In some embodiments, adhesive layer 114 may be disposed on hub 111, or on both hub 111 and wings 113. In order to avoid allergic reactions of the patient's skin to the adhesive layer 114, the adhesive layer 114 is formed of a medical and hygienic adhesive. In addition, a buffer layer, such as a sponge, may be provided between the adhesive layer 114 and the wings 113 in order to enhance the adhesion comfort of the skin of the patient when the lancet assembly 11 is adhered to the skin of the patient.
It should be noted that, because the two-channel arterial blood taking needle is more complicated to operate than the common blood taking device, the medical staff is required to operate the vacuum tube 2 or the anticoagulation injector 3 in sequence in the process of collecting arterial and venous blood samples of patients and extracting blood and gas analysis samples. Some medical staff can vacate one hand to improve efficiency without pressing the blood taking needle head or sticking adhesive tape to the blood taking needle head. This easily causes loosening of the needle (needle tube 112) when operating the vacuum tube 2 or the anticoagulation syringe 3, and even pulls the blood collection needle out of the patient's blood vessel by pulling of the blood collection tube 1.
The utility model arranges the adhesive layer 114 on the puncture needle assembly 11, and the puncture needle assembly 11 is adhered and fixed on the skin of a patient through the adhesive layer 114 after the needle insertion is completed during blood sampling, thereby avoiding loosening the needle tube 112 and even pulling the needle tube 112 out of the blood vessel of the patient due to the pulling of the blood sampling tube 1. In a specific operation, a medical staff holds the needle wing 113 by fingers to perform an alignment needle operation, and after completing needle insertion, the puncture needle assembly 11 is slowly rotated along the central axis of the needle tube 112, so that the adhesive layer 114 on the needle wing 113 is adhered to the skin of a patient, and the needle seat 111 is fixed on the skin of the patient.
Further, as shown in fig. 2 and 3, a protective film 115 is provided on the adhesive layer 114, and the protective film 115 is provided at an end of the adhesive layer 114 remote from the needle wing 113. It will be appreciated that the adhesive layer 114 is protected by the protective film 115 before the dual-channel arterial lancet is used, so that the adhesive layer 114 is prevented from being polluted by long-term exposure to air, and the adhesive layer 114 can be kept sticky during long-term storage by the protective film 115.
Further, as shown in fig. 2 and 3, a protecting tube 1121 is sleeved on the needle tube 112, and the protecting tube 1121 is detachably connected to the needle tube 112.
It can be appreciated that the protective tube 1121 is sleeved on the needle tube 112, so that the needle tube 112 can be prevented from injuring other people accidentally, and meanwhile, the needle point of the needle tube 112 can be protected from knocking against hard objects, so that the needle point is passivated.
Further, as shown in fig. 2 and 3, a connector 116 is provided on the protective film 115, and one end of the connector 116 away from the protective film 115 is connected to the protective tube 1121. The connection piece 116 is used to connect the protection film 115 and the protection tube 1121.
Before blood collection using the two-channel arterial lancet, the medical staff needs to detach the protective tube 1121 and the protective film 115 to expose the needle tube 112 and the adhesive layer 114. In this embodiment, the protective film 115 and the protective tube 1121 are connected by the connector 116, and the protective film 115 can be torn from the adhesive layer 114 by the connector 116 during the process of detaching the protective tube 1121. Can help medical staff to tear the protective film 115 conveniently and quickly. Further improving the blood sampling efficiency of medical staff.
Further, as shown in fig. 2, a first thread 1111 is provided on the end of the needle holder 111 near the protection tube 1121, and the protection tube 1121 is screwed to the needle holder 111 by the first thread 1111.
It will be appreciated that the threaded connection may be more secure than a conventional interference fit connection, thereby preventing the protective tube 1121 from loosening on the hub 111.
Further, as shown in fig. 2, the blood collection tube 1 includes a main blood collection tube 121 and two branch blood collection tubes 13, and the two branch blood collection tubes 13 are connected to the main blood collection tube 121.

Further, one end of the main blood collection tube 121 far away from the branch blood collection tube 13 is connected with the puncture needle assembly 11, and one ends of the two branch blood collection tubes 13 far away from the main blood collection tube 121 are respectively connected with the vacuum tube 2 and the anticoagulation syringe 3.
Specifically, when a venous blood sample and an arterial blood sample are collected from a patient, the branch blood collection tube 13 connected with the anticoagulation syringe 3 is clamped by the clamping device, and at the moment, only the vacuum tube 2 is communicated with the needle tube 112, so that the collection of arterial and venous blood samples is realized. In addition, when the anticoagulation injector 3 is required to be used for drawing the blood gas analysis sample, the blood collection tube 13 connected with the vacuum tube 2 is clamped by the clamping device, namely, only the anticoagulation injector 3 is communicated with the needle tube 112 at the moment, so that the blood gas analysis sample is drawn.
Further, as shown in fig. 2, a second thread 31 is provided at one end of the anticoagulation syringe 3 near the branch blood collection tube 13, a connection base 131 is provided at a position of the branch blood collection tube 13 corresponding to the second thread 31, and the anticoagulation syringe 3 is screwed on the connection base 131 through the second thread 31.
It should be noted that, the anticoagulation injector 3 adopts the connection mode of the screw connection to detachably connect on the connection base 131, so that the connection between the anticoagulation injector 3 and the connection base is firmer, and compared with the connection mode of the interference fit, the anticoagulation injector 3 is firmer and firmer, and the situations of blood leakage or air leakage and the like when the anticoagulation injector 3 extracts blood gas analysis samples are avoided. After the blood gas analysis sample extraction process is completed, the anticoagulation syringe 3 is detached from the connection base 131.
In summary, the present application provides a two-channel arterial blood taking needle, in which an adhesive layer 114 is disposed on a puncture needle assembly 11, and the puncture needle assembly 11 is adhered and fixed on the skin of a patient through the adhesive layer 114 after needle insertion is completed during blood taking, so as to avoid loosening of a needle tube 112 and even pulling out of the needle tube 112 from the blood vessel of the patient due to pulling of the blood taking tube 1.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the utility model.
