Abstract
The utility model provides a blood bag disposable sampler which comprises a sampler main body, wherein the sampler main body is a columnar staircase structure; the sampler main body comprises a guide tube and a sampling part; the sampling part is a truncated cone structure of which the inside is provided with a hollow circular groove; a sampling needle is connected to the inside of the guide tube; the tail of the sampling needle penetrates out of the closed end of the guide tube; and the head slightly protrudes out of the other end of the guide tube and is connected to the inside of the hollow circular groove in the sampling part. The sampling part directly penetrates into the blood taking tube on the blood bag; the blood is guided into the vacuum blood taking tube connected with the closed end of the guide tube through the sampling needle; and after the blood delivery is finished, the disposable sampler and the blood taking tube of the blood bag are discarded, and the blood sample in the vacuum blood taking tube is made into a sampling specimen. The blood bag disposable sampler avoids the possible risk of sample pollution when the scissors shears the blood bag sampling tube in the sampling process.
Description
Technical field
The utility model relates to medical instruments field, is specifically related to a kind of for gathering the disposable sampling thief of blood bag of blood.
Background technology
Bacterial contamination, virus infections and the blood group mistake of blood are three big factors of transfusion safety.Domestic and international many bibliographical informations even if use band sampling apparatus plastic blood bag, may be cut the heparin tube situation on multiple blood bags with a scissors in practical process, and cross-infection risk is very high, may cause sample contaminated.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of blood bag disposable sampling thief, its objective is and prevents the pollution to blood in blood collection procedure.
For achieving the above object, the technical solution of the utility model is as follows:
The disposable sampling thief of a kind of blood bag, it comprises sampling thief main body, described sampling thief main body is column step structure, described sampling thief main body comprises ingress pipe and sampling portion, described sampling portion is that frustum cone structure and inside offer hollow circular groove, in described ingress pipe, be connected to sampling needle, the afterbody of sampling needle is piercing in sealing one end of ingress pipe, and head slightly protrudes from the ingress pipe other end and accesses in the hollow circular groove of sampling portion.
Preferably, the end of sealing one end of described ingress pipe offers circular trough, and the afterbody of described sampling needle is placed in this circular trough.
Pass through technique scheme, the disposable sampling thief of a kind of blood bag that the utility model provides, its beneficial effect is: sampling portion directly thrusts in the heparin tube on blood bag, blood is directed in by sampling needle in the conduit of ingress pipe blind end connection, after blood transport, residual blood will be stranded in the hollow circular groove of sampling portion, so only blood residual in sampling portion open circles need to be extracted and may be made in sampling sample.That the utility model has been avoided from blood bag direct sample and the risk of the blood contamination that produces.
Brief description of the drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, will the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below.
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
The present embodiment as shown in Figure 1, the disposable sampling thief of a kind of blood bag, it comprises sampling thief main body (1), described sampling thief main body (1) is column step structure, described sampling thief main body (1) comprises ingress pipe (2) and sampling portion (3), circular trough is sealed and offered in one end of described ingress pipe (2), described sampling portion (3) offers hollow circular groove for frustum cone structure and inside, in described ingress pipe (2), be connected to sampling needle (4), the afterbody (5) of sampling needle (4) is piercing in sealing one end of ingress pipe (2) and is placed in circular trough, head (6) slightly protrudes from ingress pipe (2) other end and accesses in the hollow circular groove of sampling portion (3).
The present embodiment has comprised ingress pipe (2) and sampling portion (3) two parts, in wherein in ingress pipe (1), be connected to sampling needle (4), one end that the afterbody (5) of sampling needle (4) is directly piercing in ingress pipe (1) sealing is directly connected with conduit, and the head (6) of sampling needle (4) protrudes from the other end of ingress pipe (1) and is placed in the hollow circular groove of sampling portion (4).Sampling portion (4) is designed to frustum cone structure, and blood bag up-sampling pipe will be clamp-oned in the hollow circular groove in sampling portion (4), and be pierced through blood drainage is guided to conduit through sampling needle (4) by the head (6) of sampling needle (4).In order to increase the connective stability of conduit between ingress pipe (2), offer circular trough in ingress pipe (2) sealing one end, so in conduit access circular trough, make to form extruding force between ingress pipe and conduit and ensure connective stability.
Sampling portion directly thrusts in the heparin tube on blood bag, blood is directed in by sampling needle in the conduit of ingress pipe blind end connection, after blood transport, residual blood will be stranded in the hollow circular groove of sampling portion, so only blood residual in sampling portion open circles need to be extracted and may be made in sampling sample.That the utility model has been avoided from blood bag direct sample and the risk of the blood contamination that produces.
The above-mentioned explanation of embodiment disclosed in the utility model, makes professional and technical personnel in the field can realize or use the utility model.To be apparent for those skilled in the art to the multiple amendment of these embodiment, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
