▼200942286 六、發明說明: 【發明所屬之技術領域】 本發明係有關一種注射裝置,更特別的是,本發明是指一種使用 針頭並自動分配所輸注產品之手動注射的注射裝置,或者,是指一種 自動注射並自動分配的自動注射裝置。此注射裝置所輸注的產品是以 液體為較佳,而且可為藥劑,譬如胰島素、生長荷爾蒙或類似者。再 . 者’此注射裝置特別較適用於提供皮下注射、皮表注射或皮内的注射。 【先前技術】 先前技術中,一些常見的注射裝置,特別地包含了可裝設容器的 © 注射裝置,容器内具有欲輸注的產品,而且,注射裝置也可以在製造 的時候就裝設有容器,這種情形下,注射裝置提供給客戶的時候已經 包含了欲輸注的產品。另外一種注射裝置,是產品容器必須由注射裝 置的使用者自己來安裝。在使用之後,這種注射裝置可以被再次安裝 或使用,這種情形下,可以再次使用的注射裝置通常具有一驅動單 兀,使產品容器可以被裝上,亦使得它可以再次被卸下。可重複使用 注射裝置的優點在於,可以適用於相當昂貴的注射裝置,其藉由裝上 驅動單元,而可在輸注產品時更加方便。舉例來說,驅動單元可以再 度被使用,❿且裝上的產品容器在使用之後可以換上新的一個。 ^當安裝新的產品容器於驅動單元時,有時候會發生由於針頭已經 安裝於產品容器上’驅動單元的活塞桿作用在活塞上會受到產品的力 的影響,造成產如無法控制的方式作絲,或者,在產品容器上的 壓力會因為仙在活塞上的力輯加,當針頭被安裝上時,會造成產 品後來會被以無法控制的方式來分配。 這樣會非常的困擾,並且長期下來的花f也非常的昂貴,特別是 對於昂貴藥劑的情況。 【發明内容】 本發明的一個目的在於提出一種注射裝置,可降低不受控制的產 200942286 品分配之問題。 本發明之目的可藉由巾請專概圍第彳項所定義之特徵來加以達

器可以在近端為開口 ’而在末端呈現封閉,使得產品是容納在產品容 器的末端和位於近端之活塞之間。在末端,產品容器可以具有隔膜 (s_m),舉例來說,可關崎頭絲在產品容器的前端區域且 穿過隔膜’並藉此將產品容器内部的產品得赌注給病I舉例來說, 針頭可以。又計成用來提供皮下注射。可以藉由往末端處移動活塞來分 配十σ。舉例來說,假如產品容器在它的末端是以隔膜密封且產品 容器士並未提供針頭,則在受到—施力之活塞上的壓力會大於活塞與 產品容器之内壁所產生的摩擦力,這將導致活塞發生些微的位移雖 然這樣的位移以肉眼來看可能看不到’不過,這會導致產品上的麼力 增加。 置1具有—赋裝置,利用固找置可以將產品容器安 裝到與動早疋。產品容器本身可能會構成固定裝置或者,可以是至 t部分的固定裝置或包含至少一部分的固定裝置。較佳者是提供產 4器之蚊座’在這種例子中,產品容器之峡座會構成至少一邻 分的固定裝置’可以將產品容妓裝到驅動單I產品容器之固定座 也可以指的是一種產品容器支撐座。一般來說,這樣的一個零件可以 譬如為凸輪或相元件。舉例來說,產品容料難可以為套筒狀, ϋίΓ部能容納產品容[產品容器支撐座可以在近端為開口, 备替換產品容器時,使得產品容器能夠透過它的開σ被替換。 .200942286 ❹ 說產m»谷器支撐座的末端可以具有_,抵住產品容器的施麼而 ,夠固定密封或鎖固。舉例來說,當產品容器安裝到驅動單元時,產 ⑽谷器可以侧科峰進達咖定密封的狀態其巾彈簧可以包含 Ϊ驅動單切。舉例纽,雜__供-種容㈣方法,可以抵 Hi容器賴向公差,原則上,對使用者來說,也可能利用其他手 達到推動產品容器形成固定密封的狀態。產品容器或產品容器支 可以具有-種裝置,可以將針翻定在產品容器的末端區域上。 為了分配產品’注射裝置,特別是指驅動單元,可以包含用來移 $活塞所需要的裝置崎配產品所需要的能量可以藉由手動提供,或 量產、生裝置或儲存能量的裝置。舉例來說,手動提供的能 ,了 ^換為々配位移》手動提供的能量也可以儲存在能量儲存裝 ,月b量儲存裝置譬如為彈簧。根據使用者 ,成活塞的驅動位移與分配位移。能量產生裳置的例;子= 達、藥劑推進器(_^__昨_伽「诉)或類似者。 為了分配產品’注射裝置’特別是指驅動單元,可以具有輪 此輸出耕要_麵塞±,並往分_方向,_是往末端 套筒ΐ推的產品。輸出元件可以為中空體,換言之呈 ❹ 傳送力量’可以在輸出稱或活塞的末端提供 = 鄰接著活塞或者靠在活塞上。 凸緣了以 產品容器可以從未鎖固位置移動到鎖固位置。為此,產。。 以產生相對於驅動單元之旋轉運動㈣ =。舉例來說,在未鎖固位置,產品容器可以位

移動到底為止,當活塞達到鎖固,輸出元件會移動到和活塞相接觸。 輸出元件最好利用彈簧元件來往末端方向推進至少一段距離,而在鎖 固操作期間達到鄰接接觸。彈簧的力相當地低,特別的是,彈簧力較 移動活塞所需要的力要弱。在鎖固過程中,和活塞建立接觸的特別優 點在於,當輸出元件一開始往分配方向移動時,因為不需要先克服輸 出元件和活塞之間的距離,期望的劑量就已經分配好了。在將空氣從 產品容器或/和針頭_出_,舉例來說,最好可以在啟動時讓輸出 7C件先移動-段距離以分配劑量,或者,可以選擇使用馬上分配一套 產品劑量。 為了避免產品在產品容器移動到鎖固的期間中發生無法預期的分 配,當輸it}元件已經和活塞建立接觸時,輸出元件不會和產品產生相 互作用直到產品容器已經達到鎖gj位置,此鎖gj位置制是指包含產 品容器已經確實達到鎖固的位置。在此之相互作用(interact)是指沒

合凸輪16c與50c的寬度近似。 、 如第4圖所示,導引套筒26是容設於套筒50内,套筒5〇也可 以稱為是卡口式套筒。導引套筒26是被連接至殼體12,因此是無法 轉動的,但是可以軸向移動,並且導引套筒26是連接至卡口式套筒 50,因此可以轉動,但是無法軸向移動。因此,當卡口式套筒5〇由非 鎖固位置移到鎖固位置時,導引套筒26相對於殼體12徑向導引移動, 反之亦然。 如由第1圖所示,一螺紋插入物6連接至導引套筒26,,因此它 是無法轉動或者軸向運動,特別是閂住的。螺紋插入物6與導引套筒 11 200942286 26也可稱為設置元件6、26。螺紋插入物6具有一内螺紋6a,而輸出 元件2的外螺紋2a是導引在内螺紋6a内,在這個範例中輸出元件2 也可以稱作活塞桿,因此當輸出元件2轉動時,它是藉由螺紋插入物

Description of the Invention: [Technical Field] The present invention relates to an injection device, and more particularly, to an injection device that uses a needle and automatically dispenses a manually injected injection product, or Refers to an automatic injection device that automatically injects and automatically dispenses. The product to be infused by the injection device is preferably a liquid and can be a medicament such as insulin, growth hormone or the like. Further, the injection device is particularly suitable for providing subcutaneous injection, skin injection or intradermal injection. [Prior Art] In the prior art, some common injection devices, particularly including an injection device in which a container can be mounted, have a product to be infused in the container, and the injection device can also be provided with a container at the time of manufacture. In this case, the injection device is already supplied to the customer and already contains the product to be infused. Another type of injection device is that the product container must be installed by the user of the injection device. Such an injection device can be reinstalled or used after use, in which case the reusable injection device typically has a drive unit that allows the product container to be loaded and allows it to be removed again. The reusable injection device has the advantage that it can be applied to a relatively expensive injection device which can be more convenient for infusion of the product by mounting the drive unit. For example, the drive unit can be used again, and the loaded product container can be replaced with a new one after use. ^When installing a new product container on the drive unit, sometimes it happens because the needle has been mounted on the product container. The piston rod of the drive unit acts on the piston and is affected by the force of the product, causing the production to be uncontrollable. The wire, or the pressure on the product container, can be added by the force on the piston. When the needle is installed, the product will later be dispensed in an uncontrollable manner. This can be very troublesome, and the long-term flower f is also very expensive, especially for expensive pharmaceuticals. SUMMARY OF THE INVENTION One object of the present invention is to provide an injection device that can reduce the problem of uncontrolled distribution of product 200942286. The object of the present invention can be achieved by the features defined in the section, and the advantageous embodiments are defined by the subsidiary. For example, the hairpin provided by the present rider includes a drive unit and a product container attached to the movable unit. Preferably, the product container is used up and lost, and the drive unit is The best is a repeatable user. For example, the product container can be an ampoule or a capped ampoule containing a piston that can be moved relative to the product container. For example, the piston can be a thief. Seal (four) (丨丨 (10) pays fine). The product container can be open at the proximal end and closed at the end such that the product is received between the end of the product container and the piston at the proximal end. At the end, the product container may have a septum (s_m), for example, a Kawasaki silk thread in the front end region of the product container and passing through the membrane 'and thereby betting the product inside the product container to the disease I, for example, The needle can be. Also counted to provide subcutaneous injection. Ten sigma can be assigned by moving the piston towards the end. For example, if the product container is sealed at its end with a septum and the product container does not provide a needle, the pressure on the piston subjected to the force application will be greater than the friction generated by the piston and the inner wall of the product container. This will cause a slight displacement of the piston. Although such displacement may not be visible to the naked eye, 'however, this will increase the force on the product. With the built-in device, the product container can be installed in the early morning. The product container itself may constitute a fixture or may be a fixture to the t-part or a fixture comprising at least a portion. Preferably, the mosquito net of the device is provided. 