Example 1

As shown in FIG. 1, the present embodiment provides a medical diagnostic blood delivery tube, and in particular, an arterial blood storage blood delivery tube. The blood delivery tube comprises a tube body 1, an elastic negative pressure part 2 and a cover body 3. The cover 3 has a sealing interface to enable the tube 1 to be sealingly connected to the cover 3. The lid body 3 is provided with a receiving hole capable of receiving the blood suction tube 4. Preferably, the elastic negative pressure portion 2 includes an elastic bladder cavity 2a and a lumen cavity 2 c. One end of the lumen 2c is connected to the elastic bladder 2a so that the elastic negative pressure portion 2 can discharge air inside the chamber through the lumen 2c in a manner of squeezing the elastic bladder 2a to form a collapsed configuration. The other end of the cavity tube 2c extends to the inside of the tube body 1 in a sealing connection mode through a through hole arranged on the tube body 1, so that the elastic negative pressure part 2 can be in sealing communication with the tube body 1 through the cavity tube 2 c. Thus, during the arterial blood drawing process, the injected blood will gradually make the elastic negative pressure part 2 form an expansion structure by discharging the gas in the tube body 1 into the compression structure, thereby effectively playing a role of protection.

Preferably, the material of the elastic capsule 2a is PVC or PE.

Preferably, the elastic negative pressure portion 2 further comprises a bore 2b and a tap 2 d. The cavity hole 2b is provided in the elastic bag cavity 2 a. The diameter of the cavity hole 2b is larger than that of the lumen 2c, so that the elastic bladder 2a can be formed into a collapsed configuration by squeezing the elastic bladder 2a to discharge air inside the cavity from the cavity hole 2b under the condition that the elastic negative pressure portion 2 is in sealed communication with the tube body 1. In the blood sampling process, the cock 2d is in a state of being engaged with the cavity hole 2 b. This configuration enables the negative pressure space to be formed efficiently, and also enables the pressing force to be reduced.

Preferably, the through-hole is configured as an internal thread. The lumen 2c can extend to one end of the tube 1 and is configured with an external thread which is engaged with the internal thread. So that the elastic negative pressure part 2 can be in sealed communication with the tube body 1 through the cavity tube 2c under the condition that the internal thread is matched with the external thread.

Preferably, the elastic bladder cavity 2a is able to develop an inflated configuration from a deflated configuration, based on the gas expelled by the tube body 1 during the blood infusion process, with the tap 2d engaged with the cavity 2 b. The formed expansion structure can effectively play a role of buffering when the expansion structure collides with other objects, and can effectively prevent the expansion structure from being broken. The flexible bladder 2a of the present invention is capable of directing blood flow during deflation, on the one hand. On the other hand, the expansion structure formed in the process of blood pressure flowing into the tube body 1 can play a role in protection.

Preferably, the diameter of the cap 3 is larger than the diameter of the tube 1. The cover 3 is provided with a plurality of concave portions and convex portions. The concave portions and the convex portions are arranged at intervals around the axis of the lid body 3. The arrangement can effectively prevent the blood conveying pipe from rolling and falling from a high place.

Preferably, the elastic bladder lumen 2a is integrally connected with the lumen tube 2 c.

Preferably, the tap 2d is an interference fit with the bore 2 b.

Preferably, the end of the blood-sucking vessel 4 is a pointed structure. The pointed mechanism can pierce the soft glue on the accommodating hole. Thus, the blood suction tube 4 can be extended to the inside of the tube body 1 by piercing the soft gel on the receiving hole based on the tip portion provided at the end portion thereof.

Preferably, the pipe body 1 is provided with scale marks. The scale lines facilitate the observation of blood volume.

Preferably, the bottom of the pipe body 1 is provided with a rubber protection layer. The rubber protective layer can reduce the buffer effect when the blood conveying pipe falls, and can effectively prevent the blood conveying pipe from being broken.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims. The scope of the invention is defined by the claims and their equivalents.
