DE3628966A1 - Medical equipment combination with swab moistener, swab container and mounting - Google Patents

Abstract

In order to facilitate taking blood samples and making injections the invention proposes a small equipment combination with swab dispenser and moistening device which is to be fixed by means of a common mounting and fixing clamp in each case in the most comfortable working position to the wall, shelves and wall cabinets or on instrument trolleys, and offers the following advantages for handling: The swab container is designed as a dispenser and contains the cellulose swabs required in everyday practice on a small swab roll in which the swabs can be stored hygienically and can be removed separately. The moistening device has a new design and is provided with a double valve for the metered removal of liquid, so that the swab can be selectively moistened on the upper side or on the lower side of the device. The common double mounting has a square cross-section and permits use of both devices in such a way that they can also be operated from the front irrespective of whether installation is on the left or on the right. With a worktop or a double holding clamp the two devices are an ideal set which can also be fastened on the work table, on shelves or on the wall cabinet for syringes and cannulas. <IMAGE>

Description

Before taking a blood sample or injection the area of the puncture site is disinfected. This is usually done using a pulp swabs previously on a swab moistener with alcohol was soaked. These cellulose swabs are 1000 each Pieces are prefabricated in relatively large rolls and are in medical practice u. in the hospital in container nissen, which is stored in a device cabinet brought or directly to a closet Removal of individual swabs are placed.

What is needed to moisten the swab removed The humidifier is usually not located immediately next to these storage containers, which is a rational Working style difficult; especially when injections or taking blood in other practice rooms or on Patient bed must be performed.

With this protection application a Device combination suggested that from a small Storage container for swabs and a newly designed one Humidifier exists. Both devices preferably have the same footprint and are in a common Bracket combined into one unit. These Bracket can be optionally on wall cabinets and shelves, as well as being mounted on the mobile equipment trolley, so that even in adjoining rooms and at the bedside rational way of working is possible.

The small storage container for swabs as a sub-device this unit contains those for everyday practice requires the required number of cellulose swabs and is for easier removal of individual swabs as a dispenser educated.  

The humidifier was compared to commercially available Devices improved so that it as a wall and floor unit is to be used, on which the swab both on the upper side and on the underside of the device can be. With this new, improved construction tion was reached at the same time, the entire volume of the device, whereas the commercially available Devices of a similar type are only used to around 60% and are therefore uneconomical.

This improved and very easy to manufacture Swab moistener essentially consists of one shoe - shaped hollow body, whose upper cavity in the lower cavity underneath seamlessly transforms; namely in the lower cavity, which with the commercial devices only for sub bringing the valve with housing and as a stand is used.

The liquid flows from the upper cavity - as with the commercial devices - directly to the upper valve, which is placed next to the base of this cavity is; whereas on the lower valve of the improved device the liquid can be removed from both cavities can.

Both valves of the improved device are inside of the front part of the device and stand aligned on top of each other. They form that at the same time Counter bearing for a common coil spring, so that special valve housings are no longer required.

On the other hand, there is the possibility of the upper valve with a suction u. Pressure piston and an elastic Combine the riser pipe in the same way as in the registration dated 29/1/86 P 36 02 556.9 / G 86 02 150.8 beat and described so that this valve too the liquid can be removed from the entire device can.

The main design features of these devices combination are from the drawn examples visibly; and shows

Fig. 1 dimensional representation of the combination of devices consisting container from the shoe-shaped Tupferanfeuchter A and which is designed as dispenser swab B, both of which are summarized as equipment unit in a common holder C,

Fig. 2 A partial section of the Tupferanfeuchters with holder C which can be extended to the stator 18,

Fig. 3 shows a longitudinal section of the swab dispenser B, the C in the holder can be suspended and, in addition be combined with a table clamp 14,

Fig. 6 a longitudinal section of a cuboid Tupferbefeuch ters A and B with attachable swab container holder C / 14,

Fig. 7 section through a screw cap 21 with an internal valve body 24/25 .

In the figure according to FIG. 1, both devices A, B are shaped approximately the same and are hung in the common wall holder C. The footprint of both devices A, B together corresponds to a square, so that they can be implemented with a side wall mounting within the holder C for the most convenient handling by 90 degrees to the left or right. The angular shape of all individual parts A, B, C also allows space-saving placement; just as it is possible to hang each of the devices A, B on its own in a halved holder C and to arrange them side by side or one above the other, the shoe-like device shape favors the handling of the devices even if both devices A / B in their Individual bracket C are mounted directly one above the other!

In Fig. 2, the humidifier A consists of a closed, shoe-shaped hollow body 1/2 , the upper, preferably obliquely offset hollow space 1 extends to the upper valve seat 3 and merges seamlessly into the lower cavity 2 , on the underside of which the second Valve body 4 is arranged.

Both valves 3, 4 are located in the front shoe and lie there axially one above the other within the recessed wall. They also form the counter bearing for the common coil spring 5 . For better guidance, the valve bodies 3, 4 and both ends of the spring 5 are each in a cylindrical sleeve 6 , which are connected in one piece to the respective device wall and have lateral, very narrow inlet slots 7 , which allow a relatively small dose of liquid to be withdrawn.