'In this example, the fungus of the product container will constitute at least one adjacent device. The product can be accommodated in the holder of the single product container. Refers to a product container support. Generally, such a part can be, for example, a cam or a phase element. For example, the product can be difficult to be sleeve-shaped, and the product can accommodate the product [product container support can be open at the proximal end, when the product container is replaced, so that the product container can be replaced by its opening σ. .200942286 ❹ The end of the m»bar support can have _, against the application of the product container, enough to seal or lock. For example, when the product container is mounted to the drive unit, the product (10) can be placed in a sealed state, and the towel spring can include a single drive. For example, the New Zealand, Miscellaneous__Supply-Growth (4) method can resist the tolerance of the Hi container. In principle, it is also possible for the user to use other hands to push the product container to form a fixed seal. The product container or product container holder can have a device that can be placed over the end region of the product container. In order to dispense the product 'injection device, particularly the drive unit, the energy required to transfer the device to the desired product of the piston can be provided manually, or mass-produced, raw, or stored. For example, the manually provided energy, the energy supplied by the switch to the displacement can also be stored in the energy storage device, such as a spring. According to the user, the displacement and displacement of the piston are shifted. An example of energy production; sub = 达, drug propeller (_^__ yesterday _ gamma "suit" or similar. In order to distribute the product 'injection device' especially refers to the drive unit, you can have this output _ The surface plug ±, and to the direction _ direction, _ is the product pushed to the end sleeve. The output element can be a hollow body, in other words, the transmission force can be provided at the output or the end of the piston = abutting the piston or leaning on The piston is flanged so that the product container can be moved from the unlatched position to the locked position. For this purpose, to produce a rotational movement relative to the drive unit (4) =. For example, in the unlatched position, the product The container can be moved to the locking position by means of her displacement device. The necessary user is interested in the production of the yarn n or the product container shredded 3 to: the rotary connector is - preferably, if Before the product container reaches the locking position, the output member is in abutting contact with the live 200942286 plug or moved into abutting contact with the piston. In other words, during the movement of the product container from the unlocked position to the locked position, the output member Move to the piston until the product container reaches the locked position. For example, the piston can be moved to the end by gravity, and when the piston reaches the lock, the output member will move into contact with the piston. The spring element is preferably used to advance at least a distance toward the end, and the abutment contact is reached during the locking operation. The force of the spring is rather low, in particular, the spring force is weaker than the force required to move the piston. During the locking process A particular advantage of establishing contact with the piston is that when the output member initially moves in the direction of the dispensing, the desired dose is already dispensed because there is no need to overcome the distance between the output member and the piston. The air is removed from the product container. Or / and the needle _ out _, for example, it is best to let the output 7C piece move first - the distance to dispense the dose at the start, or you can choose to use a set of product dose immediately. To avoid the product moving in the product container Unexpected distribution during the locking period, when the input component has been in contact with the piston, The component does not interact with the product until the product container has reached the position of the lock gj. This lock gj position system refers to the position where the product container has indeed reached the lock. The interaction here means no, force On the piston, it is possible that the wire plug moves - a considerable amount of transfer to dispense the 'time' or 'may at least cause an increase in the pressure on the product container blue product. This means 'if the needle is placed before the product container, the needle will be No, the product will be assigned in the locking operation, and under this _, after the _ product container, the needle will be fixed, no product will be due to over pressure on the product (brittle (Q) (four)) - also available In the case of a setting member, for example, it can be connected and fixed to the output unit, the fixing method can be screwed. According to this, the destination unit can have an external thread and the setting unit can have an internal thread. Preferably, at least one of the output units cannot move relative to the setting unit, and at the same time, avoiding the elimination of the flow of the object can be maintained in the locking movement of the entire product container, preferably, it is difficult to partially transfer the money. Product container. The difficulty of the stopover occurred in 200942286 until the arrival of the lock position, in other words, before reaching the end of the lock movement. For example, the binding state can be actuated by the locking movement of the product container or/and the product container: causing the shaft to be disengaged, and the wheeling unit to stop the flow in the setting unit. For example, the output unit can be used in the part of the lock @product container movement # relative to bribe, preferably, also brain. When the output unit is unable to move in the axial direction, the partial __ movement preferably occurs before the lock moves to the position of the lock, in other words, at the beginning of the lock movement, = The order 7C is likely to be axially decorated relative to the main unit and can be moved to the locking position ❹. Therefore, in fine movement, the movement of the output unit relative to the setting unit =, the 'better' of the lock, when the product capacity 11 is moved to the position of the lock 13 at the unlocked position, less ί can be moved axially, for example The product container can be in close proximity to the j soap 4_ to the moving sculpture or the miscellaneous, the setting unit is rotatable, but the comparison is to avoid rotation relative to the driving unit, since the setting unit is relative to the driving unit == body _ To the sewing force, the interaction of any of the feed elements of the domain is ''even though the output unit is in the axial