This invention relates to surgical spray devices, and more particularly to a portable mechanism adapted to be employed as a vaginal douche in conjunction with bottled carbonated water.

A main object of the invention is to provide a novel and improved surgical spray mechanism which is simple in construction, which is adapted to be employed with conventional carbonated water bottles, and which is designed for direct application and use with bottles in which carbonated water is widely sold.

A further object of the invention is to provide an improved vaginal douche mechanism which is inexpensive to manufacture, which is reliable in operation, which automatically regulates the pressure of the carbonated water employed with the device, and which is very easy to manipulate.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

Figure 2 is a top plan view of the structure of Figure 1;

Figure 7 is a cross-sectional detail view taken on the line l'| of Figure 1;

Figure 8 is an enlarged perspective view of the valve plunger employed in the surgical spray device of Figures 1 to 7.

Referring to the drawings, the surgical spray device-is designated generally at I I and comprises a head member I2 of suitable rigid material, such as plastic material, having secured thereto the elongated, curved, spray tip I3 of similar rigid material. The head I2 is provided with a sleeve portion I4 defining a cavity l5 adapted to receive the mouth portion of a conventional carbonated water bottle I 6 in the manner shown in Figures 1 and 3, the sleeve member I4 being formed at its rim with diametrically opposed, inwardly extending gripping lugs I'I, I1, and being divergently slotted at I8, t8 adjacent each inturned lug IT to provide a degree of resiliency for the gripping lugs I! and to enable said lugs to snap over the usual curved mouth portion I9 of a bottle to secure the mouth of the bottle in the sleeve portion I4.

Designated at 2B in an annular bulb of elastic deformable material, such as rubber or the like, said bulb being formed with the annular base flange 2| which is received in the bottom of the sleeve portion I4 and which is clampingly engaged I by a fiat, C-shaped, resilient ring 22 seated in an annular groove 23 formed in the lower portion of the interior wall surface of sleeve member l4, said ring 22 exerting clamping pressure on the annular flange 2| and tightly securing the bulb 20 in axial position in the cavity I5. Designated at 24 is a plunger having an enlarged body portion 25 and a stem portion 26. The plunger 24 is arranged coaxially inside bulb 2!} with the stem portion 26 extending slidably through head I2, as shown in Figure 3. Said head is formed adjacent th enlarged body portion 25 of the plunger with a cylindrical cavity 27 allowing plunger 24 to reciprocate along its axis. Secured to the end of the stem 23 is a button element 28, and surrounding the stem 26 and bearing between button element 28 and head I2 is a rubber spring washer 29 biasing the plunger 24 downwardly, as viewed in Figure 3. Downward movement of the plunger 2:1 is limited by the shoulder 30 defined at the end of enlarged portion 25. Axially secured to the top end of the enlarged portion 25 is a rod 3| having secured to its end the valve element 32 adapted to seat on the end of the annular bulb 20, the rod 3| extending through an opening 33 formed in the tip of the bulb. As shown in Figures 3 and 8, the main body portion 25 of the valve plunger is formed with the

longitudinal flutes

34, 34.

Ihe spray tip I3 is formed with the passage 35 which communicates with a passage 36 formed in the head i 2 and which connects passage 35 to the cavity 21 of said head.

In using the device, the head I2 is first engaged over the mouth of a bottle I 6 of carbonated water, the bottle mouth being received in the cavity I5 and being lockingly engaged by the gripping lugs I1, I! in the manner above described, the bulb 20 being received inside the bottle mouth. The pressure of the carbonated water acts on the valve element 32, and said pressure combines with the biasing force of spring 29 to cause the valve element 32 to seat on the bulb tip and exert substantial compressive force on the bulb. The compressive force of the valve element 32, acting axially on the bulb 20, causes said bulb to expand laterally against the inner surface of the bottle mouth and to sealingly engage said inner surface, as well as exerting clamping force thereon relative to the adjacent external portions of the sleeve I4. It will be noted that the pressure of the carbonated water. acts on the side surfaces of the bulb 20 as well as on the valve element 32, and tends, to some degree, to oppose the lateral expansion of said bulb produced by the compressive axial force imposed on the bulb by valve element 32. Said axial force is provided by the combined efiect of the spring 29 and the pressure inside the bottle. If, however, the pressure inside the bottle is excessive, it will be sufiicient to prevent the valve element 32 from sealingly engaging he tip of the bulb, and hence, will allow the gas under high pressure to escape from the bottle through opening r a i 21, passage 3 n p sa 35,. unt l 3 the pressure has diminished sufficiently to allow valve element 32 to seat on the tip of the bulb.

In using the device, the button element 28 is pushed inwardly, causing the valve element 32 to be elevated with respect to the tip 2|] and to allow the carbonated water to pass through opening 33, cavity 27, passage 36,and passage 35, and

to issue from the tip of the nozzle E3 in the form of a spray.

It will be noted that when the spray device is attached to abottle, the bulb 2c is narrowed and elongated by depressing the button element 28, the end of the enlarged body portion 25 of the valve plungerengaging the tip of the bulb and causingsaidbulb to be stretched and narrowed. This allows'the clamping lugs H, H 'to'snap past thecurved portion it of the bottle neck as the sleeve I4 is engaged over theneck of the bottle. Releasing the button element then allows the bulb to assume its normal shape, thereby sealing the bottle opening and at the same time allowing the valve element 32 to sealingly engage the tip of the bulb 2t and close the opening thereof. As above explained, whenever the pressure in the bottleexceeds a'predetermined value, said pressure acts on the bulbzc until the bulb is distorted to such a degree that the valve element 32 no longer seals the opening $3, allowing the gas underlhigh pressure to escape through the device 'until the'pressure drops sufiiciently to allo'wthe tip ofthe bulb to be engaged by the valve element 32. The limiting value of pressure may bereadily adjusted by employing a suitable length of the valve plunger, and more particularly, by adjusting the length between shoulder .30 and valve element '32.

After the mechanism has been attached to the carbonated water bottle, as above described, and after the excess pressure has been released automatically, as above explained, the spray nozzle tip [3 is inserted into the vagina and the release button 28 depressed, allowing the contents of the bottle to be discharged.

The action of the'ga escaping from the bottle l6 may be made more rapidand may be made more active by agitating the bottle it after the spray attachment has been secured thereon.

While a specific embodiment of an improved surgical spray device has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of themvention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by'the scope of the appended claims.
