Description

A suction head for autologous blood recovery

technical field

The utility model relates to a medical device, in particular to a suction head for recycling autologous blood, which is suitable for autologous blood recycling during surgical operations.

Background technique

At present, the disposable blood recovery pipeline widely used clinically is a double-lumen tube, which is composed of two parts, and the thin tube part is adhered to the thick tube. The thin tube is a medicine dropping tube, its beginning end is connected with the anticoagulant medicine bag, and its end is an anticoagulant outlet. The thick tube is a blood supply, the end of which is connected with the blood reservoir, and the beginning and end of the thin tube have a common opening, which is connected with the suction head. During negative pressure suction, the surgical field blood must pass through the suction head, then enter the opening of the double-lumen tube, and then mix with the anticoagulant and enter the blood supply. The disadvantage of this design is that the surgical field blood cannot be mixed with the anticoagulant immediately, and it is easy to coagulate and produce blood clots in the suction head; in addition, it is easy to mix air with the surgical field blood during negative pressure suction. The red blood cells produce direct physical damage, leading to red blood cell deformation and even hemolysis, thereby reducing the efficiency of red blood cell recovery.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a device with simple structure, which can reduce the mixed suction of air, can avoid blood coagulation in the suction head, effectively reduce the physical damage of air to red blood cells, and effectively protect red blood cells. A suction head for autologous blood salvage.

A suction head for autologous blood recovery, comprising a suction head and a medicine drop tube, at least one medicine drop tube is connected to the outer wall of the suction head, and the outlet of the medicine drop tube is connected to the mouth of the suction head. The suction port is on the same plane.

A plurality of the medicine dropping tubes are evenly arranged on the outer wall of the suction head, and the ends of the multiple medicine dropping tubes converge and are connected with the anticoagulant medicine bag.

Due to the adoption of the above structure, the utility model has the following advantages: one or more medicine droppers are designed on the traditional suction head, so that the medicine dropper and the liquid suction port of the suction head are on the same plane. During negative pressure suction, the anticoagulant flows out from the dropper, and is quickly inhaled by the suction head together with the surgical wild blood, and enters the blood supply after mixing. In this way, it is convenient for the anticoagulant to mix with the surgical field blood immediately after being aspirated, which can prevent the surgical field blood from coagulating in the suction tube. In addition, the anticoagulant forms a liquid surface at the opening of the suction head, which can effectively reduce or even avoid the inhalation of air, reduce the damage of air to red blood cells, and improve the efficiency of red blood cell recovery

In summary, this device realizes the instant mixing of surgical blood and anticoagulant, and reduces the mixed inhalation of air, which can prevent surgical blood from coagulating in the suction head, effectively reduce the physical damage of air to red blood cells, and finally effectively Protects red blood cells and improves red blood cell recovery.

Detailed ways

Below in conjunction with accompanying drawing, the specific implementation manner of this patent is described in further detail.

As shown in Figures 1 to 2, the suction head 1 is attached with one or more droppers 2, the droppers 2 and the suction head 1 are integrally formed, and the outlet of the dropper 2 and the suction port of the suction head 1 are in the On the same plane, the ends of one or more medicine dropping tubes 2 are connected to the anticoagulant medicine bag 3 after confluence. The end of the suction head 1 is connected to the supply vessel 4 , and the end of the supply vessel 4 is connected to the blood storage tank 5 . The rate of anticoagulant is adjusted according to the specific clinical situation. After the negative pressure is provided from the outside, the suction head 1 sucks in the surgical field, and at the same time, the anticoagulant flows out from the dropper 2 and is quickly sucked in by the suction head 1 . The surgical field blood and the anticoagulant are mixed and then enter into the supply vessel 4 . Enter the blood storage tank 5 at last.

Fig. 2 is a cross-sectional view of Fig. 1A-A under different structures. As shown in Fig. 2a, the suction head 1 has one medicine drop tube 2; as shown in Fig. 2b, the suction head 1 has four medicine drop tubes 2; As shown in Figure 2c, the suction head 1 has eight droppers 2.

Claims (2)

1. one kind is used for the sucking head that autoblood reclaims, and comprises sucking head and medicinal drop, and it is characterized in that: be connected with at least one described medicinal drop on the outer wall of described sucking head, the outlet of described medicinal drop and the liquid sucting port of described sucking head are in same plane.

2. be used for according to claim 1 the sucking head that autoblood reclaims, it is characterized in that: many described medicinal drops are evenly arranged on the outer wall of described sucking head, and the end of many described medicinal drops converges and is connected with the anticoagulant medicated bag.