direction cannot move relative to the set unit. M 佳 'At least the piston, setting unit, and output unit can work together to move the product container from the unlatched position to the sturdy drive, the output unit, or the set unit can When the product j is attached to the tilting unit, the axial direction is prohibited from moving. In order to distribute the product, the person can move axially or rotationally. In the preferred embodiment, the output unit positions the setting unit by means of a threaded joint, and the output unit can be locked and rotated in the direction of the distribution. Distribute the product, once the product capacity = 3 = the way of the process, to be removed by the drive unit, in order to re-change, the output unit of the unit, the output unit can be used with the knife, ^ β, especially the direction of the near side , to lock back to the drive unit, 'can be used by the user to use the finger to reverse the product allocation of the square unit to wire, or to produce 4 device relocation _, can also provide a kind of joints (release _ to release the rotational movement of the 200942286 output unit relative to the setting unit; here it is particularly pointed out that this preferred embodiment can also release the rotational movement of the output unit relative to the setting unit to dispense the product. When the container is moved from the unlocked position to the locked position, preferably the coupling member can be moved to the engaged state to lock the movement of the output unit relative to the setting unit. When the rotational movement is stabilized, the output unit will not be able to be threaded with respect to the setting unit in the dispensing direction or opposite to the dispensing direction, and the product container can also be used as a connecting component, such as a locking sleeve, Moved from its proximal end to establish a fixed relationship; for example, 'the present invention can provide a spring' acting between the coupling element and the product container, one direction is skewed to the coupling element, the other direction, in other words In other words, the reverse direction is connected to the trout, and more than one intermediate medium element can also be provided between the spring and the product container. In a preferred embodiment, the energy of the dispensed product can be provided by a spring device, in particular A torsion spring, the torsion spring is in a spiral shape, in particular by a strip material, which can be wound around the long axis of the injection device. The energy of the product can be transmitted by a transport device. To the output member, for example, the transfer device can be a similarly-like bond that can be engaged or not engaged when the note (four) is placed, thus In order to allow the product to be dispensed. For example, 'the guide sleeve can also be provided as part of the transport device, but can be moved axially relative to the output member and cannot be rotated relative to one another, for example, the transport element At least one long axial groove is provided for the component arrangement. For example, the component of the sleeve can be wound around the sleeve in a sleeve-like configuration and can be rotated relative to the component. Moving in the axial direction, in particular, is connected to the setting element. Therefore, when the reading axial movement is set, the tree will also follow the axial movement. For example, the component can also be assigned to the generalizing device (4). As a part of the joint member, the rotational movement of the output member is avoided, for example, combined with the element-like component. The energy of the product can be added by a transmission device, or may be included. The above components are read in 200942286. In a preferred embodiment, the securing means can be based on the operation of pushing a fixed rotational connection, in particular a bayonet fitting, a drive unit, in particular The body has a guiding track for a cam to rotate in the upper direction and moves from the releasing position to the fixed position. The releasing position preferably corresponds to the unlocked position of the product container, and the fixed position corresponds to the product container for driving. The locking position on the unit. Due to the design of the guide rail, the product container preferably produces axial movement during the rotational movement, and the cam of the fixation device disposed on the guide rail may be formed by at least a portion of the product container, preferably by a product container The support is formed. The fixing device has at least a portion to enable the cam to be disposed on the guiding rail in a moving direction, and once the cam, in particular a part of the cam, is placed in the guiding slip by the axial movement, the cam It is then possible to rotate from the release position to a fixed position, for example, thereby causing axial movement of the product container, while pushing the setting element and/or the axial coupling. More preferably, the setting member can be axially moved by the red wheel and/or be coupled to the cam for coordinated axial movement. In the preferred embodiment, the cam can be formed of at least two components positioned adjacent to each other. A fixed torsion is set and can be moved to a fixed position and clamped to each other axially by guiding the slide rails. For example, the two components constituting the cams may have cam-like protrusions respectively, which can be axially adjacent to the matching guides in cooperation with the guide rails; for example, the two components may be sleeve-shaped respectively relative to the drive list 7C housing rotation and axial transfer. For example, the torsion force applied to one of the jaw members can be transmitted to the other member by the @ fixed torque transmission coupling, so that the cam formed by the axial batch can be moved to the fixed position by the rotational motion, The two parts having the shape of the end face of the mouth can achieve the transmission of the fixed torque. Preferably, the material is the product H, or the product capacity seat, and/or other bayonet sleeves (bayonetS|eeve&gt In order to change the product container, the product container is inserted into the product container support, and the product container support unit transmits the moving human drive unit with a fixed torque by pressing the fixed movement, and the product capacity is due to the axial direction. The movement and the other components forming the protrusions are configured to fix the torque transmission. The user of the injection device uses the movable product container support seat, so that other components connected to the product container support base will also rotate. Due to the rotational relationship, the two cam elements will also move along the guide track 200942286 to a fixed position, and the axial width of the guide track is roughly