Definitions
- the present invention relates to a medical connector with automatic sealing during disconnection and a method for connecting or disconnecting a medical connector.
- a typical application is that patients are usually given a fixed access when they are admitted to the hospital. This access is opened for the supply of liquid medical solutions by removing a closure cap and then establishing a corresponding fluid connection.
- a common, standardized type of connection is the Luer connection.
- the patient access (vascular access, peritoneal access, etc.) remains on the body and germs that were transmitted via the air or through direct contact can multiply if they are not re-sealed in a sterile manner. This can lead to contamination / infections of the patient's access, since germs can have settled on the closure cap, which can get into the bloodstream, the abdomen, the gastrointestinal tract, or into the patient's body tissue.
- the medical connector is therefore particularly suitable for hemo- and peritoneal dialysis as well as for continuous outpatient peritoneal dialysis (CAPD).
- peritoneal dialysis With peritoneal dialysis (PD) in particular, the continuous guarantee of sterility during the connection / disconnection of a patient access is essential, because within the scope of peritoneal dialysis, a patient is connected up to four times a day from sterile solution bags manually or via a corresponding treatment machine for several years / disconnected from this.
- caps soaked with iodide are usually used in the context of peritoneal dialysis after the peritoneal dialysis solution has entered, which should ensure the sterility of the cap or patient access as best as possible for the duration of the PD solution in the installation space.
- small amounts of disinfectant can also get into the peritoneum
- a connector can also be used, which automatically closes the patient access when it is disconnected.
- the course of the treatment in particular the intake of fresh dialysis solution and the flow of used / used dialysate, is also controlled via the connector.
- the disadvantage of this solution is that a complicated mechanical structure is required for this, which is relatively large and unwieldy and also cost-intensive.
- the present invention is therefore based on the object of alleviating or even eliminating the disadvantages known from the prior art. Specifically, it is an object of the present invention to create a simple medical connector which reduces the risk of germs entering a patient's entrance.
- a connector according to the invention with a first connector part and a second connector part. Furthermore, the present invention relates to a method for the germ-reduced connection / disconnection of a medical connector.
- a medical connector has a first connector part, with an elongated base body with a lumen for conducting a fluid, a first threaded section arranged on an outside of the base body, which enables the first connector part to be releasably connected to a correspondingly adapted second connector part, and a second threaded section arranged on the inner side of the base body on the lumen side, which enables a detachable connection of the first connector part with a correspondingly adapted sealing pin.
- the thread pitch of the first thread section differs from the thread pitch of the second thread section.
- the thread pitch of the second thread section is preferably greater than that of the first thread pitch. But it can also have a multiple of the thread pitch of the first thread section.
- the second thread section is preferably larger than the first ..
- a blocking element or sealing pin is arranged in the lumen of the first connector part, which has a lumen so that fluid can flow through the sealing pin and the lumen of the elongated base body of the first connector part. It is also conceivable and encompassed by the invention that the sealing pin is alternatively or additionally flowed around by fluid. A flow through and / or a flow around is therefore conceivable.
- the sealing pin can assume an open position in which a liquid can flow through the lumen of the connector and the sealing pin and can thus be supplied to a patient.
- the sealing pin can also assume a blocking position / closed position in which the sealing pin blocks a fluid flow through the connector and thus, for example, seals a patient access in a fluid-tight manner and thus seals against germs and the ingress of optional disinfectants.
- the sealing pin preferably has a threaded section on its outside which is designed to threadingly engage with the second threaded section of the first connector.
- the sealing pin does not have a lumen and the fluid can flow past the sealing pin.
- the sealing pin preferably has a limiting element, preferably in the form of a locking toothing, which limits a rotation of the sealing pin relative to the first connector part and / or relative to the connector / a second connector part to one direction.
- the sealing pin preferably has a fixing element at an end opposite the limiting means, by means of which the sealing pin is detachable or non-detachable on a locking element, preferably via a latching connection and / or undercut can be fixed.
- the sealing pin can be held on a closure cap of a patient access by means of the fixing element.
- a connector according to the invention preferably has a second connector part, with an elongated base body with a lumen for conveying a fluid and a receiving section, preferably concentrically surrounding the lumen, for receiving a first threaded section arranged on the outside of the base body of a first connector part.
- the receiving section of the second connector part has a threaded section which is designed to come into thread engagement with the first threaded section of the first connector part.
- a limiting element preferably in the form of a locking toothing, is preferably provided on an inner side of the lumen of the second connector part on the lu side, which is designed to interact with a corresponding limiting element of a sealing pin in order to limit rotation of the sealing pin in one direction.
- the delimiting element is preferably designed as a plurality of ribs extending axially along the elongated base body, along which a sealing pin received in the second connector part is preferably axially displaceable.
- a sealing pin which has a lumen, is preferably arranged in the lumen of the second connector part, so that fluid can flow through the sealing pin and the lumen of the elongated base body of the second connector part, for example to the patient.
- a connector according to the invention preferably has a first connector part and a second connector part, the first connector part preferably being releasably connected to the second connector part by means of thread engagement. Furthermore, it has proven to be advantageous if a sealing pin is arranged in a common lumen formed by the lumens of the first and second connector parts.
