into the end of the power unit cover 660 to avoid loss (Figure 7).
本創作較佳實施例的使用方式如圖7所示,將筆型注射器10由注射輔助裝置套筒210的頂端開口210b插入並停留在適當位置(注射針頭30a存在時,使其尖端藏於注射導套300之內),旋緊基座100與套筒210的螺紋部,將該注射輔助裝置固定在筆型注射器10上。(圖9)施行注射前,以手指撥動注射導套300上的插銷310,使其向上移動到終止點100f處,此時注射導套300會完全縮入基座100之中,筆型注射器10前端的針頭安裝部10a會完全裸露出來,即可旋轉安裝注射針頭組30(含注射針頭30a,針頭套30b);接著用手指撥動插銷310使其移回起始點100d,注射導套300便彈回,順便將注射針頭套30b頂出使其脫離注射針頭30a,並突出於注射針頭30a尖端而將注射針頭30a藏於內,此時即可準備開始注射。(圖8)注射開始前,先以酒精棉片對注射區域進行消毒,然後旋轉深度調整件500使圓弧缺口500c或500d轉到插銷310移動的路徑上,拉起並旋轉筆型注射器轉輪10b以設定注射劑量;接下來準備開始注射;先將注射導套300近端平面300b貼緊注射區域,然後下壓筆型注射器10,接著注射導套300與插銷310會後縮,此時針頭伸出並刺入皮下,當插銷310頂到深度調整件500上的圓弧缺口500c或500d而停止(500c位置表示注射深度較淺,500d則較深)時,即可按壓筆型注射器10的轉輪10b給藥,完畢後,將筆型注射器10沿相反方向退出注射區域,到此,整個注射過程結束。需要照明時,旋緊電力單元蓋660;放鬆電力單元蓋660則關電。若要更換筆型注射器10的藥管10d時,鬆開基座100與套筒210之螺紋部100h/210c,筆型注射器10即可抽出。更換完畢後再按照以上步驟重複安裝並使用該輔助裝置。The preferred embodiment of the present invention is used as shown in Fig. 7. The pen type syringe 10 is inserted from the top end opening 210b of the injection aid device sleeve 210 and stays in place (the injection tip 30a is present in the presence of the injection needle 30a). Inside the guide sleeve 300, the pedestal 100 and the threaded portion of the sleeve 210 are screwed, and the injection aid is fixed to the pen injector 10. (Fig. 9) Before the injection is performed, the latch 310 on the injection guide sleeve 300 is moved by a finger to move up to the end point 100f, at which time the injection guide sleeve 300 is completely retracted into the base 100, the pen type syringe The needle mounting portion 10a of the front end 10 is completely exposed, and the injection needle set 30 (including the injection needle 30a and the needle cover 30b) can be rotatably mounted; then the latch 310 is moved by the finger to move it back to the starting point 100d, and the guide sleeve is injected. 300 is bounced back, and the injection needle cover 30b is ejected to disengage it from the injection needle 30a, and protrudes from the tip end of the injection needle 30a to hide the injection needle 30a, at which point the injection is ready. (Fig. 8) Before the start of the injection, the injection area is first sterilized with an alcohol cotton sheet, and then the depth adjustment member 500 is rotated to turn the arc notch 500c or 500d to the path in which the pin 310 moves, and the pen type syringe wheel is pulled up and rotated. 10b to set the injection dose; next, it is ready to start the injection; firstly, the proximal end plane 300b of the injection guide sleeve 300 is pressed against the injection area, and then the pen type syringe 10 is pressed down, and then the injection guide sleeve 300 and the insertion pin 310 are retracted, at this time, the needle is pressed. Extending and piercing the skin, when the pin 310 is stopped against the arc notch 500c or 500d on the depth adjusting member 500 (the position of 500c indicates that the injection depth is shallow, and the depth of 500d is deep), the pen injector 10 can be pressed. After the administration of the runner 10b, the pen injector 10 is withdrawn from the injection area in the opposite direction, and the entire injection process is completed. When lighting is required, the power unit cover 660 is tightened; the power unit cover 660 is turned off to turn off the power. When the cartridge 10d of the pen injector 10 is to be replaced, the screw portion 100h/210c of the base 100 and the sleeve 210 is released, and the pen injector 10 can be withdrawn. After the replacement, follow the above steps to repeat the installation and use the auxiliary device.