equivalent to the two adjacent The wheel elements are such that they are axially clamped to each other. Therefore, the product container connected to the drive unit will also move axially together 'because another component constituting the cam will also rotate and be placed on the medium device'. When the container is disposed on the swaying unit, various movements can be transmitted to the mechanism of the driving unit, and the two components constituting the cam of the fixing device are rotatable and axially movable relative to the driving unit, and preferably, can be connected to the setting unit. It is rotatable but axially fixed. For example, the housing of the drive unit can have a guide rail for the setting unit to be fixed so that it can only move axially and cannot rotate. The fixing described here. The device may also be constituted by other individual patent applications, in which the applicant reserves the right to apply the fixing device in other divisional manners. To further enhance the object, technical content, features and effects achieved by the present invention. The following is a detailed description of the preferred embodiment and is described below with reference to the various figures. Referring to the symbols of the drawings. [Embodiment] The syringe shown in Fig. 1 includes a reusable drive unit; and a product container 27 connected to the drive unit, which can be accommodated in a reusable sleeve shape The product container support 16' product container 27 can be secured to the drive unit with the aid of the product container support 16. The product container 27 - but empty can be removed by the syringe and replaced with a new one. In the mounting step, the housing 12 is of a multi-part design having elements 12a, 12b that are connected or inserted into the housing 12. In principle, the housing 12 can also be a single part. The product container 16 is utilized. The means for mounting the plug is attached to the drive unit, and the drive unit is constituted by the housing 12, the product container support 16 and a sleeve 50. The product container support 16 is a cover 31 which is disposed on the housing 12. Covered and removed when the syringe is ready for use and installed back later. Figures 2 through 5 depict the necessary components of the fixture provided by the mounting plug type. The product container support 16 has a cam 16c that extends radially outwardly and the proximal end surface is designed to be attached to the end surface of the sleeve 5G, such as a fixed torque transmission mounting, such as a positive end 200942286. As shown in Fig. 5, the housing part force part 12 is omitted for the purpose of explanation. The sleeve 5Q has at least one radially outwardly extending cam == turn, 50c is part of the mounting for fixing. The cam coffee is disposed in the casing 12, particularly in the case where the part of the shell portion is formed as a guide rail formed, and the rail 12e has at least one inclined surface 12g. When the sleeve 5 is rotated by the rotation, the sleeve 50 is moved in a rotationally movable manner relative to the housing portion. As described below, the 'sleeve 5G peak-to-line production line has a good & good effect. ❹ ❹ In order to mount the product container 27 to the drive unit, a new product container 27 is guided to the product container holder 16 via the nearest end. The product container cut-out 16 is then axially-independent to produce a torque-actuated mounting that is side-sounded to 50' so that the cam 16c is inserted through the opening 12f (Fig. 2) into the guide rail. First, the figure shows that the needle is not in the product. In the non-sense state, the cam 50c is axially disposed and axially adjacent to the opening i2f, and the product container support 16 can be fixed by pushing. Subsequently, the cam 攸 and the 5 〇c abut each other to form the common cams 16c and 5Qc (Fig. 5). Rotation of the product container holder 16 can drive the sleeve 50. Due to the inclined surface 12g, the sleeve 5〇 and the product container support 16 are also axially movable. At the end of the rotation, e.g., at the locked position, the common cams and 5 are disposed in the region 21h of the guide rail 12e, and the two cams 16c and 50c are clamped by the side edges of the guide rail 12e. At the end, the drawing width of the guide rail of the region 12h is similar to the width of the engaging cams 16c and 50c. As shown in Fig. 4, the guiding sleeve 26 is accommodated in the sleeve 50, and the sleeve 5〇 may also be referred to as a bayonet sleeve. The guiding sleeve 26 is connected to the housing 12 and thus is non-rotatable, but is axially movable, and the guiding sleeve 26 is connected to the bayonet sleeve 50 so that it can be rotated but cannot move axially . Thus, when the bayonet sleeve 5 is moved from the unlocked position to the locked position, the guide sleeve 26 is guided radially relative to the housing 12 and vice versa. As shown in Fig. 1, a threaded insert 6 is attached to the guide sleeve 26 so that it cannot be rotated or axially moved, particularly latched. The threaded insert 6 and the guiding sleeve 11 200942286 26 may also be referred to as setting elements 6, 26. The threaded insert 6 has an internal thread 6a, and the external thread 2a of the output member 2 is guided within the internal thread 6a, which in this example may also be referred to as a piston rod, so that when the output member 2 is rotated, it It is guided proximally or at the end by the internal thread 6a of the threaded insert 6, for example, when rotated, relative and directionwise guidance according to the direction of rotation. The outer surface of the output member 2 has a thread 2a which is interrupted by two grooves 2b extending circumferentially opposite each other in the axial direction. A component part of a conveying element 7, K2, 5, in combination with the sleeve 5, has two projections 5a, 5b which are directed radially inwardly at the ends and are lying relative to each other and projecting into the output Inside the groove 2b of the element 2. The coupling member 5 is coupled to the setting member 6' 26 so that it can be rotated, but cannot be moved. The rim element 2 is locked to prevent rotation relative to the engagement sleeve 5, but is axially movable relative to the coupling sleeve 5 when the output member 2 is rotated relative to the mounting member 2, 26. The coupling sleeve 5 is not axially movable unless the product container 27 is removed. The drive shaft 7, which is provided at the proximal end of the syringe and which constitutes a part of the transport elements 7, K2, 5, has a toothed structure 7a which extends inwardly and which constitutes the joint element of the joint Κ2. In operation, for example, when the operating member 15 is pushed in the distal direction, the drive shaft 7 and the toothed structure 7a are moved in the distal direction, with the result that the toothed structure 73 is seated at the proximal