    • A method and an apparatus for applying an anesthetic includes a receptacle having an upper end, a substantially hollow interior, a lower end having a tube or nozzle extending therefrom, and an attachment for attaching to the barrel of a syringe or vice versa. The receptacle receives a container or canister containing an endothermic gas or vapor (propellant) that rapidly absorbs heat when released to the atmosphere. A depressible actuating member or trigger propels the gas or vapor through an outlet nozzle that is oriented to project a stream of gas or vapor along a delivery axis that intersects a delivery axis of the needle, therefore, the gas or vapor can be successively delivered to an injection site with minimal repositioning of the housing.
    • 用于施加麻醉剂的方法和装置包括具有上端,基本上中空的内部的容器,具有从其延伸的管或喷嘴的下端,以及用于附接到注射器的筒体或反之亦然的附件。 容器接收容纳或释放含有吸入气体或蒸气(推进剂)的容器或容器,其在释放到大气中时迅速吸收热量。 可压下的致动构件或触发器通过出口喷嘴推动气体或蒸气,出口喷嘴被定向成沿着与针的输送轴线相交的输送轴线突出气体或蒸气流,因此,气体或蒸气可以连续输送到 一个注射部位,最小的重新定位。

    • A method and an apparatus for applying an anesthetic include an elongated tubular housing having an upper end, a substantially hollow interior, and a lower end having an injection needle extending therefrom. A first chamber is formed within the housing interior for holding an anesthetic cartridge therein. A second chamber receives a cannister containing an endothermic gas that rapidly absorbs heat when released to the atmosphere. The cartridge is penetrated by a plunger that forces the anesthetic through the injection needle. A depressible trigger propels the gas through an outlet nozzle that is oriented to project a stream of gas along a delivery axis that intersects a delivery axis of the needle; therefore, the gas and anesthetic can be successively delivered to an injection site with minimal repositioning of the housing. Accordingly, a dental practitioner can initially disperse the endothermic gas onto the injection site to minimize any pain and discomfort associated with an injection. Subsequently, the practitioner inserts the needle into the deadened site and injects the anesthetic.
    • 用于施加麻醉剂的方法和装置包括具有上端,基本上中空的内部的细长管状壳体和具有从其延伸的注射针的下端。 在壳体内部形成第一腔室,用于将麻醉药筒保持在其中。 第二个室接收一个含有吸收气体的罐,当吸入气体释放到大气中时,该吸热气体迅速吸收热量。 药筒穿过迫使麻醉剂通过注射针的柱塞。 可压下的触发器通过出口喷嘴推动气体,所述出口喷嘴定向成沿着与针的传送轴相交的输送轴突出气流; 因此,气体和麻醉剂可以以最小的壳体重新定位连续输送到注射部位。 因此,牙科医生可以最初将吸热气体分散到注射部位以最小化与注射相关的任何疼痛和不适。 随后,从业者将针插入到减压部位并注射麻醉剂。
