Description

Blood component collecting and separating system

Technical Field

The utility model relates to a collection piece-rate system specifically is a blood component collection piece-rate system.

Background

The statements in this section merely provide background information related to the present disclosure and may constitute prior art. In implementing the present invention, the inventors found that there are at least the following problems in the prior art.

Mechanized blood component collection plays an important role in reducing labor intensity, improving labor efficiency and reducing blood pollution. At present, the mechanized blood component collection technology is adopted in China comprehensively and is mainly used for collecting blood components such as plasma and platelets. For example, plasma collection techniques, which basically separate blood plasma from blood cells by centrifugal separation techniques, collect the plasma, and transfuse the blood cells. Because the collected blood needs to be prevented from being coagulated, after the blood is collected from a human body, anticoagulant needs to be input from the anticoagulant interface to perform anticoagulation on the blood, and the anticoagulation enters the separation device through a pipeline to be separated; during or after the collection of blood components, some blood donors need to input physiological saline to supplement body fluid, and at the moment, the physiological saline needs to be connected from the other end of the blood component collection device to input the human body to supplement the body fluid. Because the samples of the infusion bags are similar, although colors are distinguished, the anticoagulant is overproof and is input into a human body to cause injury to the human body and safety accidents are caused by the fact that puncture and infusion are wrong frequently caused by busy work and carelessness in clinic; or the collected blood may be coagulated due to lack of anticoagulant, resulting in loss.

Aiming at the problems, an alarm mode is mainly adopted at present to remind an operator of connection errors. For example, the patent with the application number of CN201620028708.2 entitled "a liquid bag detection and differentiation device for an apheresis machine" uses a size or weight sensor to test the size or weight of an infusion bag and compares the size or weight with a preset size or weight. And when the operation is not in accordance with the preset operation, an alarm is given through an alarm, so that the wrong operation is corrected. However, since the blood component collecting and separating system is mainly used for blood sampling operation in hospitals or blood sampling vehicles, the outside is very noisy, and in addition, a plurality of operations such as starting up, sterilizing, connecting infusion bags and the like are required, operators cannot easily notice the alarm of the alarm, and the continuous operation is easy to cause medical accidents.

The liquid medicine infusion set comprises an interface connected with the liquid medicine bag and a joint connected with the infusion tube. The traditional interface usually adopts a rubber-sealed joint of a diaphragm two-way or a combined cover, which is used as a blocking piece to seal the liquid medicine from flowing out. The joint adopts a needle head, and the needle head is punctured into the rubber joint, so that the liquid medicine bag or the liquid medicine bottle is communicated with the infusion tube, and the liquid medicine flows out. The infusion mode has the risk of stabbing medical care personnel due to the use of the needle, and particularly for patients with infectious diseases, the risk of infection of the medical care personnel is greatly increased. Rubber joint has the piece to drop into infusion passageway easily when the syringe needle puncture, causes the infection to the patient, and rubber joint leakproofness is relatively poor, and the syringe needle punctures many times and can make the rubber pad leakproofness not enough and cause patient's infection. There is also a risk that the needle is easily torn off, since it penetrates the rubber joint. Also, to prevent bacterial infection, both the rubber nipple and the needle are typically sterilized during penetration.

Currently, a needleless drug infusion set, such as the one named needleless infusion connector of application No. 201320379673.3, uses an i-shaped silicone valve as a blocking member disposed in an interface (i.e., in a housing of an infusion base) to close a drug outlet of an infusion bag and prevent the drug from flowing out. The infusion apparatus with the hollow joint is inserted between the I-shaped silica gel valves, so that the infusion apparatus is communicated with the infusion bag, and the liquid medicine flows out. However, since the I-shaped silica gel valve is in a state of being communicated with the outside, the risk of bacteria being brought in is inevitable when the infusion set with the connector is inserted, and therefore, the interface (namely the blocking piece) and the connector still need to be disinfected when the infusion set is inserted. In addition, because the sealing ring and the pressing area are adopted to press and fix the joint, the joint is separated from the interface due to large force. The insertion of the joint into the silica gel valve is not very suitable for practical operation, if the extrusion area of the silica gel valve is too tight, an operator needs to take great effort to insert the joint, and the joint needs to be aligned with the middle of an I-shaped body to be inserted, otherwise the joint is easy to deviate, and the operation is very inconvenient in practical clinic; if the silica gel valve extrusion region is loose, easily cause the poor problem of leakproofness again, lead to the liquid medicine to flow out, or the bacterium gets into the liquid medicine bag.

Detailed Description

The following description of the present invention will be further described with reference to the accompanying drawings, and the embodiments of the present invention are only used for illustrating the present invention and not for limiting the present invention, and various replacements and modifications can be made according to the common technical knowledge and the conventional means in the field without departing from the technical idea of the present invention, and all should be included in the scope of the present invention.

As shown in fig. 4, a blood component collection and separation system includes a venipuncture instrument 11, a separation device 12, a collection device 13, a first infusion device 9 and a second infusion device 10; the first infusion device 9 is connected between the venipuncture instrument 11 and the separation device 12 through a medical fluid infusion device 5 and a multi-way piece; the first interface of the first infusion set 9 is uniquely adapted to the first connector; the second interface of the second infusion set 10 is uniquely adapted to the second connector.