end of the coupling sleeve 5 and establishes a fixation. The torque drive, especially the positive connection. a spring element or drive spring 3, which may be in the form of a coil spring or a clock spring, and connected to the housing 12 via a spring end of the spring element 8 on the outer surface of the spring element 3, the spring sleeve 8 is for preventing rotation 'with respect to the housing 12' but is capable of axial movement. At the other end, the drive spring 3 is connected to the drive shaft 7. The energy stored in the spring element 3 can be output, for example, the drive shaft 7 is rotated relative to the housing. In order to dispense the product, the energy of the spring element 3 is transmitted through the transport elements $, 7 in a rotationally movable form to the output element, so that the rear half is locked in the end direction, for example in the direction of the direction, for the setting elements 6, 26. And pushing the piston 28 to dispense the product from the product container 27. For implementation with a product dose, a user can rotate the dose setting member 9 provided in the form of a dose setting button 12 200942286 that is axially fixed relative to the housing 12. The dose setting member 9 is coupled to a coupling member 1 through the coupling member 3, so that rotation can be avoided. The knot member Κ3疋 is formed by the mesh, groove or tooth shape of the dose button 9 and the button 9 is connected with the mesh, groove or toothed positive assembly of the splicing disc 10 to establish a joint. A piece that can be disassembled by moving the bonding element 1 在 in the end direction. The bonding element 1〇 can be decomposed by the operating element 15 to move. In the case of not being operated, the engaging member 3 is held in a joined state with the engaging member 2 which is brought into an unbonded state by the spring member 19, and urges the drive shaft 7 in the proximal direction. The engaging member 3 is engaged during the setting operation of the dose, for example, the rotational movement of the dose setting button 9 is transmitted to the bonding member. The coupling element 10 is connected to the drive shaft 7 so that it cannot move and rotate axially, and it can also be the entire ship-part of the drive shaft 7. The rotational movement of the dose setting member is not transmitted to the coupling sleeve 5 because the coupling member 2 is unbonded. When the drive shaft rotates, the drive spring 3 connected to the drive shaft 7 is tensioned. In order to prevent the dose setting button 9 from being rotated back during the setting operation because the drive spring 3 is tightened, a ratchet spring 11 or a ratchet mechanism including a ratchet wheel spring 11a, for example, as a clamp maintaining member, can be provided. The housing 12 of the syringe is provided, for example, as a component of the housing 12 such as the mechanical support 12a and the mechanical support 12b, and the *Hose setting button 9. The ratchet mechanism can be designed so that the drive spring 3's turns, _ is tensioned, can only be in the single _ direction. The ratchet system is designed to be personally pleasing, so it can also be a two-way rotary motion, especially the tension and release drive springs. 3 ^ Since the two-way rotation is possible, the product dose can be increased and decreased when the product dose is set. The currently set product dose can be read by a window 彳 2 (1) showing the piston barrel 4. The rotational movement of the drive shaft 7 can also be transmitted to the threaded sleeve 13 connected to the drive shaft 7, so that the cymbal cannot move axially or Is a rotation, and may be a part of it as a whole. The outer diameter 彳3a of the threaded sleeve 13 has at least one groove, and is provided with at least one mesh 4a showing the piston cylinder 4, so the rotational movement of the threaded sleeve 彳3 It is transmitted to the display cylinder 4 by the reverse rotation coupling mode, allowing an axial relative movement between the display cylinder 4 and the threaded sleeve 13. The display cylinder 4 has a thread 4b on the outer surface, which is set at 13 200942286 The internal thread 12c of the body portion 12b is thus shown to move due to the rotational movement of the piston barrel 4 relative to the housing 12 in the axial direction, and more in the end direction. The process of setting the dose by the dose setting button 9 shows that the piston barrel 4 is moving toward the end of the syringe (toward the left side of Fig. 1). A mark can be provided on the outer surface of the display cylinder 4. For example, a printed agent or a ruler can be read through an opening or window i2d on the syringe housing 12b, and the marking of the piston cylinder 4 is moved relative to the window 12d. 4 has an actuation stop in the circumferential direction at the end which will move to an adjacent contact at the maximum dose. This adjacent contact corresponds to a mating common operation stop provided on the general portion 12a. This matching stop portion is formed by the end shape of the annular portion of the body portion 12b. The advantage of using a stop portion acting in the peripheral direction over the axial stop portion is that the force acting on the stop portion is weak. The display cylinder 4 also has another rotation stop at its proximal end, which acts in the peripheral direction and moves to an adjacent contact when the minimum dose is reached, which corresponds to the setting The mating cooperating stop on the housing portion 12b. This mating stop is formed by the end of the annular gap of the housing portion 12c. Once the dose has been set and the magazine 3 is driven by The dose setting button 3 is ready for rotation, the set operation is completed, and the dose is filled when the spring 3 is tightened. To correct the dose, the dose setting button 9 is simply rotated in the opposite direction to reduce The dose can be set too high. The ratchet spring 11 can be designed as shown in Figures 14 and 15 of the patent application PCT/CH2007/000243, the teachings of which are hereby incorporated by reference. During this dispensing step, it is activated by pressing the push button 15, and due to the thread engagement with the internal thread 12c of the syringe, the display cylinder 4 is rotated backward in the opposite direction and moved backward in the proximal direction (toward) On the right side of the map, when it occurs, it will reach the direction in which the stop portion of the display cylinder 4 acts on the periphery of the housing 12a' 12b, particularly in the housing portion 12b. In a non-braking dispense movement, the rotary shaft 2 moves in the end direction without any relative force 14 200942286, for example, when no product container has been set, this operation may result in too high tension and deformation at the end position. Or even damage to the display cylinder 4 or the common operating portion 12b. Thus, a braking mechanism 17, 