Description

[Detailed description of the invention] Collects medical secretions or fluids And dispose of the suction device Technical field The present invention provides a method for aspirating and collecting secretions and other medical fluids. It has a flexible receiving bag for disposing of the aspirated material under sterile conditions. Regarding suction devices.

Background technology Medical fluids in the hospital, such as urine, drug solutions and secretions during surgery Collection and disposal involves significant contamination risks. For example, store floor bags in the disposal room. emptied and dropped, or placed near the patient and via a release stopper. It is excreted into the receiver. Both processes inevitably contaminate the surrounding air and the caretaker.

Accordingly, as disclosed in German Patent Application No. 2 639 715, Place the container on the secretion flask to receive the drug solution as shown, as well as the hand. Applicable to so-called surgical suction devices used to catch large amounts of secretions during surgery. Ru. In the case of such surgical suction devices, for example, a relatively large receptacle made of glass It is common for the device to be placed on a transportable support frame. like this Once the suction container is full, the entire suction device is connected to the reserve container and The filled container can be emptied by a simple tilt.

Secretion suction flask known from Federal Republic of Toiso patent specification No. 2106631 A flexible/pull receiving bag can be suspended inside the container. There are two in this receiving bag. ducts are open, one leading to the patient and the other producing low pressure. connected to the device.

The intermediate chamber between the bag and the secretion flask is connected to a device that also creates a low pressure. has been done. If the bag is filled or secretion suction is terminated for another reason. As soon as possible, the bag and the intermediate chamber between the bag and the secretion suction flask are ventilated. It will be done. The receiving bag with its contents is then removed from the secretion suction flask and placed in place. If desired, it is dropped after the aforementioned exhaust. A receiver that works according to these principles A secretion suction flask with a bag is further described in U.S. Patent No. 371.91. 97, No. 3780738 and No. 4060107, and widely disseminated. It is known as a commercially available product. Such secretion suction flask by background technology When replacing the receiving bag, the contents of the bag and the suction conduit are exposed to the surrounding air when the bag is removed. Contamination problems arise due to contact with When emptying such a bag, use a floor bag. When emptying, the same gap occurs.

U.S. Patent No. 2,597,715 and No. 350,727 in blood transfusion technology According to Specification No. 8, the patient's blood is removed from a flexible blood bag placed inside a rigid container. It is known to assist in the transfer of blood into the vasculature through the use of gas pressure.

Disclosure of invention The object of the invention is to capture medical liquids in a closed mechanism without contacting the surrounding air. To provide a suction device with a flexible receiving bag that can be collected and disposed of. There are many things.

Solution to the underlying problem of the invention 1. The outer container and the receiving bag placed inside it. A suction device consisting of a suction device is additionally provided with a pressure connection, which It only acts on the outside and this means that the receiver can now read the contents of the bag without having to open the bag. The purpose is to make it possible to take exhaustion into account.

The structure of the present invention includes a suction container and a flexible receiving bag suspended within the suction container. , for example, with a foil bag, the receiver is independent of the bag and the inside of the suction container is connected to the outside of the receiving bag. The connection opening of the additional suction conduit reservoir provided in between and the receiver act on the outside of the bag. and a pressure connection in which the bag is unrolled at its inlet. It is fixedly held in the suction container, and the receiving bag also serves as the connection to the vacuum source and the suction container. Contains duct sump connections to collect and dispose of secretions and other medical fluids. It is a suction device that should be discarded.

Further embodiments of the invention result from the claims.

The present invention proposes two devices configured in relation to the scope of use. A suction device capable of receiving medical liquid and sucking it into the bag is provided without delay. and therefore such devices work in the same way as commercially available surgical suction devices, only In this case, the exhaust from the receiving bag is a combination of the suction container and the flexible receiving bag of the suction device. This is done by adjusting the overpressure in the chamber between the The transfer, regardless of its volume, can take place without contact with the surrounding air. Operator and contamination of the received liquid (e.g. chemical tests cannot be performed without failure). can be avoided) by this.

Now, for example, all floor bags or secretion receptacles for individual patients at the nursing station are The container can be emptied on site under sterile conditions. For this reason, the suction of the aspirator The conduit is equipped with a puncture needle, which allows the floor bag or secretion receptacle to be inserted into the container during puncture. The flask is emptied through the heart (the secretion receptacle with a puncture center is (as described in Federal Republic of Patent Application No. 2820517). now look after Multiple or all floor bags or secretion receptacles at the protection station are Then, the suction device according to the invention is brought into the waste chamber and the suction container and the flexible receptacle are connected to each other. It is emptied by using pressure between the container and the container. liquid to be emptied bodies can be fed directly into the hospital waste conduit, thus giving operators a flexible There is no contact with the contents of the receiving bag.

