   PERFECTIONNEMENT AUX AMPOULES AUTO-INJECTABLES EN MATIERE   P LASTIQUE.   



   L'invention se rapporte aux ampoules auto-injectables en matiè- re plastique, afin de perfectionner à la fois les moyens d'utilisation et les moyens de fabrication de ces ampoules.. 



   Il est connu que dans les cas d'urgence, tels que -syncopes cardiaques, - piqûres venimeuses, - cas de secours hors de présence d'un service de santé (exploration, sport, guerre), il est nécessaire d'effectuer très rapidement une piqûre pour laquelle, avant la création des ampoules auto-injectables, il convenait   d'employer :   - une seringue, - une aiguille, - une ampoule, - un appareil de stérilisationo 
Du groupage de ces éléments, il résultait des difficultés et des pertes de temps dues aux conditions d'incommodité.   L'ampoule   auto- injectable groupe tous les éléments pour faire une injection hypodermique sans faire appel à des éléments extérieurs et dans un temps minimum. 



   L'invention a pour but d'apporter aux réalisations existantes des perfectionnements certains. 



   Un exemple de réalisation préférée de l'objet de l'invention est décrit ci-après avec référence aux dessins annexés, dans lesquels : 
Figure 1 est une vue en coupe longitudinale d'une ampoule selon   l'invention   
Figure 2 est une vue en coupe transversale suivant la ligne   Il-Il   de figure 1. 

 <Desc/Clms Page number 2> 

 



   Gomme montré en figure 1, la fixation de l'aiguille m est pré- vue sans embase. Le tube de l'aiguille est, comme montré en m', mandriné strié ou molleté à sa base, de fagon à assurer une bonne retenue dans la matière plastique, à des conditions beaucoup moins onéreuses que l'aiguil- le avec embase dont la fixation offre des difficultés certaines. 



   En outre, l'extrémité effilée de l'aiguille pénètre en profondeur dans un logement élastique du capuchon c, dont le diamètre intérieur est lé- gèrement inférieur au diamètre extérieur du tube d'aiguille et recouvre celui-ci sur une grande partie. Il en résulte une étanchéité absolue et la compression de l'air contenu dans le haut de l'ampoule empêche toute pénétration de liquide dans   l'aiguille.   Le logement de la partie effilée de l'aiguille peut se faire soit dans le matériau même de l'ampoule a, soit dans un matériau similaire b souple ajouté dans le fond du capuchon 
Pour faciliter le moulage des parties minces de l'ampoule, des nervures longitudinales n (dans le sens de l'injection) sont prévues en nom- bre suffisant pour la bonne alimentation des pièces sans nuire à la souplesse* 
Dans le même but,

   sur la base circulaire destinée à être pincée pour la soudure s, un   cordon o   est ménagé, ce cordon a le gros avantage de donner un apport de matière pour les soudures devant se faire au chalumeau en raison de la nature du matériau employé. C'est le cas d'un matériau tel que le polyéthylène dont l'angle de perte à haute fréquence ext   extrê-   mement faible et ne permet pas la soudure électrique en profondeur. 



   Bien entendu, l'invention n'est pas limitée aux dispositions dé- crites ci-dessus; elle embrasse toutes les variantes basées sur les mêmes principes. 



   REVENDICATIONS. 



   Ampoules auto-injectables en matière plastique, offrant les caractères suivants,pris séparément ou en combinaison : 
1) Le tube d'aiguille est fixé lors du moulage ou à chaud di- rectement dans la matière plastique sans interposition d'embase. 



   2) L'extrémité effilée de l'aiguille est capuchonnée d'une manière étanche par le même capuchon que celui qui s'adapte sur la par- tie extérieure de l'ampoule. 



   3) Des nervures de renforcement sont pratiquées pour la bonne venue du moulage des pièces sans nuire à la souplesse.

   IMPROVEMENT OF SELF-INJECTING BULBS IN P LASTIC MATERIAL.



   The invention relates to self-injectable plastic ampoules, in order to improve both the means of use and the means of manufacturing these ampoules.



   It is known that in emergency cases, such as cardiac syncopes, - poisonous bites, - emergency cases outside the presence of a health service (exploration, sport, war), it is necessary to perform very quickly an injection for which, before the creation of the auto-injectable ampoules, it was necessary to use: - a syringe, - a needle, - an ampoule, - a sterilization device
The bundling of these elements resulted in difficulties and loss of time due to the conditions of inconvenience. The self-injectable ampoule groups all the elements to make a hypodermic injection without calling on external elements and in a minimum of time.



   The object of the invention is to bring certain improvements to existing embodiments.



   A preferred embodiment of the subject of the invention is described below with reference to the accompanying drawings, in which:
Figure 1 is a longitudinal sectional view of a bulb according to the invention
Figure 2 is a cross-sectional view along the line II-II of Figure 1.

 <Desc / Clms Page number 2>

 



   As shown in figure 1, the attachment of the needle m is provided without a base. The tube of the needle is, as shown in m ', mandrel ridged or soft at its base, so as to ensure good retention in the plastic material, at much less costly conditions than the needle with a base whose fixing offers certain difficulties.



   Furthermore, the tapered end of the needle penetrates deeply into an elastic housing of the cap c, the inner diameter of which is slightly less than the outer diameter of the needle tube and covers the latter over a large part. This results in an absolute seal and the compression of the air contained in the top of the ampoule prevents any penetration of liquid into the needle. The housing of the tapered part of the needle can be made either in the material of the ampoule a, or in a similar flexible material b added in the bottom of the cap
To facilitate the molding of the thin parts of the bulb, longitudinal ribs n (in the direction of injection) are provided in sufficient number for the correct feeding of the parts without compromising flexibility *
For the same purpose,

   on the circular base intended to be clamped for welding s, a bead o is provided, this bead has the great advantage of providing a supply of material for the welds having to be done with a torch because of the nature of the material used. This is the case with a material such as polyethylene, the angle of which at high frequency is extremely low and does not allow in-depth electrical welding.



   Of course, the invention is not limited to the arrangements described above; it embraces all variations based on the same principles.



   CLAIMS.



   Auto-injectable ampoules of plastic, exhibiting the following characteristics, taken separately or in combination:
1) The needle tube is fixed during molding or hot directly in the plastic material without interposition of the base.



   2) The tapered end of the needle is tightly capped by the same cap that fits on the outer part of the ampoule.



   3) Reinforcing ribs are made for the good coming of the molding of the parts without compromising the flexibility.

** ATTENTION ** end of DESC field can contain start of CLMS **.


    

Claims (1)

4) Une nervure de base assure un apport de matière dans la ligne de soudure lorsque celle-ci doit se faire au chalumeau. **ATTENTION** fin du champ CLMS peut contenir debut de DESC **. 4) A base rib ensures a supply of material in the welding line when this must be done with a torch. ** CAUTION ** end of field CLMS may contain start of DESC **.
