Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a visual exhaust type venous blood sampling device. Background Art

[0002] Venous blood collection needles are usually used in conjunction with vacuum blood collection tubes to collect blood samples during medical examinations. In the actual blood collection process, the blood collection needle of the venous blood collection needle punctures the patient's blood vessels to connect with the blood vessels; the human body's venous pressure is low, so a certain amount of negative pressure is preset in the production process of vacuum blood collection tubes. When the tail needle punctures into the vacuum blood collection tube, the blood automatically flows into the vacuum blood collection tube due to the negative pressure in the vacuum blood collection tube.

[0003] During the actual use of the venous blood collection needle by medical staff, due to the long transparent connecting hose, there is a lot of residual gas in the hose. After connecting to the vacuum blood collection tube, the residual gas in the transparent connecting hose will be sucked into the vacuum blood collection tube, causing insufficient blood in the vacuum blood collection tube and affecting the quality of blood collection.

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present application. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] At present, the connecting hose of the venous blood collection needle commonly used in clinical practice is relatively long, and the human venous pressure is relatively low. When medical staff perform venous blood collection, after successful puncture, there is a lot of residual gas in the hose of the blood collection needle. After the negative pressure venous blood collection tube is connected, the residual gas in the hose will be sucked into the tube, resulting in insufficient blood in the tube, affecting the quality of blood collection.

[0027] Figure 1 A schematic structural diagram of a visual exhaust type venous blood sampling device according to an embodiment of the present application is shown. Figure 2 The structure diagram of the hard transparent plastic tube 3 and the tail needle 4 of the visual exhaust type venous blood sampling device according to the embodiment of the present application is shown. Figure 1 and Figure 2 As shown, the visible exhaust type venous blood sampling device includes a blood collection needle 1, a transparent connecting hose 2, a hard transparent plastic tube 3 and a tail needle 4.

[0028] The blood collection needle 1 is used to pierce a patient's blood vessel and establish a communication relationship with the blood vessel, so that the blood in the blood vessel flows into the blood collection needle 1.

[0029] One end of the transparent connecting hose 2 is connected to the tail end of the blood collection needle 1, so that the blood in the blood collection needle 1 flows into the transparent connecting hose 2; the other end of the transparent connecting hose 2 is connected to one end of the hard transparent plastic tube 3, so that the blood in the transparent connecting hose 2 flows into the hard transparent plastic tube 3.

[0030] An exhaust hole 31 is provided on the side of the end of the hard transparent plastic tube 3 away from the transparent connecting hose 2, and a sealing rubber plug 32 is provided at the exhaust hole 31. The hard transparent plastic tube 3 has a certain hardness, which is convenient for medical staff to operate the sealing rubber plug 32 to timely block the exhaust hole 31; if the hardness is insufficient, the plastic tube wall may collapse or collapse when the sealing rubber plug 32 blocks the exhaust hole 31, resulting in the problem that the sealing rubber plug 32 is not easy to block the exhaust hole 31.

[0031] The tail end of the tail needle 4 is connected to the other end of the hard transparent plastic tube 3 .

[0032] It should be pointed out that the tail ends of the blood collection needle 1 and the tail needle 4 both refer to the end away from the needle tip; according to the direction of blood flow, the needle tip of the blood collection needle 1 is the first end, the tail end of the blood collection needle 1 is the second end, the first end of the tail needle 4 is the tail end, and the second end of the tail needle 4 is the needle tip; the first end of the blood collection needle 1 punctures into the blood vessel, the second end of the blood collection needle 1 is connected to the first end of the transparent connecting hose, the second end of the transparent connecting hose 2 is connected to the first end of the hard transparent plastic tube 3, the second end of the hard transparent plastic tube 3 is connected to the first end of the needle tail, and the second end is used to pierce into a vacuum blood collection tube or a negative pressure blood collection tube.

[0033] According to the above technical solution, the bubbles and bubble movement in the tube can be observed through the transparent connecting hose 2 and the hard transparent plastic tube 3, the bubbles can be discharged through the exhaust holes 31 on the hard transparent plastic tube 3, and the exhaust holes 31 can be sealed in time by the sealing plug 32 to prevent blood from flowing out of the exhaust holes 31.

[0034] In actual use, exhaust is completed first, and then the exhaust hole 31 is blocked, and then the tail 4 is connected to the vacuum blood collection tube (negative pressure venous blood collection tube) by puncture.

[0035] In one embodiment, one side of the sealing rubber plug 32 is connected to the outer tube wall of the hard transparent plastic tube 3 through a soft belt 34 .

[0036] The above technical solution can prevent the sealing plug 32 from being lost.

[0037] In one embodiment, a plug ear 321 is provided on the other side of the sealing rubber plug 32. Exemplarily, the plug ear 321 is a sheet-like structure protruding from the outside of the cylindrical body of the sealing rubber plug 32.

[0038] The above technical solution avoids the difficulty in removing the sealing plug 32 when opening the exhaust hole 31.

[0039] In one embodiment, a lateral boss 33 is provided on the side of the hard transparent plastic tube 3 away from the transparent connecting hose 2, the exhaust hole 31 is arranged in the lateral boss 33, and the sealing plug 32 is sleeved on the end of the lateral boss 33 away from the hard transparent plastic tube 3.

[0040] The above technical solution makes the sealing plug 32 more firmly fixed and can better block the exhaust hole 31, preventing external bacteria, viruses, etc. from entering the tube through the exhaust hole 31 after the exhaust is completed and the sealing plug 32 is installed (when exhausting, the air flow is outward, and bacteria and viruses can enter in the countercurrent).

[0041] In one embodiment, a needle handle 11 is provided on the side of the blood collection needle 1 near the tail end.

[0042] The above technical solution can make the puncture operation of the blood collection needle 1 more convenient.

[0043] In one embodiment, the tail end of the tail needle 4 is fixed to the other end of the hard transparent plastic tube 3 .

[0044] According to the above technical solution, the tail needle 4 can be operated to pierce the vacuum blood collection tube through the hard transparent plastic tube 3, and there is no need to provide a needle handle 11, thus saving materials and costs.

[0045] In one embodiment, a silicone protective film 41 is disposed on the outer sleeve of the tail needle 4 , and one end of the silicone protective film 41 is sleeved and fixed to the hard transparent plastic tube 3 .

[0046] According to the above technical solution, one end of the silicone protective film 41 can be directly fixed to the second end of the hard transparent plastic tube 3, while the other end of the silicone protective film 41 covers the tail needle 4, reducing the risk of being stabbed by the tail needle 4.

[0047] In one embodiment, a needle protection cap 42 is provided on the outer sleeve of the silicone protective film 41 , and one end of the needle protection cap 42 is sleeved and fixed to the hard transparent plastic tube 3 .

[0048] As in the above technical solution, the risk of being stabbed by the tail needle 4 is further reduced by the needle protection cap 42.

[0049] In one embodiment, the outer side of the hard transparent plastic tube 3 is provided with anti-skid patterns or anti-skid points. For example, the anti-skid patterns are wavy patterns, and the anti-skid points are convex points or concave points.

[0050] The above technical solution, through the anti-slip grooves or anti-slip points, can enable medical staff to hold it more stably and facilitate use.
