- An infusion solution in which an infusion tube is attached to an infusion pump for the purpose of delivering a medicinal solution, a nutrient, blood, or the like to a patient or a infusion line at a predetermined speed and timing in a medical field.
- the system is used.
- the peristaltic pump includes a finger type having a plurality of fingers (protrusions) or a roller type having a plurality of cylindrical rollers.
- the infusion tube is disposed so as to contact the finger or the roller.
- the finger is deformed by being pressed and crushed so as to handle the side surface of the infusion tube by the finger movement or the roller rotation.
- a peristaltic movement is made and the chemical solution in the tube is distributed in a certain direction.
- the flow rate of the drug solution in the infusion tube by appropriately setting the peristaltic motion of the finger of the infusion pump or the rotation speed and driving time of the roller, the number of infusion tubes, the diameter of the infusion tube, etc.
- the drug solution is administered to the patient and the delivery line.
- Patent Documents 1 and 2 are equipped with a safety mechanism for preventing the occurrence of free flow as one mechanism of the infusion pump.

When the cover is opened during driving due to operational error, etc., the safety clamp is automatically activated to close the infusion tube and stop the infusion. Yes.
- Patent Document 1 JP 2004-57577 A
- Patent Document 2 JP 2000-300667 A
- the operating conditions of the safety mechanism of the infusion pump shown in Patent Documents 1 and 2 are based on the premise that the infusion tube is set in the infusion pump. No safety measures are envisaged in situations where the tube is completely detached. For this reason, for example, when a considerable pulling force is applied to the infusion tube due to an erroneous operation or unexpected reason of a nurse, and the infusion pump force is completely detached, the mechanism such as the safety clamp no longer works. Does not work.
- the conventional safety mechanism is provided so as to be almost integrated with the infusion pump due to its structure. Therefore, in order to obtain the effect, an infusion pump having the mechanism must be purchased. For an infusion pump that has already been used in the medical field or has no safety mechanism, the safety mechanism has to be purchased. Cannot be newly granted. Based on the above, there is still room for improvement in safety mechanisms such as free flow in infusion systems.
- the present invention has been made in view of the above problems.
- the infusion pump force in the case where the infusion tube is detached with a relatively simple and low-cost configuration, free flow is achieved.
- An infusion safety device capable of effectively solving such infusion problems as above is provided.
- a second object is to provide a safety device that can be newly added to an existing infusion pump that does not have a safety device.
- the present invention includes a clamp that is attached to an infusion tube and a socket that detachably accommodates the clamp, and the clamp is provided in the infusion tube in a state of being accommodated in the socket.
- the clamp can be detached from the socket, and in the detached state, the infusion tube is pressed.
- the clamp may have a insertion path through which the infusion tube is inserted, and may include a movable mechanism that limits the flow of the infusion by changing the diameter of the insertion path.
- the clamp includes a housing having a hollow portion that communicates with the first through hole and the first insertion port, a movable body that is slidably housed in the hollow portion, and has a second through hole, And an urging means for slidably urging the movable body in the hollow portion, and the movable mechanism is configured to slide the movable body in the hollow portion by the urging means, thereby
- the insertion path may be overlapped in each opening direction to form the insertion path, and the degree of the overlap may be changed to change the diameter of the insertion path.
- the clamp at least one pair of the first through-holes is provided on a side surface of a casing made of a bottomed cylindrical body, and the second through-holes are provided in the hollow portion of the casing.
- the movable body having the structure is housed together with the urging means, and the length of the clamp in the longitudinal direction changes and the diameter of the insertion path changes as the movable body slides in the longitudinal direction of the casing.
- the socket includes a pair of locking walls disposed at a shorter interval than the clamp length in the detached state, and the clamp is configured such that the movable body is pressed toward the housing against the biasing means, and One of the sockets can be accommodated between the pair of locking walls with the insertion opening opened.
- a panel body can be used as the biasing means.
- the clamp may be formed with a slit for placing an infusion tube in the insertion path from the side of the housing.
- the clamp can be housed in the socket with the slit facing the socket.
- the clamp may be configured to be detached from the socket along the longitudinal direction of the infusion tube.
- the present invention provides an infusion pump set in which the infusion safety device is attached to an infusion pump.
- the socket can be mounted on the infusion pump side with a strength greater than the pulling force related to the detachment of the clamp.
- the infusion safety device of the present invention having the above-described configuration is a system in which the clamp and the socket are detached from each other, and is configured to limit the infusion volume of the infusion tube when the clamp is detached from the socket. Yes.
- an infusion tube is attached to a clamp and this is accommodated in the socket.
- the infusion tube is attached to the pump side for normal driving. If the infusion tube is removed from the infusion pump side, an external force is applied to the clamp together with the infusion tube, and these are detached from the socket. This separation activates the clamp and presses the infusion tube, thereby effectively suppressing problems such as free flow.
- the conventional safety device as a countermeasure against free flow mentioned in Patent Documents 1 and 2 and the like is integrally incorporated in the pump as a configuration of the infusion pump. When it is completely separated, the safety mechanism can no longer operate, but if the infusion safety device of the present invention is used in combination with an infusion pump, such a problem can be fundamentally solved.
- the infusion safety device of the present invention additionally attaches the socket to an existing one later by using various fixing tools such as adhesive tape, adhesive, and screws at a predetermined position of the infusion pump. It is also possible to have a very versatile feature. For this reason, it is very cost-effective because it is not necessary to buy a new infusion pump to obtain a safety device. In addition, the configuration is relatively simple and has high feasibility.