The valves 3, 4 have an additional, elastic sealing disc, which preferably consists of the resistant silicone and together with the conical valve seat ensure a permanent seal.

The sunk on the top of the shoe's valve 3 is covered from above by a hinged to the housing dust cover 8 , which rests in the closed position on the front edge of the device up to the front edge of the two cams 9 mounted on the side, in such a way that it is used to draw liquid between the two Fold up cam 9 with your finger. The front u. Rear arranged cams 9 also serve as a support within the wall bracket C , which is extended in one piece down to the base or to be used in a non-slip and correspondingly heavy base plate 18 with side cheeks. The underside of this base plate 18 can additionally be provided with double-sided adhesive tape.

Approximately in the middle of the front housing wall is preferably arranged a catch 19 which securely fixes the housing within the holder C when removing liquid from below.

If the humidifier A is combined on its underside with an equally wide, additional bracket 14 - as shown in FIG. 3 - there is the possibility of hanging the humidifier A either in a wall holder C or in a shelf so that any one can be used Location selection is possible in such a way that the liquid can be removed at any time from above and / or on the underside of the device. In addition, the table clamp 14 can be firmly glued to the housing of the device or connected to it in one piece; just as it is possible to slide the clip 14 onto the device A by means of a guide bar.

Another variant consists in combining the upper valve 3 with a suction and pressure piston together with a flexible riser pipe, so that the liquid can also be removed from the entire hollow body 1, 2 via the upper valve.

As shown in FIG. 4, a filler neck 29 with a screw cap is arranged on the top of the container.

The device in Fig. 3 represents a swab container B , in which a prefabricated, small, single-row swab roll is used and on the underside of individual swabs are removed up to a total of about 50 pieces.

In contrast, the relatively large, commercially available swab rolls usually around 1000 Swabs that are double-chained together by knobs and from which the required swabs are torn off individually will. There are big ones for these bulky ones Roll a large removal box or a correspondingly large one  Divisions in closets that make up the Swabs out in pairs from the end of the roll are drawn so that when removing only one if the swab is needed, the second one remains at the end of the roll swabs sticking outwards and until later Removal remains exposed to dust. A take away these large swab rolls into other treatment rooms is of course impractical. You also have to go riding multiple injections or taking blood samples each several individual swabs torn off and in open ones Containers are stored and transported. But this way of working is also cumbersome and unsanitary.

In this respect, the proposed new swab dispenser B offers considerable advantages; because the width of the dispenser B is the width of a single swab measured. In addition, the dispenser B holds at least the number of swabs required for the daily needs of a doctor's office, which is used as a finished roll from the open front side in the device B. For this purpose, the device B consists of the bottom and rear wall with two side walls of the same shape, which correspond approximately to the side profile of the shoe-shaped dampening device A. For resting in the wall holder C , the knobs 9 are in this example designed as cross bars, of which the cross bar is connected to the two side walls on the front of the device to stabilize the device. The material strip 10 which can be hooked into the device opening from above has the swab width and is intended as a transparent cover, with the simultaneous function as a hold-down device for the swab to be removed from the underside of the device. This cover strip 10 is angled in the upper part - according to the profile of the side walls - and runs approximately halfway up either vertically downwards or - as drawn - obliquely downwards, where it runs out in a beak shape ( 11 ) and rests with this end piece 11 directly on the bottom of the container . The upper, rear end of the cover strip 10 , which runs there approximately horizontally, is designed as a clip 13 and is thus suspended in the rear wall of the container; such that the beak-shaped lower part 11 of the strip 10 rests on the bottom of the container with some pretension. This has the effect that, when the swab is removed, the swab roll to remain within the container B together with the cover strip 10 are not pulled out to the front; with the further effect that the low contact pressure of the cover strip 10/11 is sufficient to lightly clamp the next swab at its front tear-off point with the beak edge of the end piece 11 when a swab is pulled out, so that the next swab always remains in the removal position.

The thumb-wide recess 12 can either be arranged on the container bottom and / or on the lower portion of the masking strip 10/11 , but in such a way that the swab lying below the beak-shaped strip end 11 rests at least on the two remaining side flanks on the container bottom. On the upper side of the cover strip 10 , an additional grip strip can be formed with for easier removal of the strip; just as it is possible to form the upper edge of the rear wall of the container into an upwardly open bracket 13 , into which the angled end of the strip 10 is inserted with a little bias.

The loose clip 14 shown in FIG. 3 below the device B can be glued to the bottom of the container by means of double-sided adhesive tape, so that the swab dispenser B can optionally be inserted into a wall bracket C or into a shelf; just as this device can also be combined with a stand.

If the clamp 14 is made in double container width, moistening device A and swab dispenser B can be used as an ideal set either in a double holder C or on a shelf. There is also the option of mounting both containers A / B with a full or halved bracket C on a mobile ambulance.