The first infusion set 9 comprises a first reservoir 7 with a first interface and a first connector adapted to the first interface. The second infusion set 10 comprises a second reservoir 8 with a second interface and a second connector adapted to the second interface. The connector 6 and the interface 2 of the first infusion device 9 and the second infusion device 10 are connected in a unique adaptive mode, and the first infusion device and the second infusion device can be not connected due to incompatibility when in wrong connection, so that misoperation of taking wrong infusion bags by operators is prevented, and medical accidents caused by wrong liquid medicine infusion are avoided from a physical layer.

Optionally, the first interface adopts a diaphragm two-way or a combined cover, the first joint adopts a puncture outfit, the second interface is the interface 2 with a stopper 3, and the second joint is the joint 6 matched with the interface 2, as shown in fig. 4; or, the first interface is the interface 2 with the blocking piece 3, the first joint is the joint 6 matched with the interface 2, the second interface adopts a diaphragm two-way or a combined cover, and the second joint adopts a puncture outfit.

Because the interface 2 with the blocking piece 3 can only be matched with the matched joint 6 uniquely, when the interface 2 is connected with a puncture outfit or the joint 6 is connected with a diaphragm two-way or a combined cover, the connection can not be realized due to the mismatching of the connection, and the medical accident of wrong liquid medicine infusion is avoided from the physical layer.

The first storage container 7 is an anticoagulant bag, and the liquid outlet is connected with a first interface which adopts a diaphragm two-way or a combined cover. The second storage vessel 8 is a liquid refill bag and the liquid outlet is connected to the interface 2 using a stopper 3, as shown in fig. 4. If operation errors occur, when an operator mistakenly takes the anticoagulant bag as a liquid supplement bag, the puncture outfit cannot penetrate through the interface 2 with the stopper 3 on the liquid supplement bag, and connection errors occur; when an operator takes the liquid supplementing bag into the anticoagulant bag by mistake, the joint 6 cannot be connected with the two-way diaphragm or the combined cover, the connection is also wrong, the connection cannot be realized due to the incapability of adapting, and the medical accident of wrong liquid medicine infusion is avoided from the physical layer. And will not be influenced by external interference factors.

Other liquid medicine infusion sets which cannot be matched with the interface 2 or the connector 6 can be adopted to achieve the same effect as the septum two-way or the combined cover.

Then, by connecting the joint 6 with the interface 2, the joint 6 is communicated with the interface 2, and the blocking member 3 is placed in the open state, so that the liquid medicine in the liquid medicine storage container 1 can flow into the liquid medicine infusion device 5 through the interface 2 and the joint 6, thereby realizing infusion. The liquid medicine infusion device 5 is an infusion tube or a connecting tube. The liquid medicine storage container 1 is a soft bag such as an infusion bag, so that an operator can operate the blocking member 3 from the outside of the liquid medicine storage container 1 and control the opening of the blocking member 3.

By adopting the mode, a needle head is not needed, and the risk that medical staff are stabbed by the needle head is avoided. And the blocking piece 3 is positioned at the liquid outlet of the liquid medicine storage container 1 and separates the interface 2 from the outside, thereby greatly reducing the risk of bacteria invasion.

Optionally, the second end of the interface 2 is a conical joint, and the first end of the joint 6 is a conical joint adapted to the second end of the interface 2. For example, the second end of the interface 2 is an external conical joint, as shown in fig. 2; the first end of the adapter 6 is an internal conical adapter adapted to the mouthpiece 2, as shown in fig. 3. The conical joint is a non-rigid joint, for example, the conical joint is made of plastic material, and the interface 2 and the joint 6 are fixedly connected together by inserting the inner conical joint of the joint 6 into the outer conical joint of the interface 2 to make interference fit, as shown in fig. 1. By opening the stopper 3, the drug solution storage container 1 is communicated with the drug solution infusion device 5 through the mouthpiece 2 and the joint 6, and the drug solution can smoothly flow down. Vice versa, the second end of the port 2 is an internal conical joint and the first end of the joint 6 is an external conical joint, the internal conical joint of the port 2 being inserted into the external conical joint, so that the port 2 and the joint 6 are fixedly connected.

For example, the closed end of the protective cap 4 is sealed, the open end is provided with internal threads, the protective cap is matched with the external threads on the periphery of the interface 2 or the joint 6, and the interface 2 or the joint 6 is sealed in a threaded connection mode, as shown in fig. 2 or 3, so that the interface 2 and the joint 6 are prevented from being invaded by bacteria due to being arranged in the outside, and the communication and the pollution caused after the liquid medicine flows down are avoided, and the health of a patient is endangered. When the liquid medicine infusion external member is required to be connected, the connection operation of the interface 2 and the joint 6 can be carried out only by detaching the protective cap 4, and an operator does not need to disinfect the interface 2 and the joint 6 any more, so that the operation is simpler and more convenient.

The open end of the protective cap 4 can be detachably connected with the interface 2 and the joint 6 by covering or twisting.

When the transfusion operation, particularly the operation of changing the liquid medicine bag, is carried out, the liquid medicine bag is firstly hung at a relative high position, or the liquid medicine bag is hung at the high position in advance; then the connector 6 is butted with the interface 2, and finally the channel is opened to allow the liquid medicine to flow down. If the switch for opening the access is too high or the operation is complicated, the burden and the operation difficulty of the operator can be greatly increased. The utility model provides a stopper piece 3 is located the liquid outlet, and only needs to break stopper piece 3 or upwards lift up can open the route, convenient and fast more.
