The invention relates to a soft acupuncture-resistant tubular fabric and a manufacturing method thereof. The tubular fabric comprises a lining and at least two layers of hard material slice woven layers with non-overlapped cracks. The manufacturing method comprises the steps: 1) a tubular fabric die and a lining are placed on a knitting machine, and hard material slices are braided to form a tubular hard material slice woven layer; 2) the number of woven strips is added on the basis of the step 1), or the width of the hard material slices is increased, one or more layers are woven outside the tubular hard material slice woven layers in the step 1), the adjacent woven layers adhere to each other closely, and the cracks of any woven layer and the cracks of at least one additional woven layer do not overlap; for metal slice woven layers, two adjacent layers are welded to each other, to prevent crack overlapping caused by malposition. The tubular fabric made through the method can prevent sharp objects and particularly tapered needles from damaging the human body; besides, the softness is good, and a wearer's activity is not limited.

The invention relates to a puncture instrument, which comprises a puncture needle and a guide wire, wherein the puncture needle is used for realizing puncture on a human body and forms a puncture passage in the body, and the guide wire is suitable for being fed into the human body along a needle tube of the the puncture needle and is remained in the puncture passage to be used as a guide element for next puncture after the puncture needle is pulled out. A use method of the puncture instrument comprises the following steps that a puncture needle core is arranged in the puncture needle to form a whole, and is used for carrying out puncture on a patient; after the puncture to the proper position, the puncture needle core is pulled out for drainage; after the drainage is completed, the front part of the guide wire is fed into the human body along with the tail end of the needle tube of the puncture needle; when the puncture needle is pulled out, aseptic dressing is used for covering the guide wire and fixing the guide wire onto the body surface of the human body; during the puncture in a next time, the puncture needle reaches the puncture position along the guide wire. The puncture instrument provided by the invention is applicable to the patient requiring several times of puncture, and the one-step success of the subsequent puncture is ensured in the use process; the body injury and the psychological burden caused by multi-time puncture on the patient are avoided; the occurrence of complications such as headache and backache is greatly reduced.

The invention relates to a welfare breeding system for laying hens, which effectively solves the problem that laying hens in the existing cage mode cannot move freely, making laying hens timid, rigid in behavior, and weak in bones, etc. The problem of low quality; the technical solution includes the chicken house, which has a breeding rack, a chicken manure treatment device, an egg collection system, an emergency ventilation device on the roof of the chicken house, and a disinfection system at the entrance of the chicken house; the breeding rack is set to two layer; the inside of the breeding rack is provided with a drinking water supply device, the drinking water supply device includes a water pipe, and the outer side of the water pipe is covered with a number of buckles, the lower end of the buckle has a water pipe connected to the water pipe, the lower end of the water pipe has a connected water box, and the lower end of the water box has drinking water There is a drinking water basin at the lower end of the water box, the drinking water head moves upwards, the water inside the water box falls into the drinking water basin, and there is an outer drinking water basin outside the lower end of the drinking water basin, and the inside of the outer drinking water basin is closed with the rise of the water level; the structure of the invention is ingenious, Strong practicability, allowing animals to enjoy welfare.

The invention relates to a vehicle for laying hen field scattering breeding, which can effectively solve the problem of timidity, rigid behavior, fragile bone and the like of the laying hen resulted from no free movement due to crowded hen house under the existing cage breeding mode; the technical solution scheme comprises a scattering breeding vehicle, wherein a breeding frame, a chicken manure treatment device, an egg collecting system as well as a temperature control system are arranged in the scattering breeding vehicle; the temperature control system comprises a master control module which comprises a main control module and eight branch control modules electrically connected with the main control module; the interior of the scattering breeding vehicle is divided into two areas with each on the left and the right side in the front part and two areas with each on the left and the right side in the rear part, each area is provided with a plurality of groups of small positive arc plate ventilation windows arranged on the upper part and a plurality of groups of small anti-arc plate ventilation windows arranged at the lower part matching with the small positive arc plate ventilation windows, the small positive arc plate ventilation windows and the small anti-arc plate ventilation windows are matched to create air circulation in the hen house, each area and the exterior of the scattering breeding vehicle are provided with temperature sensors which are electrically connected with the master control module; the vehicle for laying hen field scattering breeding has strong practicability and brings welfare benefits to the animal.

The invention relates to a puncture instrument and a use method thereof. The puncture instrument comprises a puncture needle and a guide wire, wherein the puncture needle is used for puncturing a human body and forms a puncture channel in the body; and the guide wire is put into the human body along a needle tube of the puncture needle and is left in the puncture channel to be used as a guide part after the puncture needle is pulled out. The use method of the puncture instrument comprises the following steps: placing a puncture needle core into the puncture needle to form an integrated structure to puncture a patient; pulling out of the puncture needle core after puncturing in place, and draining; placing the front end of the guide wire into the human body along the tail end of the needle tube of the puncture needle after drainage is finished; pulling out of the puncture needle; leading the guide wire to be covered and fixed on the body surface of the human body by utilizing a aseptic dressing; and then puncturing again, so that the puncture needle achieves the puncture part along the guide wire. The puncture instrument is suitable for patients need multiple times of paracentesis; with adoption of the puncture instrument, one-time success of follow-up puncture can be ensured when the puncture instrument is used; body injuries and psychological burdens caused by multiple times of puncturing patients can be avoided; and the occurrences of complications such as headache and backache and the like can be greatly reduced.