- the sealing pin is here preferably movable / movable by a relative movement of the first connector part to the second connector part between an open position in which the sealing pin enables fluid flow through the common lumen and a closed position in which the sealing pin blocks the fluid flow through the common lumen struck.
- the flow rate or amount of flow can be regulated or adjusted by moving the sealing pin.
- Another aspect of the invention relates to a method for fluidically connecting and / or disconnecting a medical connector with the following steps:
- the first connector part here has a sealing pin which is arranged in the lumen of the first connector part so that a common lumen for conducting fluid is formed by the first connector part, the second connector part and the lumen of the sealing pin.
- the first connector part can be arranged on a supply line and the second connector part can be arranged at a patient access. Liquid can thus be supplied to the patient from the supply line.
- the first connector part is released from the second connector part by a relative movement, e.g. rotational movement, of the first connector part relative to the second connector part, as a result of which the sealing pin is moved into a closed position and in the second connector part remains when the first connector part is detached from the second connector part.
- a relative movement e.g. rotational movement
- the pin is pushed into the closed position.
- the sealing pin remains in the lumen of the second connector part.
- the lumen of the second connector part is thus shielded against germs and / or disinfectants penetrating from the outside.
- a closure element in particular in the form of a closure cap, can then be releasably connected to the second connector part.
- a closure cap is screwed onto the patient access.
- the sealing pin is pressed in the axial direction into the lumen of the second connector part, whereby the lumen of the second connector part is sealed to the outside in a fluid-tight manner.
- the locking cap also prevents the pen from moving out of its locking position, e.g. due to vibrations.
- This step is optional.
- the case is also conceivable and encompassed by the invention in which the forward movement of the pin ends with the rotary movement and moves to “stop”. Then the cap is simply snapped into place. The further forward movement of the pin into the patient / machine connector is a safety feature to lock the pin more deeply.
- the sealing pin When connecting the closure element to the second connector part, the sealing pin is preferably fixed on the closure element by means of the fixing element of the sealing pin.
- This embodiment has the advantage that when the closure element is subsequently removed to reconnect the second connector part (eg patient connection), the sealing pin is removed at the same time as the closure element, whereby the lumen of the second connector part is opened fluidically.
- the sealing pin is preferably fixed to the closure element via a latching connection and / or a flint cut on a corresponding receptacle of the closure element. The sealing pin is thus preferably held on the closure element by means of a form fit.
- the closure element is then preferably released from the second connector part, with the sealing pin connected to it also being released from the second connector part at the same time as the release of the closure element, whereby the lumen of the second connector part is fluidically opened and can be reconnected to a supply line.
- the connector according to the invention ensures that a new sealing pin is provided for each treatment, whereby the risk of contamination can be significantly reduced.

- Figures 4a, b, c a sealing pin; 5: a sectional view of the second connector part;
- Fig. 1 shows a connector according to the invention with a first connector part 1 and a second connector part 2, which are releasably connected / screwed to each other.
- the connector according to the invention further comprises a sealing pin 3, which is arranged in a common lumen of the first and second connector parts 1, 2.
- FIG. 2 shows a closure element in the form of a closure cap 4, which instead of the first connector part can be screwed onto the second connector part.
- the spaces between the sealing pin 3 and the first and second connector parts 1, 2 are sealed in a fluid-tight manner by means of sealing elements, for example in the form of O-rings 5.
- the first connector part has an elongated base body 6 with a lumen 7 for conducting a fluid.
- a first threaded section 8 is arranged, which enables a releasable connection of the first connector part 1 with a correspondingly adapted second connector part 2.
- An inside of the base body 6 is on the lumen side a second threaded section 9 is arranged, which enables the first connector part 1 to be releasably connected to a correspondingly adapted sealing pin 3 which has a corresponding threaded section 10.

- FIG. 6 shows a connector according to the invention in the connected state, i.e. during the supply of liquid through the connector. Fluid flows through the connector, as shown in Fig. 6 by the arrow.
- the sealing section
- the first connector part 1 is rotated in the direction of the arrow and thereby unscrewed from the second connector part 2. Due to the thread engagement between the sealing pin 3 and the first connector part 1, the sealing pin 3 also rotates until its rotation is limited / stopped by engaging the locking teeth 11 in the recesses / ribs 18 of the second connector part. At the same time, the sealing pin 3, in particular its sealing section 12), is pressed into the lumen 15 of the second connector part 2, so that the lumen 15 is sealed in a fluid-tight manner by means of the O-ring 5. The first connector part 1 is then released from the second connector part 2, the sealing pin remaining in / on the second connector part 2.
- the outer wall of the 2nd connector protrudes from the outer wall of the second connector after the two connector parts have been loosened and thus represents protection against contact.
- a closure cap 4 which preferably contains a disinfectant, can be placed / screwed onto the first connector part 1 after the disconnection.
- the closure cap has a corresponding threaded section 19 for this purpose.
- the closure cap 4 has in this embodiment Approximately form a receptacle with a circumferential locking lug 20, in which the locking mushroom 13 of the sealing pin is received when the closure cap 4 is applied to the second connector part 2 in the axial direction. In this posi on, the sealing pin is anchored on the closure cap 4.