In short, the device according to the present invention reduces the risk of infection. 2 (3) The floor bag or secretion receptacle is emptied as the container is significantly reduced. things are significantly accelerated.

In addition, the ordinary suction flask that is transported from the patient is attached inside this suction flask. It is modified to accommodate a dust collection bag, and a low pressure is created on the outside of the dust collection bag. By tightening, the suction flask is now ready for work, and on the other side it is placed on the outside of the receiving bag. By creating an overpressure, the contents of the receiving bag are released without being exposed to air, and For example, if the fluid received has been reduced, it may undergo different inspection, and may also undergo special processing, and For example, it is supplied for the production of water-soluble proteins or for the separation of leukocytes, which has recently gained significance. Ru.

Besides the above-mentioned advantages of using the device according to the invention, the receiver is relatively inexpensive to manufacture. This receiving bag can only be used with relatively expensive suction flasks. can be dropped after its use without having to drop it after its use.

The device according to the invention provides a high degree of safety against infection at a relatively low cost. At the same time, hospital staff will be able to reduce the burden of caring for conventional equipment. It will be done.

Embodiments of the present invention will be described below based on the drawings. In the drawing, FIG. 1 shows a first embodiment of the invention, for example when used in a surgical suction device; Figure 2 - shows the configuration of a reservoir stopper that combines with a special component of the bag to receive the individual suction containers. The part is shown enlarged within this range, FIG. 3 consists of a variant embodiment according to the invention for an example of use according to the invention. A suction flask is shown.

In FIG. 1, reference numeral 1 indicates a suction container, which may be made of glass or is made of plastic and is relatively large. Porous inside suction container 1 A supporting wall 2 is arranged, and a chamber is formed between the supporting wall 2 and the wall of the suction container 1. A vacuum or overpressure can be created within the chamber.

In this chamber, for this purpose, there is a suction connected to a pump 4 which creates a vacuum or pressure. The suction and pressure conduit 3 is opened. The suction and pressure line 3 is in this case a single line. It can be formed as a tube or as two separate conduits. In part 5 A closure device for the sump of conduit 3 is shown in the figure, and the closure device prevents the conduit from operating. can be connected to or disconnected from the structure, or thereby Maintaining both overpressure and underpressure in the tube 3 and in the chamber between the suction container 1 and the support wall 2 Can be done.

A receiving bag 6 is provided inside the suction container 1, and the receiving bag is made of foil material. and this makes it possible to insert the suction container 1 through a relatively small opening. can. A suction conduit 7 opens in the bag 6, and the suction conduit goes toward the surgical field. Leads to a vacuum suction device or similar. Furthermore, there is a suction hose inside the receiving bag 6. 8 is open and the suction hose leads to the pump 4.

The suction hose 8 is equipped with a closing member, for example a tightening slider 9, and the suction This area of the pulling hose 8 is made of rubber, for example, and is tightened to support the slider 9. It is interrupted by a connecting member 99 which has a holder. Tightening is done using slider 9. Separating the inside of the receiving bag 6 of the hose 8 from the pump system using a bracket Can be done.

The support wall 2 of the suction container 1 is designed as a perforated wall 10 in the embodiment shown. Therefore, this creates a vacuum in the chamber between the suction container 1 and the support wall 2. When the foil of the bag 6 is inserted through the hole in the porous wall 10, the receiver is inserted into the bag 6. can be brought into contact with the inside of this wall.

Of course, the support wall 2 can in principle also be designed in other ways, for example relatively It is of full-walled design and has only a small opening through which the vacuum acts.

Reference numeral 11 indicates a safety container in FIG. 1, and a suction hose 8 is installed in the safety container. is open and the suction hose 12 is connected to the pump 4 from the safety container. A pressure reducing valve 14 is connected to this connection, and the pressure reducing valve is connected to the inside of the receiving bag 6. and externally optional 8 It is possible to maintain the desired underpressure of , and the necessary overpressure outside the receiving bag 6 . child In this case, the pressure reducing valve 14 has a receiver inside the bag 6 and between the suction container 1 and the support wall 2. The desired degree of vacuum in each chamber is maintained, and for example, the vacuum in the receiving bag 6 is maintained. It automatically operates to lower the vacuum pressure in the intermediate chamber.

