Abstract
The utility model discloses a thoracocentesis drainage needle which comprises a skin puncture needle, an inner core and a connector, wherein the head of the skin puncture needle is provided with an opening with an inclined section; the inner core takes the shape of a hollow tube; the head end of the hollow tube is a hemispherical or tapered blunt nose; the inner core is inserted in the skin puncture needle; and the connector is connected with the tail end of the inner core. Optimally, a plurality of side holes are formed in the inner core; and the distance between each side hole and the head end is less than 1 cm. The inner core of the thoracocentesis drainage needle is the blunt nose, so that the risks of lung tissue damage and pleura irritation during the puncture process are avoided, and the operating pressure of medical staff is relieved. Meanwhile, through the side holes in the inner core, hydrothorax or pneumatosis can be sufficiently exhausted, and mucoid materials in the hydrothorax can be prevented from blocking a puncture needle.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of drainage needle for thoracocentesis tool, relates in particular to a kind of blunt nosed drainage needle for thoracocentesis tool.
Background technology
It is that the chest surgery is common that thoracentesis extracts hydrothorax or pneumatosis one of wound operation, and the complication of thoracentesis has that pleura reaction, hemothorax, pneumothorax, puncture orifice are hemorrhage, thoracic wall cellulitis, empyema and air embolism etc.Cause the reason of above-mentioned complication to be described below: hemothorax is many owing to puncturing due to the intercostal artery and vein; Pneumothorax can not clamp due to sebific duct, due to leaking-in air, can be punctured due to pin scratches because of patient in piercing process acutely cough lung tissue surface yet; When thoracic wall cellulitis and empyema are puncture, sterilization does not cause strictly that antibacterial infects; Puncture needle contact pleura can cause pleura reaction, and its clinical manifestation is uncomfortable in chest, chest pain, pale complexion, palpitating speed and the discomfort such as dizzy.Above-mentioned complication inevitable factor arranged, but the defective in the design of the thoracentesis needle of prior art is also to cause one of factor that complication occurs.
The syringe needle of the thoracentesis needle of prior art is the tip inclined-plane, and in piercing process, this puncture needle may cause following damage to the patient: the first, and piercing needle has damage intercostal blood vessel to cause the risk of massive hemorrhage.The second, the puncture needle tip diminishes the risk that the impairing the lung tissue causes pneumothorax.The 3rd, needle point is sharp, easily stimulates pleura and produces pleura reaction.The 4th, when running into patient's hydrothorax parcel limitation, the operator need to adjust the depth and the direction of puncture needle repeatedly, and during adjustment, puncture needle more easily stimulates pleura and causes pleura reaction.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, and a kind of blunt nosed thoracentesis needle is provided.
For achieving the above object, technical solution adopted in the utility model is as follows.
A kind of drainage needle for thoracocentesis comprises broken skin pin, inner core and joint, and wherein, the syringe needle of described broken skin pin is diagonal section opening; Described inner core is hollow tubular, and its head end is that hemispherical or taper are blunt nosed, and described inner core inserts in described broken skin pin; Described joint is connected with the tail end of described inner core.
Further, be provided with some side openings on described inner core, described side opening is no more than 1 centimetre apart from the distance of described head end.By side opening is set on inner core, when using drainage needle for thoracocentesis of the present utility model to take out in hydrothorax or thoracic cavity pneumatosis, can extracts more fully hydrothorax or pneumatosis out and prevent that the dope in hydrothorax from stopping up puncture needle.
Further, the length of described broken skin pin is 0.8-1.5 centimetre; Described joint can be connected with syringe or drainage system by flexible pipe.Joint is connected with syringe and is used for the disposable puncture drawing liquid or bleeds, and is used for closed drainage of pleural cavity when joint is connected with drainage system.
The beneficial effects of the utility model are: the inner core of thoracentesis needle of the present utility model is blunt nosed, has avoided damage lung tissue and the risk that stimulates pleura in the piercing process, has alleviated medical worker's operating pressure.Simultaneously, can extract more fully hydrothorax or pneumatosis out and prevent that the dope in hydrothorax from stopping up puncture needle by side opening is set on inner core.

The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is described in further detail.Should be appreciated that specific embodiment described herein only in order to explaining this utility model, and be not used in restriction this utility model.
As depicted in figs. 1 and 2, drainage needle for thoracocentesis of the present utility model comprises broken skin pin 2, inner core 3 and joint 6.The syringe needle 1 of broken skin pin 2 is diagonal section opening, and the length of broken skin pin is 0.8-1.5 centimetre.Inner core 3 is hollow tubular, and its head end 4 is blunt nosed for taper.Be provided with some side openings 5 on inner core 3, side opening 5 is no more than 1 centimetre apart from the distance of head end 4.
As shown in Figure 3, inner core 3 inserts in broken skin pin 2.Joint 6 is connected with the tail end of inner core 3, and joint 6 can be connected with syringe or drainage system by flexible pipe.
The above is only preferred embodiment of the present utility model, is not to limit practical range of the present utility model; If do not break away from spirit and scope of the present utility model, this utility model is modified or is equal to replacement, all should be encompassed in the middle of the protection domain of this utility model claim.