18' that acts to drive the movement will be provided as will be described below. The first coupling member K1 includes a coupling member as the locking sleeve 14, and a coupling sleeve 5. The first coupling member K1 is coupled to the housing 12 by the coupling sleeve 5, so that it cannot be in a special operation mode. Rotate, or release it to allow the weapon 12 to turn. When the product container 27 is replaced, the first coupling member K1 is preferably in a non-bonded state, and the output member 2 can be re-locked or re-locked in the most proximal direction and when the product is dispensed, the output member 2 can be locked in the direction of the end. The first coupling member K1 is preferably joined when the product container 27 is attached to the drive unit 7, and the operating member 15 is operated without. The first coupling member K1 provides the remaining form on the outer surface of the bonding nut 5, and the bonding yoke 5 can avoid axial movement relative to the locking sleeve = the device cannot rotate, especially with respect to the housing 以及 2 and : In the case of the 'Spiral Mosquito Sleeve 13', by operating the cultivating I5, the end of the shackle sleeve ntn the sleeve 13 will push the bearing 29, so that the bearing 29 is in the end, And in the type of the distribution operation, in addition, the 'bearing 29' may be a type of ball bearing disposed in the first-joint member bearing type. Therefore, the bonding element 14 ^ operates the towel, and the hybrid is heterozygous. The three-joining member 'operation: ΐ:: 'the fitting K1, the second coupling member Κ2, and the still and/or the driving shaft 7, which are pushed and pushed by the pressing device mounted on the operating member 15, The second end is combined with the pressing button 15 and the driving shaft 7 at the coupling sleeve 5, and the driving shaft 7 is prevented from being opposite to the sleeve 200942286. On the other hand, the first coupling member K1 and the second coupling member K2 can also be joined in reverse order. When the second coupling member K1 is coupled and the first coupling member K1 is disengaged, the third coupling member K3 is also disengaged due to the movement of the coupling member 10 relative to the dose setting button 9, and the coupling member 1 connected to the medium shaft 7 is When the third coupling member 3 is disengaged, it rotates relative to the housing 12. And the perfusion of the tiring spring 3 miscellaneous force can be mixed to the drive shaft 7' so that the torque applied to the drive shaft 7 is transmitted to the coupling sleeve 5 through the second coupling member 2, so that it is turned over 7 - Rotating, and transmitting this whirl to the output member 2 but unable to rotate due to the coupling of the output member 2 to the coupling sleeve 5. In this embodiment, the output member 2 is designed as a screw. Therefore, by means of a threaded joint such as a fine meshing engagement with the setting member 6, 26, the movement of the output can be shifted in the end direction; The flange 1 at the end 2 can also be regarded as an output member such that the output member 2 is displaced in the distal direction of the injection device. In the product dispensing operation 1' because the direction in which the threaded sleeve 13 moves is opposite to the direction of the perfusion movement, the direction in which the cylinder 4 is moved is also opposite to the direction of the perfusion movement. In the normal state, in other words, when the predetermined product is finely distributed, the dispensing operation and in particular the displacement of the output member 2 will continue in the end direction until the piston cylinder 4 is in contact with the surrounding direction of the above-mentioned stopping operation; Preferably, the value read by the window has been rotated to zero. In the case of production and distribution, and the user releases the operating element, the first joint K1, the second joint K2, and the third joint K3 may be reversely combined or released during the operation. It is interrupted, and the value read by the window 12d indicates that the pre-set fully allocated shot is still aging. Therefore, the product allocation operation can be continued again by pressing the face for 1彳$15. By releasing the operating element 15, the dispensing can be stopped again, or the user can wait until all the products have been completely dispensed. When the product container is loaded below the maximum amount of medicament that can be indicated by the cylinder 5 16 200942286 ❹

Based on this object, the present invention provides a loop 30 that partially surrounds the coupling sleeve 5 and is located in the coupling sleeve 5 and is not rotatable relative to the sleeve 5, and is only axially movable. The live ring 30 is also externally The peripheral thread is coupled to the threaded sleeve 13 having an internal thread. With this arrangement, when the threaded sleeve 13 is rotated relative to the coupling sleeve 5, the movable ring 30 will be caused to move axially; and when it does not rotate relative to the ring 30, no axial movement will occur. . When the product medicament is set, the threaded sleeve 13 rotates relative to the joint sleeve 5, causing the loop 30 to migrate in the proximal direction. In other words, during the dispensing process, due to the fixation of the second joint member 2, the combination There is no relative movement between the sleeve 5 and the threaded sleeve 13 so that the live ring 30 does not move. After the product medicament is set and dispensed several times, the loop 30 is moved in close proximity to the drive shaft 7, so that even if the cylinders 4, 26 are actually allowed, it is no longer possible to increase the amount of medicament. The user can replace the original product container 27 with a new product container 27, for which purpose the user supports the product container by rotating the drive unit relative to the housing 12, 16 removed 'when the product container 27 纟When the locked position is moved to the unlocked position, in particular, the release is determined, and the disposing element 2, the disassembling member 2, and the coupling sleeve 5 move together with respect to the housing 12 and the coupling member 14 in the end direction, and are released. First bond =. The injection of the coupling sleeve 5 establishes the first coupling member Ki along the radial direction, and this will be placed at the end of the coupling 70 member 14 because the position of the output unit 2 is at the same time. Output 70 pieces 2 at this time will be able to fix the crane unit 7 by adding a slight force in the proximal direction, and when the loser 2 is recorded _, the combined money 5 can be relative to the application, and the sleeve 138 The reverse rotation of the product distribution causes the live loop to be again in the direction of the end. The snail __ method can also replace the elastic force of the reed element, which is 'at least across the whole distance __ part, and try to push the output element 2 back to the last 3 ^ t * element can be actuated or set in the output element 2 The advantages of the i ΓΓ member of the drive shaft 7 will be explained later in conjunction with the detailed description of Fig. 6. 