The suction conduit 7 is equipped with a member 9a for the rislite type tightening, and the slide In the type fastening, the member is also supported by a rubber hose member 77 that divides the suction conduit 7, Disconnection of the suction line from the system is therefore possible here without vibrations.

As can be further seen in FIG. Open the end of the suction hose 8 deeper. In this case, the suction hole reaching inside the receiving bag 6 The length of the end of the base is at most 1/4 to V3 of the length of the receiving bag. On the contrary, suction The hose 8 is connected to a suction hose 12 that opens into the safety container 11 and into the safety container 11. Open your mouth deeply. With such a configuration, the guide conduit assigned to the pump allows Liquid flowing from the suction conduit 7 into the receiving bag 6 and from the suction hose 8 into the safety container 11 It is guaranteed that mass entrainment is prevented.

From the foregoing description and drawings, it can be seen that the receiving bag 6 is placed inside the suction container 1 by means of the device according to the invention. It can be folded in sections. Furthermore, the vacuum of the bag is the suction container 1 and the receiving bag 6. A vacuum is maintained inside the receiving bag 6 if it is smaller than the vacuum created between it and the outer wall. I can have it. .

The structure of the suction container 1 is not necessarily flask-shaped as shown in FIG. implementation In the example, the suction container 1 can be configured, for example, as an upwardly opening barrel; In this case, the tap 17 is constructed as a correspondingly airtightly mounted cover. . The suction and pressure conduit 3 is connected in addition to the head of the suction container J to the side of the suction container 1. Open to both.

In FIG. 2, the construction of the closure for closing the suction container is shown on a slightly enlarged scale. child In this case, the stopper 17 is fixed to the suction container 1 and seals the suction container 1 against vacuum. Closed.

The upper range of the receiving bag 6 is recognized at the point 6b, and this upper range is the remaining part of the receiving bag 6. The wall is noticeably thicker than the range above, and the brackets make it possible to reach this range. prevent collapse in Furthermore, the upper range 6b of the receiving bag 6 is connected to the suction conduit 7 and the suction port. The connection member of the base 8 is fixedly supported, and therefore, when dropping the bag, this short A new connecting member can be dropped together.

By this, by attaching the stopper 17 to the suction container 1, the suction volume can be confirmed. Vacuum-sealed closure of the container and receiving bag takes place simultaneously.

FIG. 3 shows a suction flask 31 forming the suction container 1a. This suction A receiving bag 6a is placed inside the container 1a, and in this case, the container 1a shown in FIG. It is possible to install a closure device that is almost the same as the one. In the case of such a device, Instead of the unnecessary suction hose 8, a puncture center 36 is provided in the plug 17a.

A raised portion 35 is provided on the outer wall of the suction flask 31, and the raised portion The interior of the container 31 is partitioned off by a support wall 33. The raised portion 35 is at its upper end. It has a puncture center 34 in its part, through which a cannula can be inserted, for example. By creating a vacuum, the cannula is now inside the suction vessel 1a. Inflate the receiving bag 6a attached to the The necessary low pressure has been created inside the receiving bag, which is now passed through the suction conduit 7a. For example, it leads to the area where the drug solution is to be inhaled.

When the suction flask shown in Figure 3 is installed for the wound drain tube, the ridge 35 and thus the puncture center 34 takes over the function of the conduit 3 according to FIG. Bye In some cases, in the area of the puncture center 34, a separate optional device is installed that creates a low pressure. can be connected, since there is no need to keep such ranges sterile. It is the body.

The secretions are collected in a transportable bag, for example, in a suction 7 lasco 31 that can hold 800 mJ. 6a, a receiving bag 6a mounted sealed and closed within this flask. In this case, it is advantageous for this receiving bag 6a to also have a puncturing center 36. 1, and the puncture center is replaced by a suction hose 8 according to the embodiment according to FIG. Becomes 9. At this point, draining and test material are performed during drainage operation. be able to.

Such an embodiment is significantly less expensive than previously known configurations of suction flasks. Savings and at the same time pressure regulation is now possible outside the receiving bag 6a at the low pressure connection or during the puncture. It has the advantage of being done through the mind.
