This invention relates to surgical devices, and more particularly to a surgical device designed for use in the transfusionofblood, an important object of the invention is to provide a device of this character which will measure the blood passing from the donor to therecipient, in such a way that the blood stream is subjected to the minimum of contact or disturbance, without mechanical injury toits constituents, by avoiding subjecting the bloodto excessive suction, intense pressure, friction o r impact, and having temperature maintained. -f

A further object of the invention is to provide a device to carry out the transfusion of blood in such a way that the rate of blood flow from the donor to the recipient may be observed and controlled, and the air suction and pressure which respectively providethe above eects, are maintained uniform, accurately observable, and instantly adjustable, and that the cycle of transfusion is .quickly eected with practically no eifort on the part Vof the operator.

'Another object of the invention is the provision of a. device wherein the parts in blood contact are few, simple, easily taken 4apart for sterilization and coating with paraffin. A still further object of theinvention is to provide a' machine which is portable, silent in operation, and one -which is particularly adapted for accomplishing the purpose for which it vhas been invented.

Withthe foregoing and other objects in vie-w,`which will appear as the description proceeds, the invention resides in the combination andV arrangements of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed, may bel made Within the scope of what is claimed, vwithout departing from the spirit of the invention.

Referring to the drawings in detail, the device comprises a base indicated generally by the reference character 5 and on which the mechanism constituting the surgical device, 1s supported.

The reference character 6 designates an electric motor, which is supplied with suitablel gearing not shown, for operating the pump indicated by the reference character 7 The pump includes a piston 8 and piston rod 9, which is eccentrically connectedto lthe wheel 10 of the gearing, as at 11. Disposed 8- at one end ofthe pump 7, is` ablock 12 which a is provided with an upper passageway 13 and a lower passageway 14, the passageways 13 and 14 adapted to register with the

arcuate grooves

16 and 17 respectively, formed in the valve member 18. This valve member 18 is rotatably supported within the housing 19, and is held into close engagement with the VVblock 12, by means of the coiled springsQO,

there being provided an operating lever 21, 92 for operating the valve member 18, to control the passage of air through the passageways 13 and 14.

An opening 20 extends through the valve member 18 and is adapted to register with the opening 13, when the mechanism is running idle.

As shown, by Figure 1 of the drawings, a filtering head 22 is provided, and is secured adjacent to the lower passageway 14, so that air drawn into the passageway 14 will be purified, before entering the measuring vessel of the device.

Supported within the block 12 and disposed on opposite sides of the passageways 13 and 14, Vare valve members 23 and 24respectively. A passageway is provided in the valve member 23 and extends through theA valve member 23, the passageway being provided with a valve seat intermediate its ends, against which the ball valve 26 seats. A coiled spring 27 engages the bal-l valve 26 and normally acts to urge the ball valve 26 to its active position, to prevent the yair pressure in the tank, from returning to the pump cylinder. This spring 27 is held in place by the threaded cap 28. The valve member 23 acts to control the action of the air as tbe air is being forced into the measuring vessel of the device, to be hereinafter more fully described.

The valve member-24 is provided vwith a passageway 29 that extends therethrough, there being' provided a ball valve 30 for controlling the passage of' air through the valve member 24. Thisball valve`30 is held to its seat by means of the coiled spring 31 which in turn is held in position by the screw 32.

It will beobvious that Vthe valve member 24 is so arranged that the suction created by the piston 8 will act to create a vacuum in y the measuring vessel. n

A combined vacuum relief valve and pressure relief valve forms a part of the device, and includes the body portion 34 formed with an extension pipe 33 through which the body portion is in communication with the passageway 13. i

The body portion 34 has bores 35 and 36 respectively, the bores 35 and 36 being provided with valve seats for the reception of the valves 35 and 39 respectively which are normally held to their seats byv means of the coiled springs and 41 respectively, that in turn are'tensioned by the adjusting screws 41.

Thebore 36 communicates with the atmosphere through the opening 38, the opening 38 being normally closed by thebore valve '39 which is held to its seat by the spring 40 and adjusting screw 41.

In order that the pressure in the measuring vessel or tanl; may be readily determined, a pressure gauge indicated at 42 is provided.

Communicating with the bores 35 and 36, is a pipe 43 that leads to the measuring vessel 44, that has itsinner surface coated with paraffin and which is in the formof an inverted bottle having graduations provided thereon, to indica-te the contents o-f the measuring vessel.

As clearly shown by Figure 2 of the drawings, the mouth of the measuring vessel or tank is removably held in the support 45 which in turn is formed with an extension 46 also removably fitted in the socket member 47, rising from the base 5.

Extensions

48 and 49 `respectively extend from the support 45, and to which the tubes 50 and 51 o respectively are connected, the tube 50 leading to the donor of the blood, while the tube 51 leads to the recipient. l A. valve 52is mounted in an opening of the support, and is provided with an opening adapted to establish communication between either

tube

50 or 51 and the measuring vessel,`so thatiluid may be drawn into the measuring vessel, through the tube 50,- and exhausted therefrom, through tube 51. y

Link 53 connects the valve and lever 21, so that movement of the lever 21,to lset the valve member 18 for producing a vacuum` or pressure in' the measuring vessel, will cause a relative movement of the valve 52, t0 correspondingly setthe valve 52.

An electric lamp indicated bythe reference character 56.*is mounted kadjacent to the measuring vessel, to maintain the tem perature of the blood, and `make Visible the level of blood within the measuring vessel.

Formed inthe valve 18, is an o Lening-20 which is brought into registry wit the passageway 13 to establish'V communicationfbetweenv the vessel and atmosphere to exhaust air from the vessel.

Passagewavs 55 are also provided in the block 12 and establish communication .i between the valve member18 and atmosphere, lthrough the

passageways

25 and 29, therefore, Yshould it be desired to'operatefthe device ina neutral position, by turning the f valve member 18 Vto aposition as shown' by Figure 5, air will be drawn into the valve member 18 on one stroke of the piston, and exhausted onthe return stroke thereof.

Should it be desired to create a vacuum in the measuring vessel to draw blood into the vessel, the valve member 18 is moved to a position as shown by Figure 6, whereupon yair. is drawn through the upper passageway 13,'y through the valve 18and exhaustedl through passageway 29. vWhen a suiicient quantity'of blood has been drawn'V into the measuring vessel, thev valve 18 is operated to cause the groove 16'to register with' the Vpassageway 13 and groove 17 with passageway 25V, asvshown by Figure 7. The'action of the piston 8 will now act to compress'air ifn the measuring vessel to force Ablood thererom.

From the foregoing it will be obvious that f duced in the vessel 44, the valve- 37 Will be raised against the tension of the spring llk relieving excessive pressure Within the vessel 44.