'Which of the best' is that the spring element (four) force is less than the piston of the output element 2. 17 200942286 The force required. Further, during the process of 27, the component 25 wire is fixed to the product container holder 16 and is urged by the spring member 19 until it contacts the setting member 6, 26. This contact avoids the spring element 19 from being fully released when the product container 27 is removed. This has the advantage that, because when the product container 27 is removed, the ridge element 19 must provide a foot-elastic force to support the combination of the three-piece K3. status. According to the present invention, as the sixth riding, an elastic coupling flange can be used as an embodiment. After replacing the product container 27, the preferred one is an ampoule (amp〇u|e) or a capping ampule. (capped via丨) 'The user continues to inject as described in the operating instructions. This action is necessary. The aspect is that g is air in the product capacity II 27, and the other is because the output element 2 was previously fully pushed to The drive unit 7' and a different level of product container 27 are injected' to create a slight gap between the piston 28 and the flange 1. Fig. 6 is a view showing that the output member 2 has a flange 1 attached to the front end and the end, and is non-replaceably connected to the screw 2. As shown in Fig. 6, the spring member 38a is provided between the flange 1 and the threaded insert 6, and alternatively, the elastic arm 38a may be extended to an angled shape. This spring element 38a can be used to secure the flange 1 or/and the threaded insert 6, and the other way is to form an elastic jaw on the flange 1 and/or the threaded insert 6 by means of an injection mold (jnject-mou丨d). . Once the new product container 27 is inserted, a gap is created between the flange and the piston 28 使其 to create a slight tolerance due to the injection of particularly different grades of product containers 27 . After the push flange 1 is attached to the screw 2, the flange 1 abuts directly against the threaded insert 6 based on the embodiment of Fig. 1.

The same β A 18 200942286 It is known that the means for eliminating the gap between the flange 1 and the piston 28 is completely unnecessary and may even be omitted. Referring to Figure 1, the injection device 'particularly the drive unit comprises a first brake element 17 and a second brake element 18 for decelerating the rotating component, for example for the transmission element 7, K2, 5 or / Move with the drive unit. If the conventional injection device is not used correctly, in other words, if the product container is not inserted, but the injection device is still operating, there will be a considerable risk of excessive force causing damage to the injection device components. When the product container 27 is inserted, during the product dispensing operation, the force and movement of the product are damped due to the viscous force of the product, and in the absence of the product container, there is no such damping element.

In the second embodiment, the operation mode of each implementation aspect is the same. As shown in the first embodiment of Figs. 7A and 7B, there are two semi-brakes I? which are mutually latched, so that the two cannot rotate with each other, and preferably cannot move axially and have an irregular shape. The portions are formed toward each other with an annular space therebetween for the brake disc 18 to be accommodated. On the other hand, the ring _ can also have a predetermined width, and the half lions 17 and 18 can be relatively moved. The brake shoe 17 can be a complete design. The brake pad 17 of the 200942286 has a tooth portion 173 that can cooperate with and complement the tooth portion 13b, preferably having a corresponding or special tooth height ZH. In the complementary connection, the torque transmission between the transmission elements 7, c, 5 is not inserted, and the rotation of the brake disc 18 is deleted in the (10) device. When it occurs, the gate of the tile 17 is π1% to ensure the brake disc 18 In the threaded sleeve 13 and the brake Ϊ L, the _8a and the proximal tooth of the end of the brake disc 18 are moved to contact the mutually mating and complementary teeth i7b, i7a, respectively. Due to the private elastic deformation, and all the above-mentioned vibration amount, relatively hard loss; thus limiting the operating principle of the rotating member 13, 17 β, such as the 8th circle to read the same, the only difference is that the silk surface of the end surface thereof It is connected to the transmission element by the transmission county, or the thread*, so that it cannot be rotated. Since the semi-brakes 17 can be moved axially relative to the sleeves 13, the shaped teeth 17a, 13b can have a fixed pre-twist distance or a varying distance, due to the spring element 19, the profiled tooth, They can still be pushed towards each other and, therefore, can be moved into contact with the profiled teeth 18a, 18b. ^ Due to the vibration or oscillation between the brake disc 18 between the threaded sleeve 13 and the brake shoe 17, the angular velocity ω will be increased, and the increase of the braking force is not proportional to the increase of the angular velocity (1). Therefore, as shown in Fig. 9, The curve BS of the indicated braking force will be achievable. The braking force curve shown in Fig. 9 can be achieved by the braking mechanism provided by the present invention, and the braking force is increased by an angle of rotation speed or angular velocity ω. In theory, the braking force is low, or The zero state rises to the maximum angular velocity ω_ allowed, and the &^'>^#;^;^ gastric velocity increase is a sharp rise angle. As shown in Fig. 0, the rotation angle of the cylinder 4 is shown as a time parameter and the embodiment shown in the figure can cause three complete rotations (3 X 36 〇.). And it is known from the first figure that 'the piston cylinder 4 can be completely rotated three times after the time Wbraked, and this time tn〇n_braked is shorter than the rotation movement in the case where the piston cylinder 4 is decelerated, 200942286 The increase in the angle of rotation is ideally a linear distribution with the time parameter. Due to the braking force generated by the vibrating brake disc 18, the maximum possible angular velocity OJmax generated by the dispensing motion will be lowered or limited, so that the return rotation of the display cylinder 4 can be moved to the circumferential direction immediately adjacent to the stop actuation. Or, the housing member 12b can only reach the maximum speed