For example, it may be a fixed connection, a removable connection, or a unitary construction; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.

Example 1

As shown in fig. 1 and 2, the venipuncture sheath comprises a puncture protective sheath 1 sleeved outside an arm of a human, a simulated skin layer 2 arranged on the outer surface of the protective sheath, and a venous blood vessel model 3 arranged between the puncture protective sheath and the simulated skin layer; the puncture protective sleeve is also provided with a blood container 4 for containing simulated blood between the simulated skin layers; the blood container is in communication with a venous blood vessel model. The puncture protective sleeve adopts the following structure: one end of the puncture protective sleeve is open, the other end is sealed, and the sealed end is in the shape of a finger; the blood container is arranged at one end of the opening; the puncture protective sleeve is matched with the arm and the finger of a person through the arrangement, and the puncture protective sleeve can be better worn and simulated. In addition, the simulated skin layer is made of a silica gel material, so that a simulator can experience a real skin piercing feeling during piercing; puncture protective sheath is made by fiber material, and is deformable, when pasting human skin, can carry out the microdeformation according to actual conditions, thereby better subsides are obeyed on human skin, can make the simulator puncture sense more true, it is the same for the puncture of real person in other words, because wear on people's arm, the person of wearing is just in the simulator with the front, can let the simulator feel be puncturing for real person, so it feels more lifelike, the effect is also better. Meanwhile, the puncture protective sleeve can effectively prevent the puncture needle from injuring a wearer, and the puncture needle cannot penetrate through the puncture protective sleeve when puncturing is carried out, so that the wearer can safely wear the puncture protective sleeve completely, and a puncture simulator can simulate the puncture simulator safely.

During actual operation, only need look for one person and wear on the arm, then puncture simulator can carry out the puncture exercise to because this application has set up venous blood vessel model under the simulation skin layer, has linked together blood container moreover, after the puncture person succeeded in the puncture, can be clear see back the blood phenomenon, the audio-visual understanding puncture condition.

In order to better simulate the puncture of various blood vessels, the number of the venous blood vessel models is multiple, and the shape and the thickness of each venous blood vessel model are different; each venous blood vessel model is at a different distance from the upper surface of the simulated skin layer. By adopting the above arrangement, a simulator can simulate blood vessels including dorsal veins, carpal veins, noble veins and the like, so that a user can utilize the same product to carry out puncture simulation of different parts, the utilization rate of the product is greatly improved, and the input cost is also reduced.

In order to better simulate the puncture blood return exercise, one end of each venous blood vessel model is sealed, and the other end of each venous blood vessel model is communicated with a blood container. By the arrangement, after the puncture is successful, the blood can quickly return, so that the situation of puncture blood return exercise can be clearly known; in order to ensure that the simulated blood can normally return blood, the interior of the venous blood tube model is in a negative pressure state after being sealed, and the simulated blood can normally return after successful puncture.

Preferably, the blood container is of an annular structure, the annular inner wall of the blood container is connected with the puncture protective sleeve, the annular outer wall of the blood container is connected with the simulated skin layer, and the annular side wall of the blood container is communicated with the venous blood vessel model; by adopting the annular structure, the blood container can rapidly provide blood for each venous blood vessel model, and the internal storage space of the blood container can be larger without influencing the thickness of the whole puncture sleeve; meanwhile, the blood replenishing device is convenient to arrange, so that a connecting pipe with a valve can be adopted to be communicated with the blood container, and the connecting pipe extends out of the venipuncture sleeve; therefore, when insufficient blood exists, timely supplement can be performed, and the service life of the product is prolonged.

Example 2

As shown in fig. 3, the venipuncture sheath comprises a puncture protective sheath 1 sleeved outside the arm of a human, a simulated skin layer 2 arranged on the outer surface of the protective sheath, and a venous blood vessel model 3 arranged between the puncture protective sheath and the simulated skin layer; the puncture protective sleeve is also provided with a blood container 4 for containing simulated blood between the simulated skin layers; the blood container is in communication with a venous blood vessel model. The puncture protective sleeve adopts the following structure: one end of the puncture protective sleeve is open, the other end is sealed, and the sealed end is in the shape of a finger; the blood container is arranged at one end of the opening; the puncture protective sleeve is matched with the arm and the finger of a person through the arrangement, and the puncture protective sleeve can be better worn and simulated. In addition, the simulated skin layer is made of a silica gel material, so that a simulator can experience a real skin piercing feeling during piercing; puncture protective sheath is made by fiber material, and is deformable, when pasting human skin, can carry out the microdeformation according to actual conditions, thereby better subsides are obeyed on human skin, can make the simulator puncture sense more true, it is the same for the puncture of real person in other words, because wear on people's arm, the person of wearing is just in the simulator with the front, can let the simulator feel be puncturing for real person, so it feels more lifelike, the effect is also better. Meanwhile, the puncture protective sleeve can effectively prevent the puncture needle from injuring a wearer, and the puncture needle cannot penetrate through the puncture protective sleeve when puncturing is carried out, so that the wearer can safely wear the puncture protective sleeve completely, and a puncture simulator can simulate the puncture simulator safely.

In order to improve the stability of the venipuncture protective sleeve worn on the arm of a human hand, a fixing part 5 for fixing the puncture protective sleeve on the arm of the human body is also arranged at the end part of one end of the opening of the puncture protective sleeve. The fixing piece is arranged, so that the wearing stability of the venipuncture sleeve can be further enhanced, the condition that the venipuncture sleeve slides relative to an arm in a puncture process is prevented, and the puncture effect can be effectively guaranteed and successfully simulated.

Preferably, the fixing piece is an adhesive tape, a bandage or a magic tape; the adhesive tape can be directly stuck on the arm of a person, so that the stability is extremely high; the binding band is adopted, so that the fixation and the disassembly are very convenient; and the magic tape is adopted, so that the magic tape only needs to be stuck once, and the magic tape is very convenient to fix and remove.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
