Description

Anti-coagulation blood collection bag

Technical Field

The utility model mainly relates to the medical field, in particular to an anti-coagulation blood collection bag.

Background

The blood collection bag can be used for collecting, processing, storing, transferring blood and blood components and the like, and is widely applied to medical and biological medicine experiments. The blood collection bag currently used consists of a blood collection needle, a blood collection tube and a blood storage bag, and collected venous blood flows into the blood storage bag through the blood collection needle and the blood collection tube.

Before use, a sufficient amount of anticoagulant (e.g., pre-collection of a quantity of blood, a 4:1 ratio is required to pre-fill the anticoagulation solution) needs to be placed in the blood storage bag in advance, and after blood withdrawal, continuous weighing and mixing is performed by a manual or shakable scale. Once in the blood sampling process, the blood sampling is interrupted due to the body of a patient or external factors, the proportion of the anti-coagulation liquid is not correct, and the anticoagulation effect (blood effect) is affected. Meanwhile, the pure shaking is difficult to completely mix the blood and the anticoagulation liquid.

Detailed Description

The present utility model will be further described with reference to the following examples in order to better understand the technical solutions of the present utility model and to make the above features, objects and advantages of the present utility model more clearly understood. The examples are only for illustrating the present utility model and are not intended to limit the scope of the present utility model.

As shown in fig. 1-3, the present utility model includes: through the sampling needle, sampling bag and blood sampling bag 1 that advance blood pipe intercommunication, blood sampling bag 1 is close to advancing blood vessel department, is connected with anticoagulation bag 2, anticoagulation bag 2 embeds anti-congeal liquid, can dismantle with blood sampling bag 1 through sealed pipe structure and be connected, and the outside of blood sampling bag 1 still is equipped with external hanging structure 3 and blood volume scale mark 4.

When the blood sampling device is used, the anticoagulation liquid does not need to be injected into the blood sampling bag 1 in advance, but is synchronously injected through the anticoagulation bag 2 and the blood sampling bag 1 before the sampling needle is connected into the vein of a sampling person, so that the injected blood and the anticoagulation liquid are mixed in an equal ratio. Once the patient needs to terminate in time due to himself or an external factor, the infusion of the anticoagulant fluid can be reduced by breaking the anticoagulant bag 2, and the mixing of the equal ratios in the bag can be completed.

As a complete use of the anti-coagulation pouch 2:

the anticoagulation bag 2 comprises a connecting pipe 21 and an elastic medicine bag 22, the medicine liquid is arranged in the elastic medicine bag 22, one side of the connecting pipe 21 is communicated with the elastic medicine bag 22, and the other side is of a tubular structure and is sealed through a sealing film. So that the anticoagulant capsule 2 is normally in a sealed state with an internal pressure greater than an external pressure.

The sealed catheter structure comprises a tubular structure at one side of the connecting pipe 21, a connecting port at the surface side of the blood collection bag 1 and a cross needle in the blood collection bag 1, wherein the cross needle corresponds to the sealing film in size. After the connecting tube 21 of the anticoagulation bag 2 is connected to the connecting port on the front side of the blood collection bag 1, the connecting tube is pressed down with force, so that the cross needle pierces the sealing membrane, and the anticoagulation bag 2 enters the blood collection bag.

In order to obtain the optimal anticoagulation effect, the volume ratio of the liquid medicine in the anticoagulation bag 2 to the blood collection amount in the blood collection bag 1 is 1:4. The ratio of the flow rates is not more than 1-4. (controllable by the pipe diameter of the connecting pipe 21).

The junction of tubular structure and connector is sealed through the sealing washer, and the connector outside still is connected with sealed end cap to prevent that anticoagulation liquid from revealing.

In order to facilitate the practical operation, it is also necessary to provide an external hanging structure 3 so that the whole blood collection bag 1 is in a vertical state. The hanging structure 3 may be a hanging hole. Alternatively, the add-on structure 3 may be a retaining clip. To achieve the purpose of vertical fixation, in order to determine how much solution (blood) is built in. The blood volume graduation marks 4 are longitudinally arranged. Here, the blood volume graduations 4 are not equally spaced due to the narrow upper and wide lower portions of the blood collection bag 1 after the blood collection bag is refilled with blood.

The above-described embodiments are merely illustrative of the principles of the present application and their effectiveness, and are not intended to limit the present application. Modifications and variations may be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present application. Accordingly, it is intended that all equivalent modifications and variations which a person having ordinary skill in the art would accomplish without departing from the spirit and technical spirit disclosed in the present patent application shall be covered by the claims of the present patent application.