defined by the brake members 13, 17, 18. It is assumed that the brake elements 13, 17, 18 are designed to show that the maximum possible contact speed of the cylinder 4 will be very low due to deformation or damage caused by the impact. Other types of brake mechanisms can also be applied to the brake disc 18 to vibrate between the threaded sleeve 13 and the brake shoe 17. For example, 'on the other hand, the third embodiment of the brake based on Fig. 12 is an example of a centrifugal brake, and the outwardly facing and replaceable brake shoe 41 is fixed to the transmission element 7, K2, 5 And/or the drive shaft 7, and/or other beta members that rotate relative to the drive shaft 7, such as the coupling element 1〇, the threaded sleeve 13, or the display cylinder 4, have a mass of one turn and can be like a rotating part Turn it around. The brake shoe 41 may, but not necessarily, be biased inwardly and outwardly toward the spring element, and the brake shoe may be radially rotated by centrifugal force or moved radially outwardly to move it to, for example, the housing 12. The sleeve 42 is combined with a fixed state. In the third embodiment, a thimble 4 or a fixing member which can be radiated outward is provided, and the end is provided with a brake pad 41 which is tilted by means such as a spring element. When the rotational speed in the case of non-braking, or only a part of the brake yoke elements 4, 7, 1 and 13 are sufficiently large, the brake pad 41 is subjected to centrifugal force and is radially displaced outward or borrowed. Supported by the support of the oblique spring, and movable to the outside, the sleeve 42', therefore, produces the desired braking effect due to friction, the outer stationary sleeve 42 can also be formed in the housing 12 or It is the case member 12b. Referring to FIGS. 11A and 11B, a fourth embodiment of the present invention is illustrated. The brake is a type of current brake 2〇, and the brake disc 21 is connectable to a rotating member that is to be decelerated, such as a transmission element. 7, K2, 5, and the drive shaft 7, the threaded sleeve 13, or the display: live, 4, and the element interacting with the brake disc 21 can also be connected to the housing 12, or tamping and placed in the shell The element of the body 12 or the element that rotates relative to the brake disc 21. The brake disc 21 is preferably made of a good electrical conductor, such as pure aluminum, copper, etc., the material of the rare earth 21 200942286 two magnetized magnets 22, the material is a material, the permanent magnetic field can be hit by 91 The stone 23 device is constructed to be connected to the air gap, which is extended by the brake disc #Α. The braking force is established by the surface and fluid density of the air gap, and the rated current value of the brake disc 21, for this purpose. The gas is reduced as much as possible, and the thickness of the brake disc is as large as possible. The brakes are greener than the average radius (working radius), and the brakes can be designed with a plurality of magnet systems to act on the brake disc 21. The calculation can be used to calculate the current density, braking power, and eddy current coffee, first class (4) meaning, and assume that the quasi-column magnetic pole half of the __ 21 Wei must be small enough to be a predetermined material The estimation is inaccurate, and becomes a nonlinear state by (4) the magnetic field of the nucleus also causes insufficient feedback. Preferably, the neodymium magnet 22 and the magnet unit 23 are attached to the housing 12 of the injection device, or the housing 12b, or other non-rotating component, to cause the desired thirst current on the cartridge 21. Cry from the fourth embodiment shown in Fig. 13 and Fig. 14, the brake can be a type of flow brake. 'Assuming that a standard fluid is used as the brake medium, the linear brake curve fb as shown in Fig. 4 It can be applied to the (four) flow brake, but if its purpose is to increase the curve of the force as the angular velocity (1), the parameter is generally sharper, then the non-Newtonian body can be used. The non-bull _ body is not like the Newtonian, the ox_body (four) ship lining constant However, as the shear stress of the fluid in the work increases, the _ cow body is added with speed. These are the well-known anomalous viscous fluids.曰 In the case of a fluid brake, the braking force is generated by the abutment movement of the two interface devices, which is generated by the volume of the fluid that is generated by the coffee. The shear stress is generated in this corresponding to the movement of the braking force, and is provided by splitting the two cavity parts 45 a, 46 a and filling the body, wherein the cavity member 46 a is set to rotate. The component 46, while the other cavity component is disposed on the rotating component that is rotatable relative to the rotating component 46, and the rotating component is connected to the drive shaft 7, the transmission component 7, the Κ 2, 5, or Other elements that can be rotated during the dispensing process cooperatively rotate, and the rotating member 45 can rotate in conjunction with at least the housing 12 or the components that are fixed on the housing 12. Further, the rotating member 45 can be moved axially or axially relative to the housing 12. The sleeve-shaped rotating member 45 can be referred to as a brake housing, and the rotating member 46 is fixed to the sleeve-shaped rotating member 45. As a brake shaft. When the brake is in the engaged state, the semi-fluid cavity 46a axially distributed and surrounding the outer circumference of the brake shaft is equal to the semi-fluid cavity 45a which is axially distributed and surrounds the inner circumference of the brake housing, and further, half The number of the rogue chambers 45a is equal to or less than the number of the semi-fluid chambers 46a. In the combined state, the inner diameter of the brake shell is 45 and the outer diameter of the brake pumping 46 ' in the semi-fluid chamber Zhao 45a In the area of 46a, there is a slight gap that can be dimensioned. Therefore, when the brake shaft 46 rotates relative to the brake housing 45, the fluid will flow into the body _, or no core or equivalent. The gap. The brake housing Zhao 45 can utilize the sliding sealing member 47 to seal the both end sides, so that no fluid can overflow the brake. The sealing member 47 can be in the form of a cap. For example, the cap can be separated from the coupling shaft or combined with the shaft. portion. The advantage of the problem solved by ίΓ is that the angular velocity of the machine is increased so that the braking force is displaced without the _ 'or the effect of the product distribution operation without braking. For example, it is buffered by the product. In addition to the above-mentioned problems to be solved by the present invention, when the high turn: the seat does not increase to a significant level.