In Fig. 4, a humidifier A is shown with a clip 14 formed in longitudinal section. The individual components and the function of the device are essentially the same as shown in FIGS. 1 and 2. The horizontally drawn, dotted line at the height of the upper valve 3 corresponds to the plane which represents the imaginary boundary between the seamlessly superimposed cavities 1, 2 . The inner pins of both valve bodies 3, 4 lie within the common coil spring 5 , which in turn is guided in a cylindrical pipe section 15 . This tube 15 is on the edge of the lower valve body 4 loose and easy to slide ver, such that the axial clearance upwards between the tube 15 and valve body 3 corresponds to at least one stroke length. A perforated disc made of silicone is provided as an elastic valve seal. The ver lowered filler neck 29 on the top of the device is loosely closed by means of a screw cap and thus serves at the same time for venting the device, which together with clip 14 in a single or double holder C , or - as drawn - can be pushed onto a shelf.

Fig. 5 shows a simple, rectangular and upwardly open container B , which is intended in this form to accommodate loose swabs and has the same footprint as the previously described individual devices A, B , so that this container (instead of the dispenser. Fig. 3), combined with the humidifier A , in the same wall bracket C or - by means of the bracket 14 - can be used in a shelf. The hinged protective cover 8 serves to cover the cellulose swabs loosely placed in the container, which are held in their vertical position by the longitudinally sliding partition 17 - even with a small amount of fill.

In Fig. 6, the humidifier A consists of a single, rectangular hollow body 20 with filler neck and screw cap 21 , in which a valve according to FIG. 7 is concealed. For use as a moistening device with the removal of liquid from below, the hollow body 20 is hung with the closure cap 21 directed downward into a wall holder C , on the rear wall of which a bracket 14 is integrally formed, so that the device A / C can be either on a wall or on a shelf can be attached. With the integrally formed cams 9 together with the catch 19 , this container A can also be suspended in a halved holder C (without the clip 14 ). There is also the possibility of a simple swab container B with the same footprint - e.g. B. detent - to put on the moistening device A or stick it on easily, so that swab container B and moistening device A are arranged in a halved holder C as an ideal combination directly above each other. - Since the swab container B is provided on both ends with cams 9 , the devices A / B can also be placed next to each other within a double holder C , so that a versatile combination nation is possible. For the rest, it is recommended that this cuboidal moistening device A shown in FIG. 6, together with filler neck and knobs 9, be made in one piece from plastic, for which the very inexpensive vacuum process is suitable. In this method, however, it appears advantageous to top up the cavity 20 and thus the container A by - as indicated in the drawing by the dashed wall - cranking out the wall surfaces of the front and rear so that the device A - Instead of the knobs 9 - by means of these offsets lies directly on the wall bracket C.

In Fig. 7 the screw cap 21 is shown approximately in natural size. When screwing onto the filler neck of the container A according to FIG. 6, this is sealed by the molded sealing ring 22 . On or in this sealing ring 22 , a perforated disc or a cylindri cal capsule 23 is pressed, which is preferably made of an elastic material such. B. silicone and seals the sealing ring 22 upwards. The perforated disc or the perforated bottom of the capsule 23 is slightly curved inwards. concave. This ent ent within the sealing ring 22 or within the capsule 23, a cylindrical cavity in which a spring-loaded valve body 24 is mounted with lateral play, the plunger 25 protrudes into the bore of the spout 26 and rests there on the pin 28 until this pin 28 before using the device on the external marking resp. Ring nut 27 is separated.

In the closed position according to FIG. 7, the perforation of the inwardly curved silicone capsule 23 is covered by the upper side of the valve body 24 which is pushed up. After the lower pin 28 has been removed, the plunger 25 , which is under spring pressure, emerges from the now open spout 26 . At the same time, the valve body 24 designed as a cone valve comes into the closed position - due to the compression spring - and thereby opens the opening of the silicone capsule 23 , from which - supported by the suction effect of the valve body 24 - liquid can flow from the container A 20 into the cylinder space.

If the plunger 25 projecting freely downwards is pressed upward, the liquid located inside the capsule 23 flows out downwards. The valve body 24 thereby pressed up simultaneously closes the relatively small opening of the capsule 23 until the contact pressure on the tappet 25 ends and the plug valve is closed again. This a simple pumping process causes the liquid to be removed from the humidifier A in small amounts.

To fill the container A according to FIG. 6, it is removed from its holder C , then closed with the screw cap 21 and, as in FIG. 6, placed upside down in the holder C.

Since this cuboidal moistening device A preferably consists of polyethylene and can be produced very easily in a vacuum process, there is the further advantage of using this container together with the filling and closure 21 as a disposable item.

Since the long sides of each individual device A / B correspond to twice the device width, a square footprint results for two devices A / B placed side by side, which again corresponds to the inside width of the holder C. Furthermore, each individual device A / B can also be used in a halved holder C and / or combined with a holding clip 14 , so that this device combination can be ideally adapted to the available space of a medical practice. In addition, the individual and overall dimensions of the above device combination A / B together with their holder C correspond exactly to the size and footprint of the disposal boxes and their holder according to the registrations of May 30, 86/18. 6. 86 (P 36 18 167.6 / G 86 14 635.1 and P 36 20 445.5 / G 86 16 304.3), so that with the present innovation a complete, space-saving device system is available.